A tough four-hour walk north of El Valle through the jungle and along the shore takes you to Cascada del Tigre, an impressive waterfall with a swimming hole. Local guides charge around COP$50,000 per person. It's an exhausting full-day excursion if you travel both ways on foot – consider hiring a boat (COP$50,000 per passenger, 30 minutes) for the return leg.
You can get a typical lunch (COP$15,000) beside the waterfall and there is an open-air thatched hut where visitors can rent a hammock for the night (COP$20,000) or set up a tent. Guests can access a basic kitchen. The early mornings here are spectacular with the sound of the waterfall backed by a cacophony of birdsong. It's pure unadulterated nature.
