Mt. Grant Summit Loop

FEATURED WALK

Length: 2.1 miles
Estimated Time: 1 hour
Difficulty: Moderate
Type: Loop
Submitted by: Alicia McVey

This just-over-2-mile loop showcases some of the island’s most peaceful forest trails, with mossy woods, ancient Douglas firs, and sweeping summit views in every direction. From Mount Baker to Vancouver Island, the vistas are well worth the climb. The preserve is bordered by private land, so please stay on designated trails and do not stray off preserve property.

The route is steep in places, especially on the way up, but the trails are well-marked, and a gentle, winding descent makes for a rewarding return.

Parking Options and Trailhead

After turning off West Valley Road, you’ll immediately pass the lower parking lot on your left (via Richard Lee Lane). If you’d like to add a little extra elevation to your hike, park here and walk up the paved road to the main trailhead. Otherwise, continue driving up the hill to the upper lot, where you’ll find the main trailhead, plenty of parking, and a portable restroom. Start your hike at the trailhead sign and enter the forested trail.
