The Nest Tower at the Arenal Observatory Lodge is one of the top attractions in the area. Standing tall at a height of 92 feet, it provides breathtaking 360 views of the surrounding nature and Arenal Volcano on a clear day. Climbing to the top requires ascending over 150 steps and isn't for the faint of heart! But the stunning views at the summit are well worth the effort, and if you're lucky, you might even catch a glimpse of the wildlife in the surrounding rainforest. With the added bonus of a nearby museum showcasing its history, the Trek Tower has something for everyone.
