Tired of cruise ship pollution, frozen airplane food, or hours of driving in a gas-guzzler to reach your favorite vacation spot? Why not try a weekend getaway that not only provides relaxation but also encourages a healthy and sustainable lifestyle? Get back in touch with Mother Nature while traversing the great North American national parks and resting your head in one of the several lodges that can only be reached by foot (or in some cases, by bike, ski or horse).
