Thailand’s tourism authority publishes annual park closure notices. Confirm the specific attraction is open with the park or operator before travelling; weather can also change access.

The Least Visited Paradise in Thailand
The islands off Ranong might be the least visited paradise in the country. Inside Laem Son National Park, the scatter of islands feels like Phuket or Koh Samui did thirty years ago: untouched, unspoiled, and stunning. We have taken boats out here with almost zero other tourists in sight, and on some stops our boat was literally the only one at the island.
This is the main reason Ranong has become our favorite destination in Thailand. While most travelers head straight to the famous southern islands, this coastline delivers crystal clear water and world class snorkeling at a fraction of the cost, with an old Thailand vibe that is getting hard to find anywhere else.
The Laem Son National Park Islands
Laem Son National Park sits about 60 kilometers south of Ranong city, and its islands are the classic Ranong boat day. The snorkeling at Koh Khang Khao, also known as Bat Island, was incredible: clear Andaman Sea water, healthy coral reefs, and nobody else around. Koh Kam Tok offers pristine beaches, and the uniquely named Japan Island, Koh Jeepun, rounds out a day where each stop managed to top the last.
Our earlier account recorded park entry at 200 baht for adults and 100 baht for children and described arranging boats around Bang Ben Beach. Those were details from the trip, not verified current prices or guaranteed departure arrangements. Confirm the exact islands open to visitors, current charges, departure point and sea conditions with the park and your operator before travelling.
The Private Boat Trip: Ko Hin Pla and Yeepun Island
On our second Ranong trip, we chartered a private boat for a full day visiting three stops: Ko Hin Pla, Yeepun Island, and a snorkeling session at Ko Khang Khao. The water at Ko Hin Pla was some of the clearest we have seen anywhere in the country, and for most of the day we had these places entirely to ourselves.
We were surprised by the quote for our private boat day compared with other trips we had considered. That was our experience at the time. For your own comparison, obtain a written quote that states the boat, passenger count, stops, transfers, equipment and any park fees. A low headline price alone does not tell you whether two trips are comparable.
An Honest Warning: Boats Are Boats
We want to be straight with you, because honest caveats are the point of these guides. On one of our island days, the boat's propeller fell off in the middle of the Andaman Sea on the way back to shore. Our Thai guide pulled off an incredible MacGyver style repair using nothing but wire and rope, and somehow got everyone safely back. It makes a great story now, and it says wonderful things about local seamanship, but it also tells you something real about the boats.
That experience made the practical questions impossible to ignore: who operates the boat, what safety equipment is available, how weather cancellations are handled and how help would be contacted. Wear a suitable life jacket and do not go out if the operator or park says conditions are unsuitable. Our successful return is an account of one day, not reassurance about another boat or another trip.
How to Book
Our filmed trip described arrangements around Bang Ben Beach, south of Ranong city. Start by asking the park or operator which departure point is being used for your exact itinerary. Do not assume an old video's location, fee or operating day still applies.
The easier option, especially if you want everything coordinated, is Meeting Point Travel, the local team that handles tours and logistics for us in Ranong. You can find them on Facebook at facebook.com/Meetingpointkohpayam. We used them and found them genuinely helpful. Whichever route you choose, confirm the intended dates, what is included and how cancellations work before you pay.
Practical Tips for the Day
Bring sunscreen, a hat, plenty of water, and a dry bag for your phone and camera, because you will be in and out of the water all day. Snorkeling is the headline activity, so if you have your own mask and snorkel, bring them. Cash is king for park fees and boat payments in this part of Thailand.
Sand flies were part of our beach experience. Think about insect protection as well as sun protection when packing, and ask a qualified pharmacist or clinician about treatment if you need it. Plan the boat day early in your stay, with another day available if weather changes the itinerary.
Final Thoughts
Island hopping from Ranong is not the polished, packaged experience you get on the famous southern islands, and that is precisely the point. Empty reefs, beaches you share with nobody, a slower pace, and practical lessons we did not expect to bring home.
We have filmed both of our island days for our YouTube channel, including the Laem Son trip with the propeller repair, so watch those to see exactly what you are signing up for. Pair this guide with our complete Ranong travel guide for where to stay and eat, and give the islands their own full day. You will not regret it.
