Explore Greater Portland's Top 8 Bike Routes: From Islands to Lighthouses (2026)

In the enchanting world of cycling, where the wind whispers through the spokes and the sun dances on the wheels, there's a place that has captured my heart and ignited my passion: Greater Portland, Maine. This city, with its cobblestone streets and coastal charm, is a haven for cyclists, offering a myriad of routes that cater to every rider's fancy. From the serene island escapes to the thrilling coastal adventures, each path tells a unique story of discovery and freedom. But what truly sets these routes apart is the blend of natural beauty, historical significance, and the sheer joy of the ride. So, let's embark on a journey through the best bike routes in Greater Portland, where every turn reveals a new adventure and every pedal stroke brings us closer to the heart of this captivating region.

One of the most captivating routes is the Portland to Mackworth Island trek, a 10-mile round-trip that takes you on a journey through time and space. Starting from the bustling downtown, you'll glide along the Back Cove Trail, where the stone dust under your tires whispers tales of the city's past. Then, you'll cross the Martin's Point Bridge, a testament to human ingenuity, and turn right onto Andrews Avenue, which leads you to the serene Mackworth Island State Park. The island, with its day-use fee of $3 for Maine residents and $4 for others, is a sanctuary of natural beauty and historical charm. Most of the route is on roads, with bike lanes offering a sense of security, and the short section on the Back Cove Trail adds a touch of adventure. This route is a perfect blend of urban and natural, making it a must-ride for any cyclist.

But the adventure doesn't stop there. The Portland to Cousins Island route, a 30-mile round-trip, takes you on a journey to two islands, each with its own unique charm. Starting from Portland, you'll follow Route 1, a road that winds through the landscape like a serpent, and turn right onto Route 88, a road that leads you to the serene Cousins Island. The speed limit on Route 88, a mere 35 miles per hour, ensures a leisurely pace, and the decently sized shoulder provides a sense of security. This route is a testament to the beauty of coastal Maine, with its lighthouses and ocean views, making it a must-ride for any cyclist seeking an escape from the mundane.

For those seeking a longer adventure, the Portland to Brunswick route, a 58-mile round-trip, is a journey through the heart of Maine. Thanks to Adventure Cycling's Short Routes, this route is a well-trodden path that takes you through the landscape like a river. With multiple bus stops along the way and the Brunswick Amtrak Station as your final destination, this route is a perfect blend of adventure and convenience. Starting like the Cousins Island route, you'll turn onto Tuttle Road after about 5 miles on Route 88, and then bike on Route 1 for a little while. South Freeport Road will take you to Freeport, and Pleasant Hill Road will get you to Brunswick, a journey that is both challenging and rewarding.

The Back Cove and Eastern Promenade route, a 6-mile loop, is a favorite among locals and visitors alike. The Back Cove Trail, lined with stone dust, is a haven for cyclists and pedestrians, offering a serene escape from the city's hustle and bustle. Near Tukey's Bridge, you can join the Eastern Promenade Trail, a paved waterfront trail that offers a breathtaking view of the ocean. The total distance of your ride will depend on where you start on the Back Cove Trail and if you're doing a round-trip, making it a versatile and enjoyable route for all.

The Eastern Trail, a 16-mile route, is a testament to the power of human ingenuity. Thanks to a newly completed section, you can now bike from Bug Light Park in South Portland to Saco almost entirely off the road. It's a journey through the landscape, with a small section on Eastern Road adding a touch of adventure. There are a few miles of gravel when crossing the marsh that might not be ideal for some road bikes, but the overall experience is a testament to the beauty of Maine's coastal regions.

The Tour des lighthouses, a 15-mile and 25-mile route, is a journey through the history and beauty of southern Maine's coast. Starting from Portland, you'll travel to South Portland over the Casco Bay Bridge, a journey that can be stressful for some, but the bike lane offers a sense of security. As you move south along the coast, you'll encounter Bug Light Park, Spring Point Ledge Lighthouse, Willard Beach, and the iconic Portland Head Light. The longer, 25-mile version includes two more lighthouses and more ocean views, making it a must-ride for any cyclist seeking an adventure.

The Cape Tour, a 45-mile route, is a journey through the best views, lighthouses, and beaches in South Portland, Cape Elizabeth, and Scarborough. With multiple versions available online, this route is a testament to the diversity of Maine's coastal regions. You can choose not to stop at Willard or Higgins Beach or to skip some lighthouses, making it a versatile and enjoyable route for all. The route is a mix of roads and trails, including some higher stress areas in Portland and by the bridges, but the overall experience is a testament to the beauty of Maine's coastal regions.

In conclusion, the best bike routes in Greater Portland are a testament to the beauty of Maine's coastal regions, offering a blend of natural beauty, historical significance, and the sheer joy of the ride. From the serene island escapes to the thrilling coastal adventures, each route tells a unique story of discovery and freedom. So, whether you're a seasoned cyclist or a novice rider, these routes offer a wealth of experiences that will leave you with memories to cherish for a lifetime. And who knows, you might just end up obsessed, like me, with the beauty and charm of Greater Portland, Maine.
