The drive up is full of narrow switchbacks that you just hope and pray nobody else happens to be coming around at the same time as you are. There are some quite steep grades as well. Whoever set the speed limit at 30 miles per hour must have been a daredevil before they found employment as a civil engineer. However the road is decent enough that most any vehicle can navigate it. I had zero issues in my truck with a camper in the bed. A class B could get in there as well, but there's no room for anything bigger and good luck getting level. There is absolutely no room for trailers at all. There are only about 5 walk in tent sites that I saw with fire rings. The only amenity is a vault toilet. Be aware that you are on a mountain peak so it gets pretty windy. Your $40 Wally World tent will probably beat you to death in the night. Make sure you have a sturdy setup. If you can deal with all that though, the view is unsurpassed. Its just a small hike up to the tower where you can see in every direction forever it seems. The forest in the area is just starting to recover from wildfires a couple of years ago, but the contrast between the burnt old and the growing new is beautiful.
Note: a previous review stated the tower was closed, but it was back open by my visit in Sept 2017.
