This highly recommended bike outfitter and tour agency gets you out on two wheels to all the popular attractions but also to more obscure waterfalls and mountain trails. Owner Francisco is trained in first aid and mountain rescue. Guided day trips run COP$120,000 to COP$300,000. The half-day trip to the Periquera waterfall (COP$130,000) is also popular.
If you want to go it alone, Ciclotrip also rents bikes (COP$90,000 per day) that are a step up from those found elsewhere around town. Staff will help you plan a route and give you a marked-up map to follow and even a cell phone so you can call for mechanical support if you run into difficulties.
