This 2m kidney shaped lava blister was formed millions of years ago and is very rare. Originally, it was a bubble of magma but the curved roof collapsed.

There is an informative sign near the blister which has more information. #localgem

Top City of Hobsons Bay Hotel Reviews

Stamford Plaza Melbourne

10/10 Excellent

"Very happy with my stay :) "

Next Hotel Melbourne, Curio Collection by Hilton

10/10 Excellent

"This is the quietest hotel I have ever stayed in. Every aspect of the hotel was designed for comfort and efficiency. The food was good especially the breakfast however the oysters in the Restaurant were overpriced for the tiny morsels we received"

Great Southern Hotel Melbourne

10/10 Excellent

"The hotel exceeded my expectation, check-in was easy, they even had the electronic checkin. The room was nice, the bathroom very clean, the hotel as a whole was clean and tidy. And really limited noise in my room. I didn’t have the breakfast in the end but they advertised some really reasonably priced breakfasts. I was attending something at convention centre and it was so convenient.. I would well recommend. "
