Need a seashell to commemorate your beachside holiday? On Florida’s Captiva Island, the South Seas Island Resort introduced a Shelling Concierge who can help guests find the perfect keepsake during weekly guided beach walks. Besides more than 250 species that include Conch, Lightning Whelk, Cockle, Scallops, Murex and Coquina, guests can try to track down the elusive and highly sought-after Scaphella junonia, also known as Juno’s Volute. Many guests regard finding the beautifully spiraled and speckled shell as the high point of their shelling expedition. While on the island, guests are also invited to stop in at the Sanibel Sea School to learn more about both shells and marine conservation.

Located on Captiva Island within a 330-acre wildlife preserve, South Seas Island Resort has two miles of white-sand beaches, 20 swimming pools, tennis, beachfront golf, fishing, yoga, a variety of watersports, eco-cruises and nature tours. Accommodation choices include 471 guest rooms, suites, condominiums and private home rentals. All have either balconies or terraces. Dining options are casual, with a focus on freshly caught seafood. The resort also boasts its own photography studio, plus painting classes, a fitness center and yoga studios. The full-service Kay Casperson Lifestyle Spa & Boutique offers a 4,000-square-foot space for a host of relaxing and rejuvenating treatments — plus plenty of retail therapy.
