Enjoy a unique evening exploring the region’s only frog sanctuary. The local Rojas Bonilla family has created Arenal Oasis, a natural wonderland that is home to close to 30 species of colorful tree frogs. Carefully laid out spring water ponds connect the rainforest with the Burio River, allowing for the proliferation of these fascinating creatures. Flat trails gently take you through the forest’s nighttime chorus of croaks and chirps. And the naturalist guide’s expertise will help you spot other hidden wildlife. A singular adventure of surprising twists!
