Wetumpka Falls is a moderately large, but seldom-known waterfall in Warren Township. The waterfall cascades down a gap in the first Watchung Mountain, and is characteristic of many other waterfalls in the Watchung Mountains, such as Hemlock Falls or Hobble Falls. The waterfall is located directly off of Somerset Street and across the street from the town courthouse.

The waterfall is visible from a bench located along the road. Additionally, there is an unmarked and unofficial trail down to the base of the falls.
