"The Broken Arrow Trail is located in Sedona, Arizona. To get to the trail go north on I-17 from Phoenix and take exit 298 (Highway 179 to Sedona). Follow Highway 179 north towards Sedona. Approximately 13 miles from leaving I-17 you will turn right on a small road called Morgan Drive. There is a wooden "Broken Arrow" sign at this turn and the trial begins 1/4 mile down this road past a small residential section."
Copper State Cruisers impromptu run
If you are coming from the Village of Oak Creek and you get to the Circle K turn around and go back ~a mile there is a very small sign that reads "Broken Arrow" on the left side of the road, right at the road you need to turn on (Morgan Rd.). Turn there, be courteous and drive like a normal person through the residential area and at the end of the pavement is whee the trail starts. I've never approached from the VOC side so I don't know if the sign faces both directions.
If you are going toward VOC from Sedona then look for the sign about a mile or so past the Circle K.
There is absolutely no friggin way that BA is a 5.5, even wet it may be a 4 at best. Myself and others have gone up the steps in the evening or night after the tours stop running. Not hard at all. The time was (10-12 years ago) that I would go through there in a CJ5 with a vette engine, T-18 4sp (6.35 first) 4.10's a 2.5 lift and 33's and not get out without a little scrape here or there. Since the baby boomers are retiring the scene has definitely changed. It is like a superhighway.
Back in the day, you might see 15 a day of Pink Jeep Tours out there, now they are running >60 tours there a day and there are two other competing companies. The only good thing is because the tours bring $$$$ in the residents haven't been able to shut the trail down (yet).
You should have no problems in a modified Barbie

Cruiser as I know of at least a few 80's that have gone through stock and the worst thing was the one that went through with running boards jacked one up a little.
