Hike overview
Onkaparinga Gorge Hike: A Challenging Adventure for Experienced Bushwalkers. The Onkaparinga Gorge Hike is a demanding, full day or overnight adventure designed for experienced bushwalkers. This 17km, grade 5 hike traverses the entirety of Onkaparinga River National Park, a short drive south of Adelaide, following the Onkaparinga River from east to west.
Be prepared for a remote and rugged experience. The hike primarily follows the riverbed itself, with no formed or maintained paths. You'll navigate towering cliffs, serene waterholes, and ancient river red gums, encountering obstacles, water crossings, and sections without established trails. Strong navigational skills and route-finding abilities are crucial for completing this challenging trek.
Importantly, this hike is only recommended during the summer months when the water levels are low. High water can render the route inaccessible and dangerous due to difficult or impossible river crossings.
Track grade
Grade 5 (Difficult) - Walks for the Most Experienced: Grade 5 represents the most challenging walking tracks on the AWTGS. These are only recommended for very experienced and fit walkers with specialised skills, including navigation and emergency first aid. Tracks are likely to be very rough, very steep, and unmarked. Walks may be more than 20 kilometers. These challenging walks demand a high level of fitness and experience to navigate difficult terrain, significant elevation changes, and potentially unformed paths.

Just received this comment so thought I would share it here: Trail is completely missing. Had to bail out halfway. Go on this hike if you wanna kiss snakes on all fours for 8+ h, or swim the entire way.
