Captiva & Sanibel Island Shelling Beaches Smaller shells can be found by Lighthouse Beach, while large shells can be found near the north end of Captiva. Here are a few of the top shelling beaches: Turner Beach. Blind Pass Beach.

Captiva Island is a world-renowned destination for "shelling," and Turner Beach, located on the southern end of the island near the Blind Pass bridge, is widely considered the best spot for finding treasures. The unique geography of the Gulf of Mexico combined with the way the tides turn around the tip of the island creates a natural funnel that deposits vast quantities of shells onto the shore. Here, you can find everything from common cockles and fighting conchs to the highly coveted "Junonia" shell. Another excellent spot is the beach access at the end of Alison Hagerup Beach Park on the northern end, which is often quieter and offers a fresh "wash" of shells after a storm. For the best shelling results, enthusiasts recommend going out during low tide or immediately following a cold front or storm, when the churning Gulf waters push deeper-sea shells onto the sand. The "Captiva Crouch"—the posture of people bent over searching for shells—is a common sight here. Just remember that it is illegal to harvest "live" shells (those with a living organism still inside), so always check your find before adding it to your bucket to ensure you are preserving the local marine ecosystem.
