I have driven to costa rica many times and directed many others. first trip 1975. I don't have exact distance at my finger tips but am guessing 3000 miles, depending on route, to cr/pan. Border. I have fastest route, safest route, where to stay etc. But I'll wait to find out if you've left and what style you want to travel ($$$$). I know no more about the $ style. If you know machado family in cardiff ask for ww's phone number in palm desert. Hope I can help. By the way if you can find old mex map by aaa they use to include c. A but don' think they do anymore,but check. Also cheap mex insurance in san diego or on line with "discover baja" 1800 727 2252 or possibly security south 800 9369639 (old #)
Try www.traffic.com it will give you distances, time it takes to travel, and directions. Hope this will help.
Go to goggle maps and type in where you leaving from and your destination ,it will tell you how to get there and how long it should take and how many km it will be,or get a boat and go down the coast ,drive the whole way along the coast I bet you run into panama .
Www.mapquest.com can provide you with directions to a location and even from it. Also, it can help you route stops along the way. You would type in the address in California as your "from" location and then type the address in Panama as your "to" location. It will route it usually as the fastest time as a default. You can change that option on the left hand side.
