At leisure to explore with your guide the magnificent surroundings of La Fortuna (pay any entrance fees locally).
In 1968 the Arenal Volcano erupted after centuries of lying dormant, converting this quiet agricultural town into a hot spot for adventure travel. Many optional activities are available - including the Sky Tram and several ziplines, several different hanging bridges in the treetop canopy where you can search for birds and rainforest wildlife such as sloths and monkeys, a Sloth Trail, La Fortuna waterfall and a visit to Arenal Observatory, with its wildlife and many walking trails around the Arenal Volcano.
You can enjoy kayaking or paddle boarding on Lake Arenal, horse riding, mountain biking, ATV tours or a gentle cruise down the Penas Blanca River. If you are adventurous you can also try river tubing and waterfall canyoning, or venture into a world of stalactites, stalagmites and subterranean species on a visit to the Venado Caves. Alternatively you can simply relax at one of the many hot springs.
Day tours are also available to the Cano Negro Wildlife Refuge, the rainforests of Puerto Viejo de Sarapiqui, the turquoise waters of the Rio Celeste, or across the border into Nicaragua to view the Penas Blancas Massif.
In the evening you can join an optional guided night trail in search of nocturnal wildlife.
