Glad you asked. I'm Actually a park ranger at Rocky Neck! As of last year CT has added a $10 fee on every vehicles registration every two years allowing for there to be no charge for CT residents. Just remember if you are in a vehicle with out of state plates you will have to pay the out of state cost even if you show I'd or valid CT registration.
Free for CT Residents
It's free for CT residents with CT car plates
It's free for Connecticut people, as long as it's a Connecticut car license plate.
Well we paid nothing to get in I'm assuming because of our ct plates on the car so I would say nothing. Hopefully that helped.
