The Frida Kahlo Museum, Casa Azul in Coyoacán, is a compact, personal house-museum so buy a timed ticket online well in advance because slots often sell out. Arrive a little early for your entry time, expect small rooms and crowds, and allow about an hour to 90 minutes to see the studio, paintings and personal items. Photography without flash is usually allowed but large tripods and oversized bags may be restricted, and the house has stairs with limited wheelchair access so plan accordingly. Combine the visit with a stroll through Coyoacán market and a nearby café, and double-check current hours and ticketing on the museum website before you go.
