Imagine standing above the clouds, wrapped in cool mountain air, with the scent of pine and wet moss all around you. Welcome to Doi Inthanon National Park, home to the highest point in Thailand and one of the most magical highland escapes in the north.

Imagine standing on the bank of a peaceful river. The water flows gently toward the sea. Birds chirp. It’s calm. Then, from the distance, a low rumble begins. The sound grows—like thunder rolling down a tunnel. And suddenly, a single, massive wave comes surging upriver, flipping direction like some ancient force just changed its mind. Welcome to the tidal bore of the Yatsushiro Sea.
