Has anybody ever flown into BOLA from San Joaquin Valley? Do I fly /drive to Ensanada then fly or what!.

You might try posting on the "Baja Bush Pilots" Board for a current response for conditions -

BOMBERO

Bombero has a good idea... also there is a Baja Bush Pilot member who may fly you there... Contact Capt. Mike at Screaming Airlines
Here is a bit of what is on his site: "We often go to San Carlos on the mainland, but the more memorable times are had at, Mulege, Bahia de Los Angeles, Punta Pescadero, Loreto, Punta Colorada and Punta San Francisquito (a private fly-in only destination campground and resort)."

Just FYI: Bahia de L.A.'s airport is a paved runway just north of town. No services or regular flights from any public carrier.
