The Semaphore jetty is one of the longest in South Australia, providing a significant vantage point for observing marine life.
Semaphore beach is part of a 60-kilometer stretch of coastline known as the Gulf St Vincent.
The suburb of Semaphore was named after the maritime signalling station established there in 1849.
The beach hosts the annual Semaphore Greek Festival, one of the largest ethnic cultural events in South Australia.
The nearby dunes have been subject to extensive conservation programs to prevent erosion and preserve local coastal flora.
The Semaphore carousel is one of the few remaining historic merry-go-rounds in Australia that still functions at its original seaside location.
Semaphore Beach is a long, sandy stretch located on the LeFevre Peninsula in Adelaide, characterized by its shallow, calm waters and extensive dunes. The beach features a prominent 585-meter-long jetty, originally constructed in 1860 and rebuilt in the 1920s, which serves as a popular destination for recreational fishing. The foreshore is home to a traditional seaside carnival area and a historic merry-go-round operating since the 1920s. Visitors can access a paved esplanade that runs parallel to the coastline, connecting the beach to local parks and picnic facilities. The beach is patrolled by the Semaphore Surf Life Saving Club during the peak summer season. The surrounding suburb of Semaphore retains much of its colonial-era architecture, including various heritage-listed buildings along the main commercial strip. The area is known for its relatively gentle surf, making it a common choice for families and novice swimmers.

Explore the side streets near the beach to view well-preserved Edwardian and Victorian-era residential architecture.
Utilize the designated swimming areas patrolled by lifeguards during the summer months for maximum safety.
Do not swim outside of the patrolled areas, as rips can occur despite the calm appearance of the water.
The jetty is open year-round, while the carnival rides and carousel operate primarily on weekends and during school holiday periods.
Standard beach etiquette applies; swimming between red and yellow flags is expected.
