Port Clinton is the first settlement on the eastern side of Yorke Peninsula. It is spread along 1.5 km of low energy sandy shoreline and 1 km wide tidal flats. The shore is divided into three beach areas by boundary mangroves and two small forelands. The northern beach is 800 m long and extends north from a small sandy foreland formed in lee of a patch of mangroves, as a series of recurved spits that terminate at mangrove covered tidal flats.

The main beach runs south of the foreland for 700 m to a small protruding upland creek mouth. This beach is backed by the caravan park and foreshore reserve and is the main beach used for launching boats across the beach and for wading and swimming when the tide is high enough.

On the south side of the creek is the southern beach, which runs for 800 m, with about 20 shacks backing the southern half of the beach. The beach terminates at a mangroves covered tidal flats backed by 10 m high red bluffs which dominate the coast to the south.

All beaches are 24h off leash
