The Tunxis Trail is a nice hike in CT. It doesn’t loop but offers some interesting features and is very lightly trafficked. I believe I’ve only crossed paths with another person once in the past year. I started hiking it toward the end of 2018 and recently started hitting this trail again. I’ve probably walked parts of it 8-10 times.
Getting my bearings about half way. 
Today was a little spooky with the fog. Fox enjoys this trail because it is very lightly trafficked (so he can be off-leash more of the time). 
Keep your eyes open for this camouflaged feature on the trail.
