Overlooking the sparkling waters and pristine beaches of the Boca Grande Pass off the southern tip of Gasparilla Island, the Port Boca Grande Lighthouse has been a beacon of safety to sailors since it was erected here in 1890. With a completely different look from the Sanibel Lighthouse to the south, this one has a more residential aesthetic. And, indeed, the lighthouse once served as the home for five successive families of light keepers. Today, it houses a museum where you can get a fascinating look at the area's history as far back as 12,000 B.C.E. Make time to browse the gift shop and let the kids stop at the "please touch" area where they can put their hands on bones, fossils, and shells collected in the local area.
