There are many picturesque hiking trails in the park, both easy and difficult.
For travellers who have come specifically for a weekend hiking trip, Khao Yai National park is the perfect choice. Hiking to the gorgeous waterfalls and wildlife viewpoint towers are the most popular trails. The park officials at the visitor centre provide maps and instructions for hiking. Some challenging hikes like the Haew Suwat Waterfall, it is advisable that you hire a guide for 500 Baht for 3 hours. But the easier treks can be done alone too.
