Activity Notes
Middle Sister is a scenic wonder in the Three Sisters Wilderness, a perfect climb for recent BCEP grads. The approach from the west side is less common than the Hayden Glacier and Southeast Ridge routes, but the route up the Renfrew Glacier is straightforward.
We will plan on hiking in on Thursday and camping at Arrowhead Lake, with the summit date on Friday. After summiting on Friday, we will return to camp (with a welcome dip in the lake), then hike out on Saturday morning before returning to Portland.
Please note this climb will be contingent on getting trailhead permits to Obsidian Trailhead.
