Koh Samae San is the real deal for 'places to visit near Bangkok.' You can recharge your batteries in just 2 days and 1 night without needing to take a day off, or even do a quick day trip! It's only about a 2-3 hour drive from Bangkok, and before you even get tired of your playlist, you'll be greeted by bright blue sea views and soft white sandy beaches that make you want to lie down and bask in the sun immediately! Koh Samae San is one of the few islands that has maintained its natural beauty perfectly because the number of visitors per day is limited (only 300 people a day!). This keeps the island peaceful and not overcrowded, allowing the water to remain crystal clear, so clear you can see the sea floor from the beach.

If you're planning to stay overnight around Sattahip, I recommend booking your hotel in advance through the Traveloka app. They offer a wide variety of options including hotels, resorts, and cozy homestays, all with real guest reviews to help you decide. Plus, during certain periods, there are great discount promotions that can help save on your travel budget! Booking is easy, no waiting in line at the counter, and you can be sure you'll have a place to stay. It's the perfect way to travel with peace of mind.

Before heading out to recharge your batteries with the clear seas at Koh Samae San, it’s important to know that this island is different from others. The island has strict environmental controls, so if you're planning to visit, make sure to read everything carefully to know how to enjoy your trip without any hassles.

Koh Samae San is open every day except for the island's conservation holidays (Monday and Tuesday).
Opening hours: 09:00 - 16:00
The last boat back to the mainland departs between 15:30 and 16:00, so don't miss it! Otherwise... you won’t be able to return.
📌 Tip: Arrive at the pier at least 30-45 minutes before the first boat departure to prepare documents, collect your tickets, and board without any rush.

Here’s the highlight for many visitors — the entrance fee to Koh Samae San is quite reasonable compared to other places.
