Yallingup Caves
The Yallingup area has some of the thickest limestone of the Leeuwin
Naturaliste Ridge, but despite this very few large caves or extensive systems
have been found, probably because there are very few streams to allow for the
development of large systems.
6.0.2. Yallingup Cave YA 1
Yallingup Cave itself is well worth a visit. It is currently a tourist cave. A
palaeontological dig was carried out in this cave over a period of five years
by a member of WASG. The formation in this cave is excellent and there are
several sections to visit. It is the largest cave system known in the Yallingup
area and a new extension was recently found in this cave ! A short walk from
this cave leads to Yallingup Gorge. This is a karst feature worth visiting as
there are several caves in the area, YA 12 and YA 29 being two of them.
Driving from Yallingup to Bunker Bay, one can visit a number of interesting sea
caves and other karst features. One of these sea caves is YA 14, a cave which
is developed in medium grained granulite, beach conglomerate and aeolian
calcarenite. It also has a hole in the roof in which one can see the bedding
planes.
6.0.3. Northcote Grotto
On the way south along Caves Road, Northcote Grotto can be visited. In this
cave a stream can be seen flowing in the lower sections, this being only one of
two caves in the area in which a stream is visible.
