Make sure your insurance will cover dirt roads. Some of them only cover paved roads and there are very few of them. A place to visit is Punta la Gringa, North on Bay of LA. Excellent clams there. You will go right by the turtle conservation center. Stop, donate. For a remote experience, go out to any of the Seven Sisters. A long drive, but worth it. Good surf. If you are REALLY, and I mean REALLY adventurous, go to Mission Santa Maria, East of Catavenia. You will need a high clearance 4x4 and a willingness to go for it. Possibly the worst dirt/rock road I have ever been on. Nasty, but worth it. Pools of water with palm trees will greet you if you make it. Punta Baja has great beaches to drive on, nobody there, the birdlife is outstanding. Good surf. Cabo San Quintin has excellent beach camping. If you can make it ALL the way out, it gets better. Tons of Pismo clams are there at low tide. Go to Sierra San Pedro Martir and the observatory, about 60 miles East of Punta Colonet. If you have the time, climb Picacho del Diablo, the highest peak in Baja, 10,000+. Good luck finding the trail, but it is worth the experience even if you don't make it. All of the above advise is excellent, smile, behave, respect the locals, help them if you can, relax and enjoy whatever the trip and life throws at you.
2005 Reg Cab Dodge Diesel 4x4 6sp, far, far from stock. Gutted 4 wheel camper pop up, now a shell that rests on the bed rails. Rebuilt the interior, much simpler, far more user friendly. Much better.
