Yes, rattlesnakes are at Catalina....and everywhere else in Arizona and a lot of the West. Millions of people live here. I see 'Scottsdale' in your Profile. They are there, too.
๐ Our grandkids live there and walk to school. They've seen rattlers on the pavement.
However, they don't travel in packs and they don't chase you down. Carry a flashlight at night; be aware of your surroundings; don't sit or put your hands anywhere that you can't check it out first.
Other than that....have fun!
