Caves
Caves are natural voids in the ground and can form by solution weathering such as in kast caves, or by erosion such as sea caves, or can form at the same time as the rock such as lava tubes. Our geology tours feature caves formed in all these ways. Caves are also important sites for fossil discoveries and provided homes for our ancestors.
The following trips feature caves:
