Stumbled upon this campground while fishing around at Grantsville Reservoir and decided to head up South Willow Canyon to review all these unreviewed campgrounds!  While the campground itself is officially closed for the season you could probably still camp here until the dirt road gets back enough that they close the gate towards the beginning of the canyon.  The main attraction for this and the Lower Narrows CG's is the extremely close proximity of amazing water carved bulletproof limestone climbing!  The Narrows climbing in South Willow Canyon is the premier HARD climbing spot for those in SLC that want to test their grit and push grades.  The routes here go up to 5.14a with very few routes under 5.11, although you can find moderates elsewhere in the canyon.  The 5.14a was but up by world renowned climber Chris Sharma and has been sent by other pros in the area like Jonathan Siegriest who claims it as "one of the top 5 5.14's in Utah."

Now enough about the absolutely amazing climbing and on to the actual campground!  This is one of 2 campgrounds that has very large group sites, so if you're coming here with a mob then this is one of the places to check out!  The group sites cost $50 and $90 and can hold 30 and 50 people respectively.  There are also 6 single sites @ $15 a night.  During the peak season May-Sept you can reserve the group sites on the recreation.gov website but at all other times they are first come first serve.  Like all the other campgrounds in the canyon you also need to bring your own water and trash bags.
