The Erawan Falls are contenders for the most beautiful waterfalls in Thailand, and a must-see if time and budget allow. The entrance fee is 300 baht for foreigners (May 2015), with an additional 20 baht per motorbike. The falls are composed of seven tiers — all of which are picturesque shaded forest areas and great for swimming. Plan to spend at least two hours hiking plus the time you want to spend swimming in the falls. There are also shaded seating areas throughout.
