I am green with envy. We did Baja last year and couldn't make it down this year due to a project I have going that I couldn't leave.
Just South of you is a great beach camping spot you should check out. Turn off at the small town of Ligui and there is a great little beach where you can camp free and there is an eclectic group of travelers that hangs out there. We spent 3 or 4 days there last year. Turn off at the town and follow the road to the East. The road will fork at a wash and you want to the left.
The beach just to south of the camping area is a paradise for anyone collecting shells. I had a hard time getting my wife to leave it. You can reach this beach by hiking trail along the access road. If you go there is an older couple that stays at the South end of the Beach all winter "Keith and Betty" he is great and has been traveling to the area for many years and is a wealth of information. You may also see a rolling resort (large plush RV) with a Jeep Rubicon, their names are Bob & Liz and they are great people. The leave the RV and explore all over Baja either by Zodiak or Jeep. He will definetley know of trails less traveled. Anyway if you stop and meet any of them say Hi from John & Dana.
Also on the way back if you stop at Bahia De Concepcion I would recommend venturing inland to Ray's Place. It is a restaurant just inland (about 2 miles) from Mulege that is run by a Cuba/American named Ray. The food is really incredible and Ray is an amazing host. He also has a small campground by the restaurant if you want to escape the wind along the beach.
