Top spots where local captains target swordfish and other deep sea fishing species.
Grand Isle Offshore Platforms
The offshore oil and gas platforms south of Grand Isle in 100-300 feet of water create some of the most productive artificial reef habitat in the Gulf. Yellowfin tuna, wahoo, cobia, amberjack, and red snapper hold around the platform structures in impressive numbers. Jigging and live-baiting around the rigs produces consistent offshore catches on full-day trips.
Midnight Lump (from Grand Isle)
The Midnight Lump seamount is accessible on long-range trips from Grand Isle, approximately 70 miles offshore where the ocean floor rises dramatically. Yellowfin tuna, blue marlin, wahoo, and mahi-mahi concentrate over the lump in extraordinary numbers. It is one of the premier bluewater destinations in the entire Gulf of Mexico for trophy-class pelagic fishing.
Grand Isle Lumps
A series of natural bottom features and lumps south of Grand Isle in 150-400 feet of water create concentrated feeding zones for pelagic species. Yellowfin tuna, blackfin tuna, wahoo, and mahi-mahi patrol these underwater rises, especially when current lines and weed lines converge. The lumps are a cornerstone of Grand Isle's offshore charter fleet itinerary.
South Timbalier Block
The South Timbalier lease blocks southwest of Grand Isle feature a dense concentration of platforms and underwater infrastructure in 100-200 feet of water. Red snapper, amberjack, grouper, and cobia hold on the structure, while yellowfin tuna and wahoo cruise between platforms. The area provides both excellent bottom fishing and productive trolling routes for bluewater species.
