A printed Waterfalls Guide for St. Lawrence County is available, with an electronic version available here, or you can print out the information from this website. We also have an interactive trail map to help you plan your hikes. Have fun discovering and you’ll understand why we say “Naturally Fun(!) St. Lawrence County.”

Exploring Our Majestic Waterfalls

The rivers of St. Lawrence County have long since been part of the life of the North Country. Villages were built on shores for water supply, food and power. Old mill sites can be found at both Twin and Harper Falls where only their foundations and the rock walls formed to channel the water past the mill wheel remain. Many of the mills were among the largest in New York. With the shift of the population away from the falls, much of the land has been purchased by the State, allowing easy and public access to the majority of the falls in St. Lawrence County.

Each waterfall in the county has its own "personality". If you visit the Tooley Pond Road section of the South Branch of the Grasse River you will understand waterfall personality. There are six major waterfalls, all completely different in form as a response to erosion of the unique geology of St. Lawrence County. During the last glacial period, 15,000 years ago, the county was beneath a two-mile thick sheet of ice. After the glaciers receded and top soils were deposited, rivers formed new channels flowing over rock ledges, creating the waterfalls of today.

A Few of Our Favorite Falls to Discover ...


Harper Falls

Harper Falls is on the North Branch of the Grasse River. The hike into this area is almost as beautiful as the falls itself.

From the intersection to the trail parking is ½ mile on the Donnerville Road which is dirt and gravel and is shared with ATV users, so please use caution as there are several blind hills and turns. Starting from Donnerville Road and walking up the river toward Harper Falls offers a relaxing trek, with a couple of hills and small creek crossings.

Once at the falls do not only observe them from a distance, take a walk to the top for that "up close feeling". While walking up you may notice the path has stone walls along the edge. These are the remnants of an old sawmill. This mill was made during the time the town of Donnerville was active and running.

There is an alternate hike as well for Harper Falls, which is from the opposite end of Donnerville Road, which intersects with County Route 24. The drive in is about 1.75 miles. This hike is about 2 miles to the falls. There is also the remnants of an old cemetery on this end of Donnerville Road.



Lampson Falls

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.

The access for Lampson Falls is the Grasse River Recreation Area on Route 27 in Clare, just north of Degrasse. Look for the brown and yellow DEC sign at a gated road. Park on the road side and head down the dirt road.


Stone Valley

The trail in Stone Valley is one of the most popular nature walks in the North Country. Following the shores of the Raquette River through Colton, the scenery is amazing. There are a series of waterfalls that continue for a mile or more along the trail, which extends for two or more miles. During the spring, the power of the highwater from the snow melt in the Adirondacks is impressive. In winter months expect the beginning of the trail to slippery and use caution when walking along the river.

The River offers experienced kayakers a challenge and canoeists should not consider padding this section of the river. There are a series of signs along the path describing some of the geological features of the area. To the geologists this is a unique area, the connection of the Adirondack Mountains and the St. Lawrence Lowlands. Watch for the signs posted on the trees to learn more.

From Route 68, turn left on to Route 56 in Colton. At the Hepburn Library, turn right. There ae two access points to the trails, one before the bridge near the Colton Historical Society, and one across the bridge near the Colton Fire Department.

If you are coming from Route 56 north, take a left at the Hepburn Library.

Tooley Pond

The land along Tooley Pond Road is the Northern River Flow-Tooley Pond Tract, which is a section of the New York DEC public lands, allowing access to this simply amazing place. A 16-mile section of the South Branch of the Grasse River meanders within the tract. Along this stretch, six major waterfalls exist with a variety of named rapids. The falls include: Rainbow Falls, Bulkhead Falls, Flat Rock Falls, Twin Falls, Sinclair Falls and Basford Falls. They range from the 40 foot drop of Rainbow Falls to the gentle sloped falls at Sinclair Falls, a perfect place to have lunch. The South Branch of the Grasse has excellent kayaking and canoeing with easy carries around the falls, if you do not desire to take the express route. There is good fishing in the area, but check for special regulations on the South Branch of the Grasse River. There is also an enjoyable hike up Tooley Pond Mountain at the southern end of the road.

Little exploration of the area had taken place until the 1860s when iron was discovered in the region. In 1866 the town of Clarksboro was established near Twin Falls on the shore of the Grasse River. An iron furnace and water-run sawmill were built to support the town. The foundation of the sawmill can still be seen at the top of Twin Falls. This is one of the only artifacts left of the town of Clarksboro. Iron was mined in this region until the 1950s when the mines closed because of low iron prices. Exploring this area can reveal the unique history of the County and show some of the best hidden waters.
