The difficulty of the "Upper and Lower Access Road Loop" can vary significantly. The access roads themselves are known to be rough, often requiring a high-clearance 4x4 vehicle for the last two miles. If you choose to hike into Rattlesnake Canyon from the trailhead, the terrain becomes moderate to strenuous, involving rocky and steep sections, minor scrambling, sliding, and carefully scaling 4-5 foot cliff sections to reach the arches. It is not generally recommended for beginners seeking an easy stroll.
Motorized access to the Rattlesnake Arches trailhead is seasonal. The Upper Road is typically open from April 15 to August 14/15, while the Lower Road is open from August 15 to February 14/15. Motorized travel is prohibited entirely from February 15 to April 15. Many hikers opt to walk or bike the roughest sections of the access road, especially during closure periods or if they don't have a suitable vehicle.
As the trail is located within the McInnis Canyons National Conservation Area, managed by the Bureau of Land Management (BLM), there are generally no specific permits required for day hiking, nor are there entrance fees. However, it's always a good idea to check the official BLM website for any updated regulations or conditions before your visit.
Information regarding dog-friendliness for this specific trail is not explicitly stated in the provided resources. However, as a general rule for National Conservation Areas, dogs are often permitted but must be kept on a leash. It's best to check the BLM website or contact the local ranger station for the most current pet regulations in McInnis Canyons National Conservation Area.
The best time to visit depends on your preferred access method and tolerance for heat. Spring (April 15 - August 14/15 for Upper Road access) and Fall (August 15 - February 14/15 for Lower Road access) generally offer more moderate temperatures for hiking. Avoid the peak summer months due to extreme heat. Winter can be beautiful but may present challenges with snow or ice on the rough access roads and canyon trails.
The primary draw of this area is the stunning concentration of natural arches within Rattlesnake Canyon. It boasts the second-largest concentration of natural arches in the world. You'll encounter notable formations like the famous Rattlesnake Arch, Hole in the Bridge Arch, and Cedar Tree Arch. The landscape also features piñon-juniper covered mesas and diverse geological features carved into rose-colored Entrada sandstone cliffs.
Parking is available at the trailheads at the end of the Upper or Lower Black Ridge Roads. However, be aware that these roads are very rough, especially the last two miles, and often require a high-clearance 4x4 vehicle. Many hikers choose to park further back and walk or bike the more challenging sections of the access road to the trailhead.
Yes, the route for the Upper and Lower Access Road Loop utilizes sections of several official trails. You will find yourself on parts of the Serpentine (56%), Upper Access (55%), Lower Access (51%), Better Access (45%), and Main Access (44%) trails during your hike.
Given the challenging terrain and remote nature, you should bring plenty of water, sturdy hiking boots with good ankle support, sun protection (hat, sunscreen), and navigation tools (map, compass, or GPS). Layers of clothing are advisable due to temperature fluctuations. Snacks, a first-aid kit, and a headlamp (even for day hikes) are also recommended. Be prepared for scrambling and steep sections.

It provides outstanding opportunities for solitude and primitive recreation, allowing for a more intimate connection with the natural geological wonders.
Yes, there is an option to scramble up steep slickrock to connect the lower and upper trails within Rattlesnake Canyon.
