Khao Yai National Park

The encounter

Species / spectacle: White-handed and pileated gibbons, great and oriental pied hornbills, wild elephants, sambar deer, civets and macaques; night safaris target nocturnal mammals. One of the largest hornbill populations in Thailand.

How you see it: drive/night safari

Typical duration: A full-day visit is typical; multi-day stays suit serious wildlife watchers.

When to go

Cool-dry November to February is best for comfort and wildlife; the hot season stays cooler at altitude.

Hornbills and gibbons are reliable year-round near the visitor centre; mammals are easier in the dry cool months when vegetation thins.

Best time of day: Early morning and late afternoon for gibbons and hornbills; booked night safaris depart around 7pm and 8pm.

Strong-flowing waterfalls in the rainy season and verdant forest from June to September.

Sightings are seasonal probabilities, not promises - even in peak season nature does its own thing.
