Catalina Island, California. I've only been there once, but it was so wonderful! The most colorful snorkeling! The late Jack LaLane (fitness buff) used to swim to Catalina from Long Beach, Calif. every year until he reached around 80 yrs. old. I would guess its about 40 miles? have to check on that...
Calico Ghost Town, California A great weekend trip with lots to see and do. Do not leave without checking out the Mystery Shack. The restaurant is great too and they do have RV parking and a few small cabins, reservations for overnight stay required,
