Janelle and I have been visiting Baja California for years. We've driven down from San Francisco all the way down to Todos Santos, but most of the time we flew.
The problem when flying down to Todos Santos is that not there's no local airport. You have to fly for 3.5 hours to Cabos and then drive for almost two hours on a very dangerous road.
If you are lucky not to hit a cow or donkey, someone might be trying to pass a slow truck on the two lane road heading directly towards you. The multiple white crosses you see on the side of the road are evidence of this danger.
For this reason we were really happy to know Loreto had its own International airport! In addition, the flight down from Los Angeles is less than 2 hours long!
There's also a great road from the airport to downtown Loreto or to Nopolo, where our lot is located. The trip from the airport to our lot takes less than 5 minutes. And to top it off, the road is lit: a series of poles illuminates the road allowing you to drive at night (something you'd never do in Todos Santos since the risk of hitting a cow would be too high).
Many folks in Todos Santos appreciate the fact that it's a bit harder to get there: it keeps the town from becoming a new Los Cabos. But Janelle and I both work fulltime and we don't have much vacation time. Being able to get to Loreto in a few hours instead of wasting a whole day when travelling is a big plus.
Below I copy some pictures I took of the Loreto airport and some satellite photos I've created using Google Earth.
