Heron Haven in Omaha. Really, we had errands to run and were in the area, so it just worked out. The weather was not the greatest, but we wanted to see the changing colors of fall.
It was pretty with the fallen leaves on the trail. However, the water was drained and the birds were gone. Any water there was swampy and gross. We did not see any wildlife except for a blue jay and a couple quick squirrels.
If in the area, I would still recommend visiting Heron Haven but maybe wait until spring.
