For walking check out John and Cathy Biggar's "The Andes: a Trekking Guide". It has Bolivian and Colombian chapters (and more), and is quite good.
Also check out Lonely Planet's "Trekking in the Central Andes" -- which is probably a good first call for general trekking, but if you have a bit of experience you might find their times / grades a bit soft. This has chapters for Bolivia, Peru and Ecuador -- but not Colombia.
If mountaineering then Yossi Brain's "Bolivia: A Climbing Guide" (but not rockclimbing). |
