Arenal Observatory Lodge & Spa , Costa Rica

The historic Arenal Observatory Lodge & Spa offers 48 comfortable hotel rooms in various buildings spread over the property, and two unique Costa Rican vacation home rentals.

Arenal Observatory Lodge & Spa is easily accessible from the nearby town of La Fortuna. The lodge is well located to enjoy the many adventure tours in Arenal, such as zip lines, whitewater rafting, hot springs, kayaking, stand up paddleboarding, fishing on Lake Arenal, etc.

Arenal Observatory Lodge & Spa was originally built in 1987 as a scientific research station for the world-famous Smithsonian Institution. After Arenal Volcano’s sudden and dramatic explosion into life in 1968, Smithsonian Institution scientists began frequenting the area and would camp on the family’s land because of its strategic location. They built cabins and a small hotel to take care of them and expanded over the years.

 

The property is uniquely located right between Arenal Volcano and Lake Arenal, you can explore rainforest, waterfalls, streams, 11 kilometers (7 miles) of trails, and see an amazing wealth of wildlife. Arenal Observatory Lodge is a renowned destination for bird watching in Costa Rica, with more than 500 species of birds noted so far in our forest. Nature rises early in Costa Rica. It is worth it to get up at first light to see the howler monkeys and birds that were your alarm clock in the morning.

Enjoy delicious meals in the lodge restaurant with floor-to-ceiling windows for gazing at the Arenal Volcano and Lake Arenal, and a huge observation deck just outside. The Observatory Spa will help you relax with massages and other body therapies.

Walking Trails

Arenal Observatory Lodge & Spa rests in the heart of one of Costa Rica’s largest nature preserves – the Arenal Conservation Area. We are uniquely located within the Arenal Volcano National Park boundaries, where primary and secondary tropical rainforest grow in fertile volcanic soil, creating a rich habitat for birds, butterflies, mammals, reptiles and insects. One of the more iconic sounds of the rainforest at Arenal Volcano is the howler monkeys that you can often hear in the early mornings or late afternoons.

An 11-kilometer (7-mile) network of well-marked and maintained trails crisscrosses our Arenal lodge property, ideal for hiking, horseback riding or mountain biking. These trails give you access to so much local natural beauty, and since they are inside our 870-acre property, you won’t run into crowds when out exploring. An 800-meter (0.5 mile) paved trail allows universal access to explore the gardens and rainforest, and gives excellent views of the Arenal Volcano. The paved trail also is perfect for a short night hike to immerse yourself in the exotic sounds and smells of the jungle after dark.

We recommend our daily free guided walk with our naturalist guide that departs from Reception every day at 8:30 a.m. and goes to the Danta River Waterfall. We also recommend walking our other trails early in the morning or in the afternoon for better wildlife viewing, for cooler weather, nice light and beautiful views of Arenal Volcano, Lake Arenal and the rainforest. On our detailed trail map, which you can obtain from Hotel Reception, 7.5 kilometers (4.6 miles) of the trail network are color-coded into red, yellow, brown, blue, green, and orange to help you keep your bearings. Distances and landmarks also are given.
