In this stage of the Great North walk series, you’ll be walking 10km from Thornleigh through to Hornsby across the watershed.

Here are some highlights:

  • We'll start the stage 3 walk by leaving the watershed of Lane Cove River and Sydney Harbour.
  • We'll pass by the remains of an old quarry. You'll see the excavations for the zig zag railway, which transported gravel and helped build the Pacific Highway.
  • We’ll head towards the Hawkesbury and Berowra Valley National Park where we’ll travel by a wide variety of plant habitats.
  • Our journey will also take us by small creeks and streams throughout the day. Walking along the drainage basin is considered to be one of the highlights of the Great North walk series. Along the way you'll notice the ongoing human impact we're having on the environment.
  • We’ll stop for lunch at Fish Ponds before taking the 'Depression steps'. Here you'll have a steep climb before reaching our destination in Hornsby.

Bring at least 2 litres of drinking water, lunch and snacks. It's a good idea to wear enclosed shoes and bring a hat, rain gear, sunscreen, insect protection, walking poles if needed, and emergency contact information. We'll be using public transport for one section, so don't forget your Opal card.
