There’s no bad time to visit Khao Yai, but each season offers a different experience. Here’s how the year unfolds, and how to choose the right time for your trip.
The three seasons
| Season | Months | Weather | Best for |
|---|---|---|---|
| Cool | November–February | Dry, with comfortable days and cool nights | Hiking, viewpoints, outdoor dining, cosy villa evenings |
| Hot | March–April | Warm to hot days | Pool time, quieter weekdays |
| Rainy (green) | May–October | Showers and lush forest | Waterfalls, which are fullest around June to August |
November to February: peak season
This is the classic time to visit. Clear mornings make the viewpoints spectacular, and evenings can be cool enough for a jacket. It’s also the busiest period, especially at weekends and over the New Year holidays, so book villas and restaurants well ahead.
March and April: hot and quieter
Days are warm, some waterfalls run thin, and crowds ease outside Thai holidays such as Songkran in mid-April. A private pool villa comes into its own now: explore early, then spend the afternoon in the water.
May to October: the green season
Rain brings the forest to life and fills Haew Narok and Haew Suwat. Expect showers, slippery trails and leeches (leech socks are sold in the park). The park may close some viewpoints and trails during this period. In 2025, for example, Pha Diao Dai was closed from June to September, so check the official park website before you travel.
Timing your days
- Wildlife: the first hours after the 06:00 gate opening, and late afternoon.
- Waterfalls: mid-morning, before tour groups arrive.
- Viewpoints: early morning for mist, late afternoon for warm light. Leave time to exit before the gates close at 18:00.
Weekdays vs weekends
Khao Yai is a favourite weekend escape for Bangkok residents. If your dates are flexible, Monday-to-Thursday stays bring quieter roads, easier restaurant bookings and calmer waterfalls.
