Port Aransas is not Galveston. It is not a barrier island sitting across a vast bay system fed by river outflow. Port Aransas, Port A, to everyone who fishes it, is a narrow town perched on the northern tip of Mustang Island, directly on top of Aransas Pass, the deep tidal cut that connects the Gulf of Mexico to Corpus Christi Bay, Redfish Bay, and the Aransas Bay complex behind it. That pass is the engine that drives everything here. Billions of gallons of water surge through the jetties with every tide change, carrying baitfish, shrimp, and crabs in and out. Predators stack up along the granite walls to intercept them. It is one of the most concentrated zones of fish activity on the entire Texas coast, and much of it is accessible from shore.
Officially designated the "Fishing Capital of Texas" in 2025, Port A puts world-class jetty fishing, a lighted Gulf pier, shallow-water flats teeming with redfish and trout, and offshore blue water all within a few minutes of each other. Every style of fishing is beginner-friendly here, and every style fishes differently from what you will find up the coast. If you have already read how to fish Galveston, you know the wade-fishing-and-bay-system approach. Port A is more about structure, the jetties, the pier pilings, the channel edges, and the oyster-laced flats of Redfish Bay.

Understanding the Port Aransas System
Before you rig a rod, it helps to know the geography, because the layout of this place dictates where and how you fish.
Mustang Island is a long, narrow barrier island running roughly north-south. The town of Port Aransas sits at the northern tip, right where Aransas Pass cuts between Mustang Island and San Jose Island to the north. Two massive granite jetties, the South Jetty on the Mustang Island side and the North Jetty on the San Jose Island side, guard the pass entrance. The South Jetty extends over 5,000 feet into the Gulf and is the most productive shore-fishing spot on the Texas coast.
Behind the jetties, the ship channel runs through the heart of Port A, past the ferry landing, past the marinas, and into the bay system. To the west, Redfish Bay sprawls out in a maze of shallow grass flats, oyster reefs, and spoil islands. The Lydia Ann Channel curves southwest through the marshes, connecting Aransas Pass to the Intracoastal Waterway. Charlie's Pasture, a nature preserve on the bay side of town, holds a lighted fishing pier along the shipping channel.
On the Gulf side, Mustang Island's beach stretches for miles to the south, with the Horace Caldwell Pier rising from the sand at IB Magee Beach Park. Beyond the beach, five miles of undeveloped Mustang Island State Park coastline offers solitude and surf fishing.
Each of these environments fishes differently and rewards different gear and technique. That is what this guide covers.
Jetty Fishing: Port A's Defining Experience
If you fish Port Aransas and skip the jetties, you have missed the point. The South Jetty is where the action concentrates, thousands of feet of stacked granite boulders that create a maze of crevices, pools, and current breaks where baitfish hide and gamefish ambush. The tidal flow through the pass pushes water along both sides of the jetty, creating eddies behind the larger rocks that hold fish all day long.
Getting to the Jetties
The South Jetty is accessible by foot from the parking area at the tip of Mustang Island, near the end of South Jetty Road. Parking fills early on weekends and holidays, arrive before sunrise if you want a spot during peak season. The rocks are uneven, sometimes slippery with algae, and waves can wash over the lower sections unexpectedly. Wear shoes with aggressive grip, old hiking boots, rock-fishing shoes, or at minimum sturdy sneakers. Do not wear flip-flops. Move deliberately and never turn your back on the Gulf side.
The North Jetty, on San Jose Island, is reachable only by boat. The Jetty Boat ferry service runs from Fisherman's Wharf in Port Aransas and drops you at the North Jetty, where the fishing pressure is dramatically lighter and the beaches are uncrowded. It is worth the trip if you want more space.
Jetty Gear
The rocks demand tougher tackle than bay fishing. You are fighting fish plus structure, a hooked redfish will dive straight into the granite and break you off if your gear is too light.
- Rod: 7- to 7.5-foot medium-heavy spinning rod with a 4000-size reel. A Penn Fierce IV 4000 combo or Penn Battle III 4000 combo gives you the backbone to horse fish away from the rocks.
- Line: 20- to 30-pound braided line (PowerPro or Sufix 832) with a 25- to 30-pound fluorocarbon leader (Seaguar Red Label).
- Extra supplies: Bring double the terminal tackle you think you need. You will lose rigs to the rocks. Pre-tie a dozen leaders with hooks at home. Carry a long-handled landing net, you cannot lift fish straight up from between the boulders. A five-gallon bucket with a rope works for lowering your catch into a safe crevice while you keep fishing.
Jetty Species and Rigs
Redfish (Year-Round, Bull Reds Best September Through November)
Redfish hold in the deeper, calmer pools behind the larger boulders, especially on the channel side of the jetty where the tidal current creates slack pockets. Slot-sized reds (20 to 28 inches) cruise the rocks throughout the year. In fall, bull redfish, fish over 28 inches, running 30 to 45 inches, push into the jetties in schools during the annual mullet run.
For slot reds, rig a Carolina rig, 1/2-ounce egg sinker, bead, barrel swivel, and 18 inches of 25-pound fluorocarbon to a 3/0 circle hook. Bait with a live shrimp or a chunk of fresh-cut mullet. Drop it tight to the rocks on the channel side and let the current work the bait into the eddies.
For bull reds in fall, go heavier, 1-ounce egg sinker, 30-pound leader, 5/0 or 6/0 circle hook with a whole fresh-cut mullet head or a large chunk of mullet body. Cast along the channel side and let it sit. When the rod loads up, reel tight and keep steady pressure. Bull reds are catch-and-release only in Texas (over 28 inches), so handle carefully and release quickly.
For artificials, a 1/4-ounce gold Johnson Silver Minnow (spoon) cast along the rocks and retrieved with a steady wobble is deadly on redfish. Bounce a Berkley Gulp Shrimp in New Penny on a 1/4-ounce jighead along the bottom near the rocks for a slower, more finesse approach.
Port Aransas Jetty Fishing: Catching Redfish on SpoonsSheepshead (Year-Round, Best Winter Through Spring)
Sheepshead swarm the jetty rocks, feeding on the barnacles and small crabs clinging to the granite. These striped, hard-mouthed fish are the most reliable catch on the South Jetty, and some of the best eating in the Gulf.
Use a Carolina rig with a 1/2-ounce egg sinker, 12 inches of 20-pound fluorocarbon, and a #1 or #2 J-hook (sheepshead have small, bony mouths, use a sharp J-hook, not a circle hook). Bait with peeled fresh shrimp or a small piece of fiddler crab. Drop it right against the rocks, within inches of the structure. You will feel a series of rapid, light taps as the sheepshead nibbles. Wait for a solid pull-down, then set the hook sharply. They are master bait stealers, so check and rebait frequently.
Speckled Trout (Spring, Fall, and Winter)
Trout hold along the channel edges of the jetty where the tidal current pushes baitfish through. They are more predictable here than in open water, the current concentrates them. A popping cork rig with 3 feet of 20-pound fluorocarbon leader to a 1/0 circle hook baited with live shrimp works well. Pop the cork in the current seams where fast water meets slack water. Trout also hit MirrOlure Catch 2000 or Catch 5 suspending twitchbaits fished along the rocks.
Tarpon (May Through September)
Tarpon roll through the pass in summer, following the schools of mullet and menhaden that pour through the jetties on outgoing tides. These are big fish, 80 to 150 pounds, and hooking one from the jetty rocks is a serious fight on serious terrain. Use a heavier setup: a 7-foot heavy spinning rod with a 6000-size reel, 50-pound braid, and 60-pound fluorocarbon leader to a 6/0 circle hook. Free-line a live mullet into the current on the channel side. When a tarpon takes, let it run before engaging the drag. This is advanced jetty fishing, but seeing a silver king launch from the water at sunset against the jetty backdrop is a sight that keeps people coming back to Port A for decades.
The Best Way to Easily Catch Fish on the Jetties, Port AransasHorace Caldwell Pier: The Easiest Entry Point
If the jetties feel intimidating, and they should, if you are honest about climbing wet granite boulders, the Horace Caldwell Pier is the most beginner-friendly fishing spot in Port Aransas. This 1,240-foot lighted pier stretches from IB Magee Beach Park directly into the Gulf, putting you over deep enough water to reach species that surf anglers cannot.
Access and Fees
The pier is open 24 hours. Admission is $3 per adult, plus $4 per pole if you bring your own equipment (or $25 per rental pole that includes the rod fee). Children under six are free. Seniors 65 and older, active military, and veterans pay $1 admission. Cash only. The on-site bait shop sells fresh and frozen bait, basic tackle, and rents rods. Fish cleaning stations are available at the base of the pier.
What You Will Catch
The Caldwell Pier produces a remarkable variety of fish. On any given day you might catch:
- Redfish and black drum around the pilings on Carolina rigs with shrimp or cut bait
- Speckled trout on popping corks with live shrimp, especially during morning and evening tide changes
- Sheepshead tight to the pilings from November through March, same rig as the jetties
- Spanish mackerel from April through October on fast-retrieved silver spoons or Gotcha plugs
- King mackerel in summer and fall, free-line a live cigar minnow or threadfin herring on a wire leader
- Pompano during spring and fall migrations on small dropper rigs with shrimp or sand fleas
- Whiting year-round on bottom rigs, excellent eating and steady action for beginners
- Sharks, blacktip and bonnethead sharks cruise under the pier regularly, especially in summer
- Tarpon, from May through September, tarpon roll near the surface under the pier lights at night
Best beginner rig for the pier: A simple bottom rig, 1-ounce pyramid sinker at the terminal end, a dropper loop tied 12 inches above it with a #2 or 1/0 circle hook baited with fresh shrimp. Drop it to the bottom near the pilings and wait. This catches whiting, sand trout, croaker, black drum, and redfish all day. When the rod tip starts bouncing, reel tight and the circle hook does the work.
Fishing Port Aransas Jetties, Easy Rig SetupBay Fishing: Redfish Bay and the Back Lakes
The bay system behind Port Aransas is where the flats fishing lives, and it is a completely different experience from the structure-heavy jetties and pier. Redfish Bay is a sprawling expanse of shallow grass flats, oyster reefs, and spoil islands that holds outstanding populations of redfish, speckled trout, black drum, and flounder. The Lydia Ann Channel, connecting Aransas Pass to the Intracoastal Waterway, runs through deeper water bordered by grass flats that average 18 to 24 inches deep, perfect sight-casting territory on higher tides.
Wade Fishing the Flats
You can wade fish Redfish Bay from several access points. The grass flats along the bay side of Mustang Island offer firm sand-and-shell bottom in many areas. On higher tides, redfish push onto the shallow flats to feed, and you can sight-cast to tailing reds as they root through the grass, the distinctive bronze fork of a redfish tail waving above the surface is unmistakable once you have seen it.
Wade fishing gear: Use the same 7-foot medium-action spinning setup from the pier section, a 3000-size reel with 15- to 20-pound braid and a 20-pound fluorocarbon leader. For wade fishing specifically, add a wading belt with pliers, a stringer, and a bait pouch. Wear old sneakers, neoprene wading boots, or dedicated wading shoes, never go barefoot. Redfish Bay has oyster shell that will slice your feet and stingrays that bury in the sand. Shuffle your feet with every step.
The popping cork rig is the go-to wade fishing setup in Redfish Bay, just as it is in Galveston's West Bay. Thread your mainline through a weighted popping cork (the Cajun Thunder is the Texas standard), then tie 2.5 to 3 feet of 20-pound fluorocarbon to a 1/0 circle hook or 1/8-ounce jighead. Bait with a live shrimp hooked under the horn, or use a Bass Assassin Sea Shad in Chicken on a Chain color or a Berkley Gulp Shrimp in New Penny. Cast near grass edges, over oyster reefs, or along drop-offs. Pop the cork, let it sit, pop again. When the cork disappears, set the hook.
Topwater at dawn: When conditions are right, calm, overcast, low light, throw a MirrOlure She Dog or Heddon Super Spook over the grass flats. Walk the dog across the surface with a steady twitch rhythm. Speckled trout and redfish explode on topwaters in Redfish Bay during spring and fall, and the explosion of a five-pound trout on a topwater plug at first light in two feet of water is a sound you will not forget.
Kayak Fishing
The shallow grass flats around Port Aransas are ideal kayak water, 1 to 3 feet deep in many areas, inaccessible to power boats but perfect for a paddle-in approach. The Lydia Ann Lighthouse area has a 9-mile network of marked kayak trails through salt-marsh flats with blue, yellow, and red loop options ranging from one to four hours. Kayak anglers sight-cast to tailing redfish and black drum on these flats with extraordinary success because the fish see almost zero boat traffic.
Charlie's Pasture Pier
Charlie's Pasture is a nature preserve on the bay side of Port Aransas with a fishing pier along the shipping channel. This is a free, lighted pier with views of the Lydia Ann Channel, you can fish for redfish, black drum, and trout while watching shrimp boats and cargo vessels pass through. It is less crowded than the Caldwell Pier and fishes well on tide changes when the channel current pushes bait past the pilings.
Surf Fishing: Mustang Island Beachfront
The Gulf-facing beach on Mustang Island runs for miles south of Port Aransas, and surf fishing here produces a different mix of species than the jetties or bay. The beach is accessible by vehicle with a parking permit ($12, available at convenience stores and the Port Aransas Welcome Center), which means you can drive to a stretch of sand, set up your rods, and fish in relative solitude, especially if you head south toward Mustang Island State Park, which offers five miles of undeveloped coastline.
Surf Gear and Rigs
Use a fish-finder rig: thread your mainline through a 2- to 4-ounce pyramid sinker, add a bead, tie to a barrel swivel, and attach 18 to 24 inches of 30-pound fluorocarbon leader to a 3/0 circle hook. A 9- to 10-foot medium-heavy rod with a 5000- or 6000-size reel handles the casting distance needed to reach the sandbars. The Penn Spinfisher VI 6500 on a 10-foot surf rod is the standard Texas surf setup.
Species from the Mustang Island surf: Whiting (the most reliable surf catch, steady action, excellent eating), pompano (spring and fall runs), black drum, redfish, jack crevalle, and sharks (blacktip sharks are common in summer).
Catch More Fish on the Beach, Texas Surf Fishing Port AransasBait and Tackle
Live shrimp are the universal Port Aransas bait. They catch redfish, trout, sheepshead, black drum, flounder, and pompano. Available at bait shops throughout town.
Live mullet are the premier bait for tarpon on the jetties and bull redfish anywhere. Smaller finger mullet work under a popping cork for trout and redfish.
Cut mullet is cheap, available everywhere, and the standard bait for bull redfish on the jetties and sharks in the surf.
Artificial lures: A Berkley Gulp Shrimp in New Penny on a 1/8-ounce jighead covers most situations. A gold Johnson Silver Minnow (1/4-ounce spoon) is the redfish killer on the jetties and flats. Bass Assassin Sea Shads in Chicken on a Chain are the standard soft plastics for trout and redfish.
Where to buy: Port A Outfitters, Island Tackle of Port Aransas on Station Street, and Harbor City Bait Shop in Aransas Pass.
Practical Details
Fishing license: Texas requires a saltwater fishing license for anyone 17 and older. Resident annual: $35. Non-resident annual: $63. A one-day all-water license costs $11 residents, $16 non-residents. Purchase at the TPWD website, Academy Sports, Walmart, or local bait shops. Charters cover all passengers.
Charter costs: Half-day inshore: ~$465 for two anglers. Offshore shared trips: $200-300 per person. Private offshore: $1,200+. For beginners, a half-day inshore charter on Redfish Bay is the best investment.
Pier fees: Horace Caldwell Pier: $3 admission + $4 per pole (cash only). Rod rental $25. Open 24 hours.
Best times: Early morning and late afternoon for all inshore species. Fish the first hour of incoming or outgoing tide on the jetties. Night fishing under pier lights is excellent in summer.
A Beginner's First Day: The Plan
Morning (6 AM to 10 AM): South Jetty at first light. Carolina rig with live shrimp or a gold spoon along the channel-side rocks for redfish and sheepshead.
Midday (11 AM to 2 PM): Horace Caldwell Pier. Bottom-fish with fresh shrimp for whiting, drum, and whatever is feeding around the pilings.
Afternoon (3 PM to sunset): Charlie's Pasture pier on the bay side, or head south to Mustang Island State Park for surf fishing. Either gives you a third fishing environment and a different species mix.
