The varity of shells in thes store was very nice. We wondered around looking at them all before making a slection. Plus we picked up a coupon book at the welcome center so it was an even better deal. You should check it out.
When you tire of actual beach, whether be sunning, beach combing for shells or exercise or fishing; go shopping at the MANY unique shops on Sanibel on Perwinkle the main thoroughfare...Wide selection of items, for sure. Restaurants, retail shops, bike rentals, etc
Periwinkle Way starts as soon as you exit the Causeway onto the Island and goes past nearly everything worthwhile on Sanibel. Lots and lots of shops (shell, souvenir, fishing charter, etc., etc.), a huge selection of bars and restaurants as well. It's hard to not drive it and be on Sanibel.
