The Catedral de San Ildefonso in Mérida, Yucatán, is one of the oldest cathedrals in the Americas, showcasing a blend of Renaissance and Moorish architectural styles. It's generally accessible to visitors, though certain areas might have limited mobility access. A solo visit allows for self-paced exploration, but a guided tour can provide deeper insights into its history and religious significance. There are no significant seasonal restrictions, but be aware of large crowds during religious holidays. Entrance is typically free, but donations are welcome. A typical visit lasts between one to two hours, depending on your level of interest and whether you take a tour. Consider visiting during off-peak hours to avoid crowds and to fully appreciate the serene atmosphere.
