Few things sound more adventurous than hooking yourself into a harness and rappelling down waterfalls and rock faces. Several rivers and streams wind through the lush tropical forests in the Arenal area, and in some areas these moving waters emerge from the jungle in the form of a waterfall. Getting to the waterfalls general includes a bonus tour of some sort, whether in the form of a guided hike, ATV ride or other fun activity. There are numerous tour companies with trained experts who will guide you to and from the waterfalls, take care of safety equipment and explain what to do every step of the way. Here’s a few to get you started: Pure Trek, Arenal Canopy Tour, Desafío Adventure Company and La Roca Canyoneering Adventure.
