I’m making a list of all the things I’d like to do during my next trip to Bolivia. Riding a mountain bike from La Paz to Yungas is at the top of my list. I’ll probably go with one of the established mountain biking tour operators. Gravity Bolivia seems to have the most experience organizing mountain biking tours. Other options are Ranabol, and Down Hill Madness. If you’re planning to make this trip, make sure you first read the mountain biking accident article written by Michael Liebreich to understand the types of risks involved. It’s not for nothing that the La Paz-Yungas road is often called the world’s most dangerous road.
