Bicheno Blowhole

The blowhole is one of Bicheno's natural wonders where you can view saltwater blasts from the top of this unique geological feature. Air is blown through a small hole at the surface due to pressure differences between a closed underground system and the surface. When the seas are pumping, the blowhole puts on a spectacular display! The 80 tonne boulder next to the blowhole rocks with the tide.
