Expect to come back a little muddy as you explore the rainforest and meadows surrounding Arenal volcano. Half day tours take guests riding up muddy embankments and romping through giant mud puddles amidst rolling hills and tropical fields. The ATV trails at Finca La Uva farm cover more than ten miles through forest, fields and land destroyed by the 1968 eruption of Arenal volcano.
Bird and Wildlife Watching
Rivers like the Penas Blancas and the Rio Frio (found in Cano Negro) offer some of the richest bio-diverse regions to see countless birds from common species like anhingas, tiger herons, amazon king fishers, toucans, lineated woodpeckers and trogons to rare and endangered species like the roseate spoonbill and the jacana. Other creatures commonly seen around Arenal include armadillos, sloths, anole lizards, coatimundis, caimans, American crocodiles, green iguanas, oriole snakes, pit vipers, emerald basilisk lizards, howler monkeys, capuchin monkeys and spider monkeys. Other great wildlife watching attractions in Arenal include the hanging bridges and Arenal Volcano National Park.
Arenal's canopy tours are famous for the expansive scenic vistas where visitors fly through the air on zip lines attached to giant rainforest trees or rooted in the sides of mountains. Each company offers unique views from different places around Arenal including zip lines over La Fortuna waterfall, underneath Arenal volcano, through the rainforest and beside Lake Arenal. Along the way you can ride zip lines into Arenal river valley (Go Adventure), reach speeds of more than 50 mph (At SkyTrek), or fly 110 feet in the air like a human pendulum on a Tarzan swing (Ecoglide).
Venado Caves is the only underground park in the country. Amateur spelunkers explore the depths of the five million year old caverns with experienced guides. While hiking through the damp, muddy terrain, visitors will cross paths with four different species of bats: the insectivorous sword-nosed and mustached bats, the nectar-loving Pallas’ long-tongued bat and the little-studied greater naked-baked bat. Guided tours last approximately 2.5 hours, and the caves are located one hour from downtown La Fortuna. Caving tours, which include transportation, guide and gear, typically depart by 7:15 a.m. and return to La Fortuna in time for lunch.
Experience the rainforest through the eyes of the monkeys, more than 300 feet above the rainforest floor on one of 16 different hanging bridges.

Toro River (Class III-IV), often a favorite among rafting guides, features the most challenging rapids of any river in the area, but is only open in the wet season (May-Nov.)
Sarapiqui River (Class III-IV), whose entrance is different than those in Sarapiqui, offers fast-paced action with intense and large rapids that require complex maneuvering. While they're not for the faint of heart, beginners will have no problem tackling these rapids.
