At Arenal Observatory Lodge, nature is bursting at the seams, tropical flora and fauna abound. And all the while, the imposing majesty of the volcano reflects in the mirrored lake at her feet, enhanced by her fiery tantrum-all this right outside your room at the lodge. After having lain dormant for over 400 years, Arenal Volcano erupted violently on July 29, 1968, wreaking havoc with the local population and creating a "lava landscape" for miles around its base.

The Arenal Observatory lodge is located just 1.8 kilometers from the active crater of Arenal Volcano, and is separated from it by a deep river valley. Meals are served in our large main dining room, which features walls of windows opening onto views of the volcano and Lake Arenal. We also have a comfortable bar open from 10:00am to 12:00 midnight everyday.

Smithsonian rooms: Four Smithsonian rooms are located just off the main lodge and dining area. Each of these rooms feature a king-sized bed, modern private bath, and amazing volcano view through it’s over-sized windows. Two of these rooms also feature views of Lake Arenal. Ten Smithsonian rooms are housed in a modern building located about 120 yards from our main lodge, reached via a 134 foot suspension bridge through a small patch of rain forest.

These rooms feature huge walls of glass that provide premiere views of the volcano from the comfort of your bed, or from the two chairs strategically placed for you comfort and enjoyment; varnished wood floors, private bathrooms, and one queen- and one full-sized bed. The Smithsonian also features a viewing deck, a conference room and our own volcano museum, with an active seismograph constantly monitoring the volcanic and seismic activity just outside your door.
