If beginning at Bear Mountain Bridge, there is typically roadside parking available, though it can become quite busy on the weekends. The AT enters the forest a few hundred feet up the road heading northeast, but an alternate access trail leads straight to Anthony's Nose, a popular overlook with an excellent vantage point to Hudson River.

Before the first road crossing, you'll reach the first campsite along the stretch. A few miles north, you'll reach US-9. A small gas station and market sit at the intersection and are often used for resupply.

Continuing north, the trail crosses several roads and meanders its way through small communities. Clarence Fahnestock State Park lies ahead and welcomes you with a few small lakes, and ultimately Canopus Lake. The trail parallels the west shore of the lake then continues north where it crosses the Taconic State Parkway. No parking area or services exist here or where the trail crosses I-84. Ahead, the trail passes another shelter, then Depot Hill before crossing NY-55.

The final portion of this segment holds two final landmarks. Several stories surround Nuclear Lake, as it was once home to a private nuclear research facility. The lake was also the site of a plutonium spill prior to its purchase by the NPS. Though picturesque and littered with wildlife, no swimming is allowed.

Atop West Mountain, the trail reaches the final overlook of this segment, commonly known as Cat Rocks. Its picturesque vantage point makes it a perfect opportunity for a day hike.

At NY-22, you'll reach the Appalachian Trail Station and a parking area just north on the road.
