Most hikers want to climb Mt. Tammany in New Jersey (above), but the best view of Mt. Tammany is from the top of the other gatepost of the Gap, Mt. Minsi in Pennsylvania.
From Dunnfield Creek parking area (Worthington State Forest) to the top of Mt. Tammany via the Red Dot Trail is a steep and rocky 1.5 mile climb.
From Dunnfield Creek parking area (Worthington State Forest) to the top of Mt. Tammany via the Blue Blazed Trail is a more gradual 2.5 mile climb, most of it on wide trails and old roadbeds.
The Red Dot and the Blue Blazed (or Blue Dot) trails join at the top of Mt. Tammany to form a 4-mile loop.
Also atop Mt. Tammany is the Mt Tammany Fire Road, which runs along the ridge to meet the Turquoise Trail to Sunfish Pond. This is one way to hike both Mt. Tammany and Sunfish Pond without backtracking.
For brief descriptions of all these trails, see the park's bulletin on Hiking the Gap at right (pdf file).
