The closure was announced in a social media post shortly after 2 p.m. on Nov. 12, according to the canyon's official channels. No cause was given, and no timeline for reopening was provided.

The Scenic Loop is a 13-mile one-way drive through the heart of the conservation area, roughly 20 miles west of the Las Vegas Strip. It is the primary motorized route through the canyon's red sandstone formations and serves as the main access point for most of the area's trailheads, picnic spots and climbing routes. Visitors typically pay an entrance fee per vehicle, and the loop draws hundreds of thousands of drivers and cyclists each year.

The sudden closure comes as Southern Nevada's outdoor recreation season is entering its busiest stretch, when cooler temperatures draw crowds to the canyon for hiking, rock climbing and scenic drives. The area is managed by the Bureau of Land Management, which has not publicly detailed what prompted the shutdown.

For now, would-be visitors are left without clear guidance on whether other parts of the conservation area remain open, whether reservations will be honored or refunded, or how long the closure might last. The canyon's timed-entry reservation system, which governs access during peak periods, adds another layer of uncertainty for people who booked slots in advance.

This is a developing story. Anyone planning a visit should check the canyon's official channels for updates before traveling to the area.
