Recently I came across an interesting approach to accessible beach path signage while on a trip to St. George Island, FL. Look at the photo on the right. What you see there is a sand path to the beach from the parking area. Clearly, sand is not a stable, firm or slip resistant surface for disabled individuals to use. So what they did here was post a sign that says the path is not accessible, and then left a QR code to find the location of a path that is accessible. See the photo below.
