Overview
Park Loop Road is a scenic road through part of Acadia National Park in Maine, United States. 27 miles (43 km) long, it traverses the eastern side of Mount Desert Island in a (mostly) one-way, clockwise direction, from Bar Harbor to Seal Harbor. (The road is two-way for a section between Wildwood Stables, toward the middle of Mount Desert Island, and the Hulls Cove entrance near Bar Harbor, to the north.) A toll is required for vehicles continuing on the Loop Road beyond the entrance station immediately inland from Schooner Head overlook; the 5.3-mile (8.5 km) section between Paradise Hill Road, at the foot of Cadillac Mountain, and the entrance station is toll-free.
Practical Info
Suggested Duration2-4 hours
Best TimeMid-September to mid-October transforms this 27-mile scenic drive into a breathtaking tunnel of gold, amber, and crimson foliage. To avoid heavy traffic, enter the loop before 7:00 AM or after 4:00 PM. These off-peak hours provide optimal soft, low-angle sunlight for photographing the dramatic intersection of rocky cliffs and coastal forests.
Getting ThereThe road is primarily a one-way, two-lane scenic loop driven in a clockwise direction, typically accessed from the Hulls Cove Visitor Center. The right-hand lane allows for parallel parking in designated sections. Non-drivers can easily board the Island Explorer Route 4 (Ocean Drive Bus) from Bar Harbor, which stops sequentially at major landmarks along the loop.
Travel Tips
- The 27-mile scenic spine enforces a strict one-way rule from Sand Beach to Otter Cliff; missing a specific overlook kiosk layout requires driving the entire multi-mile loop to return, as reversing or driving against the traffic flow is strictly illegal and subject to immediate arrest.
- Right-lane parking along the loop requires fully folding in mirrors to avoid side-swipe damage from park transit buses; from March to mid-August, federal laws protecting nesting peregrine falcons force absolute closures of Precipice Trail and its trailhead parking lot.
- Historic stone overpasses along the loop bottleneck clearance heights at a low 11'8", completely banning high-profile Class A RVs and roof-box campers from specific sectors; the loop road undergoes complete winterization closure from December 1 to April 14 annually.
Reviews
Positive
- The 27-mile scenic drive beautifully strings together mountains, cliffs, wild forests, and North Atlantic seascapes, delivering top-tier driving visuals.
- The asphalt surface is smoothly paved, with clear traffic signage along the route; virtually every scenic pull-off packs neat picnic spots and trash bins.
- The split one-way lane rule effectively prevents narrow mountain head-on clogs; entry booths filter cars fast, and key curves feature heavy safety barriers.
- Buying a single 7-day vehicle pass grants unlimited cruising on one of America's premier scenic drives, offering unquestionable value for money.
Heads up
- During the traditional October autumn foliage peaks, the road degenerates into a massive mobile parking lot, destroying any sense of wild tranquility.
- Because much of the loop allows curbside parking on the right lane, a single rookie backing into a tight spot can completely paralyze the entire highway flow.
- Cell service along the route is patchy with complete mountainside dead zones; tourists relying on online maps can easily miss pull-offs and be forced around the whole loop.
- Outside of the main base camps, the long scenic highway completely lacks gas stations, EV chargers, and dining stops; you must power up before entry.
