Rio Perdido

"The first thing guests notice as they approach the600-acre Rio Perdido ecolodge is a large wood-and-steel rotunda that, from a distance, resembles a flying saucer, an award-winning design that houses the resort’s open-air restaurant, bar, and spa. The bungalows are just as stylish: 30 prefabricated cubes are suspended on seven pylons (no trees were cleared during the building process) and feature an airy, modern aesthetic, with twin rolling beds, brass fixtures, and terraces with hammocks sited for gentle breezes. Larger suites are moodier and more romantic, with walls of singed wood and volcanic-stone floor tiles. Soak in the property’s natural springs, which are heated by the activity of nearby Miravalles Volcano, then choose your own adventure. If you’ve worked up an appetite hiking, tubing, or canyoneering, the restaurant serves satisfying Costa Rican casados (rice dishes) and ceviches, which guests can arrange to enjoy from a platform that sits 160 feet above the river that gives the property its name."
