Why Mu Ko Chang Is Worth the Trip

Most of Koh Chang, Thailand’s second-largest island, actually sits inside this national park boundary. That means the jungle ridge running down its spine, the waterfalls tumbling off it, and the reefs scattered around 40-plus smaller islands nearby are all protected under one designation.

You feel the scale of it the moment the ferry from the mainland pulls in at Ao Sapparot or Dan Kao pier. Forested hills rise almost straight out of the Gulf of Thailand, with strips of white sand tucked into the coves below.

Getting There and Getting Around

Koh Chang sits off Trat province in eastern Thailand, close to the Cambodian border. Most visitors fly into Trat Airport, then take a short taxi to the ferry piers at Laem Ngop, followed by a 30-45 minute crossing.

Buses run directly from Bangkok’s Ekkamai station to the pier, timed to connect with ferries. Once on the island, songthaews (shared pickup trucks) cover the main ring road, though many travelers rent scooters to reach trailheads and beaches on their own schedule.

Waterfalls, Trails, and Reefs

The park’s showpiece hikes lead to Klong Plu Waterfall near Klong Prao, a short, family-friendly walk to a swimmable pool, and the tougher trek to Klong Nonsi or Than Mayom falls on the island’s quieter east side. Rangers collect a park entry fee at these access points, separate from any tour cost, so keep small bills handy.

For the marine side, boats depart daily from Bang Bao pier toward Koh Wai, Koh Rang, and other outlying islands, where the snorkeling is noticeably clearer than the mainland-facing beaches. A typical day trip stops at three or four spots and includes lunch on board.

Inland, the jungle interior hides:

• Elephant camps and canopy walkways near Klong Son
• Bang Bao fishing village, built on stilts over the water
• Salak Kok mangrove kayaking trail on the east coast

When to Go

Dry season, roughly November through April, gives you the calmest seas for island-hopping and firmer trails for hiking. December and January bring the coolest, most comfortable air.

Rain picks up from June through October, when waterfalls run fuller but boat trips to outer islands are sometimes cancelled for choppy water. Shoulder months like November and April often mean fewer crowds at the falls without sacrificing much weather.

How to Visit Like a Local

Mu Ko Chang draws heavy tour traffic, especially at Klong Plu Waterfall and the Bang Bao boat piers, so timing matters more than secrecy here.

• Arrive at trailheads right after the 8:30am opening to beat the tour buses.
• Bring cash in small denominations for park entry fees and songthaew rides; card machines are unreliable this far from Bangkok.
• Book snorkeling boats a day ahead in high season, especially around Christmas and New Year.
• Wear reef-safe sunscreen and closed shoes for muddy waterfall trails, not flip-flops.
• Respect the “leave no trace” signage at falls and beaches; rangers do enforce no-littering rules with fines.

The single biggest mistake visitors make is treating this as a beach-only stop and skipping the interior entirely. The jungle trails and mangrove kayaking routes see a fraction of the beach crowds and reward the extra effort with a genuinely different side of the island.

Late afternoon, after most tour groups have cleared out around 3-4pm, is a good window for a last dip at Klong Plu before the park’s 4:30pm close. Just don’t linger past closing, since rangers do sweep the trails at day’s end.

Nearby to Combine With Your Visit

If you have extra time, pair a park visit with White Sand Beach (Hat Sai Khao) for dinner and nightlife, or the Saturday-heavy Klong Prao night market for local street food. Divers based in Bang Bao often extend trips to Koh Rang Marine Sanctuary, technically part of the same park system, for some of the region’s better visibility.
