Things to do with kids in Mount Gambier & the Limestone Coast

This lake fills a volcanic crater in Mount Gambier, and its clear water is filtered through limestone. Its colour shifts through shades of blue. Viewing platforms ring the rim, so walk or drive around and stop at a few.

Also known as the sunken garden, this sinkhole on Jubilee Highway East is reached by a steep staircase. At the bottom, plants and hanging vines fill the hollow. Hold small hands on the way down.

A guide leads you down into the dry eastern and western caves beneath Mount Gambier's streets. The tour takes 30 minutes and covers the cave's history and geology. Bookings are essential.

Mount Schank last erupted more than 4,500 years ago and is now a State Heritage Area. A signposted 900-metre walk climbs to the crater rim for a 360-degree view to the coast. Older kids can carry on around the 2km rim walk.

Mount Gambier's second crater lake has a grassy foreshore, a playground and barbecues. It's well set up for a family picnic down in the crater. Just up the road, Valley Lake Conservation Park has a nature walk.

The Wonambi Fossil Centre recreates Naracoorte as it was more than 200,000 years ago, when megafauna roamed. It shows how the caves trapped animals for over 500,000 years, leaving fossils of around 130 species. It opens 9am to 5pm, and a family ticket was $22.50 in October 2026.

This one-hour tour visits a chamber of fossils and explains the animals that once lived here. The park says it isn't always the best choice for very young children. Tours leave at 10.15am and 2.15pm and include free entry to the Wonambi Fossil Centre.

Dolomite rock colours the formations in this cliff-face cave in shades of pink and brown. A guide gives an introduction, then you stroll the large cavern at your own pace. It's one of Australia's few wheelchair-accessible caves, open 10am to 3pm, and a family ticket was $46.50 in October 2026.

Kingston SE's Big Lobster is a favourite photo stop on the drive between Melbourne and Adelaide. In town, a smooth foreshore path south of the jetty suits prams, scooters and bikes. The Kingston Lions Playground has swings, a seesaw, climbing gear and toilets.

Robe's Obelisk was built in 1852 as a beacon for passing ships and a store for rocket lifesaving gear. The coastal trail gives the best view of it and links the lighthouse and old gaol ruins to the town centre. The whole trail can take a couple of hours, so pack water and walking shoes.
