Strolling, shopping, and sipping tequila along the Malecon boardwalk of Puerto Vallarta is the best way to kick off your vacation. Then hit the cobblestone streets of Old Vallarta to browse the flea market for handicrafts. The calm, warm waters of the Bay of Banderas make for excellent diving, or you can just watch artists sculpt spectacular creations in the sand. And the cluster of fine art galleries in El Centro are perfect spots to hit on a self-guided art tour.
