The Spa at Arenas Del Mar Beachfront & Rainforest Resort

"The seven three-story buildings that house the 38 rooms look somewhat out of place amid the leafy environs; their sand-brick-encased windows and concrete staircases could have come from Miami, while marble-and-mosaic-tile bathrooms and heavy curtains make the rooms feel more city hotel than ecolodge; still, they’re spacious and comfortable, and many have spectacular ocean views"

"Take in Manuel Antonio National Park’s sparkling white sand beaches, clear waters, coastal rain forest and mangrove swamp, all filled with abundant wildlife: 109 mammal species and 184 types of bird"

"Rooms here are equipped with spacious balconies, the rain-forest hiking trails are extensive, and the entire place is carbon neutral: solar power heats the water, and electric carts carry guests around the resort"
