A popular day trip from Phi Phi Don is a visit to nearby Phi Phi Lae via longtail or speedboat. The first stop is Viking Cave, a vast cavern of limestone pillars covered with crude drawings. Most boats continue on for an afternoon in Maya Bay, aka "The Beach." If you don't mind thronging crowds (the snorkelers practically outnumber the fish), Maya Bay is a spectacular site. If you get a really early jump on everyone, cruise into a secluded bay and leave first tracks along the powdery sand beach; otherwise, head to secluded Loh Samah Bay, on the opposite side of the island. Loh Samah Bay may, in fact, be the better option. Though smaller, it is as beautiful as Maya Bay but receives less attention.
