Sea Rim State Park
South of Port Arthur and west of the aforementioned McFaddin Beach, the topography changes drastically and gives way to the estuaries and beautiful protected beaches of Sea Rim State Park. It's got the best of both worlds, with fishing in the marshes and from the shore, paddling in its many inlets, plus camping options (both primitive and with sites) and several cabins. The beach itself is 5 miles long, clean and secluded. Keep your eyes peeled for driftwood, shorebirds, and the occasional alligator track. And while you're in the area, you can head over to Big Thicket National Preserve
or do the Sabine Loop drive
, if you're interested in birdwatching in one of the best locations in Texas.
