🐘 A Few Facts About Khao Yai
- Khao Yai is Thailand’s first national park, established in 1962.
- It spans 2,206 km², making it the third-largest park in the country. It stretches across four provinces: Nakhon Ratchasima, Saraburi, Nakhon Nayok, and Prachinburi.
- Since 2005, it’s been a UNESCO World Heritage Site as part of the Dong Phayayen–Khao Yai Forest Complex.
- The park’s logo features a deer head — a nod to the graceful Schomburgk’s deer, which once roamed Thailand.
- Wild elephants live here — one of the few places in Thailand where you can see them in their natural habitat. (I actually saw them!)
- Khao Yai is home to over 20 waterfalls. The tallest is Haew Narok (about 150 meters), while the most famous is Haew Suwat — featured in the movie The Beach with Leonardo DiCaprio.

FAQs
Absolutely. Whether you read this guide or check the official website, you’ll quickly see why it’s one of Thailand’s most fascinating national parks. With wild elephants, lush jungles, waterfalls, and incredible biodiversity, it’s a must-visit for nature lovers and adventure seekers.
I recommend staying at least 2 days and 1 night. Trekking alone can take up to 6 hours, and you won’t want to miss camping under the stars or joining a night safari — both essential experiences that make Khao Yai unforgettable.
The best option is to drive yourself — by car or motorbike — so you’re not limited by public transport schedules. We rented a car through Local Rent for 1,300 THB per day and had a fun road trip with friends all the way to the park.
There’s no single best month — it really depends on what you’re looking for. If you’re after roaring waterfalls and a jungle bursting with green, the rainy season from June to September is your window. For hiking and wildlife spotting, the hot season from March to May offers dry trails and active animals. And if you want to enjoy cool air and cozy nights under the stars, the best time to camp is during the cool season from October to February.
Yes — and it’s not uncommon. Wild elephants are often seen crossing roads, especially in the early morning or late afternoon. I personally saw two adults with a baby during my visit!
Not necessarily. Most of the park can be explored on your own, especially the shorter, well-marked trails and general sightseeing spots. However, if you plan to join a night safari or hike on trails #3 to #6, a guide or ranger is mandatory for safety and navigation.
If you’re visiting during the cool season, pack warm clothes — temperatures can drop to 14°C at night. For trekking, wear sturdy shoes and long sleeves to protect against sun, insects, and scratchy plants. Lightweight, breathable layers work best year-round.
