Once you reach Gibson Steps Beach – a .75 mile stretch of golden sand – you are humbled by the 230 foot tall limestone cliffs. They are enormous and majestic. In front of you is the Southern Ocean, also called the Antarctic Ocean. These waters were first navigated and chartered by Captain James Cook in the late 18th century. The waves often look mild but are treacherous for swimming. If you are energetic, you can walk along the shoreline for about a mile to reach Twelve Apostles.
