Agate Creek Trail Description (Trailhead 2K7) - Minimal Traffic

The Yellowstone is one of the last untamed rivers in the U.S. and this hike will give you a birds-eye view of this iconic river as it carves its way through the surrounding landscape.

From the Yellowstone River Picnic Area you'll climb a short hill among Douglas fir trees and large granite boulders (glacial erratics) that were deposited here over 13,000 years ago during a period of intense glaciation. After reaching the ridge in 0.2 miles you'll have spectacular views in all directions with the Yellowstone River winding through a narrow canyon on your right. The river lies about 500 feet below the trail and during the first two miles there will be a number of interesting viewpoints down into this steep canyon. At 0.4 miles you'll see the white slopes of Calcite Springs which emits a very strong rotten egg/ sulphur smell that, when conditions are right, can be a bit overwhelming. On a windy day this odor can drift as far as Specimen Ridge which is another three miles to the east. As you walk a little farther up the ridge you'll notice the river becomes restricted by a canyon know as the 'Narrows'. If you you look closely at the thin dark spires of rock that protrude from the canyon walls you may see birds nesting on the very tops of these towering spires. At just under two miles there is a wonderful view of the Yellowstone River and the rolling hills that border this stretch of the canyon.

At 1.9 miles the Yellowstone River Picnic Area Trail meets the Specimen Ridge Trail and begins a short but steep climb to the large plateau above. As you near the top of this short ridge be on the lookout for a single switchback that will take you to the right and up the remainder of this incline. After reaching the ridge the trail continues through a landscape of sagebrush that stretches as far as the eye can see. At 2.1 miles the Agate Creek Trail splits and begins heading south through similar terrain. Bison, pronghorn antelope, elk, wolves and grizzly bears can often be found roaming this giant plateau. As you continue south along the trail the summit of Mount Washburn will dominate the view across the wide canyon that cradles the Yellowstone River. To the east the barren hillsides leading to Specimen Ridge and Amethyst Mountain will be dotted with the dark silhouettes of bison as they quietly graze on the grasses found on these rolling hillsides.

At 4.6 miles the trail crosses Quartz Creek (often dry) and continues climbing gently toward its highest point at 7,642 feet. From here you can look directly across at Mount Washburn and the entire Washburn Range. To the right of this peak you may catch a glimpse of the Grand Loop Road and the occasional reflection of a car windshield as vehicles make their way up and over Dunraven Pass. This is a great place to stop for lunch and soak up one of the best views along the trail.

From here the trail descends 1,300 ft. to the banks of the Yellowstone in 1.6 miles. Trail conditions on this section are steep and gravelly and a little less than perfect, but are easily passable. The hillside is strewn with burnt and broken trees and new growth can be seen in areas closer to the river. At 7.2 miles you'll reach the only campsite along the trail, 2Y1 (★★). This is a nice site but it is still a half mile to the river which makes access to drinking water difficult. The campsite does have a great view of the Yellowstone River but hauling water to camp will be a chore.

The last half mile to the river is steep and rocky and ends in a wooded section along the banks of the Yellowstone. There is considerable blow-down that makes access to the large gravel bar to the north a test of balance, and you'll need to hop over a handful of downed trees to reach this isolated beach. The gravel bar extends about 0.2 miles north along the river and is a great place to fish. You can wade fish or cast easily from shore, either way the fishing is stellar here. The cutthroats are big, hungry and will take just about any pattern you dangle in front of them. Stay and fish until your arms get tired hauling in lunker trout and head back to civilization knowing you've seen another special place in the backcountry of Yellowstone.

NOTE: The trailhead for this hike is part of the picnic area. Please park near the outhouse or under the large pine trees in the center of the parking lot. This will leave room for those visitors who wish to use the picnic tables.
