If you're more ambitious there are longer sections I went on with typical New England woodland plants. I and my hiking partner were the only ones there, so social distancing is not an issue. I did have to pee in the woods because there are no bathrooms.

The dirt parking lot is just off of 117 and there are maps and booklets to borrow during your trip. The booklet teaches you about fauna & flora found off the trails. Additionally, you can see the old lime quarries and lime kiln. Nice place to visit if you're a local.

Currently there is ample parking but during the height of the pandemic sometimes the lot would fill up. The landscape is a mix of woodland and a few marshier areas by slower sections of the river. Amazingly there were no mosquitoes though you wouldn't think they would spray for them in a conservation area. Further down the road is a spot where you cam put kayaks and canoes in the water.

Wide, relatively flat, and well cared for trails follow the Nashua River and passes by the remains of the Shoeshank Mill. Wildlife seen include wild turkey, white-tailed deer, tufted titmouse, & American robin. Plenty of shore fishing and two unofficial swimming spots complete with rope swings can easily be found. There are two picnic tables by the river. It would be pretty easy to walk a kayak down to the river edge though there is a kayak put in further up route 70 (towards Lancaster center). NO AMENITIES. Please carry out your trash (especially your bags full of dog poop). Sadly, there are a lot of poop bags and Dunkin' Donuts trash, especially near popular fishing spots as of late.

We took the Chasm trail but the trail off it to the chasm itself was closed for repairs. Hit the Summit trail and didn't see an overlook at the top, just an ugly concrete water tower. My now my knee was bothering me as I am not a spring chicken, so we went back down to the parking lot. Looked at the map and saw it was quite a ways beyond the water tower to the lookout. I probably could have made it to the outlook and back if I hadn't gone off on the chasm trail. Maybe this is a better site for younger folks, though they did have reading glasses at the kiosk for older folks like me, which I've never seen anywhere before and which, along with clearly marked trails, got them a second star.

The 3.3 mile trail was pretty easy and took me an hour to complete. When I came at 3:30 on a Thursday there were only 2 cars in the parking lot. When I left at 4:30 there were 7 cars at the trailhead. Nice place. I was staying at the minuteman campground and it was only a 5 minute drive from there.
