About us
Welcome to ‘Andes by Bike’. We’re two Brits, Harriet and Neil, whose first foray into the world of cycle touring was a trip across Europe in 2008. We followed this up with 19 months of cycling and hiking in South America from 2009-11, an 8 month traverse of the Indian and Nepal Himalaya in 2012-13, then a further year of dirt road biking and volcano climbing in the Andes. Our favourite journeys are on traffic-free routes in the mountains; our favourite places are Peru and the Puna.

Please take a look at our Pikes on Bikes website for journal entries from all our trips and our Flickr stream for some photos.

About ‘Andes by Bike’
After cycling in South America for a few months we realized that despite the many excellent cyclist blogs about the Andes, it was often difficult to find practical information about remote routes. Where we’d encounter water and be able to buy supplies, which way to turn at unsigned junctions, distances – these were the things we thought would be useful to know, but were failing to find. So for the last 12,000km or so we’ve taken route notes and GPS info to publish on this website. We hope you find the information useful for planning and touring in the Andes.

Most of the routes described are quiet, unpaved roads in remote areas, so while ‘Andes by Bike’ won’t tell you anything about the main road from Cusco to La Paz, or from Salta to La Quiaca, it will let you know what to expect if you cross Paso Sico, take the tracks from the Salar de Uyuni to Sajama, or pedal some high altitude routes between Arequipa and Abancay.

In order to keep the information on this site as up to date and comprehensive as possible we’re keen to get updates from cyclists who are currently in the Andes. It would be really helpful if anyone who cycles one of the routes/passes already on the site could add a route update on the relevant page to let others know of any changes, additional information or errors made in the original description. If the original description is still fine please add a comment to this effect, with the date you cycled the route.

Contributing New Route and Pass Information
We also welcome new route and pass contributions. If you cycle a route in one of the countries covered on the site and found it difficult to get information about it beforehand, please consider taking some notes on it and contacting us so that we can create a new route page. The most important things are details of water availability, where supplies can be bought, distances and what to do at junctions in poorly mapped regions. GPS tracks, coordinates, altitudes etc are an additional bonus.

If contributors have blogs or websites we’ll of course be happy to put a link to this on the route page they’ve contributed.

(NB. This applies to all routes cycled by us. On pages contributed by other people we have given details about how they obtained distance/altitude information.)

All distances given were measured using odometers which we calibrated as best we could on our various trips. Distances should be sufficiently accurate to be useful, and are consistent within individual routes; we suspect that for information recorded in 2010-11 distances are overstated by a few percent.

All altitudes given are GPS altitude readings from Garmin eTrex devices. Garmin tell us these are accurate to 30m, and this agrees with what we found in practice. Above about 4,800m we think our readings are consistently overstated by 10-20m.

Amounts climbed
Vertical height gains given are taken from a VDO MC1.0 cycle computer; we adjusted them when we had better data.

All timings given refer to actual time we spent in the saddle and do not include breaks. As far as we know, our cycling speeds are reasonably average – we met faster cyclists, we met slower ones. The length of each route in days refers to how many cycle days we took to complete the route. It does not include rest days.

We’ve given difficulty ratings of between 1 and 5 for each route.

Routes rated 5 are the most difficult and will feature most, or all, of the following: high altitudes, steep roads, large amounts of climbing, bad surfaces, long distances between food and water sources, possibility of extreme weather.

Routes rated 1 are the easiest of those described on this site.

Please take these ratings only as a relative guide of the difficulties and bear in mind that while we’ve tried to be consistent they’re affected by many different factors at the time we cycled.

The ratings only relate to cycling the route in the direction described. While many routes will be roughly the same difficulty irrespective of the direction they’re cycled in, some are much harder in one direction due to altitude gains or prevailing winds.

For all routes we’ve also stated how much we had to push our bikes on that route, to give a rough idea how much other cyclists may find unrideable.

Being Prepared in the Andes
Many of these routes are in high altitude areas of the Andes on quiet roads where help will be a while coming if you get into difficulties. Weather and road conditions can change quickly so we’d recommend gathering as much up to date information as you can before setting out on any of the remoter routes.

The weather in the Andes can be extreme. The lowest temperature we experienced was -20°C, and on a number of occasions we encountered hurricane force winds.

Don’t underestimate the risks of Acute Mountain Sickness at high altitudes. Information about altitude sickness can be found at Altitude.org.

While we’ve made every effort to make the information in the route descriptions and maps as accurate as possible at the date we cycled, please let us know at of any errors by emailing us: pikesonbikes (followed by at, gmail, then dot com).

Some of the questions we’re most frequently asked about cycling in South America are ‘weren’t you scared?’ or ‘was it safe?’ This normally refers to worries about getting attacked or robbed. Like almost anywhere in the world there is a small risk of this, and also like anywhere the risks are mostly in cities, tourist sites, bus stations, etc. Pay attention in these places and take the standard precautions when wild camping (e.g. hiding from the road, avoiding camping on someone’s land without asking permission) and you’ll give yourself a good chance of being among the large majority of cycle tourists who have no problems at all.

By far the biggest danger on any cycle tour in South America comes from traffic on busy, narrow highways. After a few unpleasant experiences on roads plied by trucks and coaches we began avoiding these paved routes and sought out the smaller ripio (gravel) roads which are described on this website.
