Best Time to Visit Khao Yai: Cool Mornings and Clear Views (November–February)

 

 

The cool season brings the year’s lowest temperatures, dry trails and the clearest views. Head to Pha Diao Dai at first light for the sea of mist, or enjoy long, comfortable days at the waterfalls and farms. See our Khao Yai viewpoints guide to plan a dawn trip.

At the resort, cool evenings are made for dinner at Flavours of Khao Yai or Italian dishes at Sapori Cucina. December also brings our festive season celebrations, including the Christmas BBQ buffet dinner and the New Year’s Eve countdown.

 

The Hot Season (March–May): Sunny Days and Slow Pool Afternoons

 

Days are warm and mostly dry, with the occasional afternoon storm in April and May. Plan outings for the morning, then spend the afternoon at the resort pool or with the family at the Little Wild.

 

The Green Season (June–October): Lush Forests and Full Waterfalls

 

The rains turn the forest a deep green and fill the waterfalls. Showers usually come in the afternoon, so mornings are still good for the park. It is the best time to see Haew Suwat Waterfall and Kong Kaew Waterfall at their fullest.
