Khao Yai National Park

Khao Yai National Park is a national park in Southern Isaan, Thailand.

The park is often visited by travellers from Isaan, Bangkok and beyond. There are per-day fees for visitors and vehicles.

Established in 1962, Khao Yai was Thailand's first national park. Today it is the second largest national park in Thailand and, in 2005, the area along with the surrounding Dong Phaya Yen mountains was listed as a UNESCO World Heritage Site.

Tropical moist evergreen forest covers the central area of Khao Yai National Park. The rich diversity of plants (about 2,000 species) astound the new-comer. Towering trees draped in mosses, climbers and epiphytes, tangled trunks of the strangling figs, drooping lianas and spiny rattan palms, delicate ferns, multicoloured lichens and an ever-changing array of fungi. There is always something new to discover in the forest. The park has a diverse plant community of five main vegetation types:

Dry evergreen forests: These forests cover the lower slopes of Khao Yai. There are a number of important plant species found within this type of forest, including Dipterocarps and Hopia. Bamboo is also often found in drier forests.

Dry deciduous forests: These forests also cover the lower slopes of Khao Yai. The most important plant species found within deciduous forests include Afzelia, Xylia and Lagerstroemia.

Tropical moist evergreen forest: Tropical Moist Evergreen Forest covers around 70% of the park, including its central area. Dipterocarps are an important species found within these forests.

Hill evergreen forests: This forest type grows above 1,000 m. In hill evergreen forests, the trees are smaller and ferns, mosses and epiphytes abound. Lithocarps and Catanopsis are among the most important species found here.

Grasslands: These areas are a unique habitat, and provide a grazing area year – round for some of the parks animals. Grassland provides a welcome relief to all the forest . The park mange (burn annually) the grassland to prevent trees from invading and to provide year round grazing for deer, elephants and guar. Wildlife is plentiful (70 mammal species, at least 74 species of herptile and thousands of invertebrates) but often hard to see. Sambar (large, grey-brown, often in groups) and barking deer (smaller, red-brown, usually in pairs or alone) are frequently seen in the grasslands or on spotlighting tours.

Khao Yai's forests are teeming with wildlife and birds. Look up and down and form side, tread softly, and listen carefully to discover the real movers and shakers in the forest. Gibbons provide an excellent morning wake-up call with their mournful hoots. Quiet, patient walkers may catch a glimpse of these tree-living apes. Macaques are often seen on the roadsides. Elephants are sometimes spotted at salt-licks or on the road in the evenings and lucky (?) tourists may spot a tiger in the grasslands during the evenings.

Civets, squirrels, porcupines, and wild pigs add a bit of variety. Snakes and lizards usually make their presence known by a rustle in the undergrowth as you are walking. If you see a snake, treat it as dangerous unless you know otherwise!! Geckos are frequently seen catching insects on building walls and ceilings. Cicadas never stop their scratchy hum. Look up and down and from side to side to spot the real movers and shakers in the forest - the insects and invertebrates. A few Siamese crocodiles (Crocodylus siamensis) have recently been found within the park- some believe the crocodiles were released there while others believe they may indeed be a genuine wild population as this species can be present at higher elevations (such as the Cardamom Mountains of Cambodia.) This species is not aggressive towards humans and rarely grows larger than 3 metres (10 feet.)

Birds: They have lots – over 320 species have been recorded. To the non-expert, birds are often just mysterious whistles, trills and calls, or a flutter of wings and a glimpse of colour. Patience is needed,good binoculars and a bird guide help. Roadsides, the old golf course, grasslands and the watching towers are good places to start . Hornbills are quite easy to spot, and hear the "gak gak gak" laugh of the Indian Pied (often seen in big flocks near Nong Pak Chi Tower in the evenings), or the deep resonant "gok...gok" of the Great Hornbill (usually seen in pairs or alone, the biggest of Khao Yai's hornbills)

Bats: Nearly 1 million insect eating bats live in a cave on the edge of the Park. Drive about 3 km to the north of the Park Chong entrance gate and take a small track on the left-hand side just past a temple. A few hundred metres up here take a right-hand turn and follow the track to the end. You can climb the hill to the cave. Please do not enter the cave - you will disturb the bats. Allow them to come out for about 3 minutes before taking any flash photography.

The lower regions of the park are around 350 m in elevation. Even at this modest elevation and in general throughout the park, you will find a more attractive climate than in nearby Bangkok. The average daily temperature throughout the year is around 23°C.

Like most areas in Thailand the year is split into three seasons: hot, rainy, and cold.

The hot season lasts from Mar-Apr. Daily temperatures can be a bit above the annual average, but it is still very pleasant due to the higher altitude.

The hot season is followed by the rainy season. This lasts from May-October. Average daily temperatures are still high and humidity increases.

The cold season lasts from Nov-Feb. During this time daily temperatures are pleasantly in the low twenties. Nighttime temperatures might require a sweater as temperatures drop.

• Night-time "wildlife spotlighting" is available via pick-up trucks in the early evening. Possible animal sightings include deer, civets, nightjars, porcupines, and occasionally even elephants or other more rare nocturnal creatures.
• Observation towers at Nong Pak Chee or Mo Sing. Early morning is the best time to view the great hornbills, gaur, and sometimes elephants. Gibbons are most active in the early morning.
• About 17:30 thousands of wrinkled lipped bats emerge from a cave 3 km outside the northern gate to begin night time feeding. The bats fly in a ribbon pattern across the sky.
• Slide shows at the visitor center are available on weekends and public holidays.

• There are over 50 km of hiking trails. From easy to hard, one hour to three days. The trails on the map from the visitors center will only have the easier trails. Maps come with English instructions. A guide is recommended for most trails if the tourist has no experience.
• Kayaking and rafting services are available in Prachinburi, in the far southeast of the park.
• Klong Pa Kang-Wang Haew-Dinosaur Footprint. Four-day trek to see a dinosaur footprint.
• Meeting rooms are available with audiovisual equipment for seminars and workshops.

Visit some of the spectacular waterfalls. They might not be the largest you have seen but the scenery is simply stunning. During hot season some waterfalls might be almost dry. The rainy season is the best time to see spectacular falls. During the months of Jun-Aug streams have plenty of water. Under these wet conditions flora also will be at its best.

• Heo Narok Waterfall - The Haew Narok waterfall is the largest waterfalls in the park. It is a three-tiered structure that extends 150 m from the top tier to the basal lake. The waterfall is about 10 km from the south gate along the central road through Khao Yai.
• Heo Suwat Waterfalls - This waterfall runs over a 20-m cliff into a large pool below. It is about 8 km to the east of the visitors center and can be visited easily by car along one of the main easterly roads. It can also be reached by an 8 km hike from the visitor center (walk number 4) which takes about 4–7 hours. It is made up mainly of multiple layers of sandstone conglomerates with large interbeds of basalt.
• Heo Sai Waterfalls - Haew Sai Waterfalls are 700 m north of the Haew Suwat Waterfalls. It is 8 km east of the visitor centre and can also be reached via car or hiking.
• Heo Prathun Waterfalls - Smaller waterfall that is about 1 km north of Haew Sai waterfall.

At Zone 1 in the visitor centre there is a small souvenir shop selling souvenirs from Khao Yai National Park: bags, T-shirts, and most important, leech socks to wear while you're hiking in the jungle to prevent these creatures from getting under your clothing.

Opening hours of the small souvenir shop aren't consistent. So you need just as much luck as you need for spotting wildlife.
