Situated in Lower Glenelg National Park amidst the depths of the pine forest is Hells Hole - a circular sinkhole filled with magnificently deep blue hued water. Enthusiastic divers take to the waters of Hell's Hole to discover what lays insides the wet cave. True to it's name, this must visit destination is often reported to have an eerie ambience on a still day. Permits must be obtained to dive into Hells Hole Sinkhole, but if you're happy to admire, the viewing platform is your safest option.
