If you are lucky enough to live close enough, want to fight the traffic, and limit your visits to about 90 days each summer then Sandy Hook is a very popular option for enjoying naturism for very little money. But remember, the costs of operating the public beach there is spread out over millions of taxpayers because it is a State Park.

For the rest of the country, enjoying the freedom of being nude means either a once or twice a year week (or two) in the Caribbean (with all the associated costs), or finding a local naturist venue within a few hours' drive from home that has the facilities which they find inviting and people they find welcoming and then paying a fair price that allows the facility to stay in business, operate, maintain, and improve those facilities, pay the electric, gas, and water bills, pay the staff a living wage, and provide the owners with some return on their large investment...with no funding from the taxpayers!

You get what you pay for...
