This short walk through Berowra Valley Regional Park is perfect for a daily breather. Berowra Valley Regional Park is right next door to Berowra Valley National Park. A level path takes you down to Zig-Zag Creek, over a bridge and up to the high walls and towering forest of the old railway quarry, an attractive natural amphitheatre of sandstone. Even though there's no directional signage, you'll find the path easy to follow.
You'll see fern trees, grass trees, coachwood and a variety of tall eucalypts while hearing the joyful call of kookaburras. Interpretive signs tell the history of the historic Zig-Zag railway that used to pass through here. Take a seat on the old railway sleepers and enjoy the peace and beauty of the bush before heading back to daily life.
