The Bolivar Peninsula is the long finger of land that separates East Galveston Bay from the Gulf of Mexico, with sandy beaches fringing its south side and areas of marsh on the north. It’s popular with anglers and the sun-and-fun set, but it also boasts one of Texas’s most famous birding locations: Bolivar Flats.
TX 87 runs along the peninsula, the route between High Island (UTC 51–55) and the vacation playground of Galveston Island, which encompasses nearly a dozen sites on the GTCBT. Rollover Pass (UTC 56) is the name given to a spot in the village of Gilchrist, 7 miles southwest of High Island, where a boat channel has been cut through a narrowing of the peninsula. It’s worth a quick (or long) stop anytime to check the birds that gather on the mudflats to the north of the “pass” and to scan the Gulf. Pelicans, cormorants, wading birds, shorebirds, gulls, terns, and Black Skimmers may be present in varying numbers, depending on the season, the tide, and your luck the day you visit.
