Stupendously beautiful. So beautiful it was overwhelming. In addition to beauty of the gardens designed inside the sinkhole by the Umpherston family, the stairs leading down to the sinkhole had been designed to make it easy even for the least mobile among the crowd. You could walk down at your own pace and rest at intervals and there was plenty of garden seats on the lower levels. It was hard to imagine that this was once the remnants of a volcanic explosion. We would recommend this to all those who visit Mt Gambier. In addition, there were no fees involved.

I had read about the Umpherston Sinkhole so when we were passing by we stopped and had a look. It’s an amazing park and in the rear is this huge sinkhole which you can walk down into via a set of stairs. There is a lovely garden in the centre and I just love the thick lush vines which cover most of the limestone cliff walls. Lookout for a very cute possum who someone feeds that roams around in one of the overhangs. A great place to spend half an hour or so. Worth reading about the geological as well as the history of the sinkhole usage.

Have never seen anything like this before and it was spectacular. Only a few kms out of town you find this sinkhole which is now a sunken garden. There is parking but when busy can be tricky to park. There is some local history around to explain how the sinkhole came to be. You have great views from up the top and then it changes completely as you start to descend and walk around. There are some areas you can only see from a distance due to safety but it is well worth the walk down. Once at the bottom you look up and realise just how unique it really is. There are toilets on site and it did promote a gift shop and cafe as well but it was not open when we were there

We enjoyed visiting Umpherston Sinkhole which as been developed into a very unusual garden feature. There are significant falls of ivy on the walls, two huge palm trees in the middle. A fascinating visit and worth making time to see.

Wow this was my favourite out of all the sinkholes. What an amazing job to make this a beautiful area to just sit and take it all in. The sinkhole is huge and it has been turned into a magnificent garden where you can walk around or just sit and relax amongst all the amazing plants and trees. Well worth a visit to this sinkhole.

The Umpherston Sinkhole is one of those sites you should never miss, a quirk of natural limestone erosion and a scene to behold thereafter. If you're in Mount Gambier, definitely take a moment or two to learn about this place. Who knows, another sink hole might swallow you up along with the city :) This is a free attraction and does require a degree of exercise, if you want to walk to the very bottom of what I call the Hydrangea garden. Or you could be semi-lazy and rest after a small descent and photograph everything from on high. Like the Blue Lake before it, this is worth a detour if for no other reason than to look at a wonderful garden and a big Sinkhole.

If you visit one place in Mount gambier it should be this spot. A local icon that I remember from my childhood 25 years ago. Amazing spot that is so unique. Come back at night to see the possums
