Arenal Oasis Night Walk: 28 Frog Species in a Family-Run Sanctuary

Arenal Oasis is the only wild frog sanctuary in the Arenal Volcano area, and the walk goes through it after dark, which is when the tree frogs and most of the rest of the forest are awake and can actually be found. At least 28 frog species live in the ponds here. The ponds are fed by fresh spring water, and the Rojas Bonilla family plants and maintains the native species of Arenal around them, because the habitat is what holds the frogs. The reserve works as a corridor between the rainforest of the volcano and that of the Rio Burio. The trails past the ponds are flat, and the forest at night is loud. A trained naturalist leads the walk and points out the animals hiding from you, which is most of them. Pick-up is at your hotel at 5:00 pm.
