[2] The park is located on the Gulf of Mexico in southern Jefferson County, south of Port Arthur and just west of Sabine Pass.

The park was closed for several years due to extensive damage from Hurricanes Rita (2005) and Ike (2008).

Three nearby national wildlife refuges on the Texas coast - Brazoria N.W.R., San Bernard and Big Boggy - form a vital complex of coastal wetlands harboring more than 300 bird species.

The portion of Texas State Highway 87 extending through Sea Rim to High Island is closed, having been destroyed in 1989 by Hurricane Jerry.

In September 2005, Hurricane Rita did extensive damage to Sea Rim State Park, forcing its closure.
