Happy hours with a volcano view are only a portion of what guests can enjoy at Arenal Observatory Lodge. With spa treatments, hiking trails, museums, and zip-lining, there is something everyone, ranging from adventurous to relaxing.

Their story

The lodge was built to be an observatory for the Arenal Volcano, Costa Rica’s most active volcano. In 1987, the lodge acted as a research station. The observatory sits on the opposite side of the Agua Caliente gorge, protecting it from the volcano while affording the lodge prime views. Arenal Observatory Lodge and Spa offers guests privacy within nature, as it is the only hotel located inside the Arenal National Park.

The family which owned the land allowed scientists to camp on their land before building the structures that make up the lodge. Over the years the cabins have expanded to a hotel with 48 hotel rooms and two house rentals. This lodge is the closest hotel to the volcano. 

Located 22 kilometers from the town of La Fortuna, the lodge is comfortably nestled in nature while close enough to the outside world. With views of the volcano and Lake Arenal, most guests won’t want to leave!

The lodge sits on 870 acres with 270 of which being primary rainforest. Volcanoes, lakes, and rainforest await you at this lodge. Not only perfectly located, but the lodge is a sustainable eco-lodge rated by the Certification for Sustainable Tourism Program. With its unique location, it is no surprise that the lodge works to protect the environment. Read more about them here.
