Just go south along the California coast into Mexico, known as Baja California. If you drive far enough you'll reach Cabo San Lucas where the Sea of Cortez joins the Pacific Ocean right there at the end of this land strip.      Here you can go fishing for marlin, boat out to Los Arcos, a rock formation that's a resting place for sea lions and seals. If you aren't for snorkling, you can explore this lovely little resort town which has grown up into a tourist center over the last few decades.       Or shop away your spending money.
