Thunder Hole is a prime example of coastal erosion, shaped over thousands of years by the relentless action of ocean waves on granite. The land's post-glacial isostatic rebound also played a role in positioning this crevice to interact effectively with tidal forces. At low tide, you can observe the intricately carved cliff walls, revealing the geological history of the area.
