When To Visit Khao Sok
Khao Sok can be visited all year round but the weather here can be quite unpredictable, especially between June and November when downpours are at their most frequent.
That said, rains usually don't last very long in Thailand so you can always enjoy outdoor activities even if you visit during those months.
For the highest chance of clear days, the months between December to March are highly recommended and it also falls in between the blooming season of Rafflesia, the largest flower in the world, which can often be seen along hiking trails in Khao Sok National Park between February and March so if you want to see these flowers, make sure you align your trip accordingly.
All in all, Khao Sok is an all-year-round travel destination, and no matter when you choose to visit Khao Sok, you are going to have a great time here nonetheless.
