Morialta Conservation Park to Norton Summit is the most geologically dramatic and ecologically rich trail run within 30 minutes of Adelaide's CBD, cutting through a narrow quartzite gorge, past three seasonal waterfalls, and climbing through dense Adelaide Hills bushland to the elevated plateau of Norton Summit, approximately 10 kilometres northeast of the city centre. The land was declared a National Pleasure Resort in 1915 under the National Pleasure Resorts Act 1914 and has been a public reserve ever since, making it one of South Australia's oldest continuously protected recreational landscapes and today the second most visited park in the state after Belair National Park.

The trail draws trail runners, waterfall chasers, rock climbers, and weekend bushwalkers in roughly equal measure, with a strong local community of regular runners who know every section of the gorge by feel. The run from the Morialta Falls Trailhead car park to Norton Summit and back is the signature long effort, combining the three waterfall sections with a sustained climb to the hilltop village above the gorge. The first two waterfalls are the most impressive, each cascading over sheer quartzite cliffs after rainfall, and to see the falls at their best, visiting during spring or winter when the water flow is strongest produces the most spectacular running conditions. The lower gorge section is steep, narrow, and heavily shaded, with the red and orange quartzite walls rising dramatically on both sides of the trail as it follows Fourth Creek upward. The upper sections open into drier, more exposed sclerophyll woodland before the final climb to Norton Summit Road. Koalas are regularly spotted in the gum trees along the lower gorge section, and peregrine falcons nest in the upper quartzite cliff faces above the rock climbing zones. A coffee van operates seasonally at the main car park area near the Mukanthi Nature Play Space, with Sinclair's Gully Winery in Norton Summit providing a genuinely memorable post-run destination for those who time the climb well. Summer requires a very early start as temperatures regularly exceed 40 degrees Celsius in the gorge, and the park closes entirely on Catastrophic Fire Danger days. Winter and spring are the ideal seasons: cool, lush, and with falls flowing at full volume.
