The Fertile Valley in a Desert

We left Cafayate, having a vague plan of heading south towards Mendoza. We had a list of places we might want to stop at to break up the journey, but none sounded that appealing. Instead, we decided to try and make it all the way down to San Juan, just 2 hours north of Mendoza. Importantly, it's a decent base to make a trip to Ischigualasto Provincial Park, a UNESCO world heritage site.

The 'Submarine' - one of the famous rock formations in Ischigualasto

After our 5 hour bus journey from Cafayate to Tucumán, we bought our tickets for the next leg - 11 hours overnight to San Juan. Despite buying the tickets from a company called AndesMar with plenty of time to spare, we still nearly missed it. We stood at the terminal, staring at a lone FlechaBus, thinking that our bus had been delayed. Luckily, I went to find out if anybody knew where our bus was and was told that it was the one that had been sitting there all that time. We should probably have realised that the FlechaBus at the same time, going to the same place and at the same price was ours!

The 'Sphinx' in Ischigualasto

We'd heard about Argentinian buses serving wine with dinner, but hadn't experienced it until now, so had begun to think it was a bit of a myth. We can now confirm that this actually happens! We were served a meal as good if not better than in most restaurants here, with proper metal cutlery and drinks options including red and white wine. The journey was quite comfortable, with large seats that reclined almost horizontally.  But however comfortable a night bus is, we still find that they leave us needing to catch up on sleep the next day. We hadn't booked anywhere to stay and, after looking at a couple of abominable hostels, found a hotel to check in to. Annoyingly, they wouldn't match a price on our favoured hotel-booking website, so we used their wifi while in reception to make a reservation before checking in. This didn't seem the most sensible business decision, as they would now be paying 10%+ commission to the website.

San Juan didn't hold much of interest for us, so we soon set off to San Agustín de Valle Fértil. We'd hoped to hire a car, as we knew that it was impossible to get to Ischigualasto park with public transport. Unfortunately, we'd been in San Juan at a weekend and most businesses in Argentina don't open on a Saturday afternoon or Sunday. Luckily, the incredibly helpful owners of the place we were staying in San Agustín helped us to organise a reasonably priced taxi to take us there.

The lake in San Agustín

The park was worth the effort. The main sights are quite spread out, so the standard thing to do is to drive around in a convoy following a guide, then stop at several points to appreciate the landscape from closer up. The park is home to the oldest dinosaur fossils that we have yet discovered, from the Triassic Period around 250 million years ago. The desert-like landscape is sculpted by rain and wind, creating incredible shapes in the layered rocks. Palaeontologists don't need to dig here - they just wait for a rain shower and see what's been uncovered by the erosion.

After Ischigualasto, we were driven back to San Juan by our hosts, from where we took a bus down to Mendoza. We should be meeting our friends Ralph and Shehnaaz there to explore the famous wine growing region together.

The Nazca Lines - One Of The World's Great Unsolved Mysteries

We arrived in the desert city of Nazca with one intention - to see the famous Nazca Lines. These are a complex series of ancient lines, geometric shapes and stylised motifs, all drawn in the desert and encompassing a huge area. The figures include several designs based on animals and plants, including for example a monkey, a hummingbird and a spider. They are on such a large scale that they can only really be appreciated from the air  - most of the animals are 50-100m long, while the lines are often several km long and 1-3m wide.

The hummingbird figure

The Nazca Lines were created by the Nazca culture and its predecessor, the Paracas culture, between around 500 BC and 500 AD. It would have been a huge undertaking. All the figures and lines were made by clearing away the top layer of dark pebbles and revealing the whiter ground underneath. The lines are so straight that they must have been painstakingly planned and measured - some even theorise that the Nazca must have had hot air balloons to be able to create such precise designs that only become clear from the air. Despite being so old, the geoglyphs have remained in good condition due to the extreme aridity of the desert environment.

Our tiny plane for the Nazca Lines flight

Kev had always wanted to take the flight over the lines, but I was less sure and was very nearly put off by the horror stories of poor safety, horrific air sickness and general very bad organisation! At the last minute I decided to go for it, and was very glad I did. The flight was simply incredible: one of the top experiences of the trip so far. We were in a 6 seater plane with another couple plus pilot and co-pilot. The pilot flew round 12 of the most famous figures, banking first left and then right so that people on both sides of the plane could see. We had amazingly clear views of every figure and could better understand their layout and the sheer immensity of the lines. And no air sickness!

A pair of hands - also sometimes known as the frog

While various theories have been propounded, the purpose of the lines remains unknown. Most experts agree that they probably had some religious significance, perhaps intended as symbols to be seen by the gods above: archaeological evidence shows that ceremonies and festivals may have taken place along them. Other theories link the lines to astronomy and some suggest that they were used as some sort of huge celestial calendar. They could also have been paths leading to water sources - vital when living in such a dry environment. One of the world's enduring mysteries.

In the Cantalloc aqueducts

While in Nazca we explored some ruins from the Nazca civilisation. Firstly the Cantalloc aqueducts, a sophisticated system of subterranean water channels that the Nazca designed for irrigating their crops. They look like interconnected terraces, spiralling down to wells at the bottom, and are still used today. Next the slightly gruesome Chauchilla Cemetery, a burial site from the later Nazca period, still containing mummified human remains in open graves. Interestingly, many of the mummies had headdresses or very long hair styled like dreadlocks. We also visited Cahuachi, the remains of an important ceremonial centre and pilgrimage destination for the Nazca. The ruins here were in excellent condition despite being built of mud bricks, again thanks to the extreme conditions here.

Nazca mummies in the Chauchilla Cemetery 

From Nazca we moved on to the small coastal town of Paracas. We had a long walk around the desert peninsula, admiring the beautiful marine scenery and seeing more flamingoes than anywhere else we've been. The next day we took a boat trip out to the nearby Islas Ballestas, 'the poor man's Galapagos', as many descriptions put it. The wildlife here was stunning - the sky became thick with birds as we approached, and the islands themselves are simply covered in colonies of cormorants, Peruvian boobies and Inca terns, among others. They're also home to Humboldt penguins, sea lions and pelicans and we saw all of these at close proximity. Not the Galapagos, but a pretty good alternative for now!

Playa Roja (Red Beach) - part of the Paracas peninsula 

While in Paracas we happened to be discussing what would happen if a tsunami hit .. and lo and behold the next day after the earthquake in Chile there were tsunami warnings throughout coastal Peru. Fortunately we'd moved on by then 60 km inland to the desert town of Ica, where we enjoyed some wine tasting. Yes, Peru's major wine region is in the desert! There's no comparison with Chilean wine, but the 2012 Petit Verdot was surprisingly good actually. We also visited Ica's excellent museum, and will leave here tonight heading for Ayacucho, up in the central highlands.

So many birds! Peruvian boobies at the Islas Ballestas

Ghost Mining Towns, Mummies and Llamas at 4500m

When Kev last posted we were still in touristy San Pedro de Atacama, trying to deal with extremes of altitude, temperature and aridity. It was thus a relief to arrive in Iquique on the west coast, which was at sea level and relatively warm. There's not much that can be said for the city - it's quite a gritty place, rough around the edges and swathed in mist for 90% of the time. Strangely enough however, it did boast some excellent sushi restaurants and, best of all, it lacked tourists other than than ourselves and Cindy and Julien, the Swiss couple with whom we're travelling at the moment.

Old mining machinery in Santa Laura

The four of us hired a car for the day to visit the nearby mining ghost towns of Humberstone and Santa Laura. The two towns and their surrounding area were one of the world's most important producers of nitrate from the 1880s until 1960 and were declared UNESCO World Heritage Sites in 2005. We enjoyed wandering around the abandoned buildings, both residential and industrial, and imagining the lives of the miners living there. The conditions must have been pretty tough - the towns are in the middle of the desert, in unpleasantly dry and hot conditions. We read that the temperature in the mines could get up to 50ºC. At least Humberstone had a swimming pool they could cool off in!

Walking up towards the Atacama Giant 

We also took the opportunity of having our own transport to go to see El Gigante de Atacama, a huge geoglyph on the side of a  hill in the desert. It is the largest anthropomorphic  geoglyph in the world, at 86m tall, and estimated to date to around AD 900.  It was believed to have magical powers, seen as a shaman or a deity by local people of the time.

Chinchorro mummy, in Museo de Sitio Colón 10, Arica

We moved on from Iquique to Arica, another coastal city that was a lot more pleasant than Iquique. A number of mummies have been found in this area from the South American Chinchorro culture and are on display in local museums. They are the oldest examples of mummification in the world, dating back to as far as 5000 - 7000 BC (2000 years before Egyptian mummies). The main museum in the town showcased some remains as they were found - we walked across a glass floor and could look down at the mummies beneath. Some had red or black clay masks, some had wigs and others were decorated with feathers. Quite a weird experience!

We took a bus from Arica up to Putre, a slightly giddying journey up a winding road to an altitude of 3500m. Our main aim of coming here was to visit Parque Nacional Lauca, which is even higher at an average of 4500m. Quite few tourists come to Lauca on a day trip from Arica  - a little stupid, we thought, as an increase of altitude of 4500m in a few hours is a recipe for disaster. We arrived in Putre in the morning and spent a day acclimatising and admiring the incredible scenery. It's a little like San Pedro, but better, with mountains all around.

The town square and church in Putre

The second day in Putre we organised a tour to Lauca. Our driver was a friendly Venezuelan guy, so as well as enjoying the incredible scenery and wildlife of the park, we gained an interesting insight into life and politics in Venezuela at the moment. Lauca national park was one of the most stunning places we have visited so far, with picture perfect volcanoes and lakes. There were lots of animals - we saw endless llamas and alpacas (I still can't tell the difference!) and also herds of their shy wild relative, the vicuña. Plus, among others, the cute rabbit-like viscacha, giant tagua (giant coots) and flamingoes.

Feeding a llama

You could really feel the altitude up here and we were glad we had had a night in Putre to adjust a little. At one point we had to walk up a hill, not a particularly steep one, and within seconds I was gasping for breath. My heart felt like it was going to burst out of my chest and I had to stop and then walk at a really slow pace in order not to feel like I was dying! For once we were glad that we were driven around for most of the day and only minimal walking was involved.

Vicuñas in Parque Nacional Lauca

We travelled back down to Arica the next day and this evening will be taking a nightbus back to San Pedro, from where we'll head into Bolivia via the famous salt flats.

Touring the Atacama Desert

We were in for a shock arriving in San Pedro de Atacama after our 16 hour night bus. For the majority of our time in Chile, we've been in low season. That was still the case in San Pedro, but the only people in the town are tourists and people selling things to tourists. It's in the middle of the Atacama Desert - the highest (San Pedro is 2,400m above sea level) and driest (some weather stations have never received rain) desert in the world. This makes it an uncomfortable place to be. The temperature fluctuates between scorching hot in the sun, to chilly in the shade, to below 0°C at night. Not great when none of the hostels have heating in the rooms. The extreme aridity painfully dries out your nose, throat and skin.

The tourist-heavy main drag in San Pedro

The main attraction is the surrounding scenery - volcanoes, salt flats, lakes, valleys and the night sky. Despite having learnt the lesson that tours are bad many times before, we decided to go with a tour company in order to see as much as possible. Although the tours were good, we're left feeling a bit flat - there's no effort, and therefore less reward, in being taken to see spectacular scenery in a convoy of minibuses with 10-100 other people. That said, the scenery is spectacular.

The valleys of Valle de la Muerte and Valle de la Luna, both near to the town, have completely different characters. Valle de la Muerte consists of red rocks and dusts in strange formations. Because of the colour, it was originally called the Valley of Mars, Valle del Marte in Spanish. This was mistranslated to Valle de la Muerte, or Valley of Death, and the name stuck. Valle de la Luna, Valley of the Moon, similarly appears like the moon. Much of the rock is formed from salt crystals and gives the valley an otherworldly moon-like appearance.

The Tatio geyser field

Another of the big draws around here is the Tatio Geysers, the highest geyser field in the world at 4,320m. This is now Jo's new highest place record. We set off before dawn to be there for sunrise, and to 'enjoy' breakfast at -10°C. The geysers were stunning against a backdrop of even higher mountains in the early morning light. We also visited some nearby hot springs to relax later that afternoon, although stepping out of the warm water into the frigid shade was painful.





Our final tour was to see the Miscanti and Miñiques altiplano lakes at 4,220m above sea level. These were again beautiful set against the 6,000m volcanoes behind them. We continued on to the Atacama salt flat, surrounded by mountains reflected in the shallow pools of water. This made for perfect photographs of flamingoes ignoring the flocks of tourists.

Us, the Milky Way, and the Southern Cross

The highlight of our stay was a stargazing trip. The Atacama desert has perfect conditions to view the stars - it is so high and dry that there is little atmospheric interference. As well as being able to see the Milky Way and other galaxies (the Magellanic clouds) with the naked eye, there were several telescopes set up for us. We were taken around various amazing views - Saturn, star forming nebula, binary stars and other galaxies amongst them.






We've met up with a Swiss couple that we'd met in Pucón, and we're now hoping to travel with them for a bit around the remaining parts of northern Chile, starting in Iquique.

La Serena and Pisco Tasting in the Elqui Valley

La Serena is the main town of the Norte Chico region of Chile and the scenery during our seven hour journey here was a dramatic change from everywhere else we've been so far - arid, desert-like landscapes, with few plants other than cacti of all shapes and sizes. The temperature is noticeably higher during the day, getting up to the high 20s, but drops a lot at night.

The arid Elqui Valley, near to La Serena

We were lucky to hit gold with our choice of hostel here. La Sombre del Viento, a recently opened place, was more like a boutique hotel than a hostel! We had the best shower of the trip and homemade yoghurt, bread and cake for breakfast every day. Our French host, Marie-Laure, was incredibly welcoming and happy to chat to us about her travels across the world over a pisco sour. We told her she could easily charge a lot more - but she doesn't want to attract only the rich customers. Awesome.

The wonderful hostess Marie-Laure, and her world travel map

We spent our first couple of days here checking out the highlights of the city, namely the Japanese garden and the Archaeological Museum where exhibits included one of the original Moai statues from Easter Island. We also decided to visit the nearby Valle del Encanto (enchanted valley), which is famous for its rock art and archaeological importance. Tour agencies in La Serena offer this trip at exorbitant prices, but we opted to go instead under our own steam. After two hours on two different buses we set off walking the final 5km in the baking heat, but luckily were picked up halfway by a friendly Chilean guy who turned out to work there! The rock art was really amazing, with a mix of petroglyphs (carvings), pictographs (paintings), and also lots of hollowed out depressions in the rock, possibly used to mix paint in. There were also two enormous, 3m wide holes, which were labelled as 'Baños del Inca' - baths of the Inca - although we're not sure how accurate this name is. Most of the art came from the early centuries AD, but they have also found evidence of human habitation here up to 5000 years ago.

Pictographs in the Valle del Encanto

After three days around La Serena, we took a bus into the Elqui Valley and stayed one night in the picturesque, if very backpackery, village of Pisco Elqui. Pisco, a spirit distilled from grapes, is Chile's speciality and we've had many a pisco sour here - a delicious cocktail made from pisco, lemon juice, sugar and egg white. Most production of the spirit happens in the Elqui Valley and we enjoyed the long bus ride there with spectacular views of the valley far below, enclosed by steep cliffs and patterned with vineyards. While in Pisco Elqui we obviously had to try some, so did a short tour of the Mistral distillery (one of the premium brands of pisco), including two tastings.

We've just survived a gruelling 16 hour bus journey to arrive this morning in the desert town of San Pedro de Atacama, which is literally in the middle of the Atacama Desert! More on that next time.
