Ashton-Flagg Ranch Road: A Long and Bumpy Road to Grand Tetons

Last updated May 28, 2021 | Published on Jul 24, 2020

The Rialta bumped and jostled as my husband Daniel swerved to avoid another set of potholes on Ashton-Flagg Ranch Road. We had been driving for 5 miles on unimproved roads that kept getting worse…and we had over 30 miles to go. This experience would be fun in a truck or a Jeep – but not so much in a motorhome. Of course, I had no idea that the roads were like this when we started out.

I met Daniel’s eyes with a worried expression on my face. Should we turn around? Or do we stay the course and hope that the roads improves?

The New Plan to Avoid Crossing Teton Pass

Rewind the clock back to this morning when I was plotting our route for the day. After yesterday’s harrowing drive over Teton Pass, Daniel and I were in no hurry to repeat the experience.

Our campsite was located on the other side of the mountains from Grand Teton National Park, however, which was a problem. There was no way we were going to drive over the pass and back every day to visit the park.

It was time for a new plan and a new campsite.

Camping in a National Park

I’m sort of obsessed with National Parks, and camping inside of one is my absolute dream. Unlike Glacier and Yellowstone, all the campgrounds in the Grand Tetons are open for the season. There is a lot of competition for these campsites, however.

Some spots have to be reserved in advance (and they booked up months ago). The rest are first-come first-served. This means we have to arrive super early to get a spot, and we were too far away for that.

Daniel and I decided to drive closer to the park. This way, we’d be better positioned to jump on an open campsite tomorrow morning. But where? We considered booking a hotel room in Jackson but they were outrageously expensive. Even the “budget” hotels cost over $200 a night.

Flagg Ranch to the Rescue

After a fair amount of sleuthing, I found a primitive cabin at Flagg Ranch. The ranch is located just north of Grand Tetons National Park on land that is managed by the Park Service. It was a bit of a drive, but the cabin was in our price range and located not too far from several nice campgrounds.

Even better – we didn’t have to drive over Teton Pass to get there. I found another route on Ashton-Flagg Ranch Road that skirted around the west and north sides of the mountain range. Win-win!

Out of the Frying Pan and into the Fire

Daniel and I were both feeling pretty tired after yesterday’s long drive, so we weren’t in any particular hurry to get started. Plus, it was only a 2-3 hour drive to get to the cabin. Easy peasy. So we had a relaxing morning and hit the road in mid-afternoon.

The drive was easy at first. We drove north through some rolling farmlands and a few small towns. The Tetons rose majestically behind us to the southeast.

Before long, however, our map program directed us off the highway onto a gravel county road. It was fairly nice for a gravel road and we didn’t think much of it. Because, surely this was just a shortcut to a nicer road.

This did not turn out to be the case. A few miles later, we were directed onto another unimproved road – and this one wasn’t as nice. It wasn’t horrible but it wasn’t the kind of road we should’ve been driving on.

But it got worse. At one point, the road was so washed out that I was sure we’d have to turn around. We were on a narrow one-lane road by this point, however, and turning around would have been impossible. Daniel gently coaxed the Rialta through the washout while I held on for dear life. Then we both breathed a sigh of relief.


We shouldn’t be driving on this road

Crossing the Mountains on Ashton-Flagg Ranch Road

Shortly afterwards, we turned onto Ashton-Flagg Ranch Road. This road would eventually lead us with Flagg Ranch – which was over 30 miles away. We left the farmlands behind and it was all forests from here on out.

The road was in slightly better condition than the ones we had just traversed, but only barely. On the bright side, the road was wide enough for two lanes. Passing by oncoming traffic would be much easier. Plus we could turn around if we wanted to. We stubbornly decided to stick it out.

“I don’t think we could handle a road much worse than this,” said Daniel as he deftly avoided a pothole. Famous last words.

Welcome to Wyoming!

Daniel and I soon passed the state line into Wyoming…and that’s when things really got interesting. By this point there was no gravel on the road anymore – Ashton-Flagg Ranch Road had devolved into a dirt track that went from washout to washout. Daniel slowed to crawl as we inched our way along.

The road was in this state for over 15 miles.

Eventually, we came to the Grassy Lake Reservoir where we started to see more people. Various folks were camped out by the side of the road here in the middle of nowhere. We must be getting closer to civilization of some kind.

After a few more miles of bad road, we entered the John D. Rockefeller Jr. Scenic Byway. Here, the quality of the road improved dramatically. It was still a gravel road but a nice one. Daniel cranked up our speed to a whopping 25 miles per hour.

Road signs warned oncoming traffic that the road was no longer maintained. Only high clearance vehicles were recommended past this point. Too bad there wasn’t a similar warning on the other end of the road where we entered it.

Daniel and I passed a number of nice camp sites along the side of the road as we approached Flagg Ranch. They had picnic tables and outhouses and were really spread out for lots of privacy. I later learned that these were free. Too bad they were all full.


The road finally improved after this point. Whew!


There was a big forest fire here some time ago.

We arrived at Flagg Ranch around 8:00 pm, relieved that the order was finally over. It took us a total of four hours to travel 65 miles. The Rialta was coated in dust but otherwise seemed intact – although we won’t know for sure until we inspect her more thoroughly.

Our cabin was cute and small and very rustic. It had no electricity or plumbing or linens – only a double bunk bed with a desk. I liked the cabin but the location wasn’t very nice. There were lots of little wooden huts tightly packed together in a semi-circle that ringed the campground. People were jammed into the area like sardines. There was hardly any privacy at all.

Daniel and I brought in our bedding from the Rialta and crashed hard. We would be up early tomorrow morning – and this time we hoped to finally get the perfect campsite.

Where are we now?

Hi, I'm Unicorn!

I am an avid hiker, traveler, and adventurer who is on the mission to explore hiking trails around the world.  I’m also obsessed with National Parks, long-distance trails and other outdoorsy things.

I hope to share this knowledge with you and inspire you to explore new hiking trails too!

    Wow! So adventuresome! I love your writing.

    • Unicorn

      Thanks Rod! This blog post accidentally published before I was quite finished with it this morning. I’ve fixed it now if you want to see some photos to accompany the story ☺️

    Really enjoyed your post here! Hope the roads improve from this point on! And great pictures.

    When we lived on Prince of Wales Island in SE AK for a year we were 60 miles from the nearest paved road on very rough logging roads. It beat up my truck that year. I have a week off work in August and our family is going to drive down to Denali park where we plan to camp for a night and then start the over 100 mile Denali Highway (not in the park) that connects the Parks highway and the Richardson. One of the most beautiful highways in Alaska, but all but a few miles is unpaved. We plan to take it slow and camp somewhere in the middle, there are no campgrounds or really any towns on the whole stretch. It should be fun, but not something I would try in a motor-home. Our Truck may not be as comfy as the Ride, but it does have it’s advantages. Plus Lara bought a large canvas tent last year that is large enough to hold about 4 cots. I’ll probably still be in my smaller tent. I’ve enjoyed reading your adventures, keep them coming.

      the Ride should say “your ride”

    • Unicorn

      That sounds like an amazing adventure! I’d love to make it that way some day, although in a different vehicle.

    Ahhh, my kind of road trip, it just doesn’t get much better than that! Now that you are settling into this epic adventure isn’t it time to give the Rialta a name, make her part of the family as it were? May I suggest Shirley, as in “Slowly but Shirley”.

    • Unicorn

      Thanks Gary ☺️☺️ Daniel and I actually have been discussing a name for the Rialta for some time. We haven’t settled on one yet though. It’s like a trail name, it needs to be just right. We’ll figure it out one of these days ☺️
