Flatirons Vista Trail: Hike Review

You are currently viewing Flatirons Vista Trail: Hike Review

The Flatirons are immediately recognizable conglomeratic sandstone rocks formed as part of the Fountain Formation nearly 300 million years ago. Somewhere between 35-80 millions years ago, these formations began to uplift and tilt into the rugged appearance that make the Flatirons unique. Indeed, the Flatirons are so iconic, they even appear on Boulder’s official city seal! An ideal way to enjoy the Flatirons is via the Flatirons Vista Traila fairly straightforward and relatively easy 3.5 mile loop hike only a short distance from Denver and downtown Boulder.

Unbelievably picturesque views of the Flatirons and expansive meadows teeming with ground nesting birds (e.g., Western MeadowlarkHorned LarkVesper SparrowKilldeer) make the Flatiron Vista Trail a popular year-round trail. Because the trail is multi-use, you’ll often share the loop with hikers, trail runners, mountain bikers, and equestrians. Enjoy the Flatirons!

Route Instructions

  • Step 1 - Park at the Flatirons Vista Trailhead, located off of CO-93. If you don’t have a Boulder Open Space and Mountain Parks annual parking permit, there is a self-pay station at the entrance ($5.00, cash fee).
  • Step 2 - Enter through the cattle guard gate at the trailhead and begin the Flatirons Vista Trail via the recommended counter-clockwise direction. Note that the Prairie Vista Trail also begins here, so be sure to bear right onto the Flatirons Vista Trail.
  • Step 3 - The trail will parallel with CO-93 for a few hundred feet. You’ll pass a connector trail on your righthand side that starts from the Greenbelt Plateau Trailhead. Bear left to stay on the trail towards the Flatirons.
  • Step 4 - You’ll again meet an intersection with the Prairie Vista Trail on your left. Stay on the Flatirons Vista Trail (north), which slightly inclines and continues towards the Flatirons. Beautiful meadow views will be to your left and right. These meadows are filled with an abundance of prairie dogs and ground nesting birds.
  • Step 5 - After about another mile, you will reach the junction with the Doudy Draw Trail. Continue on the Flatirons Vista Trail (south) by bearing slightly to the left.
  • Step 6 - The trail enters a ponderosa pine forested section for about a half mile. The majority of this loop is open meadow, so the shade here during the hot days of summer offers an opportunity for a rest.
  • Step 7 - As you round the loop in towards the end of the forested section, be sure to check out the views of the meadows and Flatirons to your righthand side.
  • Step 8 - The trail opens back to meadows with the occasional ponderosa pine. In the springtime, this area is filled with wildflowers.
  • Step 9 - You’ll eventually reach a cattle guard gate (one of a few on this hike) and you’ll start to head back towards CO-93 and the trailhead parking area.
  • Step 10 - You’ll reach another junction with the Prairie Vista Trail on your left. Continue along the Flatirons Vista Trail.
  • Step 11 - The meadow starts to open even further with less ponderosa trees on both sides. Don’t forget to turn around and look back towards the Flatirons every now and then for a different viewing perspective.
  • Step 12 - The trail passes a pond to the left side and again crosses the Prairie Vista Trail. At this intersection, turn right towards the parking area.
  • Step 13 - End the hike back at the Flatirons Vista Trailhead parking area. Enjoy the rest of the day and reminisce about the fantastic Flatirons views!

From Denver, take US-6 W/6th Ave. towards Golden. The road eventually turns into CO-93 N. Continue straight on CO-93 N for about 12 miles and the Flatirons Vista Trailhead parking area will be on the left, marked with an “Open Space & Mountain Parks” sign.

A daily parking permit is $5.00 (cash, exact change) and can be purchased at the fee station near the trailhead.

Recommended books

We recommend picking up a few naturalist guides for general awareness of Colorado geology, plants, and local wildlife. Particularly because the Flatirons Vista Trail has an abundance of ground nesting birds and it is common to see other wildlife during an outing, an easy to use field guide will help identify species and further add to the enjoyment of your outdoors experience.
