Private Trip
Scuba Diving
12hour private charter to Flower Garden Marine Sanctuary offshore.Three scuba dives at Stetson Bank from different mooring buoys.Small group diving experience accommodates up to six guests maximum.
Picture yourself 90 miles from Houston's coastline, floating above one of the most pristine underwater ecosystems in the Gulf of Mexico. The Flower Garden Marine Sanctuary isn't your typical Gulf dive – this protected paradise sits in crystal-clear blue water where visibility regularly hits 80-100 feet. Your private 12-hour charter with Action Outdoor Fishing & Diving takes you and up to 5 buddies to Stetson Bank, where three separate dives from different mooring buoys reveal why this spot ranks among the top-rated dive destinations in Texas waters. No crowded cattle boats here – just your group and some of the healthiest coral formations you'll find this side of the Caribbean.
This isn't a quick splash-and-dash operation. You're looking at a full day on the water, departing early morning for the 3-4 hour run to reach the sanctuary. The boat ride gives you time to suit up, check your gear, and watch the water transform from that familiar Gulf green to the deep sapphire blue that signals you've reached the continental shelf. Stetson Bank rises from 200 feet to about 60 feet below the surface, creating an underwater mountain covered in massive brain coral heads, colorful sponges, and swim-throughs that'll have your underwater photographer friends drooling. Each of the three dives targets different sections of the bank using permanent mooring buoys – no anchor damage here, which is why this place stays so pristine. Expect bottom times around 30-40 minutes per dive, with surface intervals perfect for swapping stories and refueling between drops.
You'll need to bring your own gear for this adventure – we're talking full scuba setup including wetsuit, BCD, regulator, mask, fins, and dive computer. A 5mm wetsuit works great year-round since the Gulf stays relatively warm, though winter months might call for a 7mm if you run cold. The boat provides tanks and weights, plus they've got emergency oxygen and first aid gear onboard. Before each dive, you'll get a thorough briefing on the site layout, current conditions, and marine life to watch for. The mooring buoy system makes entries and exits straightforward – no fighting current to get back to an anchor line. Most dives here are suitable for advanced open water divers and up, though the depth and offshore location mean this isn't beginner territory. Current can pick up between dives, so good buoyancy control and comfort in blue water conditions are essential.
Manta rays are the rock stars of Stetson Bank, and summer months from May through September give you the best shot at these gentle giants. These massive filter feeders, with wingspans reaching 12-14 feet, cruise the bank feeding on plankton and often approach divers with curious intelligence. They're most active during cleaning station visits where smaller fish remove parasites – a behavior that creates world-class photo opportunities. The mantas here aren't shy either; many divers report 20-30 minute encounters with the same individual ray.
Hammerhead sharks patrol these waters year-round, but your best chances come during cooler months from November through March when they school in larger numbers. These prehistoric-looking predators, typically 8-12 feet long, use the bank's structure as a highway for their migrations. They're generally wary of divers but provide heart-pounding moments when they ghost past in the blue water beyond the reef. Early morning dives often produce the most shark activity before boat traffic picks up.
Goliath grouper are the neighborhood bulldozers – massive fish that can exceed 400 pounds and have zero fear of divers. These protected giants hang out in the larger coral formations and swim-throughs, often posing for photos with an almost dog-like curiosity. Summer spawning season brings them together in impressive numbers, and their low-frequency booming calls create an otherworldly soundtrack to your dive. Don't be surprised if one follows you around the entire dive; they're known for their bold personalities.
Loggerhead sea turtles treat Stetson Bank like their personal cleaning spa, regularly visiting to have algae and parasites removed by resident fish. These ancient mariners, some weighing over 200 pounds, move with surprising grace through the coral formations. They're most common during spring and summer months when nesting activity peaks along the Texas coast. Patient divers often get extended encounters as the turtles go about their business, seemingly unbothered by human visitors.
The Flower Garden Marine Sanctuary represents some of the healthiest coral reef diving in the entire Gulf of Mexico, and this private charter experience puts you right in the heart of it.
