"Excellent stop right of the interstate. Great national monument a part of the B.L.M. lands. It has a very well done interpretive center, and the grounds and parking area are meticulously maintained. There are stairs to the top of the rock as well as many trails. Plus, excellent views of the Yellowstone and its rock cliffs. Expect to spend 1-2 hours here."

"I had the place all to myself as I was there a couple days before it opened for the season. Such an awesome experience to be there all alone and really get a great feel for the area. I saw a juvenile bald eagle, and about 50 marmots running around. They were so stinking cute and a few let me get really close. It's about 200 steps to the top of the pillar and about a half mile walk from the entrance to the pillar area. I would definitely check it out if you're headed into Billings."
Tommy Dyson
"I totally didn’t expect the place to be so neat! While planning a trip from North Dakota to Yellowstone, I had AI check for any places to stop along the way and it suggested Pompey’s Pillar. I planned on stopping for a short time, stretching our legs, checking out the signatures on the rock and leaving. We didn’t have enough time to see the entire place but what we did was wonderful. Nice, clean bathrooms inside (if you’re there when it’s open) and we met a nice couple also from Arkansas that were working there. They gave us a bunch of information about our trip and the surrounding area, and helped our kiddo with his junior Ranger badge. If I come across this area again, we’ll plan for a longer visit."
