One of our favourite place to visit with overseas guests, the appearance of Cape Raoul beyond the road terminus in the coastal scrub is sensational. Two short paths exit the car park, one easy one to a lookout giving a much better view and good written information. The second to the cave, has many well-constructed steps; my husband (86) always goes down to the bottom viewing platform and hasn't failed to make it back again! he says there's over 100 steps.
PWS manages the area, and has wisely attempted to make access to the cave difficult for the less nimble. It is actually a natural tunnel which sometimes has sand and a calm pool within and sometimes a rocky floor with big waves rolling in.
There is a toilet at the back of the bus park/turning circle to the right as you arrive, try not to park in there as it restricts options for larger vehicles, however the major parking area is sadly in need of new paint work to define the actual parking spots.
Back up the road a few metres the track to Mount Brown and Crescent Bay is marked. This is a great walk, well marked and used, but very exposed to bad weather. Don't go up the mountain if you are not happy traversing rock slabs, the beach and backing dunes of Crescent Bay are reward enough, and at least half a day is required to complete the return walk.
