Newbie to hiking

As the title says it im new to this, if you had to start from the beginning how would you go about it now that you know?

I got the gear for it for the most part and am aware of the things needed to be "safe" I can mentally and physically do anywhere from 10 miles and under looking at strictly day hikes atm.

The trouble is finding the logistics such as the actual hike, hours, the trail, the parking, etc. Basically, getting out there and what that looks like.

Side note: If you can recommend any groups would be helpful to (socal area).

Thanks in advance.
