Hennepin Canyon is a narrow sandstone gorge with braided streams, cascades and cliff alcoves—excellent for intimate landscape and long-exposure waterscapes. Visit spring and after rains for strongest flows; fall for vivid foliage. Best light is low-angle sunrise or soft overcast to tame highlight/shadow contrast. Trail access is moderate with some stairs; park in the small lot off IL‑71 (state park parking rules apply). Expect muddy sections and limited cell service; weekdays and early mornings/
