The hike to Mirror Lake is 1.5 miles and has an elevation gain of 700 feet. Luckily it was a pretty easy hike because we got a late start that day and I had to be back at work in a few hours! There's also a beautiful trial that loops around the lake that we quickly walked around, only stopping for a few photos.
The hike back down was much quicker! I wasn't too worried about not staying a long time because we just bought a book that has a ton of secret free campsites all around Mount Hood National Forest! This means we'll be visiting Mount Hood many weekends in the coming Summer months.
