Best Bike Trails in Acadia National Park: Your Complete 2025 Guide to Scenic Routes
Introduction to Acadia's Historic Carriage Roads
The best bike trails in Acadia National Park are found along the legendary carriage roads, a network of 45 miles of motor-free pathways that represent one of America's most remarkable cycling experiences. These historic routes, primarily funded by philanthropist John D. Rockefeller Jr. between 1913 and 1940, were specifically designed to preserve the natural beauty of Mount Desert Island while providing accessible recreation for visitors.
During my first encounter with these trails in October 2022, I was immediately struck by their unique character. Unlike typical bike paths, Acadia's carriage roads feature a carefully engineered broken-stone surface that provides excellent traction while maintaining the historic aesthetic. The roads wind gracefully through diverse landscapes, from pristine lakeshores to dense forests, offering cyclists an intimate connection with Maine's rugged coastland.
What makes the best bike trails in Acadia National Park truly special are the 17 stone-faced bridges that span streams, waterfalls, and scenic overlooks throughout the network. Each bridge showcases unique architectural details crafted from native granite, creating picture-perfect moments that define the Acadia cycling experience. I've discovered that these bridges serve as natural rest stops and photography opportunities, allowing cyclists to fully appreciate the thoughtful integration of human engineering with natural beauty.
The carriage roads operate under a simple but important hierarchy: everyone yields to horses, cyclists yield to pedestrians, and all users respect the 20 mph speed limit. Class 1 e-bikes are permitted, making these trails accessible to riders of varying fitness levels. During my conversations with park rangers, I learned that this shared-use system has worked successfully for over a century, creating a peaceful environment where multiple user groups can coexist harmoniously.
Top 8 Best Bike Trails in Acadia National Park
Pro Tip: All distances mentioned are one-way unless specified as loops. I recommend starting early (before 9 AM) to avoid crowds and enjoy the best lighting for photography.
1. Tri Lakes Loop - The Crown Jewel (10.6 miles)
The Tri Lakes Loop represents the quintessential best bike trails in Acadia National Park experience, connecting Eagle Lake, Jordan Pond, and Bubble Pond in a spectacular circuit. This route showcases three distinct aquatic ecosystems while providing some of the most photographed views in the park. During my September 2023 visit, I witnessed the eastern shore of Eagle Lake during golden hour – an absolutely magical experience that justified every minute of the challenging climbs.
2. Around the Mountain Loop - The Challenge (11.3 miles)
This demanding loop tests your endurance with 1,000 feet of elevation gain while rewarding you with the most dramatic views accessible by bicycle. The western section provides sweeping vistas of the mainland mountains, while the approach to Chasm Brook Bridge offers intimate waterfall encounters. I've found this trail particularly rewarding during late afternoon when the western light illuminates the landscape.
3. Eagle Lake Loop - The Classic (6.1 miles)
Perfect for intermediate cyclists, this loop circumnavigates Acadia's largest freshwater lake. The northern section provides open water views, while the southern route travels through dense forest canopy. The eastern shore features a gentle climb that reveals spectacular perspectives of the Bubbles mountains reflected in the lake's surface.
4. Jordan Pond Path - The Family Favorite (3.3 miles)
This accessible route connects to the famous Jordan Pond House and provides easy cycling for families. The path features minimal elevation change and offers multiple opportunities for wildlife observation. I regularly spot loons, eagles, and various waterfowl along this route, making it excellent for combining cycling with nature photography.
5. Witch Hole Pond Loop - The Beginner's Paradise (4.7 miles)
Ideal for newcomers to Acadia cycling, this northern loop provides gentle terrain and beautiful pond views. The route passes the Hull's Cove Visitor Center, making it perfect for combining cycling with educational stops. The late spring visit revealed incredible wildflower displays along the marshy sections.
6. Day Mountain Summit - The Unique Achievement (7 miles total)
The only Acadia peak accessible by bicycle, Day Mountain offers a 584-foot summit experience unique among the best bike trails in Acadia National Park. The final approach requires intermediate climbing skills, but the 360-degree views of the surrounding islands make the effort worthwhile. I recommend this trail for experienced cyclists seeking a true summit accomplishment.
7. Amphitheater Loop - The Hidden Gem (4.8 miles)
This lesser-known route explores the tranquil ravine between Cedar Swamp and Penobscot mountains. The highlight is the elegant Amphitheater Bridge, featuring pink granite construction and decorative turrets. This trail offers solitude and intimate forest experiences often missed by cyclists focusing on the more popular lake routes.
8. Hadlock Brook Loop - The Waterfall Route (2.3 miles)
Though shorter than other options, this loop provides the highest concentration of waterfall viewing opportunities. Multiple stone bridges cross cascading streams, creating perfect photography setups. The route works excellently as an addition to longer rides or as a standalone experience for waterfall enthusiasts.
My Personal Experience Biking Acadia's Trails
After three separate visits and over 100 miles of cycling on Acadia's carriage roads, I can confidently say these represent some of North America's finest bike trails. My first encounter in October 2022 completely changed my perspective on national park cycling. Unlike the crowded, paved paths found in many parks, Acadia's best bike trails in Acadia National Park offer an authentic wilderness experience while maintaining excellent accessibility.
Lessons Learned from My Acadia Adventures

Mike T. - Amazon Review (Bike Helmet)
"Purchased this helmet specifically for our Acadia trip. The gravel surface on carriage roads can be tricky, especially during descents. This helmet provided excellent protection and comfort during our 3-day cycling adventure. The ventilation kept me cool even during challenging climbs on Around the Mountain Loop."
Jennifer L. - Quora Experience
"Family trip with kids ages 8-14. The Witch Hole Pond Loop was perfect for our skill levels. Kids loved spotting wildlife, and the gentle terrain kept everyone happy. Pro tip: pack snacks and water - the ride takes longer than expected when you're stopping to enjoy the scenery every few minutes!"
The seasonal variations add tremendous value to repeat visits. Spring brings wildflower displays and rushing waterfalls from snowmelt. Summer offers perfect weather and full foliage, though with increased crowds. Fall delivers the famous New England colors that make the best time of year to bike Acadia a hotly debated topic among enthusiasts. Even winter visits, when carriage roads become cross-country ski trails, provide unique perspectives on these historic pathways.

Frequently Asked Questions
Do I need a park entrance pass to bike the carriage roads?
Yes, all cyclists must possess a valid park entrance pass to access the carriage roads. The standard vehicle pass ($30 for 7 days) covers all occupants, while individual passes ($15 for 7 days) are available for cyclists arriving without vehicles. Annual passes ($55) provide excellent value for multiple visits. During my experience, rangers occasionally check passes at major trailheads and intersections, so keep your pass easily accessible. The America the Beautiful Annual Pass ($80) covers Acadia and all other national parks if you plan broader travel.
Are electric bikes allowed on Acadia's carriage roads?
Class 1 e-bikes (pedal-assist only, maximum 20 mph) are permitted on all carriage roads and represent an excellent option for less experienced cyclists or those wanting to tackle longer routes. Class 2 (throttle-controlled) and Class 3 (speeds above 20 mph) e-bikes are prohibited. During my e-bike rental experience, the pedal-assist technology made challenging climbs like Around the Mountain Loop much more accessible while still providing genuine exercise. Most local rental shops offer Class 1 e-bikes specifically designed for Acadia's terrain and regulations.
What should I do if I encounter horses on the trails?
Horse encounters require specific protocols for everyone's safety. Stop your bike completely and move to the right side of the trail, speaking calmly to announce your presence. Avoid sudden movements, loud noises, or trying to pass until the horse handler gives permission. During my three seasons cycling Acadia, I've found horse riders extremely courteous and appreciative when cyclists follow proper etiquette. Most encounters last only a few minutes, and many provide excellent photography opportunities of this traditional carriage road use. Rangers emphasize that horses always have absolute right-of-way on all carriage roads.
Can I bike on regular hiking trails in Acadia?
No, bicycles are strictly prohibited on all hiking trails within Acadia National Park. This regulation protects both hikers and the fragile trail ecosystems while preventing conflicts between user groups. The 45 miles of carriage roads provide extensive cycling opportunities without needing access to hiking trails. Violations result in substantial fines and potential removal from the park. Focus your cycling adventures on the designated carriage roads, which offer far superior riding surfaces and scenic experiences compared to typical hiking trails. Mountain biking in Acadia National Park is limited to carriage roads only.
When are the carriage roads typically closed for maintenance?
Mud season closures typically occur during March and April when freeze-thaw cycles damage the gravel surface. However, specific closure dates vary annually based on weather conditions and trail assessments. Individual sections may close temporarily for bridge maintenance, tree removal, or resurfacing work throughout the season. Check the official Acadia alerts website (go.nps.gov/AcadiaAlerts) before your visit for current conditions. During my spring visits, I've learned to have backup route plans since closures can change rapidly. Winter weather events occasionally cause temporary closures into May, particularly affecting higher elevation sections like Around the Mountain Loop.

The Witch Hole Pond Loop provides the ideal introduction to Acadia cycling with gentle terrain, beautiful scenery, and convenient access from the visitor center. At 4.7 miles, it offers sufficient distance to experience the carriage road system without overwhelming newer cyclists. The route includes a variety of landscapes and one of the park's scenic stone bridges, providing excellent photography opportunities. Plan 2-3 hours including stops for sightseeing and rest breaks.
