Hiking Mont Sutton (2026): Trails, Round Top Loop & Eastern Townships Guide

Mont Sutton sits in the heart of the Eastern Townships about an hour from Montreal, offering over 80 km of marked hiking trails through dense Appalachian forest. It’s a quieter and wilder alternative to Mont-Saint-Hilaire and Mont-Royal — and one of the best places in Quebec for fall colours. Here’s the complete 2026 hiking guide.

Why Mont Sutton

The mountain is a four-season resort but the trail network — managed by Les Sentiers de l’Estrie and Sutton Mountain — is free outside ski season. The terrain is real: rocky outcrops, summit panoramas across the Townships, mixed maple and birch forest. In late September and October, the foliage rivals Vermont.

How to Get There

By car: Highway 10 East to exit 68 (Cowansville), then Route 139 South to Sutton. About 1 hour 15 minutes from downtown Montreal.
Parking: Multiple trailhead lots at the mountain base. Some are free, the ski-station lot has a small day fee in fall.
No direct transit.

Top Trail Options

Round Top Loop (12 km): The classic circuit to the summit. Rocky, scenic. 4–5 hours.
L’Altitude 600 (5 km): Shorter loop with two viewpoints. ~2.5 hours.
Sentier de l’Estrie section: Connects to the long-distance Eastern Townships trail.
Sutton Village + Lake (easy): Flat 4 km walk for non-hikers.

Best Season

September 25 to October 15 is the best fall colour window. Late May–June is peaceful and lush. July–August can be hot and humid — start early.

Practical Information

Trail access: ~$10 day pass at trailhead in fall, free in summer outside ski season.
Facilities: Welcome chalet, washrooms, drinking water, on-mountain café in season.
Dogs: Allowed on leash on most trails.
Cell service: Patchy on the back slopes — download offline maps.
