Beautiful setting, but very popular so you'll not have much solitude. The road coming of the main road is a bit rough and uneven. Low ground clearance vehicles can make it but go slow. I managed fine with my Honda Odyssey but you could see evidence on some of the rocks and boulders where some vehicles had  scraped bottom.  

Cattle roam freely as this is open range, so don't be surprised to find that you might be sharing your site with some livestock. Watch your step!
