The cliffs are at Coral Bay, which is sadly having more people visit all the time, there is even a fucken five star hotel and a marina meant to be happening. At the moment though it is still possible to access the coast and drive north on the tracks around the northwest cape. This takes you up to Yardie Creek and then to Exmouth.
On the gulf side it is a lot more sheltered - generally - and you watch the dark rise rather than the sun set. The bottom of the gulf and up the north eastern side is mostly mangrove trees and mud.
The whole of the northwest has some fucken huge tides, which means some really strong currents. Fuck swimming in it though - there are also heaps of sharks (these flicks are north of Shark Bay - that kind of says it all). There are also heaps of sea snakes, extremely venomous but they apparently have small mouths - unfortunately some are really big, 2-3 meters, and they - to my thinking - would have corresponding sized mouths.
The tidal volume is so large in some places that there are "horizontal waterfalls" and one place where the water rushes through a chasm - I think that I heard somewhere that this particular movement of water is the volume of eight Sydney harbours - through the chasm - twice a day. Pretty speccy.
