Due to the extensive regulation of the nearby lakes such as Langavatnet and Nybuvatnet in the mountains above this lake, several of the large waterfalls that once fed Ringedalsvatnet are no longer regularly flowing. The Tyssestrengene and Ringedalsfossen waterfalls were once very notable waterfalls on the cliffs surrounding this lake. The Trolltunga cliff overlooks this lake too, attracting many tourists and hikers each year.
