Headwaters Campground At Flagg Ranch
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.

Natural features

For avid anglers, the Snake River offers plentiful cutthroat trout, brook trout, and whitefish. This area is known for its remarkable fly fishing and photography opportunities.

Recreation
The Headwaters area is a prime location for wildlife watching and photography. Walk along the banks of Polecat Creek through wildflower meadows and conifer forests to capture that perfect photo of a beaver, moose, elk, bison, bear, or birds. The Flagg Canyon trail is a good option for all ability levels. This 5.1-mile out and back hike winds through meadows and cliffs along the Snake River, and features a waterfall. There is plenty of wildlife to see in this area, including marmot, elk, and white-throated swift.
Nearby
One of the many reasons visitors return to Headwaters at Flagg Ranch year after year is its close proximity to Yellowstone’s south entrance, just a few miles north. But while it wouldn’t be difficult to spend all your time exploring our country’s very first national park (and the second-largest in the lower 48 states), there is much to see and do in the opposite direction as well. Take a self-guided tour of Grand Teton National Park via the 43-mile Scenic Loop Drive, offering an opportunity to photograph the park’s famous landscape and local wildlife. Spend a few hours at Colter Bay Village, located about 30 minutes south of Headwaters Campground, where you can rent a kayak or canoe, take a guided boat ride to the majestic base of the Teton Range, or just enjoy lunch and the stunning lake view from the marina. Continue on and stop in at the historic Jackson Lake Lodge for its famous huckleberry milkshakes and spectacular Teton views through 60-foot tall wall-to-wall windows. While you’re there, book a scenic raft trip or park bus tour.
