Lampson Falls, the most popular waterfall in St. Lawrence County, is easily accessed at the Degrasse State Forest on Route 38. An impressive falls at an estimated 40 feet tall and 100 feet wide. Lampson is a shallow and broad-faced falls, which can have huge amounts of water flowing over it during peak melt season in the spring. During the summer it calms and becomes a much quieter setting. At the bottom of the falls a small beach has formed allowing for swimming and picnicking. The 15 minute walk into this area is well worth it.
