Join us at Severson Dells for these family-friendly, open-house style events. Each month will have a different nature theme full of hands-on, minds-on activities for guests of all ages to participate in. Weather permitting, there will also be guided hikes.


All Science Saturdays are FREE!


Most Science Saturdays are 10 am to 2 pm except when specified.
