Great Hike... We did a good portion in just under 2 hours.
I think you would be hard pressed to find this hike without 4 wheel drive.
The road up is pretty bumpy and that's even if you are able to find the right path.
The hike is gorgeous and I think it is a pro that your cell phone often doesn't have service. Keep that in mind though. I would definitely not do this hike alone.
Please see Ashley B's review as she is right on the money!!
