Outlier Peak is located 23 kilometres (14 mi) southeast of Whistler in Garibaldi Provincial Park.

Outlier Peak is more notable for its steep rise above local terrain than for its absolute elevation as topographic relief is significant with the summit rising over 900 metres (2,952 ft) above the Cheakamus River in 1.75 kilometres (1.09 mi) and over 1,800 metres (5,905 ft) above Billygoat Creek in four kilometres (2.5 mi).

[6] Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (orographic lift), causing them to drop their moisture in the form of rain or snowfall.

As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall.

The months of July and August offer the most favorable weather for climbing Outlier Peak.
