October is the gateway to winter in Chiang Mai, which is perfect for exploring its ancient temples, beautiful night markets, and hilltops.

As the rainy season ends, Phuket is once again back with its stunning beaches in October. Patong is for the all-night revelers, while Kata and Karon are more prone to a restful scene. That includes island-hopping to places such as Phi Phi Island or James Bond Island, fresh seafood on the beach with views of a tropical sunset.
