First time at Point Lobos. First of all, have a great time!
Get to the Whalers Cove parking lot and take the stairs up to the bluff and look over the cove and the sand channel to get a picture in your mind.
All entries and exits are done at the boat ramp.
1st dive: Gear up and enter at the ramp. Surface swim out to about the middle of the sand channel. Descend there and you will be arounf 30 fsw. Swim out the sand channel on the left side of the channel. Follow that for a while. The terrain on youor left will go from smaller boulders up to where it will turn into a bit of a wall. Keep going and it will make about a 30 degree turn to the left, then another 30 degree turn to the left shortly after. Keep looking to the left and you will see "Hole in the Wall". You will be in about 60 fsw. Go past HITW and make a left around the wall. You can go back and see the other side... Now make about a 140 heading and work your way back in toward the cove and the sand channel. The kelp is not thick now but if it was, you would really want to get all the way back to the channel at least.
2nd dive. Enter at the boat ramp and again surface swim out to about half way through the channel. Take a 30 degree heading and descend. Follow that 30 degree heading until you either make it over to the other side of middle reef or your turn pressure, whichever comes first. Then take the reciprocol path back to the sand channel. Max depth 45 - 50 fsw.
That should provide you with two fine dive plans for your first two dives at Lobos.
Before your dives, go take a look at the relief map they have in front of the restrooms and visualize your dive plans.
Once again, have a great time!
