Just stayed at Henderson State Park Destin. I think $33 a night. Across from Bass Pro Shop. 1/4 mile bike/walk to the beach. Some of the larges sites pull thru I seen. E/W only. Great for us for a weekend.
We do "Camping on the Gulf" every year and every year I look for a comparable park right on the beach. I have yet to find one. They have a giant slide for the kids, pool, and "Bubba" the gator. What more could you ask? We pay closer to $120 about 20 yards from the beach(theres no sewer on the beachfront).
