The last place to stay on the path up to the Fin del Mundo, this tranquil hostel is a fine base for hiking to the waterfall and swimming holes. Basic rooms are clean and comfortable and the owner (Spanish-speaking only) is very friendly. It's a tough 30-minute walk up an often muddy path, so try to not to bring much baggage.
Dining options are limited to a small restaurant a 10-minute walk away, but you can use the kitchen for a fee – bring supplies from Mocoa. There's no electricity but there is a small spring-fed pool in the gardens and plenty of greenery.
