The Arden-Surebridge Trail is a marked trail in Harriman State Park. It is 4.95 miles long and blazed an upside-down red triangle on white. The trail crosses many trails, but spends most of its time jointed with the Long Path and some with the Appalachian Trail. The trail was blazed in Summer 1921 by J. Ashton Allis. Notable places along the route are Lemon Squeezer, a notable rock formation and Elk's Pen, a meadow.

The Arden-Surebridge Trail begins at the park enterance on Route 17. The trail follows Arden Valley Road for .85 of a mile. About 350 feet from the Elk's Pen Parking Area, the Appalachian Trail leaves to the right and the A-SB Trail continues on down a paved road. The trail turns right and goes up an old woods road. The trail goes uphill and at 1.25 miles, the A-SB Trail crosses the paved road. The trail goes on to cross Island Pond's outlet stream and the paved road once again. Then the trail begins to climb again and crosses the "Crooked Road", the old Park Boundary until 1927. The A-SB Trail starts climbing the steep ledges of Island Pond Mountain. At the top is a magnificent view of the lake and the trail continues on. The A-SB Trail climbs again, this time, steeply up to the summit. At 1.85 miles, the Appalachian Trail and A-SB Trail join together. In 3/10 of a mile, the two trails come to the strange rock formation called Lemon Squeezer. Just before entering this rock, the two trails split. The Appalachian Trail goes through Lemon Squeezer and the A-SB Trail goes to the right of it. At 2.4 miles, the Long Path joins together and marks the beginning of the White Bar Trail. At 2.45, the trails turn right while the Bottle Cap Trail continues straight ahead.
Mileposts 2.46 - 4.95
The Arden-Surebridge Trail/Long Path joint continues on after the Bottle Cap Trail and begins climbing steeply. At 2.7 miles, the Lichen Trail begins to the right and the A-SB/LP joint goes through laurels and rhododendrons. The trails climb a mountain then descends, climbs again and descends once more. At 3.25 miles, the trails come upon Times Square, an intersection of three trails, the Long Path, Arden-Surebridge and Ramapo-Dunderberg Trails. In 75 feet, the Long Path leaves to the right and the A-SB Trail continues on. The A-SB Trail crosses a brook and reaches the start of the Dunning Trail at 3.7 miles. The trail bears right, leaving the wide Surebridge Mine Road and drops gradually down a bank. After passing a swamp and a mountain, the A-SB junctions with the Red Cross Trail at 4.7 miles. 1/4 of a mile later, the trail ends at the parking area for Lake Skannatati.
