here are the maps for the mlpa
la jolla kelp is about 3/4 mile out from the la jolla shores launch
PL kelp doable from shelter depending on your stamina
if you are going to fish the point loma kelp make sure you time the tides, you want the tide going out when you are and coming in when you are and it will make it much easier
it may be easier to launch out of mission bay and hit the north PL kelp, again time the tides.
