The catamaran eases away from Koh Samui as morning light thins over the Gulf of Thailand, and the wind pulls you toward a scatter of rocky islets stacked like pages in a sea-worn book.
You’ll visit the archipelago known locally as Koh Si Koh Ha—literally Four Islands, Five Islands—where a single island can hide behind another depending on your angle. These southern isles are a mix of low white beaches and jagged cliffs that host colonies of swiftlets; historically their nests were harvested for bird’s nest soup in Southeast Asian markets. Geologically the islands are limestone and coral-born, the edges pounded into caverns and ledges that thousands of birds use for nesting.
Koh Taen (Koh Tan) is prized for its coral gardens and snorkel-friendly shallows. Koh Madsum offers broad white sand and, less commonly, semi-domesticated boars that amuse visiting families. Small, newer spots such as Koh Rap have begun welcoming overnight campers. The day finishes with a westward cruise timed to catch a tropical sunset.
Practical guide: this is a full-day private charter (about 8 hours). Snorkelling gear, bottled water, light refreshments and fishing rods are provided onboard. Expect open-deck time, sun exposure and short wet entries for swimming; reef-safe sunscreen and a waterproof camera are recommended. The operator notes an all-sales-final policy and may cancel in poor weather, so check forecasts and pack a light wind layer. If you’re after easy snorkeling, quiet beaches and birdlife observation with a private crew, this itinerary delivers an accessible, scenic day on the water.

The islands have a long history of nest‑gathering for the Asian bird’s‑nest trade; collectors traditionally used bamboo ladders on cliff faces to harvest swiftlet nests.
Coral reefs here are sensitive to warming and contact; use reef‑safe sunscreen, avoid touching coral and follow local guidance to reduce marine impact.
