Have anyone done both diving and snorkeling in Catalina Island? Would you mind offering advice if the amount of sea creatures we see in both activities are almost similar? I do acknowledge that these two activities are different, one is close to water surface and one is waterdeep, but as diving will cost way more than snorkeling, it’d make sense to do snorkeling if what we can’t see much differences from the two activities. (I don’t have diving certification yet)
