Verified experiences and guided adventures in the surrounding area.

You step onto the roomy dayboat at first light, salt air cutting through the humid heat as the engine murmurs and the mainland slips away. The captain plots a route between the shallow fringing reefs around Koh Rang National Park and the deeper drop that holds the HTMS Chang wreck, and soon the water below is a patchwork of turquoise, navy and living reef.

Frequently asked questions

Do I need to be a certified freediver?

No formal certification is required to join, but you must dive with a buddy; if alone you can choose the guided freedive option.

Are wetsuits or weights provided?

Basic freedive equipment is available on board, but personal masks and fins for correct fit are recommended; weight systems vary by provider.

What if I get seasick?

Bring medication or acupressure bands—sit forward on the boat, focus on the horizon, and tell staff early so they can assist.

Is the HTMS Chang suitable for beginners?

The wreck area includes deeper sections; many nearby sites are shallow and ideal for skilled beginners with a buddy or a guided freedive session.

History

Koh Chang is part of a protected island group in the Gulf of Thailand; marine protection has focused tourism toward sustainable diving and snorkeling in recent decades.

Conservation

Trips operate inside or near national park waters—avoid touching coral, use reef‑safe sunscreen, and follow crew instructions to reduce disturbance.

Adventure tips

Bring a freedive buddyThis tour requires you to dive with a buddy for safety; if traveling solo, book the guided freedive option.

Use reef‑safe sunscreenApply biodegradable sunscreen before boarding to protect corals and avoid reapplying in the water where possible.

Choose long blades and a comfortable maskLong freedive fins and a low-volume mask reduce energy use and extend bottom time on breath-holds.

Start early for calmer seasMorning departures typically have better visibility and lighter winds—plan to be on the water at first light if possible.

Recommended gear

Low‑volume freedive mask: Improves equalization and reduces drag so you can conserve breath-hold energy.
Long freedive fins: Provide efficient propulsion for deeper or longer dives compared with short fins.
Rashguard or 3mm wetsuit: Protects from sun, jellyfish and keeps you comfortable in cooler early‑season water.
Reusable water bottle: Hydration between dives is crucial in tropical heat; boats typically provide water but personal bottle helps.
