What Travellers Say
Reviews Summary
Visitors find Hell's Hole a striking natural landmark, appreciating the scenic drive through pine forests and the dramatic view from the caged platform. While the sinkhole's depth and clear green water are impressive, some find it a brief visit with limited facilities. It's particularly noted for its appeal to divers.
"During our day of exploring from Mount Gambier we decided to visit Hells Hole at Caveton, located about 20 km (roughly a 22-minute drive) from town. The drive takes you through pine forests, and once inside the reserve, clear signage points you towards the trail. There is a small car park at the trailhead, and when we visited we had the entire place to ourselves, adding to the quiet and somewhat eerie atmosphere.
The sinkhole itself is striking, approximately 45 metres wide and 25 metres deep, with a dramatic drop down to the water below. From the secure caged viewing platform, you can step out and look directly over the edge. The drop to the water is about 38 metres, and while some people might feel anxious leaning over, the structure is very sturdy and well built. The green water at the bottom contrasted with the rocky walls makes for an unusual and fascinating sight.
It’s worth noting that if there is a total fire ban, the forest reserve will be closed, and you won’t be able to access the path or site, so check ahead before planning a visit.
For those exploring the Limestone Coast region, Hells Hole is definitely worth adding to your itinerary. A unique natural feature in a peaceful forest setting."

"Great natural landmark, down the logging tracks. About 13 min walk in some incline walking, small caged platform to take photos. Can be tricky to take pics. Apparently geologists dive here?"

"The real winner here is the road to Hells hole. I was expecting to be crawling along some corrugated gravel road, not sailing along in 5th gear on a smooth and hard surface. Awesome fun driving along it and low car friendly.
The sinkhole is a short pleasant walk through a plantation, I encourage people who take issue with heights to brave stepping in the cage, its worth it."
