Cabo San Lucas is an anchor port for all cruises sailing on Mexico's Riviera and Sea of Cortez itineraries, but passengers are a small minority of the tourists who flock there. The heavily Americanized party town serves as one of the most popular beach escapes for Californians and other West Coasters who come here to let loose (spring break festivities are intense and not a proposition for the faint of heart). One of Cabo's major attractions is Cabo Wabo, a cantina owned by rocker Sammy Hagar. Rocks of a different sort -- El Arco, with its jagged points protruding from the Sea of Cortez, make more impressive photos. Yet for those passing on the beer-pong tournaments and temporary tattoos, Cabo has a lot to offer. Located at the southern tip of the Baja Peninsula, Cabo San Lucas -- together with its more elegant and much quieter sister town of San Jose del Cabo -- is an ideal spot for adventure-oriented pursuits. If conditions are right, the clear waters make for great snorkeling kayaking, stand-up paddleboarding, parasailing, sailing and jet skiing. The Sea of Cortez is among the biologically richest areas in the world, with pods of whales that winter offshore; if you're here in season (late December through late March), a whale-watching trip is a must.
