Koh Talu, sometimes spelt Koh Thalu, is a small island off Bang Saphan in southern Prachuap Khiri Khan, famous for clear water, coral reefs and a natural rock arch. It lies about 180 km from Hua Hin, roughly two and a quarter hours by car, and is one of the area’s favourite snorkelling escapes.
It suits travellers who love the sea and want a break from Hua Hin’s sandy, shallow beaches: snorkellers, couples, families with confident swimmers and anyone wanting a quiet island feel. It can be done as a long day trip or as part of an overnight stay in Bang Saphan.
Getting there from Hua Hin
Koh Talu Day Trip from Hua Hin: Snorkelling Guide is about 180 km from Hua Hin — around 2.25 hours by car. Book a private car with a Thai driver who waits for you and brings you back whenever you are ready.
About Koh Talu island
Koh Talu is a privately managed island with a resort on it, and day visitors usually reach it with organised boat trips from the Bang Saphan coast. The island’s name refers to the hole worn through the rock at one end, which forms a striking arch above the water.
Conservation is part of the island’s identity, and it has been involved in sea turtle conservation efforts. The surrounding waters are clearer than around Hua Hin, which is why snorkelling is the main draw.
What to see and do at Koh Talu
Snorkelling is the highlight. Day trips usually stop at reefs around the island and nearby islets, where you may see colourful corals, reef fish and, with luck, larger creatures. Visibility varies with the weather and season.
Boats often pass by the famous rock arch, a great photo moment, and many trips include time on a beach for swimming and relaxing. Some excursions also visit neighbouring small islands such as Koh Sang and Koh Sing.
Lunch is typically included on organised trips, but what is offered varies by operator, so check the details when booking.
How to get to Koh Talu from Hua Hin
Boats leave from the Bang Saphan coast, about 180 km south of Hua Hin, roughly two and a quarter hours by car. Because of boat departure times, you need an early start from Hua Hin.
Trains run from Hua Hin to Bang Saphan, but timetables may not fit a morning boat, and you would still need local transport to the pier. Buses and minivans are possible but slow with changes.
For a day trip, a private car with a Thai driver is the most practical option: you can leave early, go straight to the pier and the driver waits for your return to bring you back to Hua Hin the same evening. Confirm your boat booking and departure point before you set off.
Best time to visit Koh Talu
The sea on this side of the Gulf of Thailand is generally calmest from around February to October, with the best snorkelling conditions often in the drier months. From November to January, the northeast monsoon can bring wind and choppy water.
Boats may be cancelled in rough weather, so check the forecast and confirm with your operator the day before. Weekends and Thai holidays are busier.
Day trip or overnight in Bang Saphan?
A day trip is perfectly possible but makes for a long day, with around four and a half hours of driving in total plus the boat trip. If you dislike early starts, consider staying a night in Bang Saphan.
There are resorts on Koh Talu itself and along the quiet Bang Saphan coast. Staying over lets you relax, enjoy the empty beaches and return to Hua Hin at a gentle pace, perhaps stopping in Prachuap Khiri Khan town on the way.
Combining Koh Talu with other stops
On the drive, Prachuap Khiri Khan town with Ao Manao Bay and the Khao Chong Krachok hilltop temple makes a good break. The coastline around Bang Saphan and Ban Krut, with the hilltop temple Wat Thang Sai, is also worth a look.
These stops work best if you stay overnight, as a single day is already full with the island trip.
Reef etiquette and what to bring
Do not touch or stand on coral, do not feed fish and take all rubbish back with you. Reef-friendly sun cream and a rash vest help protect both you and the reef.
Bring swimwear, a towel, a hat, sunglasses, a waterproof phone pouch, motion sickness tablets if needed and some cash. Snorkel gear is usually provided, but bring your own mask if you prefer a good fit.

- Check the sea forecast; boats can be cancelled in rough weather.
- Use reef-friendly sun cream and never stand on coral.
- Pack a waterproof pouch and motion sickness tablets.
