The Trillium Lake Road Trail is a seasonal 4 mile out-and-back hike from Mount Hood Highway down to Trillium Lake and the Trillium Lake Loop Trail. Starting in late autumn and lasting through the early Spring, the Trillium Lake Road is closed off due to snow; however, during those seasons, the road can be used for hiking, cross country skiing, and even snowmobiling.
The hike starts off by heading downhill for about 0.4 miles before leveling off a bit. The trail then shoots back uphill and then descends one more time before reaching the Trillium campground and Trillium Lake. Once you reach the 2 mile mark (one way) you'll be at the southeast corner of Trillium Lake - where you can hop on the Trillium Lake Loop Trail for another 2 miles before heading back to parking.
Traffic: This trail was tracked mid-week early in the day, but we still saw a decent amount of people. It's moderately trafficked in the late fall, but considering the 4 to 6 mile distance, most people are spread out throughout the trails, so you may not run into many people during the shoulder seasons.
Views/Lookout Points: Once you reach the end of this hike, you get to Trillium Lake with views of the lake and Mount Hood.
