The Peter Desrochers Memorial Country Knolls Trails are located in the Town of Clifton Park. The ~3.5-mile trail system is named in honor of the late Peter B. Roschers and it is under the jurisdiction of the Longkill Park District #1.
A small trailhead parking area is located along the east side of Burning Bush Boulevard just south of Thunderbird Drive; this access point enters onto the Eastwood Trail, which is in the southwest portion of the trail system.
Additional access points to the trail system include:
- From the west side of Terrace Court (either of two entrances onto the Tanglewood Loop Trail (south end of loop or north end of loop), which is in the northwest portion of the trail system);
- From the east side of Terrace Court (onto the Knolls Hollow Brook Trail (west end), which follows along the northern edge of the trail system);
- From the south side of Wood Dale Drive (onto Knolls Hollow Brook Trail (east end), which follows along the northern edge of the trail system);
- From the west side of Sweet Brier Drive (onto South Branch Trail, which is in the eastern end of the trail system);
- From the east side of Knollwood Drive (onto Sweetbrier Trail, which is in the southeastern portion of the trail system); and
- From the north side of Ushers Road (into the south side of the trail system).

During one of my visits to this trail system (and further upstream along the Terrace Hollow Connector Trail), I observed a native brook trout in this tiny stream! Read more about New York’s official state fish.
