See Rottnest Island from the water on this day trip that includes a 1.5-hour high-speed adventure wildlife boat ride. Travel to the island, a favorite local getaway due to its secluded beaches and relaxing environment, by high-speed ferry from Perth or Fremantle. Then embark on a adventure thrill ride to look for seals, dolphins, sea birds and other marine life. Afterward, you have free time on the island to explore independently; perhaps rent a bike or go swimming off one of the white-sand beaches. When booking, you may upgrade to include lunch, if you wish.
