About Headwaters Campground at Flagg Ranch

Availability will go live on Recreation.gov on a 6-month rolling basis for RV sites, Tent sites, and Camper Cabins.   Located in the John D. Rockefeller, Jr. Memorial Parkway, directly between Grand Teton and Yellowstone National Parks and just minutes from both, Headwaters Campground offers the perfect basecamp for exploration. Situated in a spectacular wooded setting with rolling hills and Teton mountain views, this campground is the perfect place to unwind and unplug, as there is limited cellular or internet service. Commune with nature and spot bear, moose, mule deer, and more as you stroll along nearby Polecat Creek. For avid anglers, the Snake River offers plentiful cutthroat trout, brook trout, and whitefish. While none of Headwater’s campsites are on the river, all are within walking distance.    The campground offers 34 tent sites, 97 full-hookup and pull-through RV sites, and 40 Camper Cabins, and is open from June to October. Visitors are encouraged to plan ahead and book early.

Summary

AI generated

Headwaters Campground at Flagg Ranch is a well-maintained facility conveniently located between Yellowstone and Grand Teton, making it an ideal base for exploring both parks. Visitors appreciated the clean amenities, friendly staff, and additional features like a gas station, store, and free showers. However, some campers noted high prices at the store and close proximity of sites, which could lead to noise and lack of privacy. Overall, many expressed a desire to return due to the campground's positive aspects.

This is our 2nd time at Headwaters and we will come again! It is perfectly located to enjoy Yellowstone & the Grand Tetons easily. The grounds are safe and well maintained, the staff is knowledgeable and friendly, the store had everything we needed, and the campsites are shaded and not too crowded so we never felt like we were on top of the people next door.

Suggestions for improvement would be:
*Fix the squeek on the campground truck - it's pretty loud when doing the rounds early and late.

*Have a RV dump station ON SITE for those of us whose trailers are not tall enough to have sufficient drop to empty our Grey&Black tanks at our campsites. (The inlet was a good 10" above ground level) We were told we could use the nearest dump at Colter Bay campground - who had no sympathy and charged us $10 to use it. Not a deal-breaker, but definitely an inconvenience.

Other than that, we loved our trip! THANK YOU

The location was perfect, the campsite was clean and well maintained, and the rangers patrolled often to ensure we were safe. I will absolutely stay here again.

The bathroom was really clean and I liked that there was running water and flush toilets. The campground was clean. The only con I have is that the mosquitos were terrible. I sprayed myself twice and had a citronella candle going and I was swarmed and later found I was bit up. A lot of people were inside their camper/tents, probably to escape the mosquitos. Other than the mosquitos, I had a really nice time here.

I sprayed myself twice and had a citronella candle going and I was swarmed and later found I was bit up. A lot of people were inside their camper/tents, probably to escape the mosquitos. Other than the mosquitos, I had a really nice time here.

This is our 2nd time at Headwaters and we will come again! It is perfectly located to enjoy Yellowstone & the Grand Tetons easily. The grounds are safe and well maintained, the staff is knowledgeable and friendly, the store had everything we needed, and the campsites are shaded and not too crowded so we never felt like we were on top of the people next door.

Suggestions for improvement would be:
*Fix the squeek on the campground truck - it's pretty loud when doing the rounds early and late.

*Have a RV dump station ON SITE for those of us whose trailers are not tall enough to have sufficient drop to empty our Grey&Black tanks at our campsites. (The inlet was a good 10" above ground level) We were told we could use the nearest dump at Colter Bay campground - who had no sympathy and charged us $10 to use it. Not a deal-breaker, but definitely an inconvenience.

Other than that, we loved our trip! THANK YOU

We had a great experience with Headwaters Campground. We spent alot of time in the Grand Tetons and the location was perfect for seeing wildflowers and wildlife. The mosquitos were terrible but that is part of camping I guess. The laundry facilities were nice, except it was very expensive ($9/load) and the change machine was out of order. The gas and convenience store prices were all extremely high throughout the national parks which is a shame.

We loved our camping trip at Headwaters campground while visiting both Yellowstone and Grand Teton Parks. We recommend eating at Sheffield restaurant, the food and the service was great . All the employees we encountered at the restaurant, convenience store , gift store and campground were very friendly and helpful . We booked a beautiful scenic float down the Snake River, through Jackson Lake Lodge, and our van driver and river guide were awesome. We also did the Jenny Lake boat ride and hiked to the Falls and up to Inspiration Point which was wonderful. This is the second time we have camped at Headwaters Campground at Flagg Ranch and we will definitely be back. We visited in early June and the mosquitos were numerous other than that we love it there !
