Lighthouse Cove, Aransas National Wildlife Refuge
Texas, USA

Lighthouse Cove, nestled within the Aransas National Wildlife Refuge, is arguably one of the most iconic and productive redfish flats on the Texas Middle Coast. It’s a vast, shallow expanse of hard sand and shell, peppered with isolated grass beds, that offers exceptional sight-casting opportunities. The cove's sheer size and relative protection from strong winds, especially from the east and southeast, make it a consistent producer. Redfish here are often found tailing in the skinny water during low light or cruising the edges of the deeper channels and potholes. Access is primarily by boat, with the nearest launch points being in Port O'Connor or Rockport. The refuge's wild nature means fewer boat wakes and a more pristine fishing experience. Ideal seasons are fall through spring when water temperatures are cooler, and fish are more active in the shallows. Anglers should have moderate casting skills to handle the occasional wind and present flies accurately to wary fish. While often productive, its popularity means you might share the water with a few other boats, especially on prime weather days. **Highlights** * Expansive hard sand and shell bottom for easy wading * Consistent tailing redfish action in fall/winter * Diverse structure including potholes, grass beds, and guts * Opportunities for large bull reds on outgoing tides * Relatively clear water on calm days for excellent sight-casting **Watch-outs** * Boat access only, requiring a skiff or bay boat * Strong winds can make poling and casting challenging * Mosquitoes can be severe in warmer months * Occasional encounters with alligators, especially in back lakes

Texas, USA

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. **Highlights** * Extensive marsh system with superb wind protection * Abundant grass beds holding high numbers of redfish * True wilderness experience with minimal angling pressure * Opportunities for 'in-your-face' shots at tailing fish * Excellent birdwatching and wildlife viewing **Watch-outs** * Requires good navigational skills; easy to get lost * Soft mud bottoms in some areas can be challenging to wade * No services or amenities; pack everything in and out * Mosquitoes and biting flies can be relentless in warm weather
