About Guadalajara

Jalisco's capital spreads across a highland basin, with the twin-towered cathedral and the Hospicio Cabañas anchoring the historic core. Tlaquepaque is the craft-and-ceramics district, while the town of Tequila and its surrounding agave fields make an easy day trip. January through March brings dry, mild days that suit long walks and outdoor evenings; the same months are the coolest stretch before the spring heat builds.
