Ok so we have been messing around with a new program that came out by California Trail Maps. Looks like they have just about every trail in San Diego and just about every off road trail as well. They have labeled every thing in San Diego, either for BLM, State, National Forest, etc… So far so Good. If you own a Garmin, we found the best way is through Base Camp. They also have great instructions as well, just pay attention. For the Price it is pretty good and compliments well with MyTopo Map-Pass Service.
