Lebanon's Boston Lots is an incredible place to ride. Over 30 miles of trails ranging from mellow to meltdown. Easily many days of riding and exploring.
The land manager is Dartmouth College. But the trails are maintained and loved by the Upper Valley Mountain Bike Association who's webpage has an excellent trail description as well as for many other local riding hotspots.
UVMBA is a great group and if you do more than casual riding here it would be a good group to join.
Additional information is at MTB Project.
At 1030' the high point in the Boston Lots is Burnt Hill. You'll do a lot of climbing, some quite technical to get there. Expect to do some exploring and after a few rides you'll come up with your personal favorite trailsand routes.
Since elevation gain and loss is important here I'd suggest starting from the "Nature Lot" parking lot located at 287 Mascoma Street and doing most of your climbing on trails like the Burnt Pathway. That way you'll enjoy some fantastic downhills rather tahn walking quite a bit up them. You can get a waterproof map and some trail suggestions at Mason Racing Cycles and Omer & Bob's both of which are located about 1/2 mile from the trilhead.
Be sure to check out the Kid's & Family trails. They are perfect for a warm up or a cool down.
You'll be challenged by many of the trails at Boston Lots. Especially if you're going in the wrong direction.
Kids trails, techncal singletrack awesome downhills, lots of VERY well constructed and maintained trails.
There's a lot at Boston Lots.
