Sanford-Springvale Rail Trail

Wide Tires Are Best

May, 2021 by capekat777

Today marked my first time on the trail after moving to the area at the end of last year. Great for walking/hiking but not so much biking unless you have really wide, sturdy tires. Around the Lebanon line the trail seems to have been heavily sanded, which means very tough going for casual riders. Seasoned riders will appreciate the solitude and scenery. Next time I go I’ll likely walk.

Auburn Riverwalk

Auburn Riverwalk

April, 2021 by heidifferguson

This is a great place to walk with a wheelchair or stroller, thanks to the tar, cement and brick walkways. I took my mom in her wheelchair and she was able to see swimming ducks, the river and the falls from her chair thanks to the open fencing and observation decks on the bridge. It's a well used trail, and goes past restaurants and apartment buildings. A great place in the city to enjoy nature.

Norway Branch Rail Trail

Paved path that runs parallel to the tracks- an excellent ride for the family- some hills and a couple stops at intersecting roads. About 5 to 6 miles round trip.

Androscoggin River Bicycle Path

nice little ride

April, 2021 by irisjw28

This is the second time I go bike riding in 20yrs and this path was so nice n easy. I found there to be a couple slight slight inclines but, not bad at all considering how out of shape and how long it’s been since I’ve gone bike riding. Beautiful little views. Beautiful little picnic areas. I saw all ages on the path from like 3yrs to 80s either bike riding, scootering, walking, or jogging. Definitely a nice little place to go.

Androscoggin River Bicycle Path

Nice Bike Ride

April, 2021 by irisjw28

This was a cute little path to ride. I’m just getting back into bike riding after like 20yrs (seriously) and this path was awesome to ride. Today was only my second time taking my bike out. There were a couple slight inclines that weren’t bad at all. I did have to take a break or two before continuing on them but that’s only because it’s been so many years for me. I even saw little kids riding their bikes (3-5yrs) and elderly folks as well! Amazing little path. ¿¿

Cotton Valley Rail-Trail

Excellent Ride

March, 2021 by fjg6p22mpx

I rode this trail on my mountain bike with my 3yr old nephew in the rear-mounted toddler seat. Excellent ride with terrific views, plenty of spots to safely pull aside, if necessary. Yes, as others have said, the trail does get narrow on the causeway. However, visibility is excellent. One has plenty of time to adjust their position for oncoming riders & pedestrians. The transitions over the rails are very well marked. The transitions should cause no issues for a mountain bike, hybrid or gravel bike. This would not be a trail for a true road bike with slicks or narrow tires, as a rule. Rode mid-week at the height of summer with no issues navigating other users. Enjoy!

Eastern Promenade Trail

nice city trail

February, 2021 by nyedog27

Walked this trail three times during a weekend in Portland. The trail was plowed and maintained well in the winter. Information stops along the way were interesting and the scenery was lovely

Cotton Valley Rail-Trail

Fantastic Trail for Biking

October, 2020 by leeds.nudd

Very confused at some of the reviews here. Fit mid-30s guy here, though rarely bike, completed the entire trail both ways today on a hybrid rental bike. Yes this trail is gravel and also now plenty of fallen leaves, and it’s perfectly appropriate for a bike ride as long as it’s an appropriate bike. Don’t try to take a road bike with skinny tires on this trail. Enough room along the majority of the trail for bikers to pass each other without stopping, although, yes, once or twice along the 12 mile stretch you may actually need to stop and walk your bike when passing. Such a beautiful ride.

Cotton Valley Rail-Trail

worst possible trail for bicycles

October, 2020 by moonlightgraham2

Beautiful setting, but clearly not designed for bike riders. Much of the 12 miles of trail (Wolfeboro to Wakefield) runs between the confines of remaining railroad rails, so despite the filled-in smooth surface there is no possibility that riders approaching from opposite directions will have room to pass each other. The many walkers we encountered were all considerate to voluntarily step aside and allow us to pass, although we repeatedly needed to hold up for other riders, giving them the right-of-way. One group of riders that included young children attempting to manage the difficult passages unsupervised caused my wife to take a bad fall. We have used and enjoyed many rail trails in NH -- this one deserves to be crossed off every bicycler's list.

Sawyer River Trail / Sawyer River Road

Very pretty in the fall

October, 2020 by jim_wang

I started from Sawyer River Road parking lot and biked all the way to Swift River near 112 which blocks bike access. So technically you cannot finish the whole trail, even very close. Sawyer River Rd is very good to bike. But think about Sawyer River Trail again before you continue. The trail is not maintained for biking. I had to carry the bike in several locations. There is a big falling tree completely blocking the trail.

The whole trail is very very pretty in the fall. I uploaded some photos.

Kennebec River Rail Trail

Easy Ride

September, 2020 by slipsoup

We rode this trail from the Water St. parking lot in Augusta. This is virtually the beginning of the trail except for a very short segment that goes down to a park at the river level. The trail takes a break in Hallowell's Granite City Park. There is some historical information here and Adirondack chairs set up to view the river. At the Park, the trail goes onto the street for less than a mile (stay on the main street). There are some really cool old buildings in the town. The trail then goes up to the right. This is a relatively flat and easy ride. It is all paved with few bumps.
