Jardim Atlantico
Portugal

The Jardim Atlantico hotel on the island of Madeira has been eco-friendly since it first opened in 1993; the 30 environmental awards it's won since are a testament to its dedication. Conservation programs include super-energy efficient systems, constant monitoring of the hotel's impact on the surrounding landscape and a reforestation initiative.

There's also an 8,000-meter "Barefoot Walk," essentially a reflexology massage with every footstep. Guests walk along a path strewn with pinecones, mud, sand, pebbles and the leaves of laurel and eucalyptus trees; each element possesses unique healing properties. At the end of the path is a traditional Madeiran irrigation channel to refresh your feet after the walk.
