Emerald Steps: Hiking and Swimming the Seven Tiers of Erawan Falls

You round a slow bend in the jungle road and the air changes — cooler, tinged with limestone and damp leaves — and somewhere ahead a layered roar gathers like applause. At the park entrance, bamboo stalls sell sticky rice and cold coconut, and children point at the map showing seven blue-green circles climbing the mountain: the tiers of Erawan Falls. The first cascade greets you like a promise — broad, shallow pools rimmed by ferns. By the time you reach the fourth tier the forest hushes; lianas loop from branch to branch and sunlight knifes down in shafts through the canopy, turning each pool into a plate of jade.
