Lost Canyon Ranch Open Space: I Hiked Every Open Trail. Here's the Guide.

Castle Rock opened Lost Canyon Ranch Open Space to the public on Monday, July 13, 2026, and it's the largest piece of open space the Town has ever bought. I went out and hiked all the open trails over two days.

The basics

Lost Canyon Ranch Open Space is 681 acres on the southeast edge of town, pressed up against Castlewood Canyon State Park. There are 10 miles of trail open right now, with another 5 under construction. The finished network will be 15 miles.

The ground runs from rolling grassland to mature mixed coniferous forest to hoodoo rock formations and dramatic canyon cliffs, all of it wrapped around the wide Lost Canyon, carved out by Willow Creek as it cuts through the property. It's open now, but the work isn't done: parts of it are still an active construction site, so yield to the crews.

Read this before you drive out there

No dogs. No horses. No pets of any kind, anywhere on the property. This is a ban, not a leash rule. If you show up with your dog, you're turning around. Take them to Castlewood Canyon State Park next door instead, where leashed dogs and service animals are welcome.

A few more things, and they aren't boilerplate:

• There's no drinking water on site. Bring more than you think you need. I hiked in the heat both days, around 85 degrees, and most of these trails have little shade.
• Cell service is limited, and the paper trail maps at the trailhead can run out (they were all gone one of the days I went). Pick your route before you lose signal.
• Rattlesnakes are active out here. That's the Town's warning, and I'm not just repeating a sign: I've seen rattlesnakes on this property myself.
• Bikes are allowed on the roadways only, never on the trails. Park them at the racks at either trailhead.
• Portable restrooms are at both trailheads. Cattleman's has a hand-wash station; Creekside has only hand sanitizer.

The trails, easiest to hardest

On the Town's map, the trails are color-coded loops linked by shorter connectors. The Town rates most of them moderate to difficult, and only calls out Pronghorn and Willow Creek as easy. Distances below are the Town's official numbers. Elevation is my own, measured on an Apple Watch. I haven't seen it published anywhere else, but if you have better numbers, let me know.

One thing to know before the list. There are only two parking lots, Creekside and Cattleman's, but several trails don't start at either one. You reach them by walking a connector trail first, and a few of those connectors are the hardest part of the whole outing. The pull up to Turkey Track gains about 82 feet in a quarter mile. The one up to Gobbler's gains about 112 feet in 0.4 mile. The high ground around Golden Eagle and the Big Bear overlook sits roughly 170 feet above the lot. The loops themselves are easy to moderate once you're on them; the work is often just getting to them.

Trail	Distance	Elevation gain	Difficulty (Town)	Difficulty (me)	Shade
Pronghorn Path	0.6 mi	~30 ft	Easy	Easy	None
Willow Creek Path	short, flat	~36 ft	Easy	Easy	A little
Echoes of Ancestors	0.8 mi	~117 ft	Moderate	Easy	A little
Turkey Track Loop	0.6 mi	~38 ft	Moderate	Moderate	Some
Gobbler's Pass	1.1 mi	~111 ft	Moderate	Moderate	Some
Lost Moccasin	0.8 mi	~170 ft	Difficult	Hard	Some
Big Bear Hollow	1.7 mi	~190 ft	Difficult	Hard	Some
Bootlegger's Loop	2.6 mi	~300 ft	Difficult	Hard	Some

I sorted by how hard each trail actually feels, not by the elevation number, so a gradual 117 feet like Echoes lands easier than a short, steep pull. Below is each one, in the order I would send you.

Pronghorn Path, the easy one at Cattleman's

The flattest, simplest walk out here, 0.6 miles. A short crusher-fines loop right at Cattleman's Trailhead, with wide-open views. It's genuinely easy. The catch is there's zero shade, so on a hot day it's a morning or evening walk.

Willow Creek Path, down along the creek

The valley trail, down along the creek, surfaced in crusher fines like Pronghorn. It stays low, roughly level with the lower Creekside lot. The Town calls it partially shaded; I didn't find much cover. It's the shortest route to the dam, which the Town flags as a good picnic spot.

Echoes of Ancestors, the walk into Castlewood

At 0.8 miles, lots of flat slickrock and open sky. This is the trail that ties into Castlewood Canyon State Park, by the new Wildcat Canyon Trail the park built along its western boundary, so you can string both parks into one hike. Per the Town, a Colorado State Parks pass is required to enter Castlewood no matter how you get there (CPW lists a $4 day pass for entry on foot). It's full sun most of the way, and you'll see the old ranch house and outbuildings from parts of it. It gains about 117 feet, but gradually across the whole trail, so it walks easier than the number looks, which is why I rank it easier than Turkey Track.

Turkey Track Loop, easy loop, but you climb to reach it

The loop itself is 0.6 miles, short and mostly flat, and easy once you're on it. The catch is getting there: the connector up from the Creekside lot climbs about 82 feet in a quarter mile, a steady enough pull that my watch rated just that stretch moderate and my heart rate ran into the 140s. It also runs along the road and the neighborhood, so you'll see houses. The western portion has very little tree cover, with a bit more shade on the other parts.

Gobbler's Pass, and the step-through-the-rocks spot

At 1.1 miles, this one feels similar to Turkey Track. You get some shade, but you're not entirely protected, and you'll see houses off the western edge. The highlight is a genuinely cool spot where the trail steps through the rocks. Same note as Turkey Track: the loop is pleasant, but you climb about 112 feet from the Creekside lot to reach it, so factor the approach in.

Lost Moccasin, the staircase

This 0.8-mile trail is home to what the Town calls the property's signature 39-step stone staircase. Coming west to east, you climb it, and it will get your attention. The trail gains about 170 feet.

Big Bear Hollow, the overlook

If you do one view, do this one. Big Bear Hollow carries one of the property's premier overlooks, with sweeping views to the north and east across the forest and canyon. One thing to know: it's an out-and-back, not a loop. The overlook is a dead-end spur, so you either return the way you came or continue out through the open Golden Eagle connector. The Town lists it at 1.7 miles one way, so plan on roughly double for the round trip, and it's a real climb.

Bootlegger's Loop, the long one

The biggest single trail, 2.6 miles, looping between the two trailheads with about 300 feet of cumulative climbing. It has some rock steps and a bit of cliff exposure on the west side, and a steep finish. If you want the most trail in one go, this is it.

The routes I would actually put together

If you want my honest picks, here is how I would spend a visit instead of just ticking off loops.

My favorite outing, and the harder one: from Creekside, take Gobbler's Pass up to the Golden Eagle connector, over to Big Bear Hollow and the overlook, then up the Lost Moccasin stairs and down the far side to Bootlegger's, and out along Bootlegger's back to the car at Creekside. It's essentially the Town's own 'most challenging' route, which they clock at about 5.5 miles.

If you want something easier but more eventful than Pronghorn, two options:

• Willow Creek Path up to Big Bear Hollow and the overlook. You start low along the creek and climb to the view. Take it out-and-back, or keep going for a fuller loop.
• The short connector road, about a third of a mile, from the bottom up to the Golden Eagle area, then your pick: the west side of Gobbler's, or over to Big Bear Hollow and the overlook.

What is still closed

Two loops are still under construction and closed: Golden Eagle Loop (1.8 miles) and Rustler's Ridge Loop (2.2 miles). Note one wrinkle: the short connector trail that runs past Golden Eagle, linking Gobbler's Pass to Big Bear Hollow, is open. The loop itself isn't, and you'll simply find you can't continue onto it. Both are part of the 5 additional miles still being built, and when I checked with the Town's parks and trails staff, the expectation was that they open around September.

The two trailheads and parking

Creekside Trailhead is the first lot you reach, and it holds only 19 cars. It's closest to Turkey Track Loop, Gobbler's Pass, Willow Creek Path, Big Bear Hollow, and the lower end of Bootlegger's.

Cattleman's Trailhead is farther east, up the road past Creekside, and holds 125 cars. It's closest to Pronghorn Path, Echoes of Ancestors, Lost Moccasin, and the upper end of Bootlegger's.

Creekside's 19 spaces are going to be nothing on a weekend morning or evening. And right now, new and busy as it is, even Cattleman's can fill up. If both lots are full, you can start from Castlewood Canyon State Park next door and cross in on the Wildcat Canyon–Echoes of Ancestors connection. Castlewood has far more parking, but you'll need a Colorado State Parks pass ($4 on foot) to enter, and it's a longer hike in.

Where it is and how to get there

6581 Lost Canyon Ranch Road, Castle Rock, CO 80104, on the southeast edge of town, right up against Castlewood Canyon State Park. It isn't somewhere you stumble across. You have to go looking for it, and the last stretch is a residential road.

Here are the Town's own directions from I-25:

1. Take the Plum Creek Parkway exit, Exit 181
2. Turn east at the ramp and follow Plum Creek Parkway for 3 miles
3. Turn right at the roundabout onto Ridge Road, continue 1/2 mile
4. Turn left on Mikelson Boulevard, continue 1/4 mile
5. Turn right on Lantern Circle, continue 1/2 mile
6. Turn right on Lost Canyon Ranch Road

The road is nicely paved once you're through the entry gate, but the last stretch up to Cattleman's is gravel. Drive slowly, the entrance road runs past homes, and park only in designated areas.

Hours

• Summer (May 1 – Aug. 31): 5:30 a.m. to 9 p.m.
• Spring/Fall (Mar. 1 – Apr. 30, Sept. 1 – Oct. 31): 6:30 a.m. to 8 p.m.

Franktown Cave, and why you can't visit it

There's a nationally significant piece of history on this property, and you can't go to it, by design. Franktown Cave is one of Colorado's most important archaeological sites, a rock alcove with evidence of more than 8,000 years of Indigenous occupation. Its artifacts are curated at the University of Denver's Museum of Anthropology, and it's been on the National Register of Historic Places since 2006.

The cave is closed and protected by a buffer, its location is deliberately not published, and no open trail leads to it. The Town flags frequent rattlesnake activity there too. If you want to learn about the cultural sites, the sanctioned way is a guided outing through the Town's parks and trails program.

Summer 2026 events that support the trails

A handful of summer 2026 events raise money for Castle Rock's parks and trails, including the work out here at Lost Canyon Ranch:

• Stargazing with the Denver Astronomical Society — telescopes on the lawn right here at Lost Canyon Ranch, Friday, Aug. 14, 8–10pm, hosted by the Castle Rock Parks and Trails Foundation just after the New Moon (free, with a $20 donation suggested; because there's no after-hours public access to the open space, entry is only with the event's authorized guide)
• Twilight on the Trails — held right here at Lost Canyon Ranch, Saturday, Sept. 12, 2026
• Tunes for Trails, a free summer concert series at the Philip S. Miller Park Amphitheater:
  • Perks for Parks — Thursday, June 18
  • That Eighties Band — Thursday, July 16
  • Santa Rios — Thursday, Aug. 20
  • Ninety 90s — Thursday, Sept. 17

Before it opened

I got out onto this land in 2025, when it was still closed to the public. What sticks with me from that summer is the rattlesnakes. I ran into them out here more than once, which is why I don't treat the Town's warning as boilerplate. I didn't see a single one on my 2026 hikes, but I wouldn't bet on that holding.

Back then, buying a ticket was one of the few ways in. Get Outdoors Castle Rock ran a 2025 fundraising series called Discover Lost Canyon Ranch Open Space, and it wasn't cheap: Sunrise Yoga was $85 a head, held 6 to 8:30 a.m. at a private overlook, plus guided hikes, a full-moon hike, and stargazing at $30. They still run mornings out here, like a Beginner Bird Watching walk in May 2026.

As of Monday, getting in is free. You drive up and walk in.

How Castle Rock got it

The total cost was $15,009,432, and it took a coalition:

• Great Outdoors Colorado awarded a historic $3 million Centennial Grant in September 2023, the largest GOCO grant in Town history
• Douglas County provided $5.5 million from its voter-approved open space sales tax
• The Conservation Fund negotiated the purchase on the Town's behalf, from the former owner's estate
• Douglas Land Conservancy holds a permanent conservation easement that limits future use

The Conservation Fund acquired the property in April 2024 and sold it, along with its groundwater rights, to the Town in May 2024. The Town and the land-planning firm Wenk and Associates finished the master plan in 2025, and crews started building trails that fall.

With Lost Canyon Ranch, more than 6,900 acres, about one-third of Castle Rock's total land, is now preserved as open space.

Open space is one of the defining features of Castle Rock's quality of life. Lost Canyon Ranch Open Space reflects our community's commitment to preserving extraordinary places through long-term investment and strong partnerships so they can be enjoyed for generations to come.

— Mayor Jason Gray

There's also a 35-acre parcel on the southeast edge, near Horse Thief Cave, that the Town approved pursuing in early 2026 for $1.1 million. As far as I've heard, that deal fell out of contract, and the Town still describes the open space as 681 acres. If you know otherwise, let me know.

How I put this together

I hiked Lost Canyon Ranch myself over two days and tracked every open trail on an iPhone, an Apple Watch, and Strava. Every photo in this guide is one I shot on the property myself. The distances here are the Town's official numbers. The elevation, shade, and trail-feel notes are my own first-hand measurements and observations. Fair warning: I took a wrong turn or two, and I stopped constantly for photos, so my raw mileage ran long and my phone died before sunset. For exact trail distances, trust the Town's map, not me.

Been to Lost Canyon Ranch? Spot something I got wrong, or have a photo to share? Email me, I update this guide as readers weigh in.
