San Antonio de los Cobres – Olacapato – Catua – Paso Sico – San Pedro de Atacama
This fantastic route through the Puna de Atacama in northern Argentina and Chile is a great way to cross the Andes. The scenery is outstanding throughout as the road passes through wild landscapes of volcanoes, salares and lakes. This is a remote part of the Andes with few settlements so it’s best to take about a week’s supply of food from San Antonio (or San Pedro/Socaire if cycling in the opposite direction). Water can only be found at intervals along the road, so in places a day or two of water needs to be carried – we’ve noted in the description where it can usually be found.
There are a couple of options to choose from on this route. From Olacapato to Argentine aduanas (customs and immigration) we chose to go via Catua as we had heard from other cyclists that the route via Salar del Rincon is very sandy. Though the surface near Catua wasn’t great it was always rideable. On the Chilean side we planned on detouring from the main road to go to Lagunas Miscanti and Miñiques, however the turn off when coming from the east is small and not sign posted, so we missed it. Thus the route described here doesn’t go to these beautiful lakes, and we don’t know the condition of the track to them, however we have since found (and included in the route description) GPS coordinates for the turn-offs.
We thought the isolation and other-wordly landscapes on this route made it a more interesting way to cross from Argentina to San Pedro de Atacama than the Paso Jama to the north, but as the road is unpaved and there are few people around (and little traffic on the middle section of the route) it is a lot more challenging. At all times of year be prepared for strong winds and low nighttime temperatures.
Our camera was broken for the duration of this route, so we don’t have any of our own photos of the wonderful landscapes, so thanks to Steve Fabes for allowing us to use some of his shots.

|10km||Continue through Olacapato on a flat road. Surface fine.|
|72km||Cauchari (3,940m) – a few abandoned buildings and a double junction (signposted). No water. Initially – straight/L to Salar del Hombre Muerto, R to Salar del Rincon and Catua (we went R). Then at next junction – L to Salar del Rincon, R/straight to Catua. We took the Catua road.|
|12km||On Salar de Cauchari (3,940m). Flat. Good surface.|
|84km||Start of climb.|
|11km||Climb up a valley to the pass – easy gradient and an ok surface.|
|95km||Abra de Arizaro (4,330m – GPS03).|
|14km||Descend to Catua. First 2kms on an ok surface, then 12kms of sand and washboard. Nice scenery.|
|109km||Junction – R to Catua, 1 km away (3,980m – GPS04, basic accommodation, basic supplies and water), straight to Aduanas Argentinas.|
|17km||Short climb for 1km then descent to Aduanas Argentinas. Surface for first 4kms is ok, then bad for 10kms (the worst on this whole route), before improving for the last few kms.|
|126km||Aduanas Argentinas (3,830m – GPS05). Water.|
|12km||Gentle climb, ok surface.|
|138km||Paso Sico – the Argentina/Chile border. Some big road signs but nothing else here.|

|149km||Abra Sico (4,458m – GPS06).|
|6km||Descend on ok surface.|
|155km||Low point (4,250m) between Abra Sico and Abra El Laco.|
|4km||Climb on ok surface. Not too steep.|
|159km||SAG post. (4,340m – GPS07). Water. Pity the guys at this hardship posting (though not if they confiscate your fruit/meat or other banned food imports). Great views though.|
|4km||Steep climb on ok surface.|
|163km||Abra El Laco (4,578m – GPS08). The highest point on this route.|
|3km||Descent on ok surface.|
|166km||Mina El Laco (GPS09). Staffed year round by a couple of (bored in off-season) guys. Stock up on water, and they also have internet if you need to make emergency contact with the outside world.|
|34km||Descend to Lago Tuyaito (4,050m) then continue to Salar de Aguas Calientes. Ok surface.|
|200km||Leave Salar de Aguas Calientes from its north-west shore. Beautiful scenery.|
|17km||Climb 200m in 5km, then ups and downs until high point at just over 4,100m. Surface fine. About 14kms after leaving the shores of the Salar de Aguas Calientes is the turn off (GPS10) to Lagunas Miscanti and Miñiques.|
|217km||High point at just over 4,100m.|
|43km||More up and down before a 600m descent to Socaire. Surface still ok. The second turn off to Lagunas Miscanti and Miñiques (GPS11 - which is well signposted and is where you’d rejoin the main road if you’d turned off at the first turn off at GPS10) is about 26kms from the first turn off (GPS10), and about 20kms before Socaire.|
|260km||Socaire (3,270m). Civilization at last! Village with shops. Paving begins.|
|50km||Rapid descent to about 2,600m, then quite flat to Toconao.|
|310km||Toconao (2,500m). Town with tourist facilities.|
|43km||Flat to San Pedro. After 22kms is the turn-off to the new observatory. This is probably the highest paved road in the Americas, but when we asked if we could cycle up it we were told it wasn’t opening to the public until 2012. There’s a barrier across the road so it’s not possible to get past, and I doubt they’ll let you cycle even in 2012 – but if anyone succeeds please let us know.|
