Cartagena City Tour, Cartagena

Cartagena, abounding as it is with cobbled streets lined by colonial homes with bougainvilia-draped balconies, is a city that begs to be explored on foot. And a guided walking tour of the UNESCO World Heritage walled city (Old Town) is the perfect way to do this. It's a brisk 2.5-hour tour that nonetheless covers Cartagena's most iconic Spanish colonial sites.

An English-speaking guide leads the way through Old Town, pointing out landmarks and recounting the city's rich history along the way. The tour includes visits to Cartagena's extensive fortifications, like the famous ramparts that encircle the Old Town, as well as imposing fortresses like the Castillo San Felipe de Barajas. There are also visits to the city's famous plazas, like the Plaza de San Pedro Claver, with its Andalusian-style cathedral.
