I started a new thread with a relevant title. We are staying near Blind Creek (Ft. Pierce/Jensen Beach/Hutchinson Island, FL) for a month. Here is info on lodging.

Well there sure is no Club O but there are lots of lodging options near Blind Creek nude beach. Check out the Treasure Coast Naturists website for the closest ones:

Note that their map shows the Jensen Beach Inn in the wrong place. It is not in Ft. Pierce but rather in Jensen Beach, as per the name!

There are also lots of motels just off the island in Ft. Pierce and Jensen Beach as well, all within a half hour of the beach.

We just rented a condo via AirBnb, they had many options on Hutchinson Island depending on your timeframe. We are kind of off-season so finding a place wasn't hard.

For those with an RV and you want nude-friendly accommodations near Blind Creek you could give Sunnier Palms a call.
