It's a fantastic, dedicated path that goes all the way to Penrith. Just a friendly piece of advice: it's completely exposed to the elements. This is awesome on a crisp winter day, but if you're riding in the summer, you'll definitely want to put on plenty of sunscreen. It'll make your ride much more enjoyable. Happy cycling!
