A network built for the landscape
Acadia’s carriage roads make a connected riding network rather than a single point-to-point route. Their crushed-rock surface winds through the heart of the park, around mountains and valleys, with sweeping views and close-up landscape encounters away from car traffic. The system was built from 1913 to 1940 under John D. Rockefeller Jr. and his family, and is maintained by park staff and volunteers. NPS
The roads pass beneath and over historic bridges, each with its own design. Rockefeller financed 16 of the 17 stone-faced bridges. Their structures use steel-reinforced concrete, faced with native stone so they sit naturally among streams, waterfalls, roads, and cliff sides. The result is a route where bridges are not just crossings but recurring landmarks in the park’s road-building history. NPS
Read the intersections
The network’s scale makes route choice part of the outing. Bring a carriage-road map to plan between intersections; historic wooden directional posts carry numbers that correspond with maps and guidebooks. Riders can bring their own bicycles or rent from local outfitters. The numbered junctions make it easier to choose a manageable section or link several stretches without treating the whole system as one ride. NPS
Look for the cedar signposts and the rough, irregular granite blocks lining the roads. The stones serve as guardrails and are known as “Rockefeller’s teeth.” At Jordan Pond and near Northeast Harbor, gate lodges mark entrances to the system. These features make the route legible on the ground while reflecting Rockefeller’s attention to details of construction and design. NPS
Choose a surface and season
Packed gravel is more even than many bicycle surfaces and the carriage roads are described as mostly accessible; wheelchairs are permitted. Still, the route is a gravel network, so a rider choosing a section should consider their comfort on that surface. The park lists the roads for winter, spring, summer, and fall, but seasonal conditions affect whether bicycles are allowed. NPS
In spring, mud-season closures often affect all traffic, typically in March and April. During winter, bicycles are prohibited where roads are groomed for skiing. Check posted notices for temporary closures before setting out. This matters especially when planning around a particular bridge or junction, since a closure can change which parts of the network are available. NPS
Share the roads
Cyclists share the carriage roads with pedestrians and horses. Everyone yields to horses, and bicyclists yield to everyone. Class 1 e-bikes are permitted; Class 2 and 3 e-bikes are not. The speed limit is 20 mph, and bicycles are not permitted on hiking trails or privately owned carriage roads. NPS
Dogs must be leashed no longer than six feet, and riding a bicycle with a dog is not recommended for safety. These rules shape the character of the outing: the carriage roads are a shared, non-car route where a steady pace and attention at intersections help preserve room for other users. NPS
