The tidal range on The Sanctuary exceeds 4 meters over Spring tide creating an extensive area that is inundated and then dried twice every 24 hours. Given the strength and speed of tidal flows the vistas at The Sanctuary transform with remarkable speed creating an ever-changing, horizon. This dynamic feature of The Sanctuary is also one of its dangers as visitors are prone to misreading the tides and finding themselves stranded. Awareness and caution should be exercised at all times and visitors are discouraged from venturing too far from base without a guide (skipper) with sound local knowledge of the waterways and the shoreline.
