6491 Sanibel Captiva Rd

"Popular for fishing and shelling, this beach stretches under the Blind Pass Bridge, placing it on both Captiva and Sanibel islands. Swimming here is somewhat dangerous because of swift currents, but walking the shallows looking for pretty shells is a fine way to spend an hour or two. You can park on either side of the bridge to access the beach, but know that there aren’t any restroom facilities on the Sanibel half."
