The mineral spring, consecrated in honor of the apostle Andrew the First-Called, is located in the Vyshkinskaya Pristan forest, not far from the village of Undory in the Ulyanovsk district, about a kilometer northeast of the Lenin sanatorium. A bathing area has been arranged at the holy spring, where the water has a murky reddish tint due to high iron content. The bathing area is equipped with two separate entrances and a common immersion pool. Both the baptismal font and the spring itself were consecrated by Father Andrey, the rector of the Church of the Resurrection of Christ in Undory.
