Headwaters Lodge at Flagg Ranch

We booked this site as it was the only place available for our dates. Everything you need in a campsite with full hookups and drive through site and good amount of room between neighbors. However the price is just too high. It is all about location and this campground is right between Yellowstone and Grand Teton. The one kicker (good or bad) there was absolutely no Verizon cell service. Showed on screen as No Service.

We stayed 2 nights here because everything else in the Tetons was booked solid...thanks to covid I think everyone (including us) is taking road trips to try to get away from people and be outdoors. The downside is that it makes the more touristy areas very full. We didn’t enjoy the price (way too spendy, imho), the campground was resoundingly meh, but it gave us a place to stay to enjoy the absolute beauty of the Tetons.

The meh:
The campground area is pretty much dirt so there’s a lot of dust when yahoos don’t drive slowly through the area. The spaces are close together, we strung a rope and hung up a tarp and some beach towels for some privacy. Our space was right next to the restrooms so people tended to just walk through our site without much care of privacy or personal space. And, you’re at the very north part of the Tetons park so you have to drive south about 15 minutes if you want to go to Colter Bay Area or other main trailhead spots. Oh, and the mosquitoes are huge, operate at all hours (got bit more in the mornings, weirdly), and have a ferocious taste for blood.

The not so meh:
The staff was really nice and helpful. There is a nice river access area very close to the campground entrance. And, most importantly, it was a place to use as a base for some really gorgeous hikes.

All in all, it was ok but spendy, the saving grace is the ability to stay in the area.

And there is no service except for a blip here and there along the drive through the park. The campground has zero service.

Great location between Yellowstone and Grand Teton, but closer to Grand Teton activities. No cell signal with TMobile, but lodge has free WiFi. We stayed in a cabin because the rv sites were full. Cabin was expensive and beds were uncomfortable, but the room was clean and the views from our cabin were amazing. Would probably not stay in a cabin again, but would come back for an RV site. Food at the lodge was very good and the store was reasonably stocked. Gas station on site.

Gorgeous area with full hook ups between Grand Teton and Yellowstone. Very close sites with a ridiculous number of tent and RV sites overall. The campground was abuzz with activity into the night. But we did not feel cramped due to the abundance trees and well laid out format of the campground. Short walk to snake river. Will absolutely come back here. Loved it! Highly recommend.

Great spot with full hookups. Definitely crowded, but not as bad as the other Flagg ranch location. No cell and very limited WiFi at the lodge. Closest cell service is 20 min drive toward Jackson. Boondocking sites nearby at the same turn off the highway are wonderful along the Snake River, but fill up quick. Wildlife everywhere and hot spring within walking distance. 2 miles south of Yellowstone south entrance and about an hour from Jackson Hole. Overall good experience.

This site is conveniently located between Grand Teton and Yellowstone National Parks and was a great center-point to set up and explore both parks. It is just minutes from the south gate of Yellowstone. There is a gas station and store, clean water, dish washing stations, good showers with warm water and pull-through sites. However, it is very expensive and a little crowded. If you don't need all the amenities there are free options nearby that are a lot of fun.

We stayed here to access GTNP and Jackson Hole. It was quite a drive to access the main attractions in those places. Would have been better access to the south entrance of YSNP. It was packed and the sites are very close together. A little difficult to make the tight turns with a large 5th wheel. The hook ups were awesome and people were nice. The facilities were not well maintained. A quick hike takes you directly to the river for epic views!!

We stayed here with a group and the campground did a nice job of keeping us together. The roads need work. Any rainfall will create puddles that make walking down the roads sort of like playing Tetris.

The sites are about 20' apart. Most sites are pull through and accommodate large trailers. There was plenty of shade.

The bathroom and showers are nice and well maintained. The water supply was turned off twice during our stay. The water pressure was low the entire time. Electricity was fine. The sewer dump pipe at each site was quite tall. Taller than the output pipe on my trailer. The dump pipe had two openings, one on top and one on the side close to the ground. My connection didn't work on the side opening due to how close it was to the ground so I was forced to use the top opening.

The Wi-Fi at the lodge was poor. I could get text messages through but that was it. There is ZERO cell service. The Phillips 66 at the nearby lodge had a better price on diesel than I paid in Rock Springs.

The campground is just too large for me and the price is high.

The campground needs to provide lessons on how to start and maintain a fire. The smoke was so bad that visibility was severely limited. Maybe it's the type of firewood that is sold.

If you're exploring Grand Teton National Park, consider a campground that is more centrally located within the park. Once we got to the southern areas of GTNP, the drive became tedious. Traffic wasn't too bad. The paved roads within the park are excellent!

Nice, wooded sites that are level. Roads are full of potholes, but we were able to maneuver the camper without issues. Laundry and facilities are clean and well maintained. Staff friendly and helpful. There is a gas station, restaurant and gift shop in walking distance. We stayed for 5 nights to experience both Yellowstone and Grand Tetons. Drive from camp to Old Faithful lodge is about 1 hr, then count on at least 40 min to travel in between main locations in the park. Drive from camp to Colter Bay in Tetons is about 40 min. If you don’t mind the drive, this is a good place to set up base. Price is high, but to us was worth the securing of a reservation compared to first come first serve in the parks. Take a bug zapper- mosquitoes can be bad. There is NO cell service in the area. Yellowstone has decent service on the east side and spotting on the west. Grand Tetons has better coverage than Yellowstone.
