Robbers Roost trail. Many of the directions posted on various blogs and travel sites are lacking details to say the least. My daughter and I put the pieces together and found this really cool cave. Turns out it was pretty close to where we were camping outside of Sedona off of 89a going towards Cottonwood. This is how we got there, with photos of landmarks/ signs to look for. Leave Sedona and head west on 89a towards Page Springs.
A few miles outside of town look for a sign on the right of 89a that indicates FR 525, FR is Forest Road. You will turn to the right, on the other side of 89a are more forest roads that go all over the place.
FR 525 is immediately paved, but it will turn to gravel right away. This road is fine for most cars, but it is bumpy. Camping is allowed all along this road. You will see the dispersed campsites as pull offs on both sides of the road. Basically all these forest roads allow camping unless there a specific signs that state “no camping”. Some are only big enough for one tent, others will accommodate a half dozen rv’s. Anyway, go approximately 4 miles on FR 525, then turn at the next fork onto FR525C. This road is slightly less smooth. Slow travel for most cars but you’ll be okay if you take your time. You will see a sign that says “Trail”
this is NOT the trail you seek! I have no idea where it goes or what trail it is but it is not the Robbers Roost Trail. that hikers use. It may be a bike path trail that circles around though. After about 6.5 miles you will see a sign that says “End of Yavapai Maintenance”, (pic below)
turn right here. After another 4 miles, you will see FR 9530,
turn right onto FR 9530 and you will soon see the first parking lot. Unless you have an ATV, or a high clearance 4X4, park here. It is about a 1 mile hike to the second lot and trailhead. The cave is on the back side of the red rock/hill to the right as you walk into the second parking lot. Take the well beaten path down the hill. It only takes a few minutes to get to the cave. Have fun!
