I used to dive all the time off of Cannery Row in Monterey, CA, and also off of Pebble Beach, which is mind-blowingly beautiful when the visibility is good. Occasionally, I went diving on the Mendocino coast and Lake Tahoe. Oh wow, talk about fun! Some great times with some great people.I finally stopped diving because the was no time left between school and work. A couple of the guys had mustaches, but diving will probably be easier if clean shaven. IMHO, the great adventures and times to be had when diving make it well worth shaving off a mustache.
I took all my courses at a PADI 5-star dive shop, with the 5-star rating denoting one that is especially good. One bit of advice I would offer is learn to dive in a cold water environment if possible. My observation was that people who learned to dive in cold water enjoyed it, and also enjoyed diving in tropical waters. People who learned to dive in warm water enjoyed it, but were not overly fond of diving in cold water. I am not sure why, as the wetsuits we used kept us plenty warm. Some divers used drysuits, but it was by no means a requirement.
Ron R is right, there is not much sea life past 60 feet, although I did see huge sun stars and a marine snail down at 125 feet. The diving tables were changed after I stopped diving, and I don't think people can go down that deep on air with the new dive tables.
Man, now I miss diving a lot. Time to get the tanks hydro tested and the valves rebuilt, and then get some new equipment.
Anyways, best of luck on your diving hobby! Here is a PADI dive shop locator, in case it helps:
