Sebastian Inlet, Inlet in Sebastian Inlet State Park, Florida, United States

Sebastian Inlet is a channel cut through the barrier island between the Indian River Lagoon and the Atlantic Ocean, in Sebastian Inlet State Park off State Road A1A, 12 miles north of Vero Beach. A long, low jetty of dark rock topped by a level deck on closely spaced pilings runs out into open water, with a sandy shore and rocky embankment in the foreground.

The 1715 Spanish Treasure Fleet wrecked here; the survivors' camp site was listed on the U.S. National Register of Historic Places on August 12, 1970. Settlers led by David Peter Gibson first tried to cut an inlet in 1872, and his Gibson's Cut appears on an 1880–81 survey map. Later attempts followed in 1891, 1897, 1899 and 1901, all unsuccessful.

The 1715 Spanish Treasure Fleet wrecked here; the survivors' camp site was listed on the U.S. National Register of Historic Places on August 12, 1970, as the Spanish Fleet Survivors and Salvors Camp Site. The McLarty Treasure Museum, part of the state park, displays artifacts from the wrecks.

The location is accessible year-round with parking areas and marked zones for fishing and surfing activities. It is wise to arrive early in the day, especially on weekends, to find calmer conditions.

The inlet is managed by the Sebastian Inlet District, whose five commissioners are elected non-partisan from Brevard and Indian River counties and earn an annual salary of $3,600. The district grew out of the repeated failed attempts to cut a channel through the barrier island.
