Giants Cave is one of the wilder show caves in the Leeuwin-Naturaliste National Park cave system. It runs for about half a kilometre and drops to a depth of 86 metres, with ladders, tight passages, and a more physical feel than the easier guided caves nearby.
It is best for visitors who want an active cave visit rather than a simple walk-through. Wear shoes with grip and allow time for the climbs and narrow sections.
