We LOVE the round design of Balamku Inn in Mahahual, Costa Maya. This eco-chic hotel is all about sustainable tourism, right down to the shampoo they provide their guests. The wind and the sun are their power sources, all waste water supports constructed wetlands and when building they take special efforts to protect the endangered trees on their property. No wonder they were nominated one of Mexico's leading green hotels. Check out other fabulous Costa Maya hotels.
