Lmuma Creek is the smallest BLM-managed campground in the Yakima River Canyon, offering approximately 7 shaded riverside campsites with picnic tables, fire rings, and vault toilets ($15/night camping, $5 day-use).

The site features a small gravel boat launch for non-motorized watercraft (kayaks, rafts, paddleboards) and direct river access for wading and fishing, though campers must bring their own drinking water and note that no hookups are available.

Located at milepost 12 on Canyon Road (Highway 821), about 4 miles south of Umtanum, it's a quiet, first-come, first-served spot popular with paddlers and anglers, though occasional train noise and road noise from the nearby highway are present.
