An easy drive south out of Mexico City, Cuernavaca is referred to as the "City of Eternal Spring" because of it's mild climate. This destination is the capitol of Morales state and a popular retreat for harried Mexico City residents looking for rest and relaxation.
Cuernavaca has a handful of historic sights, like looming Palacio de Cortes, an old fortress, and the city cathedral, Recinto de la Catedral. Tour the home of late artist, Robert Brady, now a museum, for more architecture and an extensive art collection.
If old buildings don't shake your tree, head for the green of formal gardens at Jardin Borda or take a side trip to the waterfall, Salto de San Anton, nearby.
A number of archaeological sites are within reach of Cuernavaca though transportation of some sort is required. Find stone etchings at Chalcatzingo, sprawling ruins at partially excavated Xochicalco or stay local with the pyramids at Piramide de Teopanzolco.
If all this adventure leaves you short of relaxed, head east to Cuautla for a soak in piping hot springs.
Cuernavaca is just over an hour south of Mexico City.
