Best and nearest to beach Florida RV parks

Try Beverly Beach on the east coast. Camping right on the Atlantic ocean.

Topsail state park, Destin Fl. July of this year we will be there for 4 days..

I Love This Park. Its not cheap but for once a year vacation .

When you can get a campsite on Loop A, Fort Pickens Campground in Pensacola is a delight. Beautiful white sand beach right across Pensacola Sound from NAS Pensacola which is home for the Blue Angels. You might get to experience one of their air shows on a Wednesday during their "season". Rejoice!

Oh ya, I forgot. There is a trolley service that stops in front of the park that will take you all over FMB.

Red Coconut RV Park in Fort Myers Beach has sites right on the beach and 3 or 4 rows in. Also sites across the street in the 'park side'. Sites are a bit tight but we love it there. Easy walk to restaurants and you could bike easily to get groceries. You can rent bikes locally. Make reservations NOW!

Gamble Rogers at Flagler Beach is a State Park on the beach. It may be tough to get a reservation though. There is a privately owned Campground in Beverly Beach, is right on the beach.
Good Luck

Jetty Park at Cape Canaveral has a lovely beach. Some of the sites are very close to the beach. It is a county park but the prices are high for a county park in my opinion.

Further north of Daytona is Gamble Rogers S.P. and Anastasia SP at St. Augustine. Both are on the Atlantic and have nice beaches.

Jetty Park which is a city owned park, near Melbourne, as close to the beach as you are likely to see but it's still a couple hundred yards. Anastasia State Park near St Augustine is on the beach. There are some panhandle state parks on the beach but I haven't been to them.

Of course the parks in the Keys all have beach access both private and state.
