Mount Nonotuck

Mount Nonotuck is a summit that rises 827 feet above the Connecticut River Valley, featuring steep basalt cliffs wrapped in dense forest. The dark rock formations create a striking prominence in the landscape and form a distinct ridge line against the sky.

A hotel called the Eyrie House operated on the mountain from 1861 until 1901, making it a destination for visitors in the 1800s. The building was destroyed by fire during an unusual incident involving the attempted cremation of horses.

Local tribes valued this summit as a lookout point and resource site along the river corridor for generations. The steep rock faces and forested slopes remain defining features that connect visitors to how people once used these heights.

The route to the summit follows the Metacomet-Monadnock Trail, a marked hiking path that climbs through forested slopes and rocky sections. Good footwear and care near the steeper cliff edges are necessary for a safe visit.

The basalt rock composition creates distinct microclimates at different elevations and slope angles on the mountain. These conditions allow plant species to grow here that are found rarely or not at all elsewhere in the state.
