Yes it is right next to Triangle X Ranch. It is an easy road to the lower campground a little tricker to go further up but worth it is you can, The view from the tip was amazing to see the Grand Tetons. If it has rained the road it really rutty and big ruts to drive through, I was in a 29 foot motorhome and did great, but it has been three years ago.

It is the next right, heading north past triangle ranch, or across the street from the turn off for Cuningham Cabin.

Yes. East of TX and NPS boundary
