I'll be coming back with my bike, but the cafe here serves fantastic coffee and cabinet food. So even if you're just visiting the lookout this is the place to stop and enjoy a brew with a view.

Beautiful Park and a Great Hike～I started hiking Flatirons in the 1990's when I moved to Boulder. It's a beautiful spot and a solid hike with some good climbs and elevation changes. Back in the spring of 1998, a friend was visiting from the midwest. We went for a hike in the flatirons and came across a fresh mountain lion kill - a doe mule deer. I'm sure we were being watched in return.

Best view of Boulder from above with a nice scenic overlook spot. And it only takes 10 minutes to get there from town.
