I live close to Laguna and ride there often. It is beautiful along the coast and in Oct., you won't have the usual tourist traffic. There is no bike lane in down town Laguna but if you ride north up the coast to Newport Beach, there is plenty of room. You can make a right at Newport Coast and go up a nice long rolling climb that will take you into Irvine or you can go along the coast all way to Seal Beach. If you go south along coast highway you will end up at San Clemente state beach, if you keep going you can go all the way to Oceanside through Camp Pendleton Marine base. It's an awesome ride, you can turn around at any time depending on how many miles you want to put in.

Hope this helps, if you need more information e-mail me.
