There are many fun activities you can do at Catalina Island. There is a huge building with a theater in it. You can also go on a glass bottom boat and see the different types of under water life they have at Catalina Island. They have many water sports. You can go kayaking, snorkling, and parasailing. Parasailing is when you go on a boat, get into a parachute and fly up into the air off of the boat. I suggest not parasailing if your afraid of heights. Boat tours, rafting, and scuba diving are available at the island. You can also rent a golf cart and tour the Island.They have the Mr. Wrigley's house and his memorial. There are also many historic buildings that are beautiful. There is also karyoake at one of the resteruants that is really fun. There's a bike rink there in case you are a biker. Catalina also has bike rentals. you can rent bikes and ride on their bike paths. There are also horses you can ride down trails and you can go backpacking. Santa Catalina Island has many good lakes to fish in. Walking along the beaches, lakes, and just the Island is beautiful and something to remember (especially if you have a camera to capture the memory). There are many wonderful places to eat. They also have blackberry frozen yogurt.
