Full disclosure, I'm not 100% on the long/latt I have provided here. I am doing this after our visit and think this is the correct spot. 

Cool spot up a dirt road on the way towards the Spence Trial Lawyers' College. We were on a loop by ourselves with a bathroom nearby, kinda surprising since it was dispersed. Just a 100 yards or so from a beautiful river. We never saw another person. 

Leave no trace.
