Tree houses are among the most viewed type of property on Airbnb.com; the author secured this one, the Rainforest Tree House in Costa Rica, for $85 per night.
Nearly three decades later equatorial Costa Rican sunlight seeps into my sleeping loft, nestled amid chilamate leaves 20 feet above the ground. A toucan has just passed by the deck of our stilted retreat, which abuts natural hot springs close to the Arenal Volcano some 60 miles north of San José. I descend to the main cabin, where Frances, my partner, heats water for coffee in a tiny, well-appointed kitchen. My childhood fantasies were never this good.
