A great circuit walk, Nancy's Peak traverses the main peak of the Porongurup Ranges 23 kilometres from Mt Barker in the Great Southern region. The difficult 5.5 kilometre Top Trail features a range of ecosystems and the views across to the Stirling Ranges and Southern Ocean are magnificent. Commencing from the Porongurup car park, the trail passes by the 'Tree in the Rock' before climbing to the top of the mountain's ridge. On the way, the trail passes through different ecosystems such as karri forest and moist glades of mosses. Emerging from the forest on the granite outcrops you will see the views to the Stirling Ranges and Southern Ocean. Across the outcrops, the trail continues over a few peaks before descending into a pass between Nancy's Peak and Devils Slide. Once on the main track between the two, it is a fairly simple karri forest ramble back to the car park.
