South Jetty Port Aransas: Fishing, Access & Safety Guide
We've walked the South Jetty at every tide, in every season, under every wind a Texas summer can throw at it. It's 1.3 miles of granite that points east into the Gulf at the south side of the Aransas Pass ship channel — and it's the most-fished, most-photographed, most-underestimated piece of public land in Port Aransas. Here's how we get out there, what's biting, and how we keep all our ankles.

Quick answer
The Port Aransas South Jetty is 1.3 miles of granite on the south side of the Aransas Pass ship channel, at the north end of Mustang Island. Walk-on access and parking at the end of Cotter Avenue are free. It's prime year-round fishing, but a working maritime structure, so wear closed-toe shoes and watch the swell.
Where the jetty is and how to get there
The South Jetty is the rock breakwater on the south side of the Aransas Pass ship channel, where the Gulf of Mexico meets the back of Corpus Christi Bay. From the ferry landing, take Cotter Avenue east until the pavement ends at a free public lot. A short footpath drops you at the base of the jetty next to the small fishing beach.
Drive time from the ferry: about two minutes. From the JFK Causeway, roughly fifteen. No shuttle, no tram — everyone walks on. Cyclists can ride the path to the base, but the granite itself is foot-traffic only.
The contrarian take: don't start at the end
Most visitor guides push you to walk the full mile and a quarter to "fish the deep end." We'd tell you the back third gets more press than bites. The first quarter mile holds bait against the rocks on every incoming tide, the footing is honest, and we've put more keepers in the cooler from the inshore stretch than from any heroics off the tip. Walk further when conditions invite it. Don't walk further because a brochure said so.
What you can catch, by season
The jetty produces year-round because the channel flushes huge volumes of bait and saltwater past the rocks on every tide cycle. Port A seasons run a little later than the rest of the Texas coast — warmer Gulf water keeps the tropical species around past when they'd usually leave.
Spring (March–May)
Sheepshead numbers peak in March and April on shrimp and fiddler crabs. Black drum bite hard on the new and full moons. Specks start showing on top-waters at first light. Spanish mackerel arrive once the water creeps into the upper 60s.
Summer (June–August)
Tarpon roll in the channel mouth — sight-cast big swimbaits or live mullet from the rocks if you've got the gear and the patience. Jack crevalle blitz on outgoing tides; we've watched a pod of jacks crash a school of mullet ten feet off the rocks and turn the water white. Tripletail tuck next to crab traps and floating debris. Mangrove snapper hide in the deeper crevices near the middle of the jetty.
Fall (September–November)
The bull redfish run pushes 35-plus-inch breeders into the channel for spawning. Cut mullet or whole crab on the outgoing tide is the classic play, and the take is unmistakable. Trout migrate back through. Bluefish blitzes can fill a small cooler in twenty minutes flat.
Winter (December–February)
Slower, but sheepshead and black drum stay catchable on shrimp. Slot reds cruise the warm-water edges near the channel. Pick mild afternoons with light wind — a hard front shuts the bite down for a day or two on either side.
How to fish it without getting hurt
The South Jetty is a working maritime structure, not a fishing pier with rails. Every year people get pulled in by an unseen swell, slip on wet granite, or get caught flat-footed when a freighter's wake sends water over the first row of rocks.
- Wear closed-toe shoes with grip. Flip-flops on jetty rocks are how people break ankles. Old running shoes or dedicated jetty boots are the move.
- Watch ship traffic. When a tanker or container ship inbounds from the Gulf, step back from the channel edge — the wake can sweep the rocks half a minute after the ship passes.
- Never jump between rocks in surf. The gaps get deeper and wider as you walk out. A wet jump on slippery stone ends careers.
- Turn back when seas exceed 3–4 feet. The first quarter mile stays passable in most conditions; the back third becomes a wave break in any real swell.
- Bring water, sun cover, and a phone. Zero shade, zero water, and cell service goes patchy past the halfway mark. Tell someone the plan.
Gear and tactics that actually work here
The jetty rewards rigs that survive contact with granite. Heavy fluorocarbon leaders (40–60 lb), strong hooks, and a willingness to lose tackle are non-negotiable. For bait fishing, a fish-finder rig with a 3–4 oz pyramid weight holds cut bait on the bottom in current. For artificials, soft plastics on 1/4- to 1/2-oz jig heads, top-waters at dawn, gold spoons for ladyfish and Spanish.
The first hour of an incoming tide pushes bait off the flats and pins it against the rocks. The last hour of an outgoing tide concentrates everything flushing out of the bay.

Frequently asked questions
Where is the South Jetty in Port Aransas?
The South Jetty sits on the south side of the Aransas Pass ship channel, at the north end of Mustang Island. Walk-on access is at the end of Cotter Avenue — drive past the ferry landing, take a right onto Cotter, follow it to the free public lot at the jetty entrance.
Is there a fee to fish the South Jetty?
No. The South Jetty is free public access and parking is free. You'll need a Texas saltwater fishing license with a saltwater stamp if you're 17 or older — TPWD sells them online at tpwd.texas.gov.
What fish can you catch at the South Jetty?
Year-round the jetty gives up black drum, sheepshead, and ladyfish. Late spring through fall it adds redfish, speckled trout, mangrove snapper, Spanish mackerel, jack crevalle, tarpon in the heat of summer, and bull reds in the fall. Tripletail hang on the rocks in summer; bluefish and bonito blitz on outgoing tides.
How far out can you walk on the South Jetty?
Roughly 1.3 miles. The first quarter mile is easy walking on flat granite blocks. After that the rocks get larger and the gaps get wider — wear closed-toe shoes with grip, and never jump between rocks when the surf is up.
Is the South Jetty safe?
It's a working jetty in an active ship channel, not a sidewalk. The granite turns slick when wet, swells crash without warning, and ship wakes sweep the lower rocks. Stay back from the channel edge when freighters pass, never fish in lightning, and turn around when seas push past 3–4 feet.
What's the best tide for South Jetty fishing?
The first two hours of an incoming tide and the last two hours of an outgoing tide consistently beat slack water. Cross-reference our /tides page with the day's wind — moving water against a light onshore breeze is the sweet spot.
