Activity Notes

South Sister is a non-technical walk-up and one of the easiest ways to become a Mazama member. This will be a two-day climb at a more relaxed pace. Day 1 (Saturday): Hike in to basecamp at Moraine Lake. Enjoy our time at the lake. Day 2 (Sunday): Summit South Sister from Moraine Lake, back to camp, hike out.
