Getting There: FR-525 / Loy Butte Road and the High-Clearance Requirement
The access road to Robber's Roost Trail is FR-525, also called Loy Butte Road — a Coconino National Forest dirt road in the West Sedona canyon country northwest of the main tourist corridor. From AZ-89A in West Sedona, take Dry Creek Road north approximately 3 miles, then turn left onto Boynton Pass Road. FR-525 branches off Boynton Pass Road to the northwest and is marked with a Forest Road sign.
FR-525 is a maintained dirt road but it is not suitable for standard passenger cars. High-clearance is the baseline — a truck, SUV, or 4WD crossover with at least 8 inches of ground clearance. The road has rocky sections, minor water crossings when wet, and several rougher stretches where a low-profile sedan would scrape bottom or get stuck. After any rain event, the road's softer sections can develop ruts. Do not drive FR-525 in a rental car without confirming your rental agreement covers unpaved roads.
The trailhead is approximately 3 to 4 miles from Boynton Pass Road along FR-525 and is marked with a small sign. The parking area holds approximately 8 to 10 vehicles. A Red Rock Pass is required — pay at the fee post at the lot. There are no facilities at the trailhead. The road to Robber's Roost is also the access road to Loy Canyon Trail, a longer and more remote hike in the same drainage; Robber's Roost branches off before Loy Canyon's main trailhead.
The Cave: Geology, Legend, and What You'll Actually Find
Robber's Roost cave is a classic Sedona sandstone alcove — a large concave recess eroded into the base of a cliff face by differential weathering of the Schnebly Hill Formation and the overlying Coconino Sandstone. The cave is large enough to walk into and sheltered enough to provide shade and protection from weather, which explains its long history of use. The ceiling shows the characteristic smooth, rounded erosion pattern of alcoves formed by wind and water undercutting a more resistant rock layer.
The cattle-rustler legend holds that the cave was used as a hideout by outlaws operating in the Arizona Territory in the late 1800s — a plausible story given the cave's remote location in a drainage with only one main access road, the shade and shelter it provides, and the historical use of the Sedona red rock country by both ranchers and those who preyed on them. Like many such legends in the West, it cannot be confirmed from historical records, but it is consistent with the landscape's character and the era's lawlessness.
The cave has also shown signs of earlier habitation. The Sedona red rock country was used by ancestral Puebloan peoples and their predecessors, and alcove shelters of this type were used as habitation and storage sites across the Colorado Plateau. Do not disturb any marks, deposits, or structural remnants inside the cave — all archaeological features on National Forest land are protected. Exploring the cave is fine; taking anything from it is a federal violation.
Trail Breakdown: Cave Out-and-Back and Full Loop
Trailhead to the Cave
Short, mostly flat approach through pinyon-juniper scrub toward the cliff base. The cave alcove becomes visible in the cliff face within the first quarter mile. Trail is sandy and well-defined. Minimal elevation gain. Most hikers reach the cave in 20 to 30 minutes.
The Cave — Robber's Roost Alcove
Large sandstone alcove carved into Schnebly Hill / Coconino formation cliff. Walk-in scale — fully enclosed overhead. Shelter from sun and rain. Rock art and habitation marks may be present; do not disturb. Out-and-back turnaround point: return the same way for ~1.0 mile RT total.
Loop Extension — Canyon Terrain
Continue past the cave for the loop option. Trail moves through Loy Canyon drainage with red rock walls on both sides. Modest elevation change. Quieter than the cave approach — very few other hikers typically on this section. Loop reconnects to trailhead after approximately 3.5 miles total.
Loop Closes at Trailhead
Full loop returns to FR-525 trailhead parking. Total time for loop approximately 2 to 2.5 hours at moderate pace. Carry 1.5 to 2 liters of water for the loop — no water sources on trail. Loop is best hiked counterclockwise to reach the cave first while energy is highest.
West Sedona Vortex Country: Nearby Trails and Combining Your Day
Robber's Roost sits in the same West Sedona canyon corridor as Boynton Canyon Trail and Long Canyon Trail — two of the most scenic moderate hikes on the west side of Sedona. All three trails are in the Dry Creek / Boynton Pass Road area and share the same geological character: deep canyon walls in Schnebly Hill Formation sandstone, pinyon-juniper scrub terrain, and the relative quiet that comes from being a few miles farther from AZ-179 than the Uptown and Village of Oak Creek trails.
Because Robber's Roost is short — even the full loop is only 3.5 miles — it pairs well with a morning in Boynton Canyon (6 miles RT, moderate) or Long Canyon (approximately 6-7 miles RT, moderate) for a full West Sedona day. Start with Boynton or Long Canyon while energy is freshest, then drive to FR-525 for the Robber's Roost cave in the afternoon. The cave is partly shaded and pleasant in afternoon light when other west-facing trails get more direct sun exposure.
Winter access can be limited. FR-525 drains slowly after snow events and can remain muddy or icy for several days after precipitation. Check current trail conditions before driving out in November through March. The cave itself stays cool year-round due to its north-facing orientation and the thermal mass of the surrounding rock — pleasant in summer heat, cold in winter.

Guided Tours in West Sedona and Boynton Canyon
Viator lists guided hiking, jeep, and vortex tours in the West Sedona canyon corridor. A guide with knowledge of the Loy Canyon / Boynton Pass area can navigate FR-525 safely, provide historical context for the cattle-rustler legend, and explain the geological formation of the cave alcove and the broader Schnebly Hill sandstone sequence.
