"With the recent completion of Rustler's Ridge Loop at Lost Canyon Ranch Open Space, all trails have now been completed and are open to the public! That's a total of approximately 15 miles of trail to explore!" The Town of Castle Rock's parks and trails team posted that on Sept. 28, 2026, as reported by DougCo Social. If your only visit was during the opening rush in July, you walked about two-thirds of what's there now. The full property has only been open for a couple of weeks, and its longest days of the year are already over.
The Property Grew Twice After Opening Day
The open space opened on Monday, July 13, with 681 acres and 10 miles of looped and connected trails. It also opened with two accessible trails, two trailhead parking areas and a connection to Castlewood Canyon State Park. The Town's opening announcement said another 5 miles of trail would be built over the following months and finished in the fall.
That work is done. The Town's third-quarter project update lists "all trails and first phase improvements complete." The same update reports that the Town closed on the neighboring 35-acre Guardian Angel property, which brings Lost Canyon to 716 acres and ends the private access that used to run through it. The last two loops to open were Golden Eagle Loop at 1.8 miles and Rustler's Ridge Loop at 2.2 miles. Together they make up 4 of the property's roughly 15 miles.
Some Town pages still list the earlier figures. The July release and parts of the Town's FAQ use 681 acres and describe trails still under construction. Go by the third-quarter report and the Sept. 28 announcement.
This piece of land counts for a lot in Castle Rock. Lost Canyon Ranch was the Town's largest one-time open space purchase when it closed in 2024. The deal was a partnership with Douglas County, Great Outdoors Colorado, Douglas Land Conservancy and The Conservation Fund. With it, more than 6,900 acres are preserved as open space, about one-third of Castle Rock's total land area.
October Is the Last Month With an 8 p.m. Close
The trails are finished just as the hours start to shrink. The property is open every day of the year, but on a seasonal schedule.
| Season | Dates | Hours |
|---|---|---|
| Summer | May 1 to Aug. 31 | 5:30 a.m. to 9 p.m. |
| Spring/Fall | March 1 to April 30, Sept. 1 to Oct. 31 | 6:30 a.m. to 8 p.m. |
| Winter | Nov. 1 to Feb. 28 | 7 a.m. to 5:30 p.m. |
Starting Nov. 1, the property opens half an hour later and closes two and a half hours earlier. That matters most for the routes that the new loops made possible, which are the longer ones. The Town doesn't allow entry before opening or staying past closing unless it gives permission. So for the rest of October, there's still time after work for a long outing. After Nov. 1, the same route has to fit inside a much shorter afternoon.
Where the Climbing Actually Happens
The Town's trail map shows color-coded loops linked by shorter connectors. It rates only Pronghorn and Willow Creek as easy and puts most other trails at moderate to difficult. DougCo Social hiked the property and found something the map doesn't show. Several trails don't start at either parking lot, and the connector you walk to reach them is often the steepest part of the day. The reporter's watch measured about 82 feet of gain in a quarter mile up to Turkey Track and about 112 feet in 0.4 mile up to Gobbler's Pass. The high ground around Golden Eagle and the Big Bear overlook sat roughly 170 feet above the lot.
Here are the trails, using the Town's distances as reported in that guide:
- Pronghorn Path, 0.6 mile. A flat crusher-fines loop right at Cattleman's Trailhead with wide views and no shade at all.
- Willow Creek Path. A short, level valley trail along the creek. It's the shortest way to the dam, which the Town points to as a good picnic spot. The Town's map says the canyon itself was carved by Willow Creek.
- Echoes of Ancestors, 0.8 mile. Flat slickrock and open sky, with views of the old ranch house and outbuildings along parts of it. The Town keeps the ranch house, which dates to 1976, and the 1969 feed barn closed to the public.
- Turkey Track Loop, 0.6 mile, and Gobbler's Pass, 1.1 miles. Both are partly shaded. Gobbler's has a spot where the trail steps through the rocks.
- Lost Moccasin, 0.8 mile. This is where you'll find the 39-step stone staircase the Town calls the property's signature feature.
- Big Bear Hollow, 1.7 miles one way. An out-and-back to one of the property's best overlooks, with views north and east across the forest and canyon.
- Bootlegger's Loop, 2.6 miles. The longest single trail. It runs between the two trailheads with about 300 feet of climbing, some rock steps and a steep finish.
- Golden Eagle Loop, 1.8 miles, and Rustler's Ridge Loop, 2.2 miles. These are the newest trails. When DougCo Social last updated its guide, the Town hadn't published difficulty ratings for them, and the reporter hadn't yet hiked either one. Golden Eagle crosses the high, open, rocky ground on the property.
A Full-Property Day, Now That It Exists
DougCo Social's favorite route is essentially the Town's own "most challenging" route, which the Town measures at about 5.5 miles. Until the Golden Eagle connector opened, part of that route wasn't available.
- Start at Creekside Trailhead and climb Gobbler's Pass.
- Take the Golden Eagle connector over to Big Bear Hollow and walk out to the overlook.
- Climb the Lost Moccasin staircase and drop down the far side to Bootlegger's Loop.
- Follow Bootlegger's back to Creekside.
If you want something shorter that still has a view, the same guide suggests starting low on Willow Creek Path and climbing to the Big Bear Hollow overlook. Another option is the connector road, about a third of a mile, up to the Golden Eagle area, then the west side of Gobbler's. On fall hours, the long route still fits in an evening. On winter hours, plan it for the middle of the day.
Nineteen Spaces at Creekside
Where you park matters more than you might expect. Creekside Trailhead is the first lot past the gate and holds 19 cars. It's closest to Turkey Track, Gobbler's Pass, Willow Creek, Big Bear Hollow and the lower end of Bootlegger's. Cattleman's Trailhead, farther east along the road, holds 125 cars and serves Pronghorn, Echoes of Ancestors, Lost Moccasin and the upper end of Bootlegger's. When Creekside fills up, the Town sends visitors to Cattleman's and allows parking only in marked roadside areas and pull-offs. DougCo Social reported that even Cattleman's can fill while the property is new. That's the reporter's firsthand observation, not a count.
If both lots are full, you can come in from Castlewood Canyon State Park. Echoes of Ancestors connects to the park's Wildcat Canyon Trail along its western boundary. The Town says you need a valid Colorado State Parks pass or day pass to enter Castlewood, no matter which way you arrive. DougCo Social, citing Colorado Parks and Wildlife, lists the walk-in day pass at $4.
To drive in, take I-25 Exit 181 and go east on Plum Creek Parkway for about 3 miles. At the roundabout, turn right onto Ridge Road, then left onto Mikelson Boulevard, right onto Lantern Circle and right onto Lost Canyon Ranch Road. The entrance gate is at 6581 Lost Canyon Ranch Road. The Town asks visitors to drive slowly through the neighborhood and not to park on nearby streets.
What the Trailheads Don't Have
- Drinking water. Neither trailhead has any.
- Reliable cell service. Coverage is limited, and DougCo Social found the paper maps at the trailhead gone on one of its July visits, so pick your route before you arrive.
- Room for dogs or horses. Pets aren't allowed anywhere on the property. This is an outright ban, not a leash rule. Leashed dogs are welcome at Castlewood Canyon, but you have to drive there, because you can't walk a dog in from Lost Canyon.
- Bike access on trails. Bikes are allowed on the interior roads only, and both trailheads have racks.
Both trailheads have portable restrooms. Cattleman's has a hand-wash station, and Creekside has hand sanitizer. Visiting is free, and you don't need a reservation.
Not everyone has welcomed the rules. The Denver Gazette reported mixed reactions to the dog and bike limits and traffic concerns from neighbors. The early visitor comments that Douglas Land Conservancy shared in August praised the range of routes, the signs and maps, and the canyon views, rock formations and creek-side shade.
Two Town Dates Around the Hours Change
Two downtown events fall on either side of Nov. 1. The Town's Fall Festival is Sunday, Oct. 18, from 10 a.m. to 3 p.m. at Festival Park, 300 Second St. It has harvest vendors, pumpkin decorating, crafts and the Creepy Crawlies Around the Rock animal booth. If you hike in the morning on fall hours, you can still make the festival in the afternoon.
Starlighting comes on Saturday, Nov. 21, three weeks into winter hours. It runs from 2 to 6 p.m. at Historic Wilcox Square and Festival Park, with the ceremony at 5 p.m., the star lighting around 5:30 and fireworks afterward. The firefighters' 90th annual chili supper is part of the day. Lost Canyon closes at 5:30 p.m. that day, right around when the star is lit, so an early hike and the downtown ceremony fit together without overlapping.
Living near open space like Lost Canyon is part of what makes a Castle Rock address valuable. If you'd like to talk about what Castle Rock's trail and open space network means for your home, T.J. Gordon is happy to share local insight. Let's connect.
