South Padre Island
LTC 034

This site is open for day use only.

From Port Isabel, continue east on TX 100 across the Queen Isabella Causeway to South Padre Island (SPI). Once on the Island, go north on Park Road (PR) 100/ SPI Boulevard to the end of the pavement and the undeveloped portion of South Padre Island. The beach is accessible at Beach Access #6, and at low tide a four-wheel drive vehicle may continue north to the Mansfield Cut. This stretch of beach has produced a number of rare gulls, terns, and pelagic species. Peregrine Falcons are common in winter and migration, and shorebirds such as Snowy and Piping Plovers are easy to find feeding along the water's edge.

SPI Convention Centre / Laguna Madre Nature Trail
LTC 035

This site is open for day use only.

Return south on PR 100 to Orca Circle and the SPI Convention Centre. Begin by walking around the convention center's native gardens. During migration these plantings can harbor impressive numbers of migrating birds. As you pass the south side of the convention center, be sure to enjoy The Whaling Wall #53, painted on the convention center by noted artist Wyland.

Continue to the Laguna Madre Nature Trail boardwalk that extends from the parking lot of the convention center to the Laguna Madre. The marsh here grades from fresh to salt and is an excellent place to see all of the regularly occurring rails. Virginia Rail and Sora winter in this marsh, and Clapper Rail is resident. Depending on the season, watch for Marsh Wren (year round), Swamp Sparrow (winter), and Least Bittern (summer).

SPI Gateway Project
LTC 037

This site is open for day use only.

Continue south on PR 100 to the Queen Isabella Causeway. The City of South Padre Island has constructed a trail to access the mangroves and tidal flats at the base of the causeway. This paved walkway traverses the flats on the south side of the causeway, curves under it, then crosses the flats on the north side to connect with a sidewalk system that continues north on the island. Shorebirds, gulls, and terns roost on these flats, making this trail system an excellent opportunity to study these birds. Parking is available in the cross street between the east and west bound lanes of the causeway approach by the statue of Padre Ballí. The exotic plantings in the median can also teem with migrants during spring and fall.
