Meduxnekeag River Trail

trail is not 8’ —only at the beginning

July, 2026 by carol6041

If you take the trail from the picnic benches, the trail starts at 8’, then goes to 4’. You can’t bike past 2 people walking unless one moves over. It gets narrower. Parts have deep crushed stone not easy to push through for wheelchairs, walkers, and carriages.

Meduxnekeag River Trail

Trail needs to be outlined better on this App for biking

July, 2026 by carol6041

Trail is not flat when it leaves the river and goes up a steep hill. Bikes are not recommended beyond the trail junction. Did not take the left turn at the junction and continued on the main trail. There is a wooden sign saying “hiking trail” further down, but we believed the trail map. We tried to take the trail across the ATV bridge which was a mistake. There is a sign that says “hiking trail” and we should have turned around then! Had 1-1/2 wide gravel areas over a steep rock facade down to the water by the rte 1 and 95 bridges. After a hill, it comes to a foot-wide bridge over the water to a set of stairs. We turned around.

Southern Bangor and Aroostook Trail

LOTS OF HOLES—No warnings

July, 2026 by carol6041

Left from the Houlton KOA on Rte. 1. Can access the trail from London Rd. It has SEVERAL holes (some deep) and drainage channels across the trail. Some muddy spots. Shady spots hide some holes. Several ATV Clubs “maintain” the trail. Tried to reach Mars Hill and decided to turn around. No enjoyment since one spends one’s entire time dodging holes.

Acadia National Park Carriage Roads

Great trails and way to see the park

May, 2026 by teryandaugusto

Trails are unlike anything I’ve ridden before. They are in great shape, crushed gravel and wide enough for the crowds. Pick up a map from any of the ranger stations. Highly recommend the Amphitheater loop with the extension to Jordan Pond and the Tri-lake loops.

South Portland Greenbelt Walkway

Eastern Promenade Trail

One of our favorites

March, 2026 by strout511

Our family loves this trail for it's wide, flat route that provides great views of the bay, connections to other trails like the Back Cove Trail and the Bayside Trail, and connections to the Old Port and Eastern Prom (beach, playground, greenspace, etc.).

Kennebec River Rail Trail

We LOVE this trail!

September, 2025 by janeknickerbocker13

Virtually perfect. Low grade ups and downs. Trail is on street through village of Hallowell. No shoulder, lots of traffic, so we walked our bikes down the sidewalk and enjoyed looking in the shops. A good deal of walkers and other bikers here and there, but manageable. Start in Augusta .5 miles in, big parking lot.

Southern Bangor and Aroostook Trail

Gravel Ride from Houlton, Maine

September, 2025 by dandmhoward

This is a great trail. It is definitely a gravel ride with wide tires and low pressure.

The visitor center in the description no longer exists. If you want to start here, you have to park at Hannaford or Walmart. However, the access behind the Hannaford grocery is not a rail trail. It is an ATV trail with steep slopes, tight curves, boulders, and rough ground. I recommend starting where the trail crosses B Rd. or, as we did, where it crosses Gogan Road.

Once on the rail trail, it is one of the best gravel rides, no traffic except for a few ATV's with very courteous drivers. The speed limit is 15 mph and only once in several years of riding did we ever see anyone going faster.

One note of caution, I recommend walking across the bridges. They have very wide gaps that run parallel with your tires and many have loose nails and screws.

I highly recommend this trail.

Sanford-Springvale Rail Trail

very peaceful

September, 2025 by boppa

Started at Oak Street trail head parking lot. Headed south, roughly 4 miles out and 4 back. Well maintained crushed packed stone. Best to turn back at Carpenters Bridge if bicycling without fat tires. Part after Carpenters Bridge is Sandy and moguls from ATV use.

Back Cove Trail

Back Cove

September, 2025 by boppa

I have biked several times over the past 4 years. Nice ride but this past ride (Labor Day week) there was a lot of foot traffic which required a lot of stopping. Usually a nice ride but I guess I picked the wrong day.

Acadia National Park Carriage Roads

These trails are a must!

August, 2025 by bdangrueter

My husband and I rode the trails with two of our teenagers. We all had e-bikes, which isn’t necessary, but came in handy on some of the hills we had to bike up (I shouldn’t really say hill, it’s a mountain!). We brought two and rented two from Southwest Cycle in Southwest harbor. They were excellent quality. The carriage roads are well maintained and there are signs that are easy to follow to lead you to different destinations. There are also many scenic spots to stop and take photos or just hike around if you want to.

Belfast Rail Trail on the Passagassawaukeag

Beautiful bike ride

July, 2025 by garylee.ebay

You can’t beat this. Start down south at the boatyard and go north to the end. But don’t end there- go right over the bridge then head back south on the quiet paved road down to footpath road. Takes you back to the start. Remember to be respectful on your bike / e-bike
