We took a drive over the causeway, which is a toll road, to the islands of Sanibel and Captiva. We started at the tip of Sanibel Island at the Sanibel Lighthouse. You have to pay to park. Don't forget your sunscreen, a towel, and some water. Pack a small cooler for a picnic lunch. This is a great place for some shelling. We drove to the other end of the island then continued on to the tip of Captiva Island for some shelling there. On the way back we stopped at the shops.
