9 Options For Ecotourism Travel In The United States (PHOTOS)

Summer is the perfect time for travel, so make your summer vacation count by picking a fun and eco-friendly trip. The International Ecotourism Society describes ecotourism as: "responsible travel to natural areas that conserves the environment and improves the well-being of local people." Whether that means choosing an enticing eco-resort or volunteering for a weekend at your favorite hiking trail or local animal shelter, we here at HuffPost Green want you to get going.

Along the way, beware of greenwashing and don't forget to pamper yourself (and the earth) a bit too. Whether you hop a train to the other side of the country or take a staycation in your backyard, explore your ecotourism options starting with our slideshow. Vote on your favorite ecotourism choices and, as always, tell us your top picks in the comments. Bon Voyage!
