Fiesta de San Juan 2026 in Guanajuato City — Presa de la Olla Celebration

The Fiesta de San Juan returns to Guanajuato City in June 2026, bringing one of the region’s oldest and most beloved traditions back to the historic Presa de la Olla. This centuries-old celebration, dating back to colonial times, honors the arrival of the summer rains and the feast day of San Juan Bautista (St. John the Baptist) on June 24.

What to Expect at the Fiesta de San Juan 2026

The celebration stretches across the second and third weeks of June, with events building toward the grand finale on June 24. The festivities center around the scenic Presa de la Olla (Olla Dam), an 18th-century reservoir that once supplied Guanajuato City with drinking water and now serves as a picturesque gathering place surrounded by the Florencio Antillón Garden.

The Opening of the Dam

The undisputed highlight of the Fiesta de San Juan is the traditional “apertura de la presa” — the opening of the dam. On June 24, hundreds of spectators gather to watch as the dam gates are opened, releasing a powerful cascade of water. This tradition traces back to a colonial-era story of a poor miner who came to the dam to give thanks for the arrival of rains, and it has become one of Guanajuato’s most iconic annual spectacles.

Music, Dance, and Cultural Events

Beyond the dam opening, the Fiesta de San Juan has evolved into a full-scale cultural celebration. Expect live music ranging from traditional banda and mariachi to contemporary genres including techno, reggaetón, duranguense, and grupero. A traditional beauty contest (certamen de belleza) adds to the festive atmosphere, and food vendors line the park offering regional specialties.
