Travelers yearning to explore prehistoric Stonehenge or Machu Piccu's Inca ruins better start packing, as both are on a list of endangered destinations, according to a British travel magazine. Wanderlust Magazine's (www.wanderlust.co.uk) second annual “Threatened Wonders List” has identified eight top travel picks that have been over-exploited. Most, including the haunting Jordan desert valley of Wadi Rum, made famous in the cinema classic Lawrence of Arabia, are plagued by tourists, poor planning and shoddy security, the magazine said. Travelers should avoid Stonehenge unless they wish to see a carpark and glimpse the stone monoliths from a disappointingly remote viewing area. Avid trekkers should also rethink a trip to Peru's Machu Piccu, which is plagued by trash and encroaching minibus routes. Up to 2,500 tourists a day trample the mountainside ruins, making it impossible to protect against wear and tear. Timbuktu in northern Mali also gets a mention, with British diplomats last year issuing security warnings for the area after the execution of a British traveler. The river town of Yangshuo in China, beachside Tulum in Mexico and Jaisalmer of India also made the list, along with Australia's evocatively-named Bay of Fires, in south Tasmania state.
