Ladder Trail

What makes it special

This steep, engineered route rockets up the east face of Dorr Mountain using long runs of stone steps, iron rungs, and a few short ladders. It’s strenuous and hands-on, but generally less exposed than the park’s famous cliff routes, making it a great next step if you want an iron-rung challenge without the full vertigo factor.

Route, distance, and what to expect

The most popular outing is a loop of about 3.5 miles total: climb the Ladder Trail, connect via the Schiff Path to Dorr’s summit, then descend the Dorr South Ridge Trail back toward your start. Expect roughly 1,100–1,150 feet of gain, sustained steepness, and sections where you’ll use both hands. Surfaces are classic Acadia granite—stone stairs, slabs, and boulders—with several iron aids through narrow breaks in the cliffs.

Scenery and feel

Early forest gives way to open granite and expanding views over the valley and The Tarn below, with broader panoramas higher up and from the summit. You’ll see the best of Acadia’s trail craftsmanship—tight switch stairways set into bedrock and well-placed ironwork that keeps things fun without being outrageous.

Difficulty and who will (and won’t) enjoy it

This is a demanding hike for fit hikers comfortable with heights and ladders. It’s not appropriate for small children, anyone uneasy with exposure, or folks with mobility limitations. Dogs are not allowed on this ladder/iron-rung route.

Access and logistics

Trail access is from the east side of Dorr Mountain above The Tarn. Park along the gravel roadside pull-offs just south of The Tarn on Route 3, south of the Sieur de Monts entrance. No special permit is required, but an Acadia National Park entrance pass is.

Tips and tricks

• Go up the Ladder Trail, not down. The rungs and steep steps are far friendlier in ascent.
• Keep your hands free (small pack, no handhelds) and wear shoes with real grip; granite is slick when damp.
• Start early to beat crowds and have the ladders to yourself. If you want to extend, you can traverse to other routes on Dorr or continue the ridge toward Cadillac for a bigger day.

Best time to hike

April through October is prime. Spring through fall offers the best conditions; autumn adds standout foliage. Avoid wet or icy days—granite and iron get treacherous—and most hikers should skip winter conditions here.
