Tallest-Youngest-Highest-Largest. These are just a few of the words that describe South Sister and some of it's features. It is the tallest of the Three Sisters, outdistancing both Middle Sister and North Sister. As well as being the third tallest mountain in the state of Oregon. It is the youngest, geologically speaking having the most recent volcanic activity of the Three Sisters. Highest describes the lake that sits right near the summit, Teardrop Pool, being the highest lake in Oregon. Lastly, largest describes Prouty Glacier, holding the distinction for the largest glacier in Oregon.

To the North, awesome views of the neighboring Sisters await you at the summit. To the Southeast, Broken Top, Mount Bachelor, and Green Lakes are visible. Even Mount Hood, Mount Adams, and Mount Thielsen may be visible on a clear day.

Excellent climb for first year climbers looking to prove their fitness.  Contact leader for more information.
