Mainz bleibt Mainz | Mainz stays Mainz
Mainz Cathedral, a thousand-year-old red sandstone giant, dominates the old town's market square. The Gutenberg Museum is essential for anyone curious about how books happened. Riesling country starts at the city limits: the Rheingau and Rheinhessen wine regions are walkable from town. Come in February for Fastnacht, when Mainz transforms into a six-day costumed party rivaling Cologne's.
Carnival week (late February or early March) packs the old town with drunk crowds, fun if you're in, miserable if you're not. Hot summer days can feel sticky in the Rhine valley. Sunday closures are strict. Plan grocery stops for Saturday. A route through Mainz should follow the practical checks, not precede them. For Mainz, a nearby substitute is useful when closures, holidays, traffic, or transit interfere.
