During Landmark After Dark Night Hikes, you can go with one of our guides or walk at your own pace through the 335 acres of the Landmark's restored prairie preserve. In the cool of the day, wildlife are more active, the stars are coming out, and you can enjoy wildflowers blooming. Hikes starts 30 minutes before official sunset. Wear your closed-toes, sturdy shoes. For their own safety, pets are not allowed at the Landmark.
