Umpherston Sinkhole, Mount Gambier

(800+ reviews on the web)
Geologic Formation Nature / Park
Once a limestone cave, Umpherston Sinkhole was created when the cave ceiling collapsed. The sunken earth proved a perfect place for growing lush greenery. Thick vines cascade over the sinkhole's edge while the center is landscaped with grasses and palms. Take a walk through the garden for an otherworldly look beneath the green curtains and between the limestone rocks.

  • We took our interstate family here for some local sightseeing..& it is gorgeous! Free entry with a cafe on site..A must see for Mr Gambier!  more »
  • Take some fruit and feed the friendly possums. Best to go at night for this so bring a torch. BBQ facilities are good so you can pack a picnic etc.  more »
  • Beautiful gardens in this sink hole with ivy growing down the perimeter. Careful of the bees as there are a few around and a warning sign. There are quite a few steps down to the bottom but easily man...  more »

  • WAS a nice geological formarion. However the concrete steps/path.. the BBQ (!!!) and the platform in its center make this natural formation NOT natural anymore.
  • Beautiful gardens mixed with natural science and geology. Nature showing off!
  • Definitely worth a visit if you are in Mt Gambier or passing through. Beautifully manicured gardens in a large sink hole just of the main highway. Lovely gardens and some old logging machinery for the kids to climb on. Lots of steps so mobility is important if you want to descend.
  • Go at dusk and see the Brushtail Possums come to feed from visitors. Lovely cave, just wish there was wheelchair access because the man I supported was unable to see what I was so fortunate to see in past visits. Sadly it seems to be the norm in Mt Gambier because he wasn't able to get to see the Blue Lake from lift or other caves either apart from Tantanoola which is the only accessible cave etc in the area. Sad because the area misses out in so many visitors who would love to see it all
  • Well maintained... Easy to get down the bottom of the sink hole... Saw a possum.... Just beautiful
