Being able to camp textile (required clothes) and then walk to a nude beach is a good option - but quite rare except in Europe or at all-gay c-o resorts.
You can find some at Palm Springs,
Key West, FL
Haulover Beach (Ft Lauderdale, FL,)
Russian River area - 90 miles north west of San Francisco in and around Guerneville.
See http://www.highlandsresort.com/ -they had campsites available - but the nudity must be restricted to pool and jacuzzi.
There is also the possibility of some naughty free skinny dipping while floating down the Russian River.

Baker's Beach in San Francisco (no camping of course but you'll feel it's the great outdoors once you're inside the Golden Gate Park and surrounding recreation areas.
and Provincetown (Cape Cod,Mass) - although there has evidently been a crackdown on public nudity (by anyone) at the famous Herring Cove (state beach) that is 15 minute walking distance from P-town. That's what I used to do. Camp among clothed at night, spend all day among the naked during the day .
There's a commercial campground with easy walking distance of P-town (out on Hwy 6), Dunes' Edge Campground, and you can walk, bike or drive from there to Herring Cove Beach. I've heard that people still get nude at the P-town beach, but they have to be discreet because the park rangers patrol often and hand out tickets (or worse) to naked men in the sand dunes. Most everywhere they are more tolerant of non-sexual nudism, particularly where there are mixed groups.
Overseas there are many more....
Big Island (Hawaii) Kalani is a gay-owned, and nudity friendly retreat for all types -more focused on spiritual, yoga, and new age trends, the pool area in clothing optional after 4pm , and there is the famous Kehena Beach (also clothing optional and alternative / new age oriented, with a wonderful assortment of naked people from every age and walk of life.
Kalani has accommodations from camping to villa suites, meal plans or pay as you go are options.
The world's largest nude beach and sand dudes (gay cruising area) is at Maspalomas (at Playa del Ingles on southern end of the island of Gran Canaria).
That 's where I'm headed for the 5th time next month (March 15-22).. I'm not camping but staying at a two-hotel hotel for about $30 a night (self-catering), sex city at night and sunshine and naked male skins for days on the beach.
Men cruising the dunes are aged 40+ and higher so not everybody's preference.
Photo at the top shows a younger guy who was cruising naked in the dunes on Gran Canaria (on the largest of Spain's Canary Islands).
At the bottom(right) is me camping naked hear Herring Cove. Provincetown, MA.
