Just a though for anyone traveling from the VA MD area. This campground is 65 miles from the closest bridge into New Jersey. Take a look at a map to see the location.
Clermont is only 18 miles or so from the Cape May Lewes ferry. So if you are coming up from the coast you may want to consider the ferry ride.
We stopped at Cape Henolopen State Park in Delaware coming back from Hatteras. Water only and $32 a night, but there were only about 10 campers in the entire park, and most of those were tenter's!
This state park is only 5 minutes form the ferry.
The ferry trip was $80, $70 for the truck, trailer and driver, $10 for each passenger. No charge for the dogs or parrot.
It is a nice ride across Delaware Bay and if you have been traveling a 1.5 hour break.
$80 isn't cheap but the distance to go around and then south to Avalon is about an extra 100 miles, plus all the tolls in MD, DE and PA. Typically there are no tolls to get into New Jersey but you have to pay to get out (still haven't figured that out)
