Hiking in British Columbia's Cathedral Provincial Park is over 33,000-hectare (80,000-acre) mountain wilderness of azure lakes, alpine meadows, and jagged peaks lying on the transition zone between the North Cascade and Okanagan Mountain Ranges. The entrance to the Park is about 30 km from the town of Keremeos in Southwestern British Columbia. The lower levels of the Park are predominately Douglas Fir stands, changing to Lodgepole Pine, then Engleman Spruce and Sub-alpine Fir as you reach the elevation of the core area.Lyall's Larch, heather and lupines are common in the higher alpine areas.

Mountain goats, California Bighorn sheep and mule deer frequent the high alpine ridges and meadows. High amongst the rocky outcroppings hikers are likely to see large hoary marmots or perhaps the shy pica.

  Many naturalists and birders visit the park each summer. Lists of over 36 different species of birds and well over 500 varieties of plant life have been compiled over the years. Four of the eleven endangered plants of the North Cascades are found in Cathedral Park.

The Cathedral Rim Trail is the main attraction in Cathedral Park. This ridge hike (2500 meters above sea level) with spectacular views of the North Cascade and Coast Range mountains leads to the unusual geological formations unique to Cathedral Park.
