Thailand Travel Costs at National Parks: 100-500 Baht

Two people walk through the same gate at Khao Yai on the same morning. The Thai pays 40 baht. The foreigner pays 400. National park admission is the bluntest piece of dual pricing a visitor meets, and Thailand travel costs at the gate now run from 100 to 500 baht per foreign adult depending purely on which park you picked — a spread of 400 baht, about $11.85, for what is often an identical day in the forest.

This budget travel guide prices the whole national park fee table for October 2026: what each band charges, which famous parks sit in which band, the gates that quietly charge more than the table says, and the arithmetic of a family day out at the most expensive park against the cheapest. At 33.76 baht to the US dollar, choosing badly costs a couple more than a night's accommodation.

The fee bands that set Thailand travel costs at every park gate

The Department of National Parks put every park into one of four price bands on 7 June 2022, and that schedule still stands in October 2026. The band, not the park's fame, decides your Thailand travel costs at the barrier. Children here means ages three to fourteen.

Band	Foreign adult	Foreign child	Thai adult	Thai child	Parks	Examples
1	100 THB	50	20	10	67	Doi Suthep–Pui, Khao Kho, Khao Lak–Lam Ru
2	200 THB	100	40	20	55	Khao Yai (base rate), Kui Buri, Khao Khitchakut, Tarutao
3	300 THB	150	60	30	9	Doi Inthanon, Erawan, Kaeng Krachan, Sai Yok, Ao Phang Nga
4	500 THB	250	100	50	2	Mu Ko Similan, Mu Ko Surin

Vehicles are charged on top and separately: 20 baht for a motorbike, 30 for a car, 100 for a six-wheeler and 200 for anything between seven and ten wheels. A helicopter is 2,500. The car fee is per vehicle, not per head, so four adults sharing one car contribute 7.50 baht each — the only line on this page where numbers work in a visitor's favour.

Thai nationals aged 60 and over, children under three, monks and disabled visitors enter free. Foreign pensioners get nothing: a 70-year-old non-Thai pays the full adult rate at every gate in the country.

The gates that charge more than the band table

A second instrument dated 19 September 2022 lifted specific gates above their band, and these are the ones that catch budget travel guides out. Khao Yai's Pak Chong and Noen Hom gates charge 400 baht for a foreign adult and 200 for a child, double the band-2 rate. Hat Noppharat Thara–Mu Ko Phi Phi and Mu Ko Lanta charge 400. Khao Laem Ya–Mu Ko Samet and Mu Ko Ang Thong charge 300. Individual dive and island sites have their own prices again: Hin Daeng, Hin Muang, Koh Rok, Koh Ha and Koh Ngai are 400 baht, Koh Wua Talap and Koh Mae Koh 300.

This is why an island boat trip advertised at 1,200 baht with "national park fee not included" lands at 1,600, and why the Thailand travel costs you were quoted for a Phi Phi day are never the whole bill. It is the same pattern we traced across admissions, transport and rentals in our guide to Thailand's dual pricing.

Thailand travel costs at nine popular parks, compared

Park	Foreign adult	Foreign child	Thai adult	What else to know
Khao Yai	400 THB	200	40	Ticket covers entry and exit on one day only
Doi Inthanon	300 THB	150	60	Gates 05:00–18:00; booth takes cash only
Erawan	300 THB	150	60	08:00–16:30, last entry 15:30; bottle deposit
Khao Sok	300 THB	150	40	Charged again at Cheow Lan Lake, plus ~40 THB pier fee
Mu Ko Phi Phi–Hat Noppharat Thara	400 THB	200	40	Almost never included in boat-tour prices
Mu Ko Ang Thong	300 THB	150	40	Koh Wua Talap and Koh Mae Koh priced separately
Mu Ko Similan	500 THB	250	100	Season 15 Oct 2026 – 15 May 2027, day trips only
Tarutao	200 THB	100	40	Band 2; cheapest of the southern marine parks
Doi Suthep–Pui	100 THB	50	20	Collected on the trails since 1 October 2025

The arithmetic: 1,230 baht at Khao Yai, 330 at Doi Suthep–Pui

Take a family of four — two adults, two children aged three to fourteen — arriving in one car, and the same day out prices like this.

Park	Adults	Children	Car	Day total	USD
Khao Yai	800	400	30	1,230 THB	$36.43
Doi Inthanon or Erawan	600	300	30	930 THB	$27.55
Tarutao	400	200	30	630 THB	$18.66
Doi Suthep–Pui	200	100	30	330 THB	$9.77
Mu Ko Similan (boat extra)	1,000	500	—	1,500 THB	$44.43

A Thai family of four doing the identical Khao Yai day pays 150 baht all in. The foreign family pays 8.2 times that. And the gap between the top and bottom rows — 900 baht, or $26.66 — buys two nights in a fan room in Chiang Mai, or a month of mobile data.

Scale it to a trip and the number stops being trivial. A couple spending a fortnight in Thailand and visiting Khao Yai (800), Erawan (600), Doi Inthanon (600), Khao Sok headquarters plus Cheow Lan Lake (1,200, because the lake is charged again) and one Phi Phi boat day (800) hands over 4,000 baht — about $118 — in gate fees alone, before a single boat ticket, guide or bowl of noodles. Almost nobody budgets for that line, which is why it tends to come out of the cash reserve at the worst moment.

Doi Suthep–Pui: the 100-baht park Chiang Mai hikers now pay for

Since 1 October 2025 the park has collected its fee at Pha Lat Nature Trail — the Monk's Trail most visitors walk — along with Huai Kaew Waterfall, Wang Bua Ban–Pha Ngoap Waterfall, Doi Pui and Suan Son. The rate is 100 baht for a foreign adult, 50 for a child, 20 and 10 for Thais. Reaching Wat Phra That Doi Suthep or Wat Pha Lat by the main road still carries no park fee; the temple's own charge is a separate matter, handled the way we set out in our guide to Bangkok temple entrance fees.

For cheap travel Thailand purposes this is the best mountain-park deal in the country: a band-1 price, thirty minutes from Chiang Mai's old city, for one third of what Doi Inthanon charges an hour and a half further down the same road.

Six ways to cut what you hand over at the gate

1. Check the band before you pick the park. Sixty-seven parks sit in band 1 at 100 baht. If the plan is "a waterfall and a walk", a band-1 park delivers it for a fifth of a band-3 ticket.
2. Do the whole park in one day. Khao Yai's ticket covers entry and exit on the day you bought it. Sleeping inside the park and driving out the next morning means a second 400 baht per adult.
3. Fill the car. Thirty baht is thirty baht whether one person or six gets out of it; two people on a rented scooter pay 20 between them.
4. Book on QueQ. The department's e-ticket app covers 155 parks and takes a date, a time slot, the vehicle and each visitor's name. Walk-ins are still admitted, but booked visitors get priority at busy gates.
5. Carry baht in small notes. Gate booths take Thai baht in cash only — no cards, no dollars, and at Erawan the nearest ATM is about 10 km back towards Si Sawat. Draw the money before you leave town, where you can pick your machine and dodge the charges we break down in our Thailand ATM fees guide.
6. Claim the bottle deposit back. Erawan holds 20 baht per plastic bottle carried beyond the second tier and refunds it when you bring the bottle out. Two bottles is 40 baht of your money sitting in a cash box; most visitors walk off without it.

Closures that turn a paid ticket into a wasted day

Thai parks close, and the closures are seasonal rather than occasional. Mu Ko Similan and Mu Ko Surin shut for roughly five months of monsoon every year; Similan reopened on 15 October 2026 and runs to 15 May 2027, with day trips only this season, visitor numbers capped site by site, and late-October sailings regularly shortened by rough water. Phu Kradueng closes its summit and all overnight stays from 1 June to 30 September. Kew Mae Pan on Doi Inthanon shuts seasonally too, and single dive sites inside the marine parks close on their own schedule. Erawan itself shut at 13:00 on 21 April 2026 because of smoke and reopened the next day.

None of that is refundable once you have driven there, so the cheapest move is a phone call or a look at the park's page the night before — the same discipline that keeps an Erawan day trip from Kanchanaburi from turning into a 1,000-baht round trip to a locked gate.

Bottom line: the savings summary

Six figures to carry into the planning spreadsheet, and the Thailand travel tips behind them.

• 100 to 500 baht is the full foreign-adult range. The park you choose, not the day you go, sets the price.
• 1,230 baht is a foreign family of four at Khao Yai for one day. The same family pays 330 at Doi Suthep–Pui — a 900-baht difference, roughly $27.
• 4,000 baht in gate fees is a realistic fortnight for a couple visiting five parks, about $118 nobody puts in the budget.
• 30 baht per car, not per person — and Khao Yai's ticket dies at the end of the day you bought it.
• Cash only, in baht, at every gate, and 20-baht bottle deposits at Erawan are refundable if you ask.
• Check the season. Similan runs 15 October to 15 May; Phu Kradueng's summit is shut all of June to September.

Park tickets are the classic unbudgeted line in Thailand travel costs: small enough to wave through individually, large enough in aggregate to bend a fortnight's spending. Price the whole trip — flights, rooms, transport, food and the admissions nobody counts — with our Thailand trip budget calculator, then decide which 400-baht gates are worth it and which band-1 park gives you the same morning for 100.
