At the east end of the causeway on South Padre Island, on both sides of the turnaround, are tidal mudflats fringed by black mangrove and some regionally uncommon saltmarsh cordgrass marshes. Some of the most accessible, and largest, black mangroves we know of. A boardwalk into the mangroves, on both sides of the causeway, was built with TxDOT funds, as part of the Island Gateway Beach-To-Bay Alternative Transportation Loop.
Shorebirds, gulls, and terns roost on these flats, making this trail system an excellent opportunity to study these birds.
