Hi Ryan. Welcome to Fishing Reminder.
Looking on the map, it looks like you might be restricted mainly to piers and jetties. The first thing to do would be to check the local laws and regulations. Any tackle store should have that info. Looking at the beach area, I would be very surprised if fishing was allowed. The jetties might be public or private and might have rules for each individual one.
Looks like it might be a bit of a drive. But I would be looking at Newport Pier if fishing is allowed there.
Grabillo Beach looks perfect for a beginner. Plenty of car parking. Rock, beach and pier all short walks. Both sheltered water and direct ocean water, literally across the road from each other.
With more experience, I would definitely be hitting Point Vicente area.
The local tackle store can tell you the best bait for the area. Just remember, they might tell you the best bait they want to sell which might not be the best bait for you to catch a fish !!
Just go with the good old standard raw prawn.
I assume you will be using a standard threadline reel. (AKA eggbeater or spin). Start with a very basic rig. A single hook and a round (ball) sinker.
Use my tried and true "scientifically" proven, never fail system of selecting hook and sinker size --- "Yep, that looks about right."
A round ball sinker can fit back out of anything it falls in. Other shapes can turn and get stuck. Just pick a size "that looks about right" for the conditions. Same for the hook. A size "that looks about right" for the size of the bait and the fish you think might be in the area.
If you are using a threadline reel, there is no need for a swivel etc. You can use the very basic straight through line with running sinker. Simply slide the sinker on the line and tie on the hook.
Once you get out there, you will meet other fisher folk. Most of them are quite happy to share tips and tricks for the local area.
