Sunset Mountain Snowshoe - Boise National Forest

4/30/2017

The snowshoe hike to Sunset Mountain Lookout from Mores Creek Summit north of Idaho City, Idaho allows for solitude and beauty on the way to the deep snow of the summit. You will work to get there, but the spectacular view at the top is worth it.

Trip stats

Elevation gain: ~ 1,700 feet (trailhead at 6,143 feet, lookout at 7,869 feet).
Distance: ~ 8 - 10 miles round-trip.
Snow conditions vary during the length of the hike and year to year. The first 1-2 miles of the trail is usually packed; at the upper reaches, there is usually a skier's track to follow and snow is excellent near the top of the mountain.
Driving Directions: Drive Idaho State Highway 21 (Ponderosa Pine Scenic Route) to Mores Creek Summit parking area at Milepost 52, 13 miles north of Idaho City. Permit is not required. Parking lot on east side of ID 21.
Total driving time from Boise, Idaho to trailhead ~ 1 hour and 20 minutes.
Difficulty: Moderate to strenuous - hike described here follows Sunset Mountain Road (FR # 316) to summit. We get off the forest road at 3.25 miles, head up steep, open slope near the top and avoid the last two switchbacks on the road.

Hike Directions

Starting from parking area at Mores Creek Summit, snowshoe up steep embankment to the east to follow Forest Road #316; there is usually tracks present from other snowshoers and skiers. This road switchbacks up to the right to hit a ridge, then continues down a valley and then back up to a high point with a clearing where Sunset Lookout can be seen in the distance to the southeast, ~ 1.25 miles into hike.
The road/trail then descends and goes through level terrain for another 0.75 miles. Valleys and mountains can be seen to your left (east).
Road/trail starts climbing; it stays to the right through forest and avoids the steep ridge on the left. At ~ 3.10 miles, the road/trail emerges out of the forest into a flat, wide area with a steep rise to the south. The road travels back through the forest on right (west) side of steep rise.
To avoid the last two switchbacks at the top, we hike straight up the open slope at 3.25 miles which at the top intersects with the final portion of road to top of Sunset Mountain and Lookout.

We follow the forest road, then climb to ridge and go south, short-cutting the road and head straight up last approach (0.75 miles) to summit.

Eighteen years ago, on our first snowshoe hike to Sunset Mountain Lookout, we ran into a skier coming down from the mountain. He said, as he turned and pointed, "turn left at the tall fir tree when you get to the clearing at the top of this rise." It was a bright sunny day and one of our first snowshoe hikes in Idaho. Every time I do this hike, I remember those directions and that tree, although we know the route so well after having hiked it once or twice a year for 18 years.

Over the years, the snow-filled parking lot at Mores Creek Summit, which is plowed, has more and more vehicles and trailers of snowmobilers, skiers and snowshoers. This is where two trailheads are located. The snow machines mostly run on the trail to Pilot Peak, on the north side of ID 21, as well as some skiers, while most snowshoers go up to Sunset Lookout on the south side. Getting up over the berm of snow from the parking lot and onto Forest Road #316 is a bit steep, but once you find the tracks and groove of the road, it climbs at a moderate incline. It heads south and southeastward up and then down a wide creek valley, then up to a clearing at the top of a ridge where the road then heads to the left (northeast) briefly before heading through the forest in a southeastward direction. The first view of Sunset Mountain Lookout can be seen - the building a small speck on the highest rise to the south.

After this clearing, the trail descends briefly and is level for ~ 0.5 miles before it begins to climb again. Clearings show the immensity of the Boise National Forest to the northeast, with mountains, deep valleys and tall trees with snow-covered branches. The only sound on this hike is our snowshoes crunching through the snow; the forest is blissfully quiet.

The last half of the hike is a steady climb that gets steeper as the road approaches the lookout. We short-cut the road and switchback straight up the open, steep slope just below the final rise to the lookout. Once up this steep rise, we meet with the forest road and follow it more or less the last few hundred yards to the top.

This winter’s snowshoe hike to Sunset Lookout proved to be one of the most spectacular trips this season because of record snowfall in Idaho and a recent storm that provided 5 inches of new, fluffy powder over a firm base. On the last 1/2 mile to the summit, we followed a skier’s track that made small switchbacks up the steep, final face to the top, where an expansive 360-degree view of white and grey mountains surrounded us. The fir trees were white, too, with only a few inches of green showing beneath branches under thick snow cover. Grey clouds floated by us, now and then obstructing our view. It was a surreal scene that not many get to witness.

Fred and I make this trek every winter. We rarely see others, except the occasional backcountry skier. Once away from the parking lot, the noise from the snow machines that run to Pilot Peak on the other side of the summit quickly dies away. Once we saw a snowmobiler, by himself near the top of Sunset Mountain years ago. We dug him out of a snow hole.

After an initial climb for 1.5 miles, the hike levels out as it traverses across a broad, flat area through a Ponderosa pine and Douglas fir forest in a southeasterly direction. A break in the forest allows a first glimpse of Sunset Mountain Fire Lookout. At about 2 miles, you find yourself on a ridge overlooking a stunning valley with the Boise National Forest at your feet.
Unfortunately, much of this area was burned in the Pioneer Fire in August 2016. As the trail starts to climb again, you can choose to stay on the path the road takes leading to the right, or stay on the ridge with steeper hiking to the left (east of forest road). Further up, ridge and road meet at a small flat area where the top of Sunset Mountain finally comes back into view. This is where the real climbing begins. We hike straight up the final mountain face, instead of taking the gentler, longer road to the top.

Ascending the last steep pitch just below Sunset Fire Lookout

Once on top, the breeze is colder and the snow is deeper, for the elevation at the fire lookout, which is manned in the summer is 7,869 feet. The incredible view of multiple mountain ranges is worth the effort. The edge of the Sawtooth Mountains can be seen toward the northeast. We wish we could hang out at the top longer on those winter days. We decide to get some pie at Trudy’s Kitchen in Idaho City. We’ve definitely earned it. The thought of warm home made apple pie and the stinging in our hands motivates us to start descending the 1,700 feet down to the parking lot.
