Quiet national park islands now, Koh Tao pinnacles next
Currently Viewing:
Overview
Chumphon is the quiet Gulf of Thailand gateway where you can dive a protected archipelago one day and catch a ferry to Koh Tao the next. Offshore, Mu Ko Chumphon National Park shelters reefs, sea caves, and small islands with shallow coral gardens for snorkelers and deeper slopes for scuba. Signature dives include the HTMS Prab 741 wreck, soft coral and black coral covered rock, and the Ko Ngam island pair where whale shark sightings are possible. On land, expect empty beaches like Thung Wua Laen, seafood night markets, and the Khao Dinsor viewpoint for Sep to Oct raptor migration. Come for low-crowd boat diving, add on world-class pinnacles around Koh Tao, and enjoy southern Thailand at a slower pace.
Chumphon sits on Thailand's Gulf coast and works as both a destination and a launch point.
Expect fringing reefs, soft coral gardens, black coral, and sea anemone fields. Shallow reef flats make snorkel days easy, while the Ko Ngam area and nearby structures offer deeper dives and occasional big-animal surprises.
Chumphon is one of the fastest mainland hops to Koh Tao. If you want iconic Gulf pinnacles like Chumphon Pinnacle or Sail Rock, plan 1 to 3 nights on Koh Tao and treat Chumphon as your quiet reset.
Chumphon is not a party town. It is beaches, seafood, fruit orchards, and nature.
Add a Koh Tao extension for pinnacles and freediving training, then return to Chumphon for a slower final beach day.

Trip callouts
Mu Ko Chumphon National Park protects mangroves, seagrass, and around 40 islands, with fringing reefs forming from 1 m to 8 m and wide shallow snorkel zones on multiple islands.
Compared with nearby hubs, Chumphon's dive traffic is lighter. Expect a more local, Thai-focused vibe and more space at the best sites.
High-speed ferries connect Chumphon to Koh Tao, making it simple to combine quiet mainland stays with world-famous Gulf pinnacles.
Pair ocean days with mangrove paddles, beaches, and seasonal raptor migration viewing at Khao Dinsor (typically Sep to Oct).
scuba
Why Chumphon for Scuba Diving
Chumphon delivers boat diving in a protected island national park, with a mix of shallow coral gardens, deeper reef slopes, sea caves, and a standout wreck. Dive days typically target Ko Ngam Yai and Ko Ngam Noi for coral and cave features, then add the HTMS Prab 741 wreck for a photogenic artificial reef dive. Conditions are often gentler than exposed open-ocean sites, but you can level up by connecting onward to Koh Tao for deeper pinnacles like Chumphon Pinnacle. Local operators such as Sensui Dive run trips and training with a low-crowd, local feel.

What to do when you're not in the water
Chumphon is a practical, quieter base for freedivers who want the Gulf without the crowds. Use it to stage a Koh Tao freedive course (fast ferry access), then return to the mainland for rest days, beach swims, and low-key training. In calm season windows, sheltered bays around Koh Tao support line training and technique sessions in warm water, while Chumphon's island trips add finning and breath-hold practice over shallow reefs.
Chumphon's best snorkeling is built around Mu Ko Chumphon National Park, where fringing reefs can start as shallow as 1 m and stay within comfortable depths for long, relaxed sessions. Several islands are highlighted for shallow reefs, while Thung Wua Laen Beach offers an easy mainland swim option with a gentle slope and a classic beach day feel. Choose calm mornings, wear a snorkel vest if you are not a strong swimmer, and treat the coral as a no-touch zone.
Chumphon is a calm slice of southern Thailand built for slow mornings and nature breaks between ocean days. Split time between beach afternoons on Hat Thung Wua Laen, seafood nights in town, and mangrove and wetland exploration around Ao Thung Kha. If you are visiting in Sep or Oct, plan a dawn or morning trip to Khao Dinsor, a famous viewpoint for raptor migration. The best part is how easy it is to keep plans flexible: you can swap an island day for a waterfall, market, or temple visit if the sea turns rough.
