Sunday 9-4-2016: My wife, a friend, and I hiked to Koppen Mountain (Elevation 6031 feet). We arrived at De Roux Campground/Trailhead around 10 am. The last 6 miles of the forest road 9737 are not paved but are in pretty good condition except for some washboards and small potholes.

From De Roux Trailhead, we took Boulder De Roux trail #1392, De Roux Spur trail #1392.1, then Koppen Mountain trail #1225. The first 1.4 miles on Boulder De Roux Trail along De Roux Creek is very gradual. The sound of creek is pleasant. At the trail junction we took left to De Roux Spur trail. The next 1.2 mies on De Roux Spur Trail climb 900 feet. At the saddle we took left to Koppen Mountain Trail. There were some downed trees on Koppen Mountain Trail, but all were manageable one way or the other. The final half mile to the summit is very steep, 30% grade according to my GPS track. For reference Tiger Mountain Section Line is 30% grade. Mailbox Peak old trail is 40% grade.

Black huckleberries along the trails were ripe and yummy. These trails are shared with equestrians, mountain bikes, and motorcycles. So some parts of the trails are deeply rutted. And you must be careful not to step on horse droppings. Fortunately we did not encounter any horses, mountain bike, or motorbikes.

We reached the summit of Koppen Mountain in 2 and a half hours. The temperature was 54 degrees when we arrived. It went up to 60 degrees when the sun came out. We had all kinds of weather, cloudy, sunny, a passing light shower, and even thunders. We had a pretty good view at the summit, but the top of Mount Stuart was coved with clouds all day.
