Just north of Perth is Yanchep with lagoon and national park perfect for a snack break & photo opp (possibly with friendly kangaroos)! With wetlands, birdwatching, bushwalk trails and over 400 caves to explore, you could easily spend days in Yanchep. Options to camp as well as a beautiful guesthouse are available.  

Explore the abandoned dolphin park (Atlantis Marine Park with Titan Statue) at Two Rocks as you head up the coast.
