Our 20 Favorite Green Hotels

Surrounded by 123,000 acres of protected forests, jagged limestone cliffs, and hidden lagoons, travelers to sister resorts El Nido Lagen Island and El Nido Miniloc Island can take their pick of daily activities: bird-watching, kayaking, rock climbing, or simply watching fish swim below one of the guest-cottages-on-stilts, which are set above the crystalline ocean. The resorts are active in both reef and island conservation, helping to protect giant-clam gardens and supporting the reintroduction of endangered Philippine cockatoos.
