Bear Mountain in Salisbury, Connecticut, rises to 2,316 feet as the highest summit in the state, and the Undermountain Trail provides the most direct hiking approach to its rocky, fully exposed peak in the Taconic Range of Litchfield County. The trailhead parking area is on Route 41 south of Salisbury village; parking is free and no permit is required. The route follows the yellow-blazed Undermountain Trail for 2.8 miles through mixed hardwood and northern boreal forest before joining the white-blazed Appalachian Trail for the final ridge traverse to the summit cairn, totaling approximately 7.2 miles round trip with roughly 1,800 feet of cumulative elevation gain. The ascent is sustained and demanding. Lower sections of the Undermountain Trail are packed dirt and rocky forest path through oak and birch; the upper trail transitions to exposed quartzite ledge with sections of Class 2 boulder scrambling requiring use of hands. The summit is fully above the treeline, offering a 360-degree panorama across the Taconic Range to the west into New York State, south along the Connecticut traprock ridge, and north into the Berkshire Hills of Massachusetts. Afternoon thunderstorms develop rapidly over the exposed peak from June through August; early morning starts — before 8 AM — are strongly advisable during these months. No water sources should be relied upon on the upper half of the route; carrying at least three liters from the trailhead is essential. The Connecticut section of the Appalachian Trail passes through this area, and the Bear Mountain summit is a notable waypoint for AT through-hikers. Microspikes or crampons are required from late November through April, when snow and ice persist on the north-facing upper slopes and the quartzite ledge becomes treacherous.
