Marquesas Keys Charters & Adventures with Six Fins Charter

Six Fins Charter operates out of Stock Island, Florida, offering a collection of private, customizable boat trips centered on the wild and largely untouched Marquesas Keys—a small archipelago about 20 miles west of Key West. This cluster of remote islands and sandbars sits within a National Wildlife Refuge that protects a critical marine habitat, making Six Fins Charter’s trips a gateway to intimate encounters with crystal-clear waters, abundant marine life, and uncrowded coastlines. Visitors can book private snorkeling adventures to vibrant coral patches, uncover secret local sandbars accessible only by boat, or take part in eco tours that highlight the fragile ecosystem of this remote wilderness.

Beyond nature-based outings, Six Fins Charter adds flavor to the experience with options like private romantic sunset cruises that let couples soak in endless ocean views, or water-based tiki bar crawls that combine island hopping with laid-back tropical fun. Their Private Dolphin Playground Safari puts guests in the heart of pods of playful dolphins, while the Historic Harbor Cruise offers insight into the maritime lore of the Florida Keys region.

For anglers, Six Fins opens doors to patch reef fishing expeditions, and during July 2025’s lobster mini-season, guests can participate in specialized charters focusing on this short but exciting window of spiny crustacean hunting. Staying at the Perry Marina complements their trips with full-service boat access and waterfront amenities, anchoring Six Fins Charter as a standout outfitter for immersive, private marine adventures near Key West. This company delivers more than just a boat ride—it’s a tailored outdoor experience in an ecologically significant and visually stunning corner of Florida's Keys.
