The Nature Conservancy of Canada has a few Conservation Areas near Kamloops, the closest one being the Lac du Bois Conservancy.   Hikers access these lands all year, respecting the natural environment with responsible recreation:

“Walking, hiking, bird watching, responsible bike-riding and other low impact activities are welcome in the Lac du Bois Conservation Area.   However, some recreational pursuits harm this delicate area and threaten the species that live here.   Off-road vehicle use, littering, fires and uncontrolled dogs all have a significant negative impact on the vegetation and wildlife that we are working to protect.   Please respect these grasslands.   Tread lightly when you visit.”
