Hiking
Embark on the Trillium Lake Winter Loop, an easy hike that guides you through quiet, snow-covered coniferous forests. The highlight of this 4.6-mile (7.3 km) route is undoubtedly the classic view of Mount Hood reflected in Trillium Lake. You will gain a modest 216 feet (66 metres) in elevation over approximately 1 hour and 57 minutes, making it accessible for most. The trail features wide, well-packed paths, including wooden boardwalks, and generally flat terrain around the lake.
When planning your visit, remember that a State of Oregon Sno-Park permit is required for parking at the trailhead from November 1 through April 30. This trail can become quite busy, especially on weekends, so arriving early is a good idea to secure a parking spot and enjoy the winter scenery before the crowds. Dogs are welcome to join you on the route, provided they remain on a leash.
This loop is a popular choice for various winter activities, including hiking, snowshoeing, and cross-country skiing. Its gentle nature makes it an excellent option if you are new to winter trails or simply seeking a scenic, less strenuous outing. The initial access from the Sno-Park can be steep, but the path around the lake is mostly level.
