**Flower Garden Banks National Marine Sanctuary** A secret coral 'garden' in the Gulf of Mexico  fish and coral*Located 113 to 185 kilometers (70 to 115 miles) off the coast of Texas and Louisiana, Flower Garden Banks National Marine Sanctuary is one of the many marine protected areas managed by NOAA's Office of National Marine Sanctuaries.* In the warm, subtropical waters of the Gulf of Mexico, roughly 161 kilometers (100 miles) south of the Texas-Louisiana border, there lies a secret garden. East and West Flower Garden Banks, and nearby Stetson Bank, are unique underwater features festooned with colorful sponges, textured sea plants, and myriad marine life living among more than 20 species of hard corals. Arising some 137 meters (450 feet) from the depths of the Gulf are underwater mountains called salt domes, upon which the banks’ reef communities reside in waters from 16.8 to 39.6 meters (55 to 130 feet) deep.  NOAA’s Flower Garden Banks  National Marine Sanctuary protects these special marine areas, each of which  has its own set of boundaries. Discovered at the turn of the 20th  century by fishermen in search of snapper and grouper, the banks’ colorful  reefs are the northernmost in the continental United States. The closest  tropical reefs lie 644 kilometers (400 miles) away, off the coast of Tampico, just north of  Veracruz, Mexico. Marine  species observed in the sanctuary include graceful manta rays, gentle sea  turtles, agile hammerheads, and gargantuan whale sharks — not to mention the  boulder-sized brain and star corals for which the Flower Garden Banks are  famous. Due to its more northerly location and lower average temperature than that of Flower Gardens, Stetson Bank is home to smaller coral  colonies and dense arrays of large and vivid sponges. While the sanctuary is best known for fantastic coral reefs, it also hosts thriving coral habitats in deeper waters — explore these wonderful mesophotic ("twilight" zone) communities.  Visiting Your Sanctuary While  it may not be easy to reach the Sanctuary — you’ll have to travel by boat — the rewards are great for  intrepid travelers who wish to experience the wonders of its pristine offshore  reefs. Several commercial diving and fishing charter  operators take people out to the sanctuary and to nearby oil and gas platforms. Once you’ve  brushed up on proper reef etiquette,  you can: ***Dive***. The Sanctuary offers several  intermediate to advanced dive sites. Weather, wave heights, and currents are  unpredictable, so the area is not recommended for inexperienced divers. Find  out more about the challenges of  diving in the Sanctuary.
			
			***Fish***. While recreational fishing is  allowed in the Sanctuary, the Food and Drug Administration issued a fishing caution in  2008 warning that certain species may contain ciguatera toxin,  which can be harmful if ingested by people. Catch-and-release is encouraged.
            ***Share your observations***. Visitors’ trip  reports help NOAA protect the banks’ resources. Download forms from the Document  Library, and be sure to include your photos and videos.
			***Take a Virtual Tour***. Landlubbers (and those who can’t swing the trip offshore) can *take virtual tours* by visiting a nearby zoo or aquarium with a sanctuary exhibit, by watching the Sanctuary  Video Series, or by *taking a photo tour* of the reefs at East and West Flower Garden Banks.

			***Seaside Chats***: If you'd like to offer a learning opportunity for the public, please reference the sanctuary's Seaside Chats program, which takes place every February.
 Sanctuary **Series** As a travel destination, few places on the planet can compete with the diversity of the National Marine Sanctuary System.
