Catalina Island offers a wide range of adventurous tours, excursions and explorations that will cater to your daily dose of adrenaline. I personally did the Zip Line Eco Tour, which zig and zags you through the canyons and eucalyptus trees at speeds of around 45mph. With five different zip lines dropping from 500 feet to 600 feet above sea level you will have some of the best views of the island and marina. During your tour you will zip across three quarters of a mile, and stop at eco-stations along the way to learn about the various vegetation, wild life and history of the various geographic locations on the island. The maximum weight is 245lbs, and the cost per person is $103.
