Mountain views, raucous nightlife and a C-shaped bay with a plethora of beaches make Acapulco a more upscale, yet reasonably priced, escape than its spring-break cousin, Cancun. The city's charms are many: Pie de la Cuesta is a quiet village perfect for a moonlit stroll. Swim with dolphins and thrill on the rides at CiCi water park. And of course, watch the divers soar off the magnificent cliffs at La Quebrada. Travel in winter for a bustling nightlife and in off-season for a quieter retreat.
