History and location


Arenal Observatory Lodge & Trails was built in 1987 as a scientific research station for the famous Smithsonian Institution.


After the sudden and spectacular explosion of the Arenal Volcano in 1968, scientists from the Smithsonian Institution began to frequent the area and camp on the grounds due to its strategic location. The place later became the Arenal Observatory Lodge, which we know today after the construction of cabins and a small hotel that expanded over the years.


It is the only lodge in the Arenal Volcano National Park and is protected from danger by a deep gorge of the Agua Caliente River.


Positioned at the base of the Arenal Volcano and overlooking Lake Arenal, the lodge offers some of the best panoramic views in the region.
