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

The Victoria Hotel Melbourne

10/10 Excellent

"Staff were very helpful "

The Langham, Melbourne

10/10 Excellent

"One of the most gorgeous, beautiful and luxury hotels I've ever been to. The first thing that hits you when you walk in the great smell of a flowery scent in the air. Then the veautiful palace like stairs and fountains. The staff are supper friendly and helpfull. The bar and their Malba restaurant were fantastic with so many options and varieties. For sure try their chicken club sandwich!"
