The Experience

The sun is low over Phuket when the minivan delivers you to Thap Lamu pier; steam rises from a thermos and the hull of a speed catamaran cuts the morning glass as the islands ahead sharpen from blue to granite. Within an hour you’re tracing a string of islets whose sculpted rocks and white beaches rise like islands of another climate, and the sea below dares you to look.

Before You Go

Passport required for park entry

This is an 11–12 hour excursion including transfers; bring snacks, cash for small purchases, and a charged phone.
