About The Blowhole
A natural rock chimney on the Tasman Peninsula where ocean swells surge into a sea cave below and compress air upward through a narrow hole, shooting plumes of foam and spray dramatically skyward during large seas. The blowhole is most spectacular in rough conditions when the Southern Ocean swell combines with strong onshore winds. Located just metres from Tasman Arch and Devils Kitchen on the clifftop walk at Eaglehawk Neck.
About
A natural rock chimney on the Tasman Peninsula where ocean swells surge into a sea cave below and compress air upward through a narrow hole, shooting plumes of foam and spray dramatically skyward during large seas. The blowhole is most spectacular in rough conditions when the Southern Ocean swell combines with strong onshore winds. Located just metres from Tasman Arch and Devils Kitchen on the clifftop walk at Eaglehawk Neck.
History & Significance
The Blowhole is a natural sea cave carved by wave action over thousands of years through the Tasman Peninsula's dolerite rock formations. The compressed air effect occurs when ocean swells force water into the cave, creating pressure that shoots spray skyward through a narrow chimney. It remains one of Tasmania's most spectacular coastal geological features.
