Blinky Beach (LH 3) is the surfing beach for the island. It is located along the northern half of 1.3 km wide Blinkenthorpe Bay, which is bounded by the northern Blinky and southern Mutton Bird points. Blinky Point is composed of basalt overlain by calcarenite, while layered basalt cliffs and slopes rise 200 m to Intermediate Hill in the south. Eroded calcarenite also lies in the surf along the central part of the beach, while a 10 m high vegetated foredune backs the entire beach. The island airport is located behind the dune, on a low sandy area that links with South Lagoon beach 550 m to the west; the two beaches linking the north and south parts of the island. The beach is reached by following the road to the northern end of the runway, where foot tracks lead up and over the foredune to the beach. The beach is 780 m long with a central 300 m long beachrock reef, which induces a salient, with more sandy seabed and bars to either side. Waves average over 1 m and break over the central reef and bar with a permanent rip against the northern Blinky Point, a second against the reef and a strong rip running south from the reef to flow out past the southern rocks. During bigger east seas the waves can pick up to a few metres and become extremely treacherous. Blinky is the beach favoured by the locals and surfers. It has a designated 50 m long bathing area at the north end, which is the best part of the beach under average conditions. read more
