The Mae Pan Waterfall in the Doi Inthanon National Park in Chiang Mai Northern Thailand, flows year round, but like all waterfalls in Thailand it is a lot more impressive in the wet season.
Although it is not the biggest, it is claimed to be the longest. In total, it is approximately 100 metres from top to bottom.
You will find it on the road leading to Doi Inthanon, approximately 16 km from Mae Chaem, It is well signposted and the falls are located about 10 minutes walk from the parking area.
While you are there, providing the weather is kind to you, I recommend that you take some good walking shoes and walk the trail along the ridge. Make sure you take your camera and charge your battery as you will get lots of opportunity to take some photos of some spectacular mountain views. (assuming the weather is kind to you)
