Get ready for one of the most stunning walks in Northern Thailand, right near the country's highest peak. The Kew Mae Pan Nature Trail is a gorgeous 3-kilometer loop that takes you through a misty, ancient forest before opening up to a breathtaking mountain ridge with panoramic views that seem to go on forever. You'll need to go with a local Hmong guide, which is a wonderful way to support the community, and the whole experience takes about two to three hours. It's a must-do for the incredible scenery, especially if you start early to catch the sea of clouds.
