Length: 3.4 mi • Est. 1 h 51 m
Start from the park entrance. The first part of the hike is a pleasant walk through the jungle on a very well maintained trail. Approximately 0.8 miles away, you reach the junction with a sign to go down to the waterfall or continue to the sulfur outlets in the river, where two rivers meet to create the blue Rio Celeste. The hike to the waterfall is well maintained with stairs, and you can see an incredible waterfall (it must be one of the most photographed in Costa Rica). After going back up the stairs to the junction, continue on a less maintained trail (can be very muddy at some times of the year) to the point where two rivers meet to create the color blue. Incredible views. It is good to go with a guide to help explain the flora, fauna and many stories about the river and the area in general. Keep in mind: the trail has a schedule to enter and fees apply.Show more

The Arenal Observatory Lodge is the only resort in La Fortuna to be located within Arenal Volcano National Park known for putting visitors right in the middle of pristine rainforest habitat that is up close and personal with the famous Arenal Volcano. The Arenal Volcano last erupted in 1968 but has been in a resting dormant phase since 2010 and is carefully monitored. Staying at the lodge grants you free access to all trails. Visitors can pay $10 per person for access to all 7 miles of the network of trails on property. The resort property has a network of trails taking hikers through open grasslands, woodlands, and rainforests with commanding and spectacular views of volcanoes Arenal and Cerro Chato along the way. Trails are well marked and loop back around to the lodge reception and observatory deck. There is a 0.5 mile paved trail through a portion of the rainforest and gardens. The observatory lodge trails connect directly to the tough hike up to the beautiful volcanic lake and laguna atop the volcano Cerro Chato. The Arenal Volcano National Park is known for showcasing some of the best birding in the world including toucans, umbrella birds, woodpeckers, trogons, oropendolas, hummingbirds, owls, and more with over 500 species identified in their forest. Mammals in the park include anteater, gray fox, coatimundi, paca, peccary, monkeys, ocelot, red brocket deer, and more. Show more
