One of the most visited destinations in Tamenglong is the River Barak and the accompanying famous seven waterfalls. The seven waterfalls are at close range adding to the beauty of the place. The Barak River that flows through Tamenglong is a major source of irrigation and water to the district. Spending a day picnicking on the banks of the river is one of the best ways to spend a holiday.
Since tourism in Tamenglong is still in its nascent stages, the seven waterfalls have remained more or less untouched magnifying the beauty of the falls. The blue greenish water, the soft gurgling sound, the cool waters gushing from the hills to the plains makes a sight that cannot be easily forgotten. The fact that all the seven waterfalls fall together magnify the beauty of the place. Water sports and rafting are common here. One of the falls is known as the Khoudong waterfall.
