Overview
The Poco Bayou and Big Thicket areas on the backside of San Jose Island represent some of the most remote and rewarding fly fishing on the Middle Coast. This intricate labyrinth of shallow bays, marsh cuts, and oyster lakes provides incredible protection from all but the strongest winds. The bottom is a mix of soft mud, shell, and healthy grass, supporting an abundance of baitfish and crustaceans that redfish thrive on. What makes this area special is its isolation; fewer anglers make the trip, meaning less pressure on the fish. You'll often have vast stretches of productive water entirely to yourself. Access is strictly by boat from Port Aransas or Aransas Pass. Best fished in fall, winter, and spring, though early mornings in summer can be productive before the heat sets in. Anglers should be comfortable poling a skiff or kayaking long distances and have good navigation skills, as the channels can be confusing. Be prepared for truly wild conditions.
Why it stands out
Extensive marsh system with superb wind protection
Abundant grass beds holding high numbers of redfish

Animals around Poco Bayou & Big Thicket, San Jose Island
San José Island: the coastal setting
San José Island, also called Saint Joseph Island, is a Texas Gulf Coast barrier island. It runs generally northeast–southwest, with the Gulf of Mexico to the east and south, Aransas Bay to the west, and Mesquite Bay to the north. At 21 miles long and 5 miles wide, it is a substantial coastal landscape rather than a single bayou stop. Those dimensions describe the island, not a walking or paddling route. Plan around a specific shoreline and confirmed access arrangement rather than treating the whole island as one outing. The identity and location of Poco Bayou and an island feature called Big Thicket remain unconfirmed here. Neither name should be used as a navigation target without checking a reliable local map and confirming access.
Southern and northern landmarks
Aransas Pass marks the southern end of San José Island. This is the water passage, not the mainland City of Aransas Pass. Across the passage lie Mustang Island and the town of Port Aransas. Jetties extend into the Gulf from both Mustang Island and San José Island, making the passage an important landmark for understanding the island’s southern geography. Their presence does not establish a public landing, walking route, or crossing. At the northern end, Cedar Bayou formerly separated San José Island from Matagorda Island, but it no longer runs freely between the islands. Do not build a through-paddling itinerary around an assumed open connection there. For any coastal outing, check current weather and water conditions, carry drinking water and sun protection, and establish a dependable return arrangement before setting out.
Keep Big Thicket planning separate
Big Thicket National Preserve is managed by the National Park Service, but it should not be treated as a confirmed San José Island destination or as the authority for island access. Its visitor contact is in Kountze, Texas. The preserve requires no entrance pass and charges no entrance fee. Backcountry camping, hunting, and trapping there require free permits; those rules apply to the preserve and must not be transferred to Poco Bayou or San José Island. For an island trip, first establish the exact intended location, the responsible land manager or owner, and whether the proposed landing and activity are allowed. Confirm permit requirements directly with that authority. Until those basics are settled, use the coastal landmarks below for orientation only, not as verified trailheads, boat launches, or public access points.
Route options
- Aransas Pass and the southern end
A possible area to investigate for a southern-shore outing, not a verified route. Jetties extend into the Gulf from San José Island and Mustang Island. Confirm lawful access and a specific itinerary before planning travel along the shore or onto a jetty.
- Mesquite Bay and Cedar Bayou
A northern-island planning area rather than an established paddling route. Mesquite Bay borders the island to the north, and Cedar Bayou marks its former separation from Matagorda Island. Confirm access and current water connections; do not assume a through-passage.
Sample itineraries
- San José Island coastal orientation · 1 day
Plan a daytime visit only after confirming lawful access and transport. Use the island’s geography to orient the outing: Gulf of Mexico to the east and south, Aransas Bay to the west, and Mesquite Bay to the north. Keep the route within confirmed accessible areas.
- Big Thicket National Preserve planning visit · 1 day
Treat Big Thicket National Preserve as a separate destination, not an established stop on San José Island. Start with the Big Thicket Visitor Center to confirm suitable activities and current conditions. Arrange the required permit before any backcountry camping.
