Noanet Woodlands is another favorite woodsy area to add to my list (another recent favorite is…read moreanother Trustees property in Andover, the Ward Reservation). The two are somewhat similar with different color coded trails and a trail to reach a summit for the skyline of Boston (I didn't check that out here at Noanet Woodlands for this trip). I enjoyed coming here on the weekend: it was moderately trafficked (which I like so it's not *too* isolated), and easy/moderate trails (I prefer long, ambling hikes). The only thing is that the orange trail I took was a bit confusing/not super clear. The overall system does a good job, but I would be sure to download a map/have AllTrails active to ensure you don't end up in the wrong spot. I fortunately ran into some folks who helped me get back on track, but a heads up that it could get confusing as it did for me. Otherwise, a wonderful shady (important to know on hotter days) set of trails that I would recommend!

The Western Greenway is located almost entirely inside the triangle bounded on the northeast by…read moreConcord Avenue in Lexington and Belmont, on the southeast by the MBTA commuter rail and the now-abandoned Mass Central Rail line, and to the west by Lexington Street in Waltham. To be sure, there has been a significant amount of development inside this triangle. But there are also significant swaths of green space. The green space comprises various parcels, some of which are publicly-owned and have been designated as parks or conservation land. There are other publicly-owned parcels whose future is still undetermined, and there are some undeveloped parcels along the Greenway that are privately-owned. Most of the blazed segments of the Greenway are in Belmont and Waltham extending from the Beaver Brook area all the way around past the YMCA on Lexington St. toward the Lyman Estate. I usually like to park in the lower section of the YMCA driveway, or the lot over at the Robert Treat Paine Estate off of Beaver street. There are a couple trail heads in the lot, and they are all well marked. It is a great place to walk the dogs or take a light hike. There are no serious steep uphill or challenging terrain, it's really just a great place to take a leisurely hike in the woods. We see deer and other wildlife out there all the time. It was really a shock to me when I first discovered it that there was this much undeveloped space in the heart of Waltham. There are many marked and blazed trails, but the Greenway is still under development in certain sections. It is worth a visit to the Waltham Land Trust website to see what areas are suitable for what your looking to do.

It may sound a bit corny, but Lone Tree is so peaceful and secluded from everything that you can walk around for hours. Most of the trails are in the woods or in the fields. During the spring, you will be walking through fields covered in thousands of white daises. The trails are commonly used for dog walks and the occasional bike ride. I also sometimes see people with metal detectors hoping to hit the jackpot, but that's only in the summer. There are so many hidden paths and if you go a certain way, you will a couple of abandoned buildings filled with graffiti. I cannot recommend these trails anymore than I just did.

Personally I'd like to see an option for those of us living in the Blackstone Valley (and others) to purchase an annual sticker. Similar to the way you might support a local zoo, for example. They would likely get higher donation amounts voluntarily, vs. the extortion-like pay-to-park each visit. Beyond the parking... For those seeking heat relief, on a hot summer day the low parts of the chasm are considerably cooler. Of course this does generally bring the crowds. Remember to bring bug spray. Children will be in awe of the rock formations and most will absolutely love climbing over, under and through the rocks, crevices and small caves. The rocks are normally slippery, more so after a rain or during the humid summer months - decent footwear is a must. Grandparents beware: not the best place to try to follow an 8 year old! However, across the street by the visitor center there's a nice playground for the kids to tire-out. If you want a longer/safer/less slippery hike you can follow Charlie's Loop trail in it's entirety (start by the covered picnic tables). Then maybe veer off onto the northwest side fire road. From there you can find a couple of trails that head back toward the parking lot. This is a great place to walk the dog(s) - leashed. Please pick up after your pet. Also a wonderful spot for snowshoeing - assuming we still get snow. re: parking - if you are local you might find a place over on Mendon Road, from which you can enter the park via the fire road (47CF+628).

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.
