The Erawan Waterfall is a seven-tiered splendour in Erawan National Park, Kanchanaburi Province, Thailand. Could it be the most beautiful place on earth? Near the entrance to the park is a splendid, aqua-blue waterfall. From here you begin to climb on good trails and as you climb, six more absolutely gob-smackingly gorgeous cascades appear one by one. After your climb, a swim in refreshingly cool water at one of the upper falls is almost mandatory.
