From almost any part of the country you are within an hour's drive (or less) of what is often a multi-tiered water fall. Many of Thailand's national parks house some genuinely spectacular waterfalls. Pa La-U, Erawan, Namnuang, Sai Yok, Mae Surin and Mae Sa are all noted for particular interest to visitors. Although they are sometimes a bit tricky to get to, a visit to a waterfall is well worthwhile. The areas around the falls are ideal for hikes and picnics, and sometimes even mountain climbing. Of course, swimming is permitted in the waterfall pools, and often or not they are packed with locals giving them a genuine 'community' feel. Visit some of Thailand's key waterfalls.
