Rio Celeste Hideaway Hotel

The casitas here sit on a private tapir reserve bordering Tenorio Volcano National Park, which sets the tone immediately. This jungle hotel runs more elegantly than the average eco-lodge, with wraparound rainforest decks, outdoor showers alongside proper bathrooms, a spa, riverside yoga, and a swim-up bar for when the wilderness feels like enough. A Michelin Key recognizes it. The surrounding trails, the electric-blue Rio Celeste, and Arenal's hot springs are right outside.
