Foreign visitors pay THB 300 as an adult and THB 150 as a child. That is what we found when we checked in August 2026. Thai nationals pay THB 40 as an adult and THB 20 as a child under the two-tier pricing every Thai national park uses. The cut-off age for a child rate is not identical everywhere.
The VIP speedboat, the kayaking tour and the Red Baron sailing trip have the fee inside the price. Nothing to hand over on the day.
The standard speedboat, the budget big boat and the premium catamaran do not. You will pay before you board or at check-in, so carry cash.
The money goes to the Department of National Parks, which runs the protected area. At Ang Thong that means the rangers stationed at the headquarters on Koh Wua Ta Lap, the patrol boats, the mooring buoys that let tour boats tie up without dropping anchor on the seabed, and the upkeep of everything visitors walk on: the roped viewpoint trail, the stairway to the Emerald Lake platform, the toilets and shelters behind the beach. Rubbish has to be boated off the islands, which is not cheap. Your tour price pays the boat company. The entrance fee is what pays the park.

When the fee is not in your tour price, the crew normally collects it in cash at check-in or on the boat and passes it to the park rangers at the entrance, so carry the amount in baht rather than expecting a card machine at a park station. Keep small notes handy. Rangers board or meet the boat at the park entrance buoys, count heads against the tickets, and wave the boat through, so the whole thing rarely takes more than a few minutes.
On tours that include the fee there is nothing to do on the day at all, which is part of what the higher price bought. Keep the ticket until you leave the park. Spot checks happen at the beaches, and on a busy day the rangers do ask.
Every national park in Thailand runs two price lists, and the gap is usually around five times. The official reasoning is that Thai residents already fund the parks through their taxes, so the gate fee only tops that up, while visitors from abroad contribute at the gate instead. You will see the same two-tier board at every park in the country, from Khao Yai to the Similans, so it is not an Ang Thong quirk and it is not negotiable at the counter. Under the same national rules, Thai seniors over 60, monks and people with disabilities enter free.
The child rate is half the adult rate on both lists. The park department generally works with an age band of about 3 to 14 for a child ticket, while tour operators set their own child ages for the boat seat, and the two do not always line up. This is why our listings state their own child ages and why the number on the park board can differ from the number in your booking. In practice the crew tells the rangers how many adults and children are on board and it is settled in seconds. Toddlers and babies below the child band are not charged at all.
Ang Thong closes every year from 1 November until roughly mid-December, when the monsoon makes the crossing rough and the park gets a recovery break. No tours run and no fee is collected. The reopening date moves with the weather, some years around 10 December and some years closer to 20 December, so if you travel in early December, check that boats are actually going out before you plan the day.
Foreign adult fees across Thailand's national parks run from THB 100 at the smaller parks to THB 500 at the headline ones. The THB 300 charged here sits in the middle of that range: the Similan Islands charge THB 500, several Andaman marine parks charge THB 400, and many mainland forest parks charge THB 100 or 200. All of them price foreign visitors above Thai nationals under the same national policy, so the charge at Ang Thong is standard practice rather than a tour add-on.
Checked 9 August 2026. Fees and inclusion rules can change. Confirm the final listing before payment.

Yes, a child rate applies under the park's current rules. The operator can confirm which age or height definition it uses.
Government fees can change. A tour that excludes the fee passes the current charge through separately.
No. The park fee and a kayaking option are separate items.
