Trail
Notes
From the trailhead bulletin board on the north end of the
campground, the trail first climbs gradually up the west
side of Thirteenmile Creek through thick stands of douglas
fir, then traverses a few rocky talus slopes, all within
sight and sound of the burbling stream. At 0.5 miles, the
trail starts a series of long switchbacks up the west side
of the canyon, topping out on a long flat bench with
spectacular views of the 600'-high, glaciated granite walls
just across the canyon to the east.
On this bench high above the stream, the trail follows the
rock ledge north for about 0.6 miles, through a mixed
forest of douglas fir, western larch and ponderosa pine. At
about 1.2 miles, the trail loops west into the first of the
sylvan glades found on tributary streams draining east into
the canyon, thick with currants, wild roses and shrub
maples and stands of old-growth trees that have never been
logged.
Past this first small tributary canyon, the trail
alternates between traverses of open, rocky bluffs and
retreats back into the green shady tributary canyons (all
normally dry by July). From the high bluff overlooks, one
has long vistas south down Thirteenmile Creek to the
Sanpoil River canyon and also east to the rounded ridges of
the stream's headwaters. Though the long views are
wonderful, the shady tributary canyons are equally
appreciated on hot days, along with their abundant
birdlife.
At 3.0 miles,
just as the trail climbs out of the last tributary canyon
and crosses an open bald knob (GPS Point 1), one has wide
views southeast over the upper Thirteenmile Creek basin.
This can make an OK hike destination — but for even better
views of the upper canyon, one can leave the trail and
contour cross-country to the south across the bald, grassy
hillsides. Staying on a level contour, one passes over
rounded bluffs above the canyon and finally comes to a
promontory at 3.4 miles, with good views and a few large,
shady ponderosas (GPS Point 2). Return as you came.
Road to Trailhead
From the junction of Highways
20 and 21, just south of Republic, WA, drive south on Hwy
21 for 12.3 miles, through the Sanpoil River Valley, to the
signed Thirteenmile Trailhead on the left (east), at the
boundary of the Colville Indian Reservation. The trail
starts just west of the double vault toilet at the head of
the campground, near a bulletin board. This trailhead is
easily accessible by any passenger car or camping vehicle.
Camping
Options
The nearest
campground is the small USFS camping area right at the
Thirteenmile Trailhead, just off Hwy 21. There are 3-4
sites here on a graveled loop road, some with shade and
others more exposed, suitable for both tents and camping
trailers. Two of the campsites have picnic tables and fire
rings and two are just pulloffs into the trees. There is a
double fiberglass vault toilet and a stock ramp, but no
drinking water nor garbage disposal. There were no camping
fees in 2015.
NOTE: The USFS Ten Mile Campground, just 3 miles north of
the trailhead on Hwy 21, has been closed due to storm
damage for the past few years, and appeared abandoned in
June 2015. Contact the USFS district office in Republic for
an update. This was once a nice campground on the Sanpoil
River, with 9 sites suitable for both tents and camping
trailers, each with a picnic table and fire ring, plus a
vault toilet, but no drinking water.
Further afield, there are three USFS campgrounds at Swan,
Ferry and Long Lakes, about 12 driving miles west of the
trailhead on paved Road 53 (aka Scatter Creek Road), off
Hwy 21. These are developed campgrounds with vault toilets,
drinking water and are suitable for any type of camping
setup. Camping fees were $6-$10 per night in 2015.
