  • I was surprised to see such a huge area of wild life to be very close to downtown of Denver. It's great place for relaxing, may be also good for observing the sunsets. There are many deer and...  more »
  • Really liked this place! We just followed the driving trail, didn't get out of the car until the end to stretch our legs and read the information board that leads down to one of the fishing lakes...  more »
  • This was an unexpected surprise during our trip to Colorado. The site's history is fascinating, and the return to its natural state is a gift. A brief walk on a hot day (like the first day we visited) gives a whole new appreciation for what it took for early settlers to cross the Plains. The staff at the Visitor's Center was very helpful and informative. It was well worth our time to drive the wildlife route through the park. We saw the best wildlife activity when we returned during the early evening. The bison came within a few feet of our car, close enough to hear them chewing and the sound of their hoofs as they walked. When three of the larger bison started walking directly toward our car after we'd been watching them for about 10 minutes, we got the distinct feeling they were telling us it was time to move on. So we did. But its a memory we will long cherish.
  • A huge area in the metropolitan area with lots of bison, deer, cottontail, coyote, and birds. It is free. There are some beautiful lakes with trails around them. Fishing is allowed there. In addition, there is a more than 10 mile long drive in the wild area, and you are advised to stay in vehicle. Sometimes the animals are very close, please stay safe while taking pictures. Also you can take nice pictures of the rocky mountains during sunset.
