Aqua Wellness Resort, Playa La Redonda, Nicaragua
Set in a verdant tropical jungle, the tree-house rooms at Aqua Wellness Resort share prime real estate with howler monkeys, birds and butterflies. The resort overlooks the Pacific, and the sound of waves penetrates the shuttered wooden doors that separate the rooms from the wraparound decks (the largest rooms have private plunge pools). With wooden floors and furnishings, the tree houses have the feel of superlative beach cabanas perched high above the sea. If and when guests choose to come down from their treetop hideaways, they can walk down lava-stone pathways and over wooden bridges to the beach for surfing, kayaking or yoga sessions. Rates start at $125; Playa Le Redonda; 917-338-2116; aquanicaragua.com.
