Rottnest Island is a long and narrow island, about 11 kilometers long. Rottnest Island is separated from the Australian mainland by the rising sea level. The entire coastline of Rottnest Island is full of beautiful white sand beaches. The sea is very clear and very suitable for snorkeling. Rottnest Island is a short-term holiday destination. There are 63 beautiful white sand beaches on the island, and there is no car disturbing tranquility, so it is very popular among locals. After you arrive, you can rent a bike or take a hop-on free hop-off bus. Of course you can also take a kayak to the secluded bay, snorkeling or diving in the coral reefs and ancient shipwrecks. Surfers will love the waves of Strickland Bay, Salmon Bay and Stark Bay. Want to go around and explore the hidden beaches and mysterious surf spots on the other side of the island, the best way is to rent a bicycle. Remember to look at the short-tailed kangaroo, the name of this island is inspired by this cute marsupial. The island was once an aboriginal prison and therefore has a fascinating history, including many early colonial buildings, a lighthouse and many tunnels worth exploring.
