Erawan Waterfall

Erawan Waterfall’s seven tiers step down a limestone hillside in Kanchanaburi province, each one pooling into a turquoise, swimmable basin before spilling into the next. Seeing all seven means committing to a real hike, not a five-minute look from a viewing platform — budget the better part of a morning if you want to reach the top and come back down.

The falls take their name from Erawan, the three-headed elephant of Hindu mythology; local tradition holds that the topmost tier’s shape recalls the creature when seen from the right angle. The first two or three tiers are the easy ones: a short, mostly flat walk from the car park to shallow pools where the current is gentle enough for children to wade, and small fish nibble at ankles the same way they do throughout the pools higher up.

Past the fourth tier the trail gets rockier and steeper, and the crowds thin out fast — most day-trippers never go higher than the smooth limestone shelves there, which form natural slides into blue-green water. The last stretch to the seventh and final tier is a proper scramble over wet rock, sometimes with a rope-assisted section near the top; after heavy rain, park staff can close that upper section entirely because the limestone gets dangerously slick.

Insider Tip: Tier four is the one everyone stops at for photos — keep climbing past it and tiers five through seven have the same turquoise water with a fraction of the crowd.

November to April brings the clearest water and the surest footing on the trail. Go on a weekday morning if the schedule allows it — coach parties from Bangkok fill the lower tiers by mid-morning on weekends. Water shoes make a real difference on the wet limestone higher up, and a dry bag is worth carrying if you’re swimming between tiers rather than just paddling at the bottom.
