Piles Creek loop
If you’re looking for a hike with a chance to unwind afterwards, head to Girrakool for Piles Creek loop. Wandering through dry eucalypt forest, this day walk follows the deep gorge of Piles Creek past waterfalls and scenic clearings, so make sure you bring your camera. It even crosses a suspension bridge and reaches the Illoura lookout, with stellar views over the forest canopy, which offers a good opportunity for birdwatching.
At Illoura, the trail also crosses the Girrakool loop for a longer walk that takes in a fascinating Aboriginal site with carvings in Hawkesbury sandstone. Eventually, all roads lead back to the large grassy Girrakool picnic area, where you might like to fire up the free gas barbecues for a lazy afternoon in the shade of eucalypts.
