I would check out trailforks.com, and download the app. Within the app I would download the CT trail map so you can still navigate when you lose cell service.

Sunnybrook State Park has some nice hiking, as well as an RC airfield.

The mountain biking is incredible at Burr Pond- I know people who drive an hour to ride their (though it's not really beginner friendly). People hike there as well.

If you have access to a kayak or canoe Stillwater pond is a nice place to chill on the water.

So, there's my 3 favorite spots within 10 minutes.

Go a bit further, there are ski areas (Mohawk and Ski Sundown), lakes trails, etc.

Lots of nice scenery to the west - the Housatonic River wasn't industrialized like the Naugatuck.

And if you like more manicured trails or are walking with someone of unkown stanima, white memorial in Litchfield is a good spot with many different places to park. My wife and I are amazed at all the wildlife we see on the water.

DM me if you want to connect or have any questions.

People talk a lot of shit about Torrington; My wife and I call it the Jewel of the Northwest.
