Hi Dave, the trip starts in La Paz and takes all day. People either get the minibus back to La Paz at the end of the day or stay the night in Coroico and then continue on to Rurrenabaque.
Great eye,you will never forget a thing with images like that to jarr your memory. The bolivian mountain biking trip looked awesome. Who did you go with? Does it start from La Paz or have I got my wires crossed? cheers, keep up the good work.
