Deep sea fishing in Biloxi: the run past the barrier islands, ranked

Deep sea fishing in Biloxi works a little differently from the ports on either side of it. Biloxi sits behind the Mississippi Sound and a chain of barrier islands, so the productive offshore reefs and the red snapper grounds are a real run, 20 to 45 miles out past the islands, farther than the quick hop from a port like Orange Beach. It is also a private charter town through and through: there are no head boats and no walk on seats here, so you book the whole boat for your group. The offshore fleet is smaller than the big Alabama and Florida ports, so this page ranks the Biloxi deep sea fishing charters worth booking on our published method, and names the ones it set aside and why.

The fishing is a reef and bluewater story once you clear the islands. Red snapper is the fish most trips are built around, stacked on the Gulf reefs and wrecks, and around it the boats work vermilion snapper, amberjack, triggerfish, and grouper on the bottom and king mackerel and cobia closer in. The few boats rigged for the long overnight run reach the floating rigs 80 to 120 miles out, the same blue water the Venice fleet fishes, for yellowfin tuna, wahoo, and marlin. The season to plan around is red snapper, but the rules split by boat, so it pays to read the calendar before you book.

What you catch and when

Biloxi fishes through the warmer months, and the target changes with the season and the boat’s permit. Red snapper is the prize, and the dates are worth understanding: Mississippi’s state season for private and state licensed for-hire boats opened May 22 and closed July 5, 2026, a short window, while federally permitted charter boats fish the longer federal for-hire season, June 1 to October 26, 2026, both at 2 fish per person and a 16 inch minimum. Around snapper, the reefs give up vermilion snapper, amberjack in a short federal fall window, triggerfish, and grouper. King and Spanish mackerel run the barrier islands and the nearshore from spring into October, cobia move through in spring, and the long runs to the rigs reach yellowfin tuna and wahoo in summer and fall. The seasons shift year to year, so confirm the current dates with the Mississippi DMR and NOAA Fisheries before a season specific trip.

The boats and operators

Biloxi is a private charter port with no head boat, which shapes everything about booking here: you hire the whole boat for up to six anglers, and there is no per person seat to buy. The offshore fleet runs to a type, the owner operated six pack sportfisherman or catamaran in the high 30s, comfortable enough for the long run out and back, with a couple of operators reaching further. One runs a fast Freeman catamaran built for bluewater trolling and deep dropping; another runs a 30 hour overnight trip to the rigs for tuna. A larger inshore fleet works the Mississippi Sound and the bays for trout and redfish, but that is a different kind of trip from the offshore reef and bluewater this page ranks. The fleet docks mainly at Biloxi Small Craft Harbor and Point Cadet Marina, a run out through the Sound and past the islands to the Gulf.

How the field ranks

The offshore field here is small but the boats that clear the bar are strong. At the top is Shearwater Charters at 8.1, the deepest reviewed boat in the port, a 37 foot sportfisherman owner run since 1995 with the fullest trip menu, held just off the very top by an older, slower hull. Mississippi Gulf Coast Fishing Charters is second at 7.7, the most bluewater capable operation in Biloxi with a fast Freeman catamaran and a regional best charter award, marked down because its rates page does not state what is included and the deep water trips add a fuel charge. Fish-On Charters follows at 7.6, a stable 38 foot catamaran with a deep, verified review record, dinged by an older hull and a cleaning fee that is a tip rather than included.

Below them, Biloxi Bluewater Charters at 7.5 is the family run boat with the widest range, from a reef day to a 30 hour tuna run, held back by prices that do not line up between its site and the booking platform. Mega-Bite Fishing Charters at 7.2 is the value and record pick, with the deepest review trail in the port and no fuel charge, scored at the foot of the ranked field because much of its business is inshore and its offshore trips run a rotating roster of captains. The cards below carry each boat’s verdict and score.

Trip types and what they cost

Booking in Biloxi works one way: private, by the whole boat. There is no walk on head boat here, so a solo angler or a pair pays for the whole boat, which makes Biloxi a better value for a group than for one or two. A half day or a 6 hour reef trip on a six pack runs about $850 to $1,000 for the boat, an 8 hour trip that reaches the offshore snapper grounds runs $1,350 to $1,750, and a full 10 to 12 hour day runs $1,950 to $2,500. The deep water trips cost more: an all day deep drop for grouper and tilefish or a bluewater run for tuna and swordfish reaches $2,300 and up, and a 30 hour overnight to the rigs runs about $4,000. Most boats include the rods, tackle, bait, license, and cleaning, though a couple charge a fuel surcharge or treat cleaning as a tip, so confirm what is in the price. Our cost guide breaks down what each tier buys, and the party boat versus private charter guide explains why a port with no head boat costs more for one or two anglers.

How to pick the right trip

Start with your group and your target. For the best all round offshore day with the deepest record, book Shearwater, and match the date to the red snapper season. If a steady ride matters for a group prone to seasickness on the long run, the catamarans, Fish-On and the Freeman at Mississippi Gulf Coast Fishing Charters, ride flatter than a single hull. For a serious bluewater day chasing tuna or swordfish, Mississippi Gulf Coast is the boat built for it, and for an overnight run to the rigs, Biloxi Bluewater advertises the 30 hour trip. For the best value and the deepest review record on a straightforward red snapper trip, Mega-Bite includes everything with no fuel charge. Book ahead for red snapper season, and if it is your first offshore trip, the first time guide walks you through the rest.

Getting there and what to bring

Biloxi sits right on Interstate 10, about an hour and a half from New Orleans and an hour from Mobile, with the charter harbors a short drive off the highway along Beach Boulevard. Most of the offshore fleet docks at Biloxi Small Craft Harbor by the lighthouse or at Point Cadet Marina at the east end of town, both a run out through the Mississippi Sound and past the barrier islands to the open Gulf. Because the snapper grounds are a real distance offshore, the longer trips spend more time running than at a port right on the pass, so plan for a full day and pack accordingly: sunscreen, a hat, polarized sunglasses, a soft cooler with ice for your fillets, food and drinks, and motion sickness medication if you are unsure of your stomach, since the run across the Sound and the offshore chop can both turn one. No fishing license is needed on a licensed charter here, the boat covers everyone aboard, and the crew handles your catch.

Biloxi anchors the Mississippi coast we cover, with Gulfport folding into the same fleet just to the west. The nearest ports on either side are the Alabama pair, Orange Beach and Gulf Shores, an hour east, and the Louisiana tuna port of Venice to the west, and the Gulf Coast hub lists every port we rank from Texas through the Florida Panhandle.
