Copper Creek Trail is a 15.5 mile moderately trafficked out and back trail located near Lostine, Oregon that features a lake and is rated as difficult. The trail offers a number of activity options and is accessible from March until October.
Beautiful area with good elevation gain. Once off of the main trail onto Copper Creek Trail proper, I only met about 5 people (went in July on a weekend). There are two required stream crossings so make a decision to go through barefoot or run wet. Last mile or so is tougher mainly due to 7000+ foot elevation. Still had some snow, not much wildlife. The only confusing part was the mileage; I went 6.6 miles up but wasn't at the crossing so perhaps the CCT was described as 13.2 miles NOT counting the 3 mile first section. Mosquitos were rare as long as you keep moving. For barefoot runners, I did over 2 miles without problem.
