Most towns in NWCT don't have hotels/motels. The only ones who really do are Kent and Cornwall, and they ain't cheap. I'm not sure about AirB&Bs. That being said, the Appalachian Trail runs through there, and you can do parts of it with varying difficulty levels. I would also recommend hiking up to the top of Bear Mountain in Salisbury, as it's the highest "peak" in CT, and on a clear day you can see all the way to Vermont.
