In 2001 the park was expanded to 355 hectares to include all of Pavilion Lake due to the presence of microbialites, a type of stromatolite important to research into astrobiology and other fields, and in 2010, it was further expanded to 2,544 hectares.

Within the park and along Pavilion Lake at its farther end from the main part of the canyon is Chimney Rock,[2] the Secwepemc'tsn name for which, K'lpalekw, means "Coyote's Penis", and is an important spiritual site.

A waterfall into Crown Lake, at the park's campground, is famous among ice-climbers as "Icy BC" and the walls of Marble Canyon are a major draw for rock climbers.

The park's campground is located adjacent to British Columbia Highway 99 as it passes through the canyon.
