5 /5 Ingrid Hill: Aka Businessmans Lunch Falls. Park in the small lot for Mulholland Wild Flower Preserve and walk across the bridge, enter from opposite side of bridge. Steep, short walk to the bottom of the falls so it might not be for everyone and good footwear is a must. The powerhouse ruin at the fall is very cool. Top portion is a dam and lower section is natural falls. Running hard on May 11, 2025.
