Footwear for Cobblestone Streets

San Miguel de Allende's charming streets are paved with cobblestones, which can be uneven and slippery, especially when wet. Prioritize comfort and stability in your footwear. Sturdy walking shoes, sneakers with good grip, or low-heeled boots are highly recommended. Avoid high heels or shoes with smooth soles that offer little traction. Our own experiences suggest that well-worn, comfortable shoes will be your most valuable asset.

Adapting to Altitude

San Miguel de Allende is situated at a high altitude (over 6,000 feet). This means the sun's rays are more intense, and the air is thinner. It’s advisable to pack sunscreen with a high SPF, a wide-brimmed hat, and sunglasses. Stay well-hydrated, as altitude can affect individuals differently. Some people experience mild altitude sickness, so taking it easy on your first day and avoiding excessive alcohol can be beneficial. The altitude also contributes to the cooler evenings and mornings, even during warmer months.
