Mountain Falls

One of our most ambitious projects to date, we are thrilled to welcome the Green Mountain Falls Skyspace by James Turrell to the landscape of Green Mountain Falls, as part of the new Red Butte Recreational Area.  The Skyspace is a naked-eye observatory, where visitors view a sky through an opening in the ceiling, called an oculus.

Tickets for Skyspace Experiences through January 2023 are now available

A one-of-a-kind experiential art experience, that begins and concludes with an exhilarating hike through the Red Butte Recreational Area in Green Mountain Falls.​

a b o u t 

Cosseted on a butte overlooking Gazebo Lake and bathed by the rustling of pine trees, the Green Mountain Falls Skyspace is a harmonious addition to the charming town at the foothills of Pikes Peak—an extension of the landscape, preserved in its natural setting. The experience begins with an inspirational journey via two new trailheads that deliver hikers directly to the sheltered Skyspace on the butte above, overlooking the center of town and Gazebo Lake.

Be enveloped in a one-of-a-kind kinetic light and color encounter—a sensory and contemplative experience unlike anywhere else in the world. The Skyspace stands at 18-feet-tall and ours is one of the few in the world with a retractable roof, allowing for “closed roof” shows to occur outside of the Sunrise and Sunset experiences.  The Green Mountain Falls Skyspace was commissioned by the Historic Green Mountain Falls Foundation.  

s h o w i n g s

Skyspace is open to the public Thursdays-Sundays, and available for school field trips and other groups on Wednesdays.  The Skyspace is completely closed for maintenance on Mondays and Tuesdays.  Check the ticketing page for specific dates and times of shows open to the public.  For schools and other groups, email:

  • Sunrise Show – Approximately 45 Minutes
  • Closed Roof Shows – 20 Minutes
  • Sunset Show – Approximately 50 Minutes

Outside of these formal show times the trail system is open daily.  The Skyspace is available to visit without a ticket, in its natural state after Sunrise and before Sunset on days the Skyspace is open, unless the trail system is closed due to weather or maintenance.


1. Be prepared to arrive at the Skyspace by the time of your showing (the time marked on your reservation).  To do that, plan on arriving between 30 and 60 minutes before your scheduled reservation to provide time to hike up to the Skyspace. The hike should take between 15-30 minutes, depending on your speed.  The hike to and from the Skyspace is self-guided. Take a look at our campus map and trail map to find preferred trailheads and parking lots.

RED BUTTE RECREATIONAL AREA WEST:  Joyland/Pittman Trailhead: 

10605 Green Mountain Falls Rd., Green Mountain Falls, CO 80819


10392 El Paso Ave. Green Mountain Falls, CO 80819

2. The trails are considered a moderate to advanced hike, based on the elevation gain and the already high altitude of Green Mountain Falls (7,800 Feet). Trails are marked thoroughly.

3. We recommend wearing appropriate hiking shoes and to be prepared for inclement weather by bringing appropriate rain gear.  If you are attending a sunrise or sunset show, please note that it will be dark when you arrive for the sunrise show and dark when you leave following the sunset show.  Even though part of our trail system is lit, please bring a flashlight or headlamp.  We have flashlights available if you forget yours.

4. Stay Hydrated! Bring water.  We also have water bottle refill stations available (at the Green Box Workshop, Church in the Wildwood, and at the Town Overlook). Feel free to bring your own cushion to sit more comfortably during your showing.

5. For individuals who need support in accessing Skyspace, an ATV is available, but must be scheduled at least 48 hours before your scheduled visit when you register for showings. For those who have secured ATV transport, the ATV will pick you up at the Red Butte Recreational Area EAST Trailhead 30 minutes before the show’s scheduled start time. The ATV will be on its way if it is not there when you arrive.  Please email for more information.

6. Suggested routes depending on show times:

Closed Roof/Mid-Day Shows: Park in the Red Butte Recreational Area WEST parking lot.  You can descend the same way you came, or walk down to the EAST trailhead, and walk through town to get back to your vehicle.

Sunset showings: Park in the Red Butte Recreational Area EAST parking lot or on street parking throughout the center of Green Mountain Falls.  You can then either walk through town to the WEST trailhead and, following the show, hike down to the EAST trailhead right back to your vehicle or hike up and down the EAST trailhead.

Sunrise showings: Park in the Red Butte Recreational Area EAST parking lot. We welcome guests to hike back down the way you come up; or, hike down to the WEST trailhead and then walk back through town to your vehicle.

7. In case of bad/inclement weather, participants should expect an email and/or text message notification and signs posted at the trailhead.


NOTE:  If for any reason, we need to cancel a Skyspace show,  you will be notified via email and on the homepage of this website.

How to get to the skyspace

Our Skyspace has multiple viewing times each week, some at formal times, with other opportunities to happen upon it.  To access the Skyspace, you can find trailheads located just North of Gazebo Lake, and at the Eastern end of the Joyland parking lot.  View our campus map or the ticketing page for more information.

The hike from the center of town to the Skyspace is moderate for expeienced hikers and is between 15 and 30 minutes based on your speed.   Keep in mind that the hike includes steeper sections with an increase in altitude from the base of town which is already 7,800 feet above sea level.

 For those who are disabled and unable to hike to the Skyspace and back, a vehicle (ATV) driven by Green Box staff is available for transport.

Reservations for vehicle access are limited and must be made at least 48 hours before your scheduled visit.  Email for more information.

Skyspace FAQ's

The Skyspace is a permanent installation.

Please arrive to begin your journey between 30 and 60 minutes before your reservation time.

Our Skyspace is located on the new Red Butte Recreation Area, above the center of town.  There are two trailheads on either side of the Butte that will provide access.  The Pittman Trail, accessed via the Joyland Parking Lot is the more scenic route.  The Turrell Trail is shorter, but stepper, and is accessed behind Gazebo Lake on Ute Pass Avenue.

Base your starting point on the maps shown on the ticketing page.  

We will not allow entrance to the Skyspace during Closed Roof shows if you arrive after the lighting sequence has started.  For sunrise and sunset shows, the door to enter the Skysapce remains open, and you are welcome even if you arrive after the show has started.

The Skyspace remains open in inclement weather, but if the temperature is below 25 degrees, we will cancel showings and close the trail.  Because our Skyspace is one of the few in the world with a retractable roof, some Sunrise and Sunset shows will be replaced by closed roof shows in significant weather situations.  In any event, to get to and from the Skyspace, you will probably get wet in the event of rain.

Layered clothing, hiking shoes, flashlight/head lamp, hat/sunglasses, bottled water.  Additionally, you are welcome to bring a seat cushion and/or blanket into the Skyspace with you.   Read our Skyspace Do’s and Dont’s below for more specific information.

meet James turrell

For over half a century, the American artist James Turrell has worked directly with light and space to create artworks that engage viewers with the limits and wonder of human perception. Turrell, an avid pilot who has logged over twelve thousand hours flying, considers the sky as his studio, material and canvas. New Yorker critic Calvin Tompkins writes, “His work is not about light, or a record of light; it is light — the physical presence of light made manifest in sensory form.”
