They cover all kinds of hotels and villas in mainly exotic places, e.g. Kerala and Zanzibar, though they also feature places closer to home, e.g. Andalucia and Greece. So far, they have featured about 600 hotels in 25 countries, though not all are eco...the way to find an eco retreat is to search "by interest" then select "ecotourism" in the right hand box check box (followed by search). There are some real gems in there, including one of my favourite places Papillote Wilderness Retreat.
