Smathers Beach is frequently cited as the number one beach in Key West for those seeking the classic "tropical" experience of soft sand and palm trees. As the island's largest public beach, it stretches for about two miles along the southern shore and offers shallow, calm waters that are perfect for swimming and sunbathing. For travelers who prefer nature and history, Fort Zachary Taylor Historic State Park is often the top choice; while its shore is more pebbly, it offers the best snorkeling on the island and stunning sunset views. In 2026, Smathers remains the "go-to" for free public access and amenities like volleyball courts and food trucks, while Fort Zach is the premier spot for those willing to pay a small entrance fee for crystal-clear water and a more serene, protected environment away from the main resort crowds.
