Located in nearby Golden, this state park is an ideal spot to hike and check out the changing fall colors. It's also close to the Coors brewery. Considering the time of year, it's possible the Aspen leaves will be just beginning to turn bright gold, and this is a great location to see that.
There are a ton of great spots in this family-friendly neighborhood! We recommend New Image Brewing (that's the address listed here) and the Arvada Tavern, but there are other restaurants, coffee shops, and galleries/souvenir shops in the area as well.
