Blown Away

Hiking the Windy Pass Trail. 

Windy Pass is a vast alpine meadow that straddles the Gallatin Crest between the Sentinel and Eaglehead Mountain. At an elevation of 9,250 feet, the open, windswept plateau feels like the top of the world. It’s covered in wildflowers for a few short months. Atop the Gallatin Divide, the Windy Pass Trail, also known as Portal Creek Trail, intersects the Gallatin Crest Trail, which heads north along the ridge to the Sentinel and Hyalite Peak and south through the Gallatin Petrified Forest. Past the divide, the East Windy Pass Trail continues east into the next drainage, descending to Big Creek in Paradise Valley.

En route up to Windy Pass, this trail crosses Portal Creek, meanders through a few meadows with vistas of the Madison Range, and climbs to the broad expanse by the Windy Pass Cabin, a Forest Service rental cabin.

Hiking Directions
The Windy Pass Trail begins by the kiosk for the Upper Portal Trailhead on the east side of the road. Pass the trail sign and enter the pine forest. Descend to Portal Creek and cross deadfall logs or wade across the creek. Slowly gain elevation and cross a tributary stream by a beautiful cascade. Cross a second tributary stream, which forms on Windy Pass, and pass through a few small meadows. Climb up a short, steep stretch to an overlook of the Madison Range. Steadily weave up the mountain through a mixed forest of Engelmann spruce, lodgepole pine, and subalpine fir. Pass a waterfall on the left. At 2.5 miles, emerge from the forest onto Windy Pass, a large open expanse dotted with pines. At a posted junction, detour left across the plateau toward the Forest Service cabin a quarter-mile ahead. Cross the stream and head up the slope to the cabin.

Return to the junction and now take the other fork to Windy Pass. Follow the tree-lined meadow uphill for a half mile, topping out at the 9,270-foot Gallatin Divide and a signed junction with the Gallatin Crest Trail #96. This is the turn-around. After exploring the divide and the endless vistas, return along the same route.
