Sanibel-Captiva Road to Blind Pass. It s just after the bridge to Captiva, on the left. Be careful swimming the water gets deep quickly and there can be a strong undertow. Good fishing from the beach and on the rock jetty there. Great place for sunsets, romantics.
Parking is no longer free.
Bars and restaurants are across the street nearby. A really nice spot for shelling is at Blind Pass beach just before this one, other side of the bridge. Parking is 75 cents and hour there as well, or accessible by walking across the bridge. Either side of causeway. This long, thin stretch of beach starts just before the toll gate and continues along the causeway.
