Mount Desert Island loop

The full Mount Desert Island loop, at approximately 144 km (90 miles) with over 1,900 meters (6,200 feet) of elevation gain, is considered a difficult road ride requiring very good fitness. While the paved Park Loop Road offers smooth asphalt, it includes significant climbs. Some segments of the longer loop might even be unpaved and challenging, potentially requiring you to push your bike.

The loop primarily features paved roads, notably the Park Loop Road, which is generally smooth with moderate grades. However, the full 144 km route can include varied terrain, with some sections potentially being unpaved. For a different experience, Acadia National Park also offers 45 miles of historic crushed rock carriage roads, which are car-free and suitable for bikes with wider tires, featuring both flat sections and rolling hills.

The loop offers breathtaking coastal views and passes by several iconic landmarks. You'll encounter the historic Bass Harbor Light Station, scenic Seawall Road, and beautiful lakes like Echo Lake, Beaver Dam Pond, Jordan Pond, and Eagle Lake. You'll also experience the stunning coastal views at Otter Cove and pass through Bar Harbor Main Street. Don't miss the panoramic views of Bar Harbor and Mount Desert Island from Cadillac Mountain.

This challenging 144 km (90 mile) road cycling loop typically takes around 7 hours to complete, not including stops. Given its difficulty and significant elevation gain, plan for a full day or even multiple days if you wish to explore the many attractions along the way.

The best time to cycle is generally spring, summer, and fall. Summer (July and August) offers warm weather but can be very crowded, especially on the Park Loop Road. Spring and fall offer cooler temperatures and fewer crowds, with fall providing spectacular foliage. Riding early in the morning, regardless of the season, can help avoid congestion.

Given the length and difficulty of this loop, essential gear includes a well-maintained road bike, appropriate cycling attire, a helmet, plenty of water, energy snacks, a repair kit (spare tube, pump, tire levers), and navigation tools. Layers of clothing are advisable due to changing coastal weather. Don't forget sunscreen, sunglasses, and a camera for the stunning views.
