Why go, and how to do it well

Sai Rung, the Rainbow Waterfall, is a small waterfall with a pool at its base, about 4 km inland from Pak Weep Beach on the northern half of the Khao Lak coast. It sits on private land among rubber trees, outside the national park, and a marked path of about 100 m leads from the parking lot to the water.

It's the easiest waterfall near Khao Lak, a short stop rather than a hike, and it pairs well with an afternoon on Pak Weep or Bang Sak. Mornings are quieter.
