Holy Hill State Natural Area Adventures

Holy Hill State Natural Area is a distinctive protected site located in Washington County, Wisconsin. It is centered around a prominent glacial kame rising approximately 1,350 feet above sea level, making it one of the highest points in southeastern Wisconsin. The hill's unique geological formation was shaped by the last Ice Age, creating diverse habitats consisting of oak and maple forests, grasslands, and wetlands. The natural area covers roughly 175 acres surrounding the famous Holy Hill Basilica, a Roman Catholic shrine and pilgrimage destination established in the early 20th century. Visitors to Holy Hill can enjoy a variety of outdoor activities such as hiking on well-maintained trails, birdwatching, and photography, especially from the scenic overlook atop the kame, which provides sweeping views over the Kettle Moraine and Lake Michigan on clear days. The site also has cultural significance due to the basilica’s historic architecture, stained-glass windows, and the annual events that draw pilgrims and visitors alike. The combination of natural beauty and spiritual heritage creates a unique visitor experience. The area is accessible year-round, with seasonal changes offering wildflower blooms in spring, vibrant fall foliage, and opportunities for cross-country skiing in winter. Educational signage along trails highlights the area's ecological and geological features, making it a popular destination for families, nature lovers, and history buffs alike.
