Confirmed from Merrimack River Greenway Trail, Sunflower Section's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

“It's so rewarding to see people of all ages and abilities using the trail.”

Nice trail….five stars because it signals progress. It will be even better when it connects both north and south. But let’s applaud solid progress!!!

★★★★★ — Christopher , Oct 2024

I applaud the effort and the achievement. However if this is really intended as a multi-use trail it is too narrow. In the ideal world there would be two lanes for bikes, one going south and the other going north. A separate lane (so 3 lanes) would be clearly marked for pedestrians.

Hi MRGT, I walked the trail this afternoon since I could not make it last Friday for the ribbon cutting. Wow, I'm impressed on the trail. It is a lot more than I thought we would get years ago when we cleaned up the riverbank and pushed out the campers. A good plus is I did not get poison Ivy this time. Thanks.

★★★★★ — Spruce , Oct 2024

It's so rewarding to see people of all ages and abilities using the trail. It will be even better when the connection is made to the segments by Terrill Park and over the new Loudon Road bridge, and who knows, maybe over the river to a deck-park by I-93.

Trail conditions & character

What this trail is actually like underfoot and overhead, taken from its own listing and from reviews. Each one links to every other trail with the same character. Busy or quiet is reported as a plain fact, not a plus or a minus — a runner heading out alone at dawn often wants company on the path, and someone running intervals wants an empty one.

🪵 Boardwalk

“This is particularly important for the boardwalk if it’s going to be safe for all users.”
