Great on so many levels

Water flows evenly over seven distinct tiers of packed earth at Huay Mae Khamin waterfall, a remote gem four hours' drive northwest of Bangkok. Part of Khuean Srinagarindra National Park, the falls feature a trail network leading up to each terrace, offering visitors a close-up look at every level of the picturesque cascade. Huay Mae Khamin's famously even flow was interrupted in 2017, when the river feeding it dried up for the first time in recorded history. Park officials closed the area, but the falls were replenished by the rainy season after a few months.
