Mansell Mountain South Ridge Trail

Why hike it

On Acadia’s quieter west side, the South Ridge of Mansell delivers a classic mix of shady forest, rugged granite, and sweeping looks over Long Pond and Southwest Harbor—without the east-side crowds. It’s moderate overall, with a few short, steep bits that keep it interesting, and plenty of open ledge for snack breaks and lingering.

Route and length

From Gilley Field at the end of Mill Field Road, the South Ridge climbs steadily through spruce–pine–birch forest onto broad, grippy granite ledges and occasional boulder fields. Expect a few steeper pitches and stone steps near the top. The South Ridge segment is about 2.5 miles one way to the summit; an out-and-back runs roughly 5 miles total. Many hikers stitch shorter loops using nearby trails (Razorback, Perpendicular, Western Mountain Connector); those sampler loops commonly come in around 2–2.5 miles total. Blue blazes and signed junctions mark the way, but the web of trails means a map/GPS helps.

The experience

You’ll trade constant ocean panoramas for a more varied, woodsy ridge walk that opens onto big vantages of Long Pond and the forested hills around Southwest Harbor. The open granite offers great lounging and picnic spots, and the whole area tends to be peaceful compared to Acadia’s marquee peaks.

Best time to go

Spring through late fall is prime, with the sweet spot from May–October for clear views and comfortable temps. Summer brings lush vegetation (and bugs—pack spray). Fall foliage is excellent and crowds thin out. In winter, expect ice or snow; traction aids are often necessary, and navigation is trickier on ledge.

Logistics and tips

• Parking at Gilley Field is limited—arrive early in summer.
• Footing is rocky and uneven; sturdy shoes are a must. Ledges get slick when wet.
• Carry layers: it can be breezy on exposed granite even on warm days.
• There’s no potable water—bring what you need.
• Leashed dogs are allowed on South Ridge. If you loop, note that Perpendicular Trail is a ladder/step route where pets aren’t allowed.

Need-to-know

Difficulty lands squarely in the moderate zone for most hikers, including active kids and older adults. The elevation gain is roughly 950 feet, and while junctions are signed, the interlacing trail network can confuse the unprepared—keep a map handy.
