Paseo de la Reforma is a wide avenue in the heart of Mexico City, originally designed to connect the National Palace with Chapultepec Castle during the Second Mexican Empire. Today, it's a bustling hub filled with tourist attractions, luxury restaurants, and office buildings. The avenue is known for hosting celebrations, protests, and parades, and on Sundays, it's closed to traffic for the Paseo Dominical Muévete en bici program.
