Puerto Rico's efforts at being eco-friendly don't stop with its Green Lodging Program, and aren't just a government initiative. You'll find that many tour operators take this commitment to heart. I've been on my share of tours around the island, and I've been more than impressed with how so many guides and companies share a common respect for the environment and an awareness and desire to practice sustainable tourism.
These eco-tours are not just tremendous fun; they're also ways to enjoy the best of the island while leaving as small a footprint as possible. Next time you want to get back to the land, you'll find you can hike, walk, kayak, sail, surf, board, glide and zip your way around Puerto Rico.
