There's a great hot springs place just south of Mexicali that is quite remote.
We made it in a 72 bus, so a Syncro should be no problem.  Check out
our trip info at:

You may want to book ahead if you go on a weekend...and bring warm
clothes for the evening.  The desert gets quite cold at night.

After the hot springs, take the dirt road south of San Felipe but go
off the main track, about 50-100 metres off the main track is a "dune
buggy" trail most of the way....it's way more fun than the main road.

Make sure you stop at CoCo's corner, he'll sell you a cold beer and
you can sign his guest book.
If you look in his book around Jan 8, 2003 you'll see a drawing of
the bus we had at the time.

After CoCo's corner you can get back to the main highway, then go to
Bahia de Los Angeles for some nice beach camping.  Hopefully the road
is paved smoothly all the way now...back in 2003 it was paved
washboard for the last 20k or so...

Another fun "off road" section is the coast east of Cabo San
Lucas/San Jose Del Cabo.

Make sure you gas up whenever you can, gas can be hard to find in
some parts of Baja.

When going to/from Baja, you can cross the border inland near Tecate
and avoid the Tijuana crazyness.  Camp at Potrero County Park on the
US side.  After primitive camping in Baja it was really nice to have
a hot shower in a clean, well maintained place.
