@tonyexpress and
@cheryl , (or anyone!) ever been to Catalina Island? Anything I shouldn't miss?
When I was growing up my parents had a boat so we went to Catalina for the weekend many many times.
When you're walking down the pier to the town to the left of the pier there is a beach. There was a popular restaurant/bar on the main street. The Casino is a beautiful art deco building to the right down the main street. If you like that kind of architecture it's definitely worth touring.
If you like to snorkel we used to see a lot of Garibaldi while snorkeling there. The water was a little cold for me so I always had to wear a wet suit.
We also used to rent bikes and explore the streets. There were also golf carts for rent.
The back side of the island was pretty much wilderness that had campgrounds and areas with wild buffalo.
I haven't been to Catalina for many years tho so there is probably different stuff to do now.
