apart from the amazing pinnacles desert, nambung national park is also known for its beautiful beaches at kangaroo point and hangover bay, coastal dune systems and low heathland rich in flowering plants. at the park's northern end near the town of cervantes, there is a loop trail and boardwalk at lake thetis where you can see some fascinating thrombolites (rock-like structures similar to stromatolites built by micro-organisms too small for the human eye to see).
