Middle and North Sister Trail is a 16.8 mile lightly trafficked out and back trail located near Blue River, OR that offers the chance to see wildlife and is rated as difficult. The trail is primarily used for hiking, rock climbing, birding, and backpacking and is accessible from May until October.
This is a nice challenging summer mountaineering trip that take you to both North and Middle Sister in an overnight starting from the Obsidian Trailhead on Mckenzie Pass Scenic Highway. This trip takes you through beautiful alpine meadows, through massive lava flows and then up two 10,000 ft. volcanoes. Middle sister is challenging but doable by the average climber while North Sister's summit pitch is extremely steep.
