During the day, Horicon Marsh is a relaxing and tranquil place to enjoy nature. But the dark mysteries of the marsh at night can be "chilling" to those not accustomed to the sounds of nocturnal creatures. Hike leader Liz Herzmann will dispel the myths of the night as she helps you identify the many nocturnal sounds that come from within the cattails. This program will be conducted outside with easy walking but possible uneven terrain, so remember to dress warm and bring a low powered flashlight. Meet at the Horicon Marsh Education and Visitor Center, off of Hwy. 28 between Mayville and Horicon. Please use the lower entrance on the south side of the building.
