The Marilla Springs Trail follows Marilla Brook 3.5 miles from where it empties into Marilla Reservoir up to the headwaters near the Stickney area of the Allegheny National Forest. This is the farthest western point of the Tuna Valley watershed. With all the attributes most hikers appreciate in a woods walk, the Springs Trail is seeing increased traffic as more walkers spread the word. With easy access from the reservoir, the lower section of the trail is especially gaining fans. Most walkers stroll over the Marilla Bridges Trail to Madeline's Birders' Rest gazebo and hike as far as time and energy allows, then retrace their route back to the reservoir.
To find the Marilla Springs upper trailhead, drive west on Rt. 346 (West Washington St.) to Stickney Rd. just before The Willows restaurant. Make a left and drive up Stickney Rd. Look at your odometer when the road becomes Forestry Road 173 as the road surface changes from asphalt to dirt. On the left 3.1 miles from the end of the asphalt is Forestry Road 173H. Walk around a locked forestry gate that excludes unauthorized motorized vehicles. Keep walking about .5 miles until a sign on the left designates the upper trailhead for the Marilla Springs Trail. The trek is mostly downhill, though never steep (great for X-country skiing). After strolling 3.5 miles along Marilla Brook, Madeline's Birders' Rest gazebo on the Marilla Bridges Trail is a favorite resting spot.
Access to the White Pine Trail loop is .6 m up the Springs Trail. For more ambitious hikers, the upper end of the Springs Trail connects to the Allegheny National Forest on Forestry Road 173 and eventually to the North Country Trail.
