The spot

Community-maintained

Community contribution: submitted by Daniel

Tucked between rolling green hills and sheer cliff faces on the Fleurieu Peninsula, Second Valley is a stunning coastal gem about 90 minutes south of Adelaide. The sheltered sandy beach gives way to rocky headlands, a historic jetty, and dramatic underwater caves and swim-throughs. The main draw is Lasseter's Reef, a thriving bommie 400 m offshore teeming with fish. Closer in, the boulder-strewn western shoreline, seagrass meadows, and a large cave entrance offer endless exploration for confident snorkellers. Conditions here are exposed to wind and swell, so pick a calm day for the best visibility and safety.

Know before you go

Logged by the community, confirmed by mods

  • Moderate risk: Strong currents around the point

    Moderate to strong currents can develop around the rocky headland to the left of the jetty, especially on outgoing tides. Swim near the turn of tide for safest conditions.

  • Moderate risk: Swell and wind exposure

    This is an exposed site; southerly and westerly winds produce dangerous conditions. Best snorkelled when wind is under 15 km/h from the east or north, with swell under 1 m.

  • Moderate risk: Long swim to Lasseter's Reef

    The best reef is approximately 400 m offshore. Only strong, fit swimmers should attempt this swim. Fatigue can be a serious hazard on the return leg.

  • Moderate risk: Strong Currents

    Tidal currents can be strong around the point and on the swim to Lasseter's Reef. Best snorkeled at slack tide or on minimal tidal movement.

  • Moderate risk: Swell and Exposed Conditions

    Second Valley faces north and is exposed to wind and swell. Southerly or westerly winds create poor visibility and dangerous conditions. Best when wind is under 15 km/h and swell under 1 m.

  • Moderate risk: Strong tidal currents

    Moderate to strong currents can develop around the rocky point and jetty, especially on outgoing tides.

  • Moderate risk: Fishing lines and hooks

    The jetty is heavily used by anglers; submerged fishing line and hooks pose an entanglement risk.

  • Moderate risk: Southerly/westerly swell

    Exposed to southerly and westerly winds which can quickly reduce visibility and create challenging conditions.

  • Low risk: Sharp rocks at entry points

    The path over the rocks to the left of the jetty requires reef shoes. Bare feet risk cuts from sharp oyster-encrusted boulders.

  • Low risk: Cold water temperatures

    Water temperature ranges only 17–22 °C year-round. Hypothermia risk without a wetsuit, even in summer.

  • Low risk: Fishing Lines at Jetty

    The jetty is popular with fishers; submerged fishing lines and tackle pose entanglement hazards for snorkelers.

  • Low risk: Cold Water Temperature

    Water temperatures range from 17–22°C year-round. Even in summer a wetsuit is recommended to avoid cold exposure.

  • Low risk: Rocky Entry Points

    The path to the left of the jetty involves traversing jagged rocks to reach the water. Reef shoes essential.

  • Low risk: Sharp rocks

    Entry from the rocky path left of the jetty requires reef shoes; rocks are sharp and slippery.
