Mount Schank offers a challenging and rewarding walk south-east of Mount Gambier towards Port Macdonnell.

The challenge is ascending 100 metres' elevation quickly and the reward is stunning 360-degree views from the rim of the dormant volcano.

According to Wikipedia, Mount Schank was sighted by James Grant on 3 December 1800 and named after Admiral John Schank, designer of Grant's ship, HMS Lady Nelson.

It's part of Australia's youngest volcanic field and last erupted about 5000 years ago. It has a basic ash cone and the base of the crater does not extend below the water table, so there is no crater lake, like those at Mount Gambier. Scientists believe the volcanoes could erupt again.

The 2.66km walk starts with a steep climb up steps that were carved from local limestone. It's about 1.7km around the crater rim before descending by the same route.

Most of the rim walk is relatively flat and easy, but some sections towards the end (walking clockwise) are steeper, narrow and rocky.

Views are impeded somewhat by trees, but in a few places you can see miles towards the ocean and across farmland.

I tried to don hiking boots this morning, but my arthritis wouldn't allow me, and the last part was tricky in soft shoes.

I was happy though to complete the walk 15 minutes quicker than the official guide predicts, and stopping many times for photos.

There is a short, very steep side walk into the crater itself, but it's not officially maintained and I didn't want to risk it with unsuitable footwear.

I had been to Mount Schank once before but had little memory of it, and thoroughly enjoyed today's adventure.

There's a carpark and toilets at the base of the walk. Entry is free and open all year.
