What You'll Find at Bay St. Louis Pier

Bay St. Louis Pier is a public fishing pier on the Mississippi Gulf Coast, located in the town of Bay St. Louis in Hancock County. The pier extends into the Mississippi Sound and draws both locals and visiting anglers year-round. You can fish from the pier without a boat, making it accessible for anyone with basic gear and a valid fishing license.

The pier is known for catching Spanish mackerel, king mackerel, redfish, speckled trout, and flounder depending on the season. Smaller species like mullet and catfish are also common. The structure itself — pilings, concrete, and the pier deck — creates habitat that holds fish throughout the year, though catches and species composition shift with water temperature and seasonal migrations.

Access is straightforward: the pier is open to the public during daylight hours, and there is no pier-specific fee beyond your Mississippi fishing license. The pier has benches, shade structures, and basic amenities, making it comfortable for a half-day or full-day outing. Parking is available nearby, and the town of Bay St. Louis has restaurants and shops within walking distance.

Seasons and What Bites When

Spring (March through May) is one of the strongest periods at Bay St. Louis Pier. Spanish mackerel move into the sound as water temperatures warm, and they are aggressive feeders on small shiny lures and live mullet. Redfish also become active in the shallower areas around the pier. Water clarity improves as spring progresses, which can make sight-casting for redfish possible on calm days.

Summer (June through August) shifts the bite toward speckled trout and flounder. These species move into deeper channels and around structure as the sound warms. Early morning and late afternoon are your best windows because midday heat pushes fish deeper. Live shrimp and small live baitfish work well for trout; flounder prefer larger baits or soft plastics worked slowly along the bottom.

Fall (September through November) brings another strong run of Spanish mackerel and king mackerel as they migrate through the sound. Water temperatures cool, and fish feed more consistently throughout the day. Redfish also return to shallower areas. This is often considered the most reliable season for consistent action and larger fish.

Winter (December through February) slows the bite but does not stop it. Redfish and speckled trout remain in the sound, though they concentrate in deeper holes and move less frequently. Catfish become more reliable targets. Cold fronts can shut down the bite for a day or two, but stable weather windows produce steady fishing.

Tackle, Bait, and Technique

Medium-weight spinning or conventional tackle works well for most species at Bay St. Louis Pier. A 6.5- to 7-foot spinning rod with 15- to 20-pound braided line handles Spanish mackerel, redfish, and trout without being overkill. If you expect king mackerel, step up to 30-pound line and a slightly heavier rod. Conventional reels are popular here because they handle live bait and heavier lures more smoothly than spinning reels.

Live bait is the most consistent choice. Live mullet, pinfish, and shrimp are all effective depending on what is biting. You can catch mullet and pinfish from the pier itself using a small cast net, or buy them from local bait shops in Bay St. Louis. Cut mullet and mackerel also work, especially for redfish and catfish. Bring a small cooler with ice to keep bait fresh throughout the day.

Artificial lures are productive, particularly for mackerel and redfish. Small shiny spoons (1/4 to 1/2 ounce), topwater plugs, and soft plastics in natural colors all produce. Cast near the pilings and along the edges of the pier where structure creates current breaks. Retrieve steadily for mackerel; work soft plastics slowly along the bottom for flounder and trout.

Tidal movement affects fishing success. Bay St. Louis experiences moderate tidal swings — typically 1 to 2 feet. Fish feed more actively during moving water (incoming or outgoing tide) than during slack tide. Check tide tables before you go, and plan to fish the two hours before and after tide changes for the most consistent action.

Regulations and Licensing

You must have a valid Mississippi fishing license to fish from Bay St. Louis Pier. Residents and non-residents can purchase licenses through the Mississippi Department of Wildlife, Fisheries, and Parks (MDWFP). A 3-day non-resident license is available and costs less than a full-year license, making it a practical choice if you are visiting for a short trip.

Size and bag limits vary by species. Spanish mackerel have a 15-inch minimum length and a daily bag limit of 15 fish. King mackerel are 24 inches minimum with a 2-fish daily limit. Redfish are 18 to 27 inches (slot limit) with a 5-fish daily bag. Speckled trout are 12 inches minimum with a 25-fish daily limit. Flounder are 12 inches minimum with a 10-fish daily limit. These regulations can change, so check the current MDWFP regulations before you fish.

The pier is open to the public during daylight hours. There is no specific pier-use fee, but the town of Bay St. Louis may charge for parking depending on the lot you use. Fishing is not permitted after dark, and no overnight camping or sleeping on the pier is allowed.

Getting There and What to Bring

Bay St. Louis Pier is located at the end of Beach Boulevard in downtown Bay St. Louis, about 90 miles east of New Orleans and 40 miles west of Biloxi. If you are driving from the north, take US 90 south toward the coast; follow signs for Bay St. Louis and the waterfront. Parking is available in nearby lots, and the pier is within easy walking distance of the town center.

Bring a cooler with ice, sunscreen, a hat, and polarized sunglasses. The sun reflects off the water and intensifies the glare, making sunglasses essential for spotting fish and protecting your eyes. Bring more water than you think you will need — the pier offers no shade in some sections, and the Gulf Coast heat can be intense, especially in summer. A small tackle box with hooks, leaders, and lures keeps your gear organized and accessible.

Bring a net or gaff if you plan to land larger fish. The pier deck is high enough that netting or gaffing is often necessary for redfish and mackerel. A headlamp or small flashlight is useful if you fish early morning or late afternoon. Bring a small first-aid kit for hook punctures, and wear shoes with good grip — the pier deck can be slippery when wet.

Local Conditions and What Makes This Pier Distinct

Bay St. Louis Pier sits in the Mississippi Sound, which is a shallow, productive estuary. The sound is fed by freshwater from the Pearl River and other tributaries, creating a mix of saltwater and brackish conditions. This environment supports both saltwater species like mackerel and redfish, and brackish-water species like catfish and mullet. The pier's location near the mouth of the Pearl River means you can sometimes catch species from both environments on the same day.

The pier structure itself — concrete pilings and a wooden deck — creates current breaks and habitat. Fish hold around the pilings, especially during moving tides. The deeper water on the sound side of the pier is where larger redfish and mackerel often hold, while shallower edges near the shore attract speckled trout and flounder. Learning the pier's layout and where fish hold at different tides will improve your catch rate.

Bay St. Louis has a strong fishing culture and a working waterfront. Local bait shops, restaurants, and charter boat captains are familiar with pier fishing and can offer current conditions and advice. The town is also a good base if you want to explore other nearby fishing options — the Pearl River, Lake Borgne, and other Gulf Coast piers are all within an hour's drive.
