Started on the Wakefield side off RT 16. I enjoyed the challenge of the rails still in place. Keeps it fun and challenging! Each crossing had a sign saying to walk your bike over the rails, not sure how so many people fall walking there bikes over the rails. The rails can be challenging when passing oncoming people. I’m not ranking the trail lower for this, but some people would only get a one ¿¿ review ¿ Bring a picnic and enjoy the state park!
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.
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.
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.
We probably crossed the rails 15 times before my wheel caught and I went down, scraping my knee and hands, I got pretty bruised up. I couldn’t bend my knee to ride back and uber was not an option. So my husband rode back to the other end to get the car. This is dangerous and the trail is narrow for bikes and walkers at the same time. We had to stop so that bikes in the opposite direction could pass. Would be a nice ride if it were fixed up a bit.
Trail is nice and flat, some soft dirt (minimal), and small rocks across bridge. Trail needs a good chain drag, roots cut back, and rake. Otherwise it’s a good dirt trail with lots of shade. Excellent for walking dogs too!
Nice comfortable ride we started in the parking lot in North Hampton and came out on Borthwick Ave near the hospital 17 miles out and back route that will be pretty in the fall
Very poor it's not what it say you have barriers that you can't fit a trike through needs a lot of work Very little pavement on it.
I enjoy taking a walk before or after running errands. This path has filled a need in the Mt Washington Valley! The paved surface is welcoming and checking out the turtles on the north end of the pond is fun. Enjoy!
This is a very enjoyable trail from Augusta to Gardner. Much of it is along a high bank of the river with wooded views to the east side. At the Augusta side, in season large sturgeon jump high and loudly flop into the water below the damn. Passing through Hollowell is a treat with its interesting shops and a great halfway stop for drinks and/or food at its several restaurants. Gardner on Thursday evenings has an antique car show in the river park with music and food trucks.
Great trail to ride on, well maintained crushed stone path. We got on at mile 13.4 in Portsmouth and rode to mile 6.8 then turned around and headed back. A lot of tree coverage which is nice for shade but not much variation in scenery. Not sure if there is more to see further south on the trail. That being said, it’s still a great place to get outside and exercise!
