Hwy 1 - San Diego to La Paz

Much - if not most - of the main Baja road has 2 lanes about 9 feet wide. As stated above there is no shoulder - a couple feet drop off. I actually got out and measured the road. Our motorhome is 8'6" wide not counting mirrors and such. That leaves us about 3 inches on either side to play with. Semis are also 8'6" wide with mirrors. If your rig is as big as ours it can be a tense drive. Pay close attention at all times. There is almost no margin for error. Do not look at the vehicle coming at you from the other direction. Keep your head on the right side of the road and where you are relative to that drop off. If you are not as big as our Bus you have more room to play with. But this is not a road to play around on. There are also some steep hills. I am no expert as we only got about 600 miles down before we turned around. There are other roads in Mexico similar to this but on the mainland there are options. In the Baja there are no options. Some drive many miles per day on this road. For us a couple hundred miles and exhaustion sets in. Take you time and spend time seeing the sights along the way. Lots to see and do. I am no authority. We prefer the mainland. I have heard there are sections of the Baja road that have been improved since we were there but I can't provide any recent insight.
