Now in its 20th year, the Bailey-Matthews National Shell Museum on Sanibel Island is the only museum in the United States that is solely devoted to shells and mollusks. The museum exhibits beautiful shells from around the globe, and its world-renowned malacologist and two marine biologists are joined by highly educated guides who offer a wealth of knowledge, surprising facts, and rare insights into the lesser-known complexities of shells. Yes, there’s science (and a lot of it!) but there’s also interesting cultural, historical, and culinary facets included. It can be a little goofy, but it’s a lot of fun and certainly original.
