A moderately steep climb through spruce-fir forest leads to a junction offering hikers the option to visit Siyeh Pass (7,750-ft.) or Piegan Pass (7,570-ft.). Both are great destinations and can be combined for a long, memorable day hike. The scenic Siyeh Pass trail ascends beautiful Preston Park on easy grades, passing through stands of subalpine larch, dwarf firs and stunted pines interspersed with pretty meadows dotted with wildflower. Along the way enjoy wonderful views of Mt. Siyeh (10,014-ft.) and Piegan Mountain (9,220-ft.).
At the head of the valley a steep trail ascends the northern slopes of Matahpi Peak (9,365-ft.) toward Siyeh Pass, a grassy saddle on the ridge running between Mt. Siyeh and Matahpi. The trail follows a route above and to the south of the pass and then switchbacks up Matahpi’s steep talus slopes to the Baring Creek/Boulder Divide. From the Divide, panoramic views extend south down the Baring Creek Valley to the west end of St. Mary Lake. Little Chief Mountain (9,541-ft.) and Mahtotopa Mountain (8,672-ft.) tower above the south side of the lake. A vantage point a short distance down the south side of the Divide offers fine views of the Sexton Glacier on the southeastern flanks of Matahpi Peak.
Most hikers turn around at the Divide, retracing their steps to the trailhead. If time and weather permit, return to the trail junction and hike to Piegan Pass. The pass enjoys terrific views of the jagged peaks along the Continental Divide and the Many Glaciers area. Another popular option is to continue over the Divide on a trail that drops steeply down the Baring Creek Valley to the Sunrift Gorge trailhead on the Going-to-the-Sun Road, losing 3,340-ft.
Check the current trail conditions before starting the hike. Snow may linger on the slopes of Matahpi Peak well into the summer, requiring the use of crampons to safely traverse the steep slopes leading to the Baring/Bounder Creek Divide.
Siyeh Pass: 9.4 miles round trip Siyeh & Piegan Pass: 13.4 miles round trip
The trailhead for Siyeh and Piegan Pass trails is located on the north side of the Siyeh Bend curve just east of where Siyeh Creek flows under the road. A brown sign, labeled Piegan Pass, marks the spot. You are actually starting on what is known as the Siyeh Bend Cut-off trail that climbs to meet the Piegan Pass trail.
From the road the Siyeh Bend Cut-off trail drops down to and travels along the right (east) side of Siyeh Creek. Straight ahead Cataract Mountain (8,180-ft.) and Mount Siyeh (10,014-ft.) rise above the head of the valley. To the left (west) Piegan Mountain (9,220-ft.) looms above the trail.
At 0.1 miles the trail turns right, curving to the southeast as it begins a moderately steep traverse through stunted pines and then thick spruce-fir forest, rock-hopping across a series of small creeks along the way. Two logs span a wide creek crossing at 1.0 mile. Rock hop across the next creek, located a short distance beyond.
Reach the junction with the Piegan Pass trail at 1.1 miles. The Piegan Pass trail to the right (south) drops downs to the Going-to-the-Sun Road. Bear left on the Piegan Pass trail toward Piegan Pass and the Siyeh Pass trail junction. The ascent continues as the trail curves to the north, crossing two more streams. Two logs facilitate the first crossing during high water. Otherwise both creeks are easily crossed on rocks without getting your feet wet.
At 1.4 miles the trail traverses a small meadow sprinkled with wildflowers. The open area provides your first views of the Going-to-the-Sun Mountain (9,642-ft.) rising above the trees to the right (east/southeast). Soon the thick forest gives way to intermittent meadows with partially obscured views of Piegan Mountain across the valley.
The lower slopes of Matahpi Peak (9,365-ft.), to the east, form the backdrop for a pretty creek spanned by a wooden bridge at 2.3 miles. Beyond the crossing the grade abates as the trail passes through stands of stunted trees and pretty meadows with fine views of Mt Siyeh (10,014-ft.) rising to the north, Piegan Mountain (9,220-ft.) to the west and Pollack Mountain (9,190-ft.) to the northwest.
Turn right (east) at 2.6 miles on the Siyeh Pass trail. The trail to the left (northwest) heads to Piegan Pass.
The Siyeh Pass trail ascends beautiful Preston Park on easy grades, passing through stands of subalpine larch, dwarf firs and stunted pines interspersed with lovely meadows dotted with wildflowers. The meadows afford great views of Mt. Siyeh rising above the north side of the valley and Matahpi Peak to the south. Behind you, to the west, Piegan Mountain fills the skyline. Soon views open to Siyeh Pass, the saddle on the ridge at the east end of the valley.
At 2.9 miles the trail passes to the north of a tarn and then makes a brief jog to the north before resuming its easterly course. Reach a wide, rushing stream at 3.3 miles. Wade or rock hop across the stream which drains a small lake cradled beneath the southern flanks of Mt. Siyeh.
Past the stream crossing the trail starts a steep climb up the northern slopes of Matahpi Peak toward Siyeh Pass, traversing meadows and talus slopes along the way. A few switchbacks facilitate the ascent. As you climb, enjoy ever improving views of Mt. Siyeh rising above the north side of the valley. To the west, Reynolds (9,125-ft.), Piegan and Pollack Mountains form a stunning backdrop for Preston Park’s gorgeous meadows and krummholz.
At 4.2 miles the trail travels above and to the south of Siyeh Pass (7,750-ft.), the grassy saddle on the ridge between Mt. Siyeh and Matahpi Peak. Continue following the trail as it ascends switchbacks up steep talus slopes toward the Baring/Boulder Creek Divide. As you climb, views open to the Boulder Creek Valley to the east of Siyeh Pass.
Reach the Divide (8,110-ft.), marked by a large rock cairn, at 4.6 miles. A knife-edge ridge rises above the divide to the east. The Boulder Creek Valley extends northeast below the Divide. Matahpi Peak soars overhead.
For the best views continue over the divide for a short distance. Soon views open to Sexton Glacier cradled in a bowl along the southeastern flanks of Matahpi Peak. Going-to-the-Sun rises to the south of Matahpi Peak. From this vantage point vistas extend south down the Baring Creek Valley to the west end of St. Mary Lake. Little Chief Mountain (9,541-ft.) and Mahtotopa Mountain (8,672-ft.) tower above the south side of the lake.
Most hikers turn around at the Divide, retracing their steps to the trailhead or, if time and weather permit, return to the trail junction and hike to Piegan Pass. Total round trip distance to hike to both Siyeh and Piegan Pass is 13.4 miles.
Another popular option is to continue over the Divide and descend steeply down the eastern side of the Baring Creek Valley, losing 3,440-ft. as the trail drops to and passes along the eastern rim of Sundrift Gorge. The trail ends at the Sunrift Gorge trailhead on the Going-to-the-Sun Road, 10.1 miles from the Piegan Pass/Siyeh Bend trailhead. At the Sunrift Gorge trailhead, catch a shuttle bus back to your car at Siyeh Bend. See the Siyeh Bend to Sunrift Gorge trail description for more information.
