If you've walked to the edge of Ascaya's private trail loop any time in the last two years and kept going toward Sloan Canyon, you've probably run into orange fencing, a rerouted path, or a parking area that wasn't where your map said it would be. That's not a random construction project. It's the Bureau of Land Management rebuilding the Sloan Canyon National Conservation Area's Visitor Contact Station, and the closure has quietly reshaped how the entire trail system around the McCullough Range gets used while it's underway.
Most of what's written about these trails online reads like nothing has changed. Travel sites still describe the petroglyph hike as if you can park where the old contact station trailer used to sit. You can't, and haven't been able to for almost two years. The closure lifts November 11, 2026, which happens to land right at the start of the season when these trails are actually worth hiking.
The closure nobody's updated for
The BLM's public notice is specific: Nawghaw Poa Road and the parking area at its end have been temporarily closed since November 12, 2024, and stay closed through November 11, 2026, while the agency builds a permanent Visitor Contact Station to replace the trailer that served hikers for years. During the closure, the Petroglyph Canyon Trail and the 101 Trail have been rerouted, with parking relocated to Democracy Drive instead of the original Nawghaw Poa Road lot.
That's a two-year window, not a few weekends of orange cones. If you've assumed the trail into Petroglyph Canyon, home to more than 300 rock art panels and roughly 1,700 individual designs left by Puebloan, Patayan, and Southern Paiute peoples, is closed for good, it isn't. It's been rerouted and relocated, and it comes back to something closer to normal this fall.
Why this has mattered more if you're already up here
Ascaya's own trail network, more than two miles of private path linking the community's neighborhoods, its Clubhouse, and its scenic overlooks, sits right against this same reserve. The community's own materials describe the adjacent Sloan Canyon National Conservation Area as wilderness exploration available beyond the gates, which means whatever happens on the public side of that boundary is part of the same morning walk for anyone living here, whether or not you ever leave Ascaya's fence line.
For two years, that public side has had one of its main access points rerouted around construction. If you've felt like the trails on the McCullough Hills side of the range have carried more foot traffic than usual, or that Democracy Drive parking has felt unfamiliar compared to what older trail descriptions describe, that's the closure working itself out in real time, not a change in how popular hiking has gotten.
The rules on these trails were never identical to begin with, and the differences matter more once you're navigating a rerouted system:
| Petroglyph Canyon Trail (100) | McCullough Hills Trail (601) | |
|---|---|---|
| Access points | Democracy Drive (rerouted, through Nov 2026) | Mission Drive or Anthem Hills Park |
| Dogs | Not permitted, service animals only | Allowed on leash |
| Hours | 8 a.m. to 4:30 p.m., day use only | Open access |
| Capacity | Limited to 20 people in the canyon at once | No stated cap |
| Best months | October through May | September through May |
The petroglyph trail's hard closing time and visitor cap exist to protect the rock art and the North McCullough Wilderness Area that surrounds it. The McCullough Hills Trail, which connects Mission Drive on one end to Anthem Hills Park on the other across roughly 8 miles, has none of those restrictions, which is part of why it's absorbed more of the traffic that would otherwise have gone toward the petroglyphs.
What actually flips on November 11
Two things happen at once when the closure lifts. The Visitor Contact Station reopens in its permanent form, and the reroute of the 101 and Petroglyph Canyon trails presumably reverts closer to the original route, though the BLM's own reroute maps have been updated more than once during construction, most recently in January 2025, so it's worth checking the agency's current trail map before you go rather than relying on a route you remember from before the closure started.
The timing lines up with when these trails are actually pleasant to be on. Trail data consistently puts the best hiking window at October through May for the petroglyph trail and September through May for McCullough Hills, since summer heat in an exposed, shadeless canyon with no reliable water source turns a moderate hike into a genuinely rough one. A reopening in the second week of November isn't just a construction deadline. It's the point where the trail becomes worth using again after months of best-avoided heat, and where two years of rerouted access finally clears at the same moment the weather does.
The three months in between
Between now and November 11, the practical move is to lean on the trails that were never part of the closure rather than waiting on the reroute to finish. The McCullough Hills Trail, sometimes referenced by its trail number, 601, gives you an 8 mile route between Mission Drive and Anthem Hills Park with no dog restriction and no visitor cap, which makes it the more flexible option for a weekend walk right now. The Cowboy Trail, which loops back to reconnect with the Petroglyph Trail further up the wash, is also open and gives hikers who want a longer route a way to see more of the range without needing the Democracy Drive access point at all.
If petroglyphs specifically are the draw, that hike is still possible through the rerouted access, just with the caveat that trailhead descriptions written before late 2024 won't match what you'll find when you arrive. The 20-person cap and the no-pets rule haven't changed. What has changed is where you park and which segment of trail gets you there.
The trail that's already yours
None of this touches the private loop inside Ascaya itself. The community's own trail system, winding past the Clubhouse and out to the Family Park, doesn't depend on BLM construction timelines or Democracy Drive parking. It's there every morning regardless of what's happening at the public trailhead a short walk beyond the gate.
What the closure does change is the calculation for anyone who treats the public side of the range as an extension of that private loop, which, based on how the community itself describes its relationship to Sloan Canyon, is exactly how most residents seem to use it. For two years, that extension has come with a workaround. Starting in November, it mostly won't.
