Islands of Lake Titicaca, Peru/Bolivia
Score: 61

"Need to divide islands into two categories—floating islands and mountain islands. Floating islands have heavy visitation and are 'set up' for tourism with most of the tiny islands hosting tourists and dressed to impress—all in colorful native costume. Community seems to benefit."

"The Island of the Sun in Bolivia is one of the most staggeringly beautiful places on Earth. However, there is no significant management and tourism is putting the place at risk."

"Two main archeological sites on Isla del Sol [Island of the Sun] include the Incan stone stairway with about one hundred treads, an engineering marvel that combines potable water and a fountain system, and the ceremonial site, mouth of Jaguar. These main visitor attractions, however, have no site interpretation facilities, nor can typical crafts be acquired."

"Preserving cultural identity whilst realizing the economic benefits of tourism is perhaps the greatest issue."

"The Uros [Reed] Islands maintain their real culture, enacting real cultural traditions. The Taquile Islanders were actors manipulated by well-meaning but naive development projects."

"Sewage is dumped into the lake, especially from land settlements."
