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.

Caribou-Targhee National Forest begins about 8 miles away, and it is the closest of these.

Each unit is published as a centre point and an acreage rather than a boundary, so this section stands it in for a circle of the same area. Whether a campground is inside, and how far it is from one it is outside, are both approximate.

Natural features

Headwaters at Flagg Ranch is situated in a tranquil setting along the upper reaches of the Snake River, surrounded by meadows and conifer forests. The Yellowstone Plateau rises to the north, and Huckleberry Mountain to the east. Within walking distance is Polecat Creek, which runs through forests, wildflower meadows, and thermal 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. Headwaters is home to elk, moose, mule deer, wolves, black and grizzly bears, a wide variety of birds and more. Bears are often seen on trails and in the developed areas.

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.
