Lima, founded by Francisco Pizarro in 1535, is a fascinating city and a treasure trove of history. Explore ancient Incan archaeological sites, or stroll through the elegant cathedrals and opulent palaces dating from Spanish colonial times. Downtown Lima is crowded, but you'll enjoy exploring the city's neighbourhoods—especially the beachfront areas, which have great shopping and dining and fabulous hotels.

Trujillo is a lively intersection of ancient culture and modern arts. See ancient ruins at the Chan Chan archaeological site and be awed by the Moche Huaca del Sol y la Luna (temples of the sun and moon.). The multicolored Tunnel of Wishes on the Paseo de Aguas is a fabulous place for people-watching. Locally brewed corn beer is worth a try. If you’re a nightlife lover, pace yourself—bars and clubs get going late, and then go all night.

San Pedro is "La Isla Bonita" that Madonna made famous. Now it's a tourist mecca, but still boasts great beaches and plenty of dive shops so you can enjoy the sun, sand, and sea. Plan a side trip to Caye Caulker while you're here; it is less developed and more laid back, and has its own splendid swimming areas.
