we rode the bike and snorkeled around the island--Pinky and the Basin. It was a very fun experience. The weather was great and equipment was good. Service was very efficient and on time. Highly recommend this experience.
The roads in Rottnest have many uphill and downhill sections, so cycling requires a fair amount of physical strength. However, it was a great experience. We saw lots of quokkas, and the ocean was beautiful.
