Trail description

Mileposts 0.0 - 2.2

The Triangle Trail begins at the Ramapo-Dunderberg Trail, 75 yards from Grove Drive. After a 1/2 mile, the telephone line starts running along with a telephone line. The trail then turns on a woods road and turns left towards Black Ash Brook. The Triangle Trail turns right and follows the former path of the Ramapo-Dunderberg Trail. It goes uphill gently and at milepost 1.25, crosses Deep Hollow Brook. As the TrT goes north, Black Ash Mountain is visible from the right. At 1.7 miles, the TrT goes through the old Park boundary on Fox Mountain.

Mileposts 2.21 - 4.4

After crossing a fairly level region, the Triangle Trail crosses a stream at 2.5 miles and joins up with the White Bar Trail from the left. Soon the TrT leaves the White Bar and climbs Parker Cabin Mountain. The Triangle Trail joins the Ramapo-Dunderberg Trail and comes to the location of an old fire tower. The Triangle Trail leaves the R-D Trail and goes to the eastern edge of Lake Sebago. The trail goes downward slowly, then more gradually as the trail progress. At 4.1 miles, the Triangle Trail meets up with the Victory Trail near Lake Skenonto. Soon afterward, the Triangle Trail crosses a brook at 4.2 miles.

Mileposts 4.41 - 5.25

The Triangle Trail continues on after passing a brook at 4.2 miles, the trail goes over several ridges and comes near an arm of Lake Sebago. It joins the unmarked Sloatsburg Trail, which brings it along the western edge of the lake. At 5.2 miles, a person repainted all of the blazes of the Old Rectangle Trail, which were white. In another 250 feet, the Triangle Trail comes to an end at the White Bar Trail near the Dutch Doctor Shelter.


The Triangle Trail was blazed in 1939 by the famous Kerson Nurian as the Yellow Bar Trail. It started from the Black Ash Brook, where the Ramapo-Dunderberg Trail used to go on. Nurian used existing roads to make his trail, ending at Parker Cabin Mountain. Nurian sold his trail to the NY-NJ Trail Conference and left for Bulgaria in 1943. While Nurian was in Bulgaria, metal yellow triangles were added, 80 of them to be exact. In 1947, Nurian returned from Bulgaria. In September 1947, the 80 trail markers had been removed. Once it became clear who removed them, the triangles had been repainted on trees. After discussions with Joseph Bartha and the Conference, they had Nurian leave the trail alone on the condition that painted triangles were used instead of metal ones.
