Experience the advent of evening through the wooded trails of Severson Dells. Awaken your senses to the sounds and scents of twilight. With the sun setting shortly after six o’clock, our eyes become gradually accustomed to the darkening night. (Save your flashlight for emergency use.) Free program; all ages are welcome. Please register in advance so that we can be prepared for the turnout; use the form below or call us at 815-335-2915.
