The Presumpscot River Preserve, with trails maintained by Portland Trails, consists of 48 acres along the Presumpscot River, which flows from Sebago Lake to Casco Bay, owned collaboratively between the City of Portland, City of Falmouth, Portland Trails and private landowners. This Preserve is accessible from trailheads at Oat Nuts Park on Summit, Hope Lane, Overset Rd, and the west side of Rte 100 at the bridge over the Presumpscot (Portland/Falmouth line).
From the Route 100 Trailhead, it is approximately 2.2 miles one-way to the Oat Nuts trailhead on Summit, and 1.6 miles to Presumpscot Falls. This makes for a 4.4 mile or 3.2 mile total out and back. A lollipop loop is possible, using the Sebago To The Sea Trail, but requires travel on roads (Garsoe Drive and Route 100). For comprehensive maps, see Portland Trails’ site.
This small riverside preserve is an excellent place to bike, to run trails, to see birds and wildflowers, to fish, and even (for the bold) to swim. Spring wildflowers cycle through their peak here, including trillium, trout lilies, and lady slippers, and every week can include a new bloom.
On recent trips, we saw cormorants, herons, ospreys, nuthatches, gulls, and sparrows. Some of these birds are drawn by late spring’s alewife run. In mid-summer, there are blackberries along the Oat Nuts trail, and in open areas near power lines, closer to the Overset entrance.
Portions of the Oat Nuts trail have poison ivy close to (but not on) the trail, so be cautious about small children wandering and grabbing. Additionally, you will find mosquitoes aplenty during the wetter months, which are not terrible if you keep moving.
The falls are loud, rushing, and impressive, particularly in the spring melt, and the trail continues alongside, showing the former dam site, which was removed in 2002. The trail ends at private land prior to the Allen Ave/Falmouth bridge, so please respect private property.
The Presumpscot River Preserve is a family-friendly destination, with shaded trails and loops of wildflowers to explore, close to Maine’s largest downtown, but far from a city. We have a particular affinity for this place, having visited as a family, and have smelled wildflowers, picked berries, and inspected salamanders and bugs underneath logs there for years.
