March is one of the hottest, driest months in Cartagena, but it’s the ideal climate for a trip to this oceanfront colonial-era hub, which offers a handy two-fer as both city break and beach getaway. Squint slightly on a bougainvillea-wreathed street in the UNESCO-protected Old Town, and it’s like stepping onto the pages of a magic realist novel from Colombia’s own Gabriel Garcia Marquez. Then head for Getsemani, a once-rundown neighborhood a short ride beyond the city walls for a thriving street art scene and some of the city’s best nightlife. The Miami-like resort district of Bocagrande is the easiest place to decompress by the pool.
