Overview
About This Trail
The Dorr Mountain South Ridge Loop runs about 3.2 miles round-trip with roughly 1,100–1,270 feet of gain. It relies on the Ladder Trail and Schiff Path in places, featuring granite steps, iron rungs, ladders, and boulder fields. It’s a true lung-buster that rewards focus with a high-adrenergic ridge and coastal vistas at the summit. Enter prepared: strong boots, water, and a plan for the ascent and descent.
Highlights
Strenuous - advanced difficulty (Ladder Trail section)
Summit with panoramic coastal views over Mount Desert Island, Frenchman Bay, and the Atlantic; dramatic granite ridge with exposed sections

What Hikers Say
The climb demands focus and grit; the ladder sections punch above their weight, and exposure is real on the ridge. Weekends can feel crowded, but the payoff is a broad coastal panorama and a sense of accomplishment that sticks with you.
