About Khao Yai
Established in 1962 as Thailand's first national park, it is the third largest national park in Thailand. Situated mainly in Nakhon Ratchasima Province, Khao Yai extends into Prachinburi, Saraburi and Nakhon Nayok provinces. Khao Yai is just 3 hours away from Bangkok.
The park covers an area of 2,168 square kilometres, including rain/evergreen forests and grasslands. 1,351 m high Khao Rom is the highest mountain within the park. The average altitude of the national park ranges from 400 to 1000 m above the sea level.
Khao Yai is part of Dong Phayayen-Khao Yai Forest Complex, a World Heritage Site declared by UNESCO, covering 5 protected areas from Khao Yai to Cambodian border. The other protected areas are; Pang Sida National Park, Thap Lan National Park, Ta Phraya National Park and Dong Yai Wildlife Sanctuary.
Some common mammals include elephants, bears, gaurs, barking deer, otters, gibbons and macaques. There haven't been any sign of tiger activity in the park for a while, but camera traps has revealed a significant tiger population in neighbouring Thap Lan and Pang Sida National Park. The park has only one crocodile in the national park and it can be seen on same location along the one of trails. According guides operating in the park, the crocodile was released to the park by the park rangers.
The national park is home to around 300 resident and migratory birds and has one of Thailand's largest populations of hornbills. Some of the interesting birds that can be found in the park are barbets, scarlet minivets, broadbills, pittas, mountain scops-owls, great slaty woodpeckers, collared owlets, blue-winged leafbirds, Asian fairy bluebirds, trogons, drongos and magpies. Many ground dwelling birds such as silver pheasants, junglefowls, green-legged partridges and Siamese fireback are common on the roads and trails. Best time to visit Khao Yai for birdwatching is during the dry months and during March April when the big bird migration happens.
Khao Yai is also a good destination for watching reptiles. The best time is around March-April but with still good activity until October, during the cold seasons it takes a bit more effort to spot them. Reticulated python, Ahaetulla prasina, Chinese ratsnake, Chinese water dragon, water monitor and crested lizards are only few of many species that can be found in the park.

Listed hotels there are ideal for pick up by various tour operators. Some hotels in the area don't like tour operators to pick up their guests and should be avoided for flexibility.
There are few bungalows in two different spots inside the national park, these have to be booked well in advance, the bookings must be done through Department of National Parks, Wildlife and Plant Conservation website. The park has two camping grounds where tents can be rent, see further below "Attractions of Khao Yai" for more info.
Next to the Visitor Center, there is a restaurant, several food stalls, parking area and a short circular trail. The circular trail is the only trail in the park that doesn't require guide accompany. Any other trail must be accompanied by a guide. There are three other restaurant inside the park, one at th Haew Suwat Waterfall, one at the Haew Nerok Waterfall south and one at the junction to the Khao Khiaow road. The Lam Takong Camp Site has also a restaurant but it is not regularly open and the choice of food there during the week-days are instant noodles and snacks.
Few open grassland areas nearby visitor center, on Yod Khao Kiew mountain and further east increases the chance to see some amazing mammals. There are also few saltlicks along the roads to attract bigger mammals such as elephants, gaurs, deer and many more. Due to one elephant damaging several cars over few days in early January 2015, vehicles are limited to enter the park 6 am to 6 pm only. Vehicles already in the park are still allowed to leave until late hours which mean tour operators will still be able to continue with nigh safaris after their day tours.
The park offers many trail options from 500m up to 8km long, all together over 50km making it a great destination for hikers. There are also some longer routes that require guides for up to 3 days hiking. Although the park is very popular among the local tourists, overwhelming majority of the local tourists prefer a picnic style stay at camping grounds and only visits the waterfalls and viewpoints, means most of the trails aren't busy.
There are number of waterfalls in the park, most of them easily accessible by vehicles combined with a short walk. Haew Nerok Waterfall in Khao Yai is one of the highest and most impressive waterfalls in the country. The jump scene from The Beach movie starred by Leonardo Dicaprio is from Haew Suwat Waterfall located 8km east from the visitor center.
Conservation efforts and issues
Despite the good effort from park officials, the illegal logging of rosewood is still a problem in the national park from time to time, but not as much as in the neighbouring Pang Sida and Thap Lan national parks. Poaching with the fragrant wood species like sandal- and aloe woods are a bigger problem in the park, traces of poaching can be found off the common trails in some areas.
According the World Heritage Committee's 38th session (Doha, 2014), the illegal logging of Siamese rosewood (D. cochinchinensis) and other trees are escalating both in intensity and violence in Dong Phayayen-Khao Yai Forest Complex.
The paved and well maintained roads results in visitors and park officials driving well above the 60km/h speed limit, which is already too much for a national park. During our multiple visit to the park we have seen park rangers driving above 80 km/h.
Run over by cars, dead or injured snakes is a common sight on the roads, sadly injured pythons are seen far too often. Visitors we have spoken to has seen macaques carrying dead babies killed in accidents, others seen injured adults. We have seen too many times that park rangers and visitors not slowing down when they approach macaques on the roads, driving by very careless, nearly hitting them.
While the high speed issue is an ongoing major problem, we have heard stories from some visitors that they've got fined for stopping by on road side to see wildlife, like gibbons, macaques and hornbills just because they are slowing down the traffic.
The rainy season is May to October with high humidity. Avarage temrepatures are 27 degrees during the day and 13 degrees during the night, perfect season for the waterfalls.
The cold season is November to February with clear and sunny sky. Average temperatures of are 22 degrees during the day and down to 9-10 degrees during the night.
The hot season is March to April, humid with avarage daily temperatures 20-30 degrees during the day and 17 degrees during the night.
Attractions of Khao Yai
There are several interesting trails to few directions around the visitor center area as well as restaurants and a kiosk. The loop trail behind the visitor center is a short one, around 800m long, there is no guide requirement for this trail. Half way through this loop trail, there is a trail-head for a 8km trail that will lead east all the way to the Haew Suwat Waterfall. This trail strictly requires a guide as people has lost their way in the past, spent few nights in the jungle until found.
Although the area around the visitor center is known to be very busy it is one of the best places to spot birds in the park, kingfishers and hornbills are quite common.
There are two camp sites within the park boundaries, both with toilets, showers, parking spaces. Tents are available for rent from 150B, accessories such as sleeping bags, pillows, blanket, canvas etc for 15-50B each. The area around both campsites are ideal for hiking.
When leaving the tents, macaques will visit them soon or later. If the door is closed, monkeys may tear it apart. It is advised to leave the doors and any bags inside open. Any smaller bags or anything a monkey may mistake for a food package should be left open.
The first campsite has a minor restaurant which is not always open. It is relatively easy to get to the restaurants around HQ by hitchhiking.
During the cold season November-February the night temperatures may fall down to 9-10 degrees. Warm cloths are recommended for convinient sleep in the tents but also for early morning/late evening hiking or when using motorbikes.
Lam Takong Camp Site
This first campsite 6km from the visitor center is quite central to most other attractions around the national park.
There is a trail over the bridge north from the campsite which leads to some open grassland areas, very ideal for searcing wildlife activity, elephants do show up on the roads around campsite from time to time.
Malayan porcupines visits this campsite every night, so if you have a torch you can easily spot them. If you approach them gently, you can get as close as few meters and observe their beauty.
For visitors with motorbikes more fuel can be bought from the house at the entry if needed. The elder couple in the house also cooks some basic food when the restaurant closes around 5-6pm, often only instant noodles or sticky rice that can be mixed with fish in can.

This route is also home to many great mid size lizards, we saw three different species in same day, one of them Chinese water dragon. The thail ends at the end of main road few hundred meters from Haew Suwat Waterfall.
There are some fruit trees in the camping site frequently visited by some very colourful birds such as bulbuls, barbets, pigeons and many more if it is right season for the fruits. Also, 40 m downhill the forest from behind the first set of toilets on north side there is a "secret open space" where some exciting birds such as orange-headed thrush, white-rumped shama and Siberian blue robin can be seen frequently.
Pocupines and civets are common during the night.

It is located 4.5km out from the north gate of the national park. See the marker on the map for the location of a trail leading to the cave.
Khao Yai has many waterfalls, most of them easily accessible by car combined with a short trail, some needs longer hiking with guide assistance.
Haew Narok Waterfall
With the highest one at 80m, this three tiered waterfall has total altitue of 150m and is the biggest waterfall in Khao Yai National Park. It is situated approximately 10km from south gate towards the north gate on the main road (road 3077). Waterfall is accessible through a 600m trail off the road. There are toilets and a restaurant as well as a parking area where the trail begins.
The short trail is also a great place to find some birds, lizards, macaques and possibly elephants.
Right before walking down the stairs to the view point there is a povilionish rest area where a 600-800m trail starts. The trail has no sign or any imformation. This trail will lead to a much better view point where the waterfall can be seen from a higher point.
If you plan get to Haew Narok with a motorcycle, there is a small shop 10km south right outside the south gate where you can buy more fuel if needed.
There are also number of saltlicks on the main road north from Haew Narok Waterfall. Elephant activity in this area is very common.

Khao Paeng Ma - Gaur viewing area
Khao Paeng Ma is montane reforestation site covering 8 km² area, located 68 km from the northen gate right outside the northeast corner of the park, it is not really part the national park. In the rainy season of 1995, only couple of years after the project started, a smaller group of gaurs showed up on the area regularly. When the sighting brought to authorities attention, Wildlife Fund Thailand (WFT) decided for a more strict plan to protect the area from the poachers. Since than the gaur population in the area increased, but the serious threat from the poachers still continues.
The area is an ideal place with much better possibilities to see gaurs than inside the park. It is a popular place among the locals and can be quite busy during the week-ends. The road through the site to the visitor center is a dirt road and very bumpy, it requires a 4WD. A 1.8 km long trail starting from visitor area will lead to a watchtower 200 meters into the trail and continue to nine scenic viewpoints.
Khao Paeng Ma Ranger Station on the west side of the forest area is a non-hunting area, another very good location to see gaurs.
