With their curvy, bleached beaches and stunning jungle interiors, Phi-Phi Don and Phi-Phi Leh – collectively known as Ko Phi-Phi – are the darlings of the Andaman Coast. Phi-Phi Don is a hedonistic paradise where visitors cavort by day in azure seas and party all night on soft sand. In contrast, smaller Ko Phi-Phi Leh is undeveloped and hotel-free, its coral reefs and crystal-clear waters overseen by soaring, jagged cliffs, and visited only on day or sunset cruises.
