Mount Siyeh is rather easily accessible from a variety of different routes. It can be ascended via a long scree scramble from the Preston Park area, or from Piegan Pass via Cataract Mountain. The summit can also be reached via a long hiking/mountaineering route dubbed the "Skyline Experience"; this route starts from the Many Glacier Hotel and involves ridge walk and includes the summits of Wynn Mountain and Cracker Peak before reaching the top of Siyeh.

Geology

Like other mountains in Glacier National Park, it is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was initially uplifted beginning 170 million years ago when the Lewis Overthrust fault pushed an enormous slab of precambrian rocks thick, wide and long over younger rock of the cretaceous period.

Based on the Köppen climate classification, it is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers. Winter temperatures can drop below −10 °F with wind chill factors below −30 °F.
The peak of Mount Siyeh has a tundra climate or an Alpine climate.
