Famed ocean explorer Jacques Cousteau once said, “We protect what we love.” Throughout April, throughout the year and throughout the Florida Keys, sustainable family-friendly events are offered for travelers eager to connect with and help to protect the unique Keys environment.

Connect & Protect Florida KeysFor example, the free open-air Key West Artisan Market set for Sunday, April 7, is themed “Ocean Awareness” with a focus on artistic interpretations of the ocean realm. There you can browse among booths featuring carefully curated artists and crafters showcasing Keys-crafted jewelry, art, curiosities and other wares. There’s live music, craft beer, wine, spirits and fresh food concessions. The event takes place from 10 a.m. to 2 p.m. at Higgs Beach on Atlantic Boulevard — and don’t forget to bring your own reusable bags to carry your treasures home.

Mote Marine Laboratory’s Ocean Fest: A Community Celebration will salute the unique marine environment of the Keys from 10 a.m. to 5 p.m. Saturday, April 13, at Key West’s Truman Waterfront Park. At the free event, you can explore conservation and environmental exhibits, experience touch tanks, meet live marine animals, hear insights from Mote scientists and researchers, browse and buy works by local marine artists and craftspeople, and rock to live music. Plus famed marine life artist Wyland plans to paint with attending children and auction his work. Proceeds benefit Mote Marine’s coral restoration efforts. And be sure to stop by the Florida Keys Eco-Discovery Center, a visitor facility for the Florida Keys National Marine Sanctuary, adjacent to the park at 35 E. Quay Road.
