With no development on the island—no roads, no hotels—it’s a slice of old Florida, perfect for reconnecting with nature.
The venture is ideal for those seeking a laid-back, yet adventure-rich experience in Southwest Florida. With a moderate activity level, it’s suitable for families and casual adventurers alike. Guests should come prepared with comfortable footwear, sun protection, and a sense of curiosity.

THE ROUTE
A short cruise to a true barrier‑island refuge
The trip runs from a Fort Myers marina out to Cayo Costa, an island accessible only by boat; the shoreline here is left wild and undeveloped, which is why shelling and beach time feel secluded.

THE BEACH
Pristine beaches for shelling and picnics
Once ashore you get extended time to beachcomb for shells and eat a packed picnic on miles of unspoiled sand—this is emphasized as the core reason to take the cruise.
