There are a number of provincial parks and recreation areas within the boundaries of the Lillooet Ranges. The largest and most important is the Stein Valley Nlaka'pamux Heritage Park, which takes in the entire Stein River basin, immediately west of Lytton and east of Pemberton-Mount Currie. The Stein is the largest unlogged watershed in the southern Coast Mountains and, like the rest of the Lillooet Ranges, varies from coastal-type alpine in the west to desert-canyon arid on its east.
