Colorado: With a network of trails to suit every level of hiker, get up-close with the Flatirons (the slanting slabs of sandstone that are Boulder’s most recognizable landmark) framed by a beautiful meadow.
James Clark: Great trail from Mapleton to the summit. It's a steep incline up, but it's short and if you need a get a good workout in within an 1 to 1.5 hours - this is it.
BoulderRunner: The small Weather Loop trail, Walter Orr Roberts Nature Trail at NCAR features a system of signs describing weather phenomena along with a great view of the foothills and of Boulder itself.

Annie Kawasaki: "The pass, as you enter Eldorado State Park and run above the stream... There are no words... I've never seen anything like it. I'm in awe."
Kimberly Gillem: great summit view. took steep climb from the 'billy goat' trail on the 1st leg - straight up! for easier route, take the valley trail.
