Koh Chang Island Hopping Tour

Koh Chang, the country's second-largest island after Phuket, serves as the departure point for speedboat circuits that thread through shallow coral channels between Koh Wai, Koh Mak, Koh Kham, and the protected reefs of Koh Rang. The Marine National Park, established in 1982, levies a 200 baht conservation fee on foreign adults—revenue that funds ranger patrols and reef restoration projects across the archipelago's 85 documented dive sites.

Bang Bao Pier, a century-old fishing village rebuilt on teak stilts after the 2004 tsunami, now functions as the region's primary embarkation hub. Most island hopping tours depart between 08:00 and 09:00, returning by 16:30 to avoid afternoon squalls that roll in from Cambodia's Cardamom Mountains. The typical circuit covers four to five islands in eight hours, with scheduled stops for snorkeling above staghorn coral beds, shallow-water swimming in the Koh Wai lagoon, and beach landings on Koh Kham's western sandbar. Speedboat operators run twin-engine longtails or fiberglass RIBs, both rated for 15 passengers and fitted with life vests, snorkel sets, and cooler storage for packed lunches.

The question "is koh chang worth visiting" depends partly on tolerance for seasonal variability—monsoon rains close most tours from June through October, while November through February delivers flat seas and visibility exceeding 20 metres. Ferry times from the mainland Trat ferry pier run hourly between 06:30 and 19:00, with the 30-minute crossing depositing passengers at Bang Bao's southern terminus. The Koh Rang archipelago, a 45-minute speedboat run southwest of Koh Chang, remains the system's ecological anchor: a no-take zone where blacktip reef sharks, hawksbill turtles, and barrel sponges thrive in waters protected since 1995. Tour operators rotate their itineraries to distribute visitor pressure, a practice enforced by the Department of National Parks through daily manifests and mooring permits. The result is a structured circuit that reveals the Trat archipelago's shallow-water biodiversity without the overcrowding that has degraded similar sites in the Andaman Sea.
