How to get to Khao Yai National Park from Bangkok: go by road. The park is barely three hours from Bangkok by car, according to TAT, so the easiest day trip is a car with driver or a guided tour. You can also take the train to Pak Chong, the nearest station, and hire transport from there. Khao Yai was Thailand's first national park, established in 1962. It covers more than 2,100 square kilometers across four provinces: Nakhon Ratchasima, Saraburi, Prachin Buri and Nakhon Nayok. Pak Chong, in Nakhon Ratchasima province, is the nearest town with a railway station.
Why Khao Yai is worth the drive
Khao Yai is the western end of the Dong Phayayen-Khao Yai Forest Complex, a UNESCO World Heritage Site inscribed in 2005. UNESCO describes five almost contiguous protected areas covering 615,500 hectares and stretching 230 km east to Ta Phraya National Park on the Cambodian border. The complex is home to more than 800 species of animals, including 112 mammals, 392 birds and 200 reptiles and amphibians. It is a stronghold for threatened species such as the tiger, elephant and banteng, and one of the few places where two gibbon species, including the vulnerable pileated gibbon, share a range.
For a day visitor, that means forest, grassland, waterfalls and a real chance of seeing wildlife from the park road. When Time magazine named Khao Yai one of its World's Greatest Places of 2021, TAT noted that rangers had reported more sightings of animals including the Asian black bear and the gaur. Nothing is guaranteed. These are wild animals, and the park does not stage sightings.
Getting there
By car with driver
For a day trip, a private car is the most practical choice. The park's sights are spread along its roads, and a driver lets you stop where you like, wait for wildlife and leave when you are ready. Klook sells a private car charter from Bangkok to Khao Yai. Our guide to hiring a car with a driver in Bangkok explains how these charters work, including what to agree about hours and extra stops.
TAT points out that the approach roads are lined with vineyards, farms and campgrounds, and suggests a loop through PB Valley's wine terraces and roadside dairy farms before the park's own scenic drive. A car makes that easy to fit in.
By train to Pak Chong
Pak Chong station, on the State Railway of Thailand's Northeastern Line, is the nearest and most accessible station for Khao Yai, about 180 km from Bangkok by rail. It is being rebuilt as part of a double-tracking project. From Pak Chong town you still need a hired car or local transport to reach the park gate and get around inside, so the train suits people staying a night rather than a single day. We could not reach the SRT website on September 26, 2026, so check current trains with the SRT (railway.co.th) or the TAT Call Centre on 1672. We could not verify current bus or van departures to Pak Chong either; confirm them with the TAT Call Centre before relying on them.
On a guided tour
A tour takes care of the driving and usually adds a guide who knows where animals have been seen. Klook offers a Khao Yai National Park full-day tour from Bangkok. Check the pickup point, what is included and which trails and viewpoints are on the route before you book, especially in months when some are closed.
What to see in a day
Haew Suwat waterfall
Haew Suwat is the park's best-known waterfall, dropping over a rock ledge into a pool in the forest. A nature trail links it with Kong Kaew waterfall; the Department of National Parks closes that trail for part of the rainy season each year (see the table below).
The visitor center
The Khao Yai visitor center, beside a stream crossed by a suspension walkway, is the natural first stop. Ask the rangers there about current trail conditions, closures and recent wildlife activity before you plan the rest of the day.
Pha Diao Dai viewpoint
Pha Diao Dai is a clifftop viewpoint on a nature trail, looking out over the forest canopy. It closes for the whole rainy season each year, so plan it for the drier months.
Seasonal closures
Parts of Khao Yai close for a set period every year, for safety in the rainy season and to let the forest recover. These are the annual closures on the Department of National Parks list we checked on September 26, 2026 (data dated January 7, 2026):
| Attraction | Closed each year |
|---|---|
| Kaeng Hin Phoeng and Takhro waterfalls | March 1 to April 30 |
| Sarika waterfall | April 1 to April 30 |
| Pha Diao Dai viewpoint | June 1 to September 30 |
| Kong Kaew to Haew Suwat nature trail | July 1 to August 31 |
Extra closures can follow heavy rain, so check the list and the park's own announcements shortly before you travel. Our guide to Bangkok's rainy season covers what the monsoon months mean for trips out of the city.
Fees, hours and tickets
We could not confirm Khao Yai's current entrance fees or gate hours from the Department of National Parks, Wildlife and Plant Conservation (DNP) on September 26, 2026, so we do not print them. Check both with the DNP before you go. TAT reported that from July 1, 2023, visitors had to buy entrance tickets in advance through the QueQ app. Confirm whether that still applies, and whether your tour or driver's price includes park fees.
Wildlife-watching etiquette
Khao Yai's roads cross the animals' own routes. A Bangkok Post editorial noted in 2018 that crashes involving visitors' cars had killed and injured many wild animals in the park. Thailand's Wildlife Conservation Office has published safety guidelines, shared by TAT, which apply in the park:
- Give elephants room. If an elephant is on or near the road, stop at least 30 meters away and keep your engine running so you can move off.
- Stay quiet. Do not honk, shout or use flash photography, and never follow an elephant for a closer picture.
- Do not linger. Long stops for elephants cause congestion and accidents when other cars pull up behind. Tell park officials about elephants on the road.
- Never feed wildlife, and store food securely so you do not attract animals.
- Stay on marked trails, travel in a group, and avoid isolated areas at dawn and dusk, when animals are most active.
- Watch for warning signs. Ears stiff and spread wide, a raised tail or a still trunk mean you should leave the area calmly.
TAT is clear that national parks do not run organized elephant-watching, so any sighting is on the animals' terms. Take your rubbish home as well. In 2020, the BBC reported that the park had begun posting litter back to the visitors who left it, and reminded people that littering in a national park is an offence.
Winery stop on the way
PB Valley Khao Yai Winery is in Phaya Yen, Pak Chong district, on the approach to the park, and TAT has described its vineyard and winery tours. You can book the PB Valley Khao Yai winery tour on Klook. If you taste, drink responsibly and leave the driving to someone else; the legal drinking age in Thailand is 20.
If you cannot spare a day
A trip to Khao Yai takes the whole day. If your schedule is tight, Bangkok has green space of its own: the elevated skywalk at Benjakitti Forest Park and the lake at Lumphini Park are easy to reach. See our Bangkok attractions guide for more.
