The Spectacular Sunken Garden of Mount Gambier

Mount Gambier in South Australia has a some AMAZING  attractions, some free and some  paid. Now we haven’t seen all the good stuff that Mount Gambier and surrounds has to offer but the Umpherston Sinkhole ranks very high on the list of must visit attractions.  Mount Gambier is famous across the world for is largest sinkholes and with  sinkhole gardens located in the city of Mount Gambier they are sure not to be missed. 

About the Sunken Garden of Mount Gambier – Umpherston Sinkhole 

The Umpherston Sinkhole garden was made by James Umpherston in 1888, what was formally a limestone cave until the roof collapsed. The sinkhole is in the middle of the botanic gardens. Whilst wandering the Botanical Gardens you will find this is a great spot for a picnic or a snack with huge trees to provide plenty of shade. There is an onsite cafe available to get food and drink. 

Its a very short walk down to the sinkhole, access to the bottom is only available via the stairs. However their are viewing platforms from different areas around the top of the garden to capture some great photos.

Many people highly recommend coming at night to see the wildlife and possums who call the tranquil garden their home. We didn’t visit at night however it’s something we must do on our next trip here. 

Where to find Umpherston Sinkhole 

Travel Jubilee Highway East in Mount Gambier and you will find the signage to the Umpherston Sinkhole. Parking is pretty limited  and during peak times it can be quite difficult to get a park close by.  The sinkhole is open from dawn until dusk daily and is a free attraction for all.

Why you should visit this spectacular Cave Garden – The Important Sinkhole Facts 

This place is just beautiful, tranquil and relaxing. If your looking to update any family photography it’s a wonderful spot visit to get your new family photo!  Or if your after some time to chill out, highly recommend coming to just sit in the garden and take in all of natures beauty.  

When we visited it was Easter 2018 and School Holidays which meant people overload!  We went twice at different times of the day and it was always busy. The local Mount Gambier council is to be congratulated on having such a beautiful garden thats  free for everyone and is being consistently  maintained.

  1. I have travelled the Great Ocean Road (from Melbourne to Port Fairy) but I did not get as far as Mt Gambier. It does look like an amazing place. I love the sunken garden formed in the sinkhole.

  2. What an interesting attraction. I’ve seen sinkholes in Florida, but they always fill up with water! So cool that they created a beautiful sunken garden out of this sinkhole. The views from the top are gorgeous!

  3. Thanks for the introduction as I have never heard about this incredible place in Australia! The sunken garden is incredible and I am happy to know how people could transform it and beautifying the sinkhole. @knycx.journeying
