Transportation around the island is mostly by foot or via golf cart rentals. Bike rentals are also available on the island for longer distances. Taxi services and shuttle buses are another option to travel within the Island. There's a shuttle service available from the ferry terminal to Avalon if you are arriving by boat. Prices of golf carts rentals for 2-4 passengers range from $50-100/day.
If you have more time, visit the Nature Center or Hermit Gulch Trail Camp for camping and hiking. If you have less time, remove an activity like Zip line Eco Tour or Catalina Island Museum. You can also add a scenic golf cart drive to Mount Ada to get panoramic views of the island.
