Twenty years ago, Costa Rica went on a campaign to save the little remaining rainforest it had left to try and nurture the re-growth of areas where 500-year-old trees once stood. The policies that emerged from this decision created new national parks and revolutionized Costa Rican tourism—producing an eco-tourism business model for other countries to follow. One such project was the birth of Rancho Pacifico, whose owners built the resort with the strictest adherence to environmental common sense. The resort limited the cutting of trees, so each of the 11 buildings was placed in the trees. There is also a 250-acre private rainforest preserve—teeming with wildlife, birds, reptiles, waterfalls, and thousands of plants species. Our favorite bathroom is in the Treehaus, with its zen modern design, unmatched ocean and jungle views, natural stone bathrooms, cotton and bamboo fiber linens, and glass double sinks. What takes the cake however are those luscious his and hers over-sized rain showers with step-out gardens and decks. This adult-exclusive retreat is definitely eco-paradise…hearing monkeys rather than air conditioning compressors is, quite literally, a breath of fresh air.
