The route begins at La Cumbre pass, at an altitude of about 4,650 metres, and ends 64 kilometres later in the warm, green Yungas region, at 1,200 metres. Almost the entire route runs downhill. The descent takes about five hours with stops: first along asphalt, then down the old gravel road that is known as the "Death Road."
Until 2006, this was the main road connecting La Paz with the Yungas region. In 1995, the Inter-American Development Bank named it the most dangerous road in the world because of its narrow stretches, poor visibility and steep drop-offs. After the opening of a new, modern highway, the main flow of traffic moved there, and the old road became a popular route for cycling tours.
The ride does not demand the stamina of a professional athlete, but confident bike handling is essential. You will need to stay alert for long stretches over bumpy sections and through bends above the drop, and to know how to brake on loose gravel. On this road, unlike the rest of Bolivia, it is customary to keep to the left. Guides warn when to stop and let an oncoming vehicle pass.
The best time for the ride is the dry season, from May to October. During these months there is less rain and better visibility. From November to March, rain is more likely and the road can become muddy and slippery. Still, mountain weather is unpredictable, so it is worth having a spare day in case the ride is cancelled.
An organised tour from La Paz costs between $70 and $160. The price usually includes transport, a bicycle, a helmet, protective gear and a guide. A road toll of 50 boliviano (about $7) in cash is payable separately on site. When choosing a company, read recent reviews and ask about the condition of the bicycles, the size of the group and whether a support vehicle follows the group, where you can sit if you get tired or feel unwell.
Pack warm clothing for the start at high altitude, a light waterproof jacket, sunscreen, insect repellent and water. If the tour ends at a hotel with a pool, a swimsuit and a change of clothes will come in handy; they can be left in the support vehicle.
