Can you recommend nice trek in Bolivia, but not overcrowded with tourists? Thanks.
Yes! Head to Sucre and visit Condor Trekkers - they are a not-for-profit organisation run by an Australian guy. They do fantastic trekking that passes by dinosaur footprints, natural craters and sometimes follows original Inca trails. You can choose the length of the trek and their food is great!
All their proceeds goes to helping local projects, so you can visit some of them too. about 4 years ago
The Maragua Crater trek is really nice, I did it without a trekking company and we were the only gringos on the trek that week. There is a village along the way that has cabins set up for tourists and they even cook a meal for you for a nominal price (although not the best thing I have ever eaten.) The cabin is beautiful though. Condor trekkers are a great company I have friends who went on their Market trek and absolutely loved it. about 2 years ago
