Seawolf Park is located on Galveston's Pelican Island, a former immigration station site. The park offers one of the island's most popular fishing piers, picnic sites and a playground. The park is also home to the American Undersea Warfare Center which berths the WWII submarine USS Cavalla and the only Edsall-class destroyer escort left in the US, the USS Stewart. The remains of the tanker S.S. Selma, the largest concrete ship constructed, can be seen northwest of the park's fishing pier. Come spend the day fishing, picnicking and experiencing history all in one spot—Seawolf Park!
