When does the gate on Nawghaw Poa Road come down? The Bureau of Land Management has posted the same answer for almost two years. The road and the parking area at its end are closed from November 12, 2024, to November 11, 2026, while crews build the new Sloan Canyon National Conservation Area Visitor Contact Station. That date falls on Wednesday, November 11, about three weeks from now.
The building itself is on a different schedule. Friends of Sloan Canyon, the volunteer group that works alongside the BLM, describes an October 25 trail workday as preparing the station grounds "for the grand opening in January." So the posted end of the closure and the station's public debut are two separate events, roughly two months apart. For anyone in Anthem planning a fall hike, the gap is the useful part. The petroglyphs never closed. Only the front door moved, and Anthem has other doors of its own.
Two dates that are easy to merge into one
The BLM's Sloan Canyon page still lists the November 11 end date and no opening date for the station. Laid out in order, the project looks like this:
- Fiscal year 2024. The BLM's 2024 Annual Manager's Report records the groundbreaking and says the station "is now under construction."
- November 6, 2024. The BLM announces the temporary closure. It covers Nawghaw Poa Road and the construction footprint for two years and reroutes access to two trails.
- January 23, 2025. The reroute maps are updated. The BLM page still lists them as current as of that date.
- November 11, 2026. The posted end of the road and parking closure.
- January. The station grand opening named in the Friends of Sloan Canyon workday listing. The listing gives no year or exact day, but it comes from the October 2026 calendar.
A third project adds to the confusion. The City of Henderson has its own Sloan Canyon Gateway park, and it is a different project from the BLM station. The city's concept includes a 1-mile natural trail loop, a half-mile glow trail with interpretive stops, a play area and community plaza, public art, solar-lit parking and a green restroom building. Its posted status is "Under Design." If a neighbor says the "Sloan Canyon park" is almost done, they most likely mean the federal building at the end of Nawghaw Poa Road.
What the detour actually changed
The BLM rerouted the Petroglyph Canyon Trail and the 101 Trail and moved parking to Democracy Drive. Friends of Sloan Canyon's access page gives the route from the 215. Take Eastern Avenue south into Anthem, turn onto Sun City Anthem Drive, then Bicentennial Parkway, then Anthem Highlands Drive, then Democracy Drive past Pinecrest Academy and Via Firenze.
Even before construction, that lot filled up. The same Friends page warns that the parking area often reaches capacity on weekends and that parking along Nawghaw Poa Road is not legal. Its suggestion for a full lot is to visit another part of the conservation area. The old visitor contact station at the trailhead was temporarily removed, and Friends of Sloan Canyon says it runs a mobile contact station on weekends instead. The BLM's directions come with their own caveat. Residential construction in the area changes the routes often, so the agency's advice is to search a map app for Nawghaw Poa Road.
That caveat says a lot about this corner of Henderson. The streets around the conservation area are still being built while the conservation area gets its first permanent front door.
The doors on Anthem's own side
According to Friends of Sloan Canyon, most of Sloan's hiking, biking and equestrian trails start from established trailheads in the Anthem and Horizon Ridge parts of Henderson. Two of them sit inside Anthem and were never part of the construction closure.
| Trailhead | How to get there | What to know |
|---|---|---|
| Anthem Hills Trailhead | Anthem Parkway south, left on Reunion Drive, left on McCullough Hills Parkway, then left into Anthem Hills Park past Del Webb Middle School. Follow the road around the power company building. | Henderson lists the site as Anthem Hills Park & Anthem East Trailhead, 2256 N. Reunion Drive. |
| Shadow Canyon Trailhead | Anthem Parkway south, left on Atchley Drive, which becomes Somersworth Drive, then left on Shadow Canyon Drive. The lot entrance is the first left after Lewiston Place. | Reached through the Anthem street grid with no highway driving. |
| Petroglyph Canyon, rerouted | Parking on Democracy Drive near the gate. | The posted closure of Nawghaw Poa Road runs through November 11. |
You can confirm the Anthem Hills Park address in the City of Henderson's facility directory. Hidden Valley, the southern entrance to the North McCullough Wilderness, is a much bigger trip. You go south on Las Vegas Boulevard, turn onto Southern Nevada Liteweight Road, and follow about five miles of Hidden Valley Road, part of it graded dirt. Friends of Sloan Canyon recommends a high-clearance vehicle for the most direct wilderness access. For Anthem, the trailheads off Reunion Drive and Shadow Canyon Drive are the everyday options.
Whichever one you use, plan as if nothing is there. Friends of Sloan Canyon notes there is no gasoline, sanitation or drinkable water anywhere in the conservation area.
The rules that will carry over to the new building
A new building does not change why the canyon is managed tightly. Congress designated the 48,438-acre conservation area in November 2002. The BLM calls the Sloan Canyon Petroglyph Site one of the most significant cultural resources in southern Nevada, with more than 300 rock art panels and nearly 1,700 designs dating from the Archaic era to historic times. These rules are posted now and apply under the current detour:
- Hours. From October 1 to May 19, day use runs daily from 8 a.m. to 4:30 p.m.
- Crowd limit. No more than 20 people may be in Petroglyph Canyon at once. Groups may need a Special Recreation Permit and are encouraged to join a BLM ranger-guided hike.
- Pets. Pets are not allowed in the Petroglyph Management Area, which includes the Petroglyph and Cowboy trails. Everywhere else they must be leashed.
- Parking. The BLM describes station parking as limited and may close the lot on busy weekends and holidays.
What the finished station will offer is less settled. The project's environmental-assessment FAQ described a 3,000-square-foot building, a half-mile interpretive loop, a 120-person amphitheater and parking for more than 80 vehicles. It also said visits to the Petroglyph Management Area would be reservation-based, with no fee station. Those were planning-stage proposals. Until the BLM publishes opening-day details, treat the reservation system and parking count as plans.
The 20-person limit and the weekend lot closures point the same way. On a busy Saturday in January, the new front door may be the hardest way into the canyon. The Anthem Hills and Shadow Canyon lots will still be on the Anthem side of the canyon.
Getting onto the grounds before the grand opening
There is one way to see the new station area before January without waiting for a ribbon cutting. Friends of Sloan Canyon's fall calendar includes three trail days and an outreach table, all with the BLM on the land:
- Saturday, October 24. A public outreach table hosted by Friends of Sloan Canyon.
- October 25, 9 a.m. to noon. Trail restoration at the Visitor Contact Station. Volunteers rake trail, move rocks and do vertical mulching on the station grounds. The listing calls it a good project for people new to trail work.
- October 31, 9 a.m. to noon. Petroglyph Canyon Trail restoration. The crew will repair switchbacks damaged by heavy rain in early August.
- Saturday, November 14, 8 a.m. to noon. Cowboy Trail restoration. It is capped at 15 volunteers and involves at least four miles of hiking.
The Halloween crew is repairing the same switchbacks a January visitor will climb on the way to the petroglyph panels. RSVP through each event page, since the Cowboy Trail day has a firm limit of 15 volunteers.
Sloan Canyon sits close to Anthem, and that proximity is part of what makes the neighborhood. When we talk with buyers and sellers in Anthem Country Club, nearby trailheads come up alongside the golf course and the Strip views.
