We used to live in CT but moved to FL. We are visiting family and friends in October. How much does it cost for out of state travelers to enter Hammonasset Beach State Park on the weekend?

October there are no fees

If your a non resident its $15 dollar's for the day for a beachpass/parking. This gets you to the beach not campground.

The cost has risen but I believe it's $20 for the day and the sites are only $22 a night

I met family at the camp site, and I believe they paid $30 for each site (?) - we were able to just walk to the beach from the site. I'd imagine the beach passes were much less?
