This hike is a butt kicker! Approximately 8 miles in, 8 miles out... However, the last 4 miles going in is a near vertical trek. I believe it's 3000 elevation gain, which is crazy. I was about dead towards the end but we made a night of it so I was carrying lots of extra gear. Don't let this sway you from your plans as the hikers reward is found along the way and at completion. Fresh blueberries everywhere, several waterfalls, and the stunning lakes make it worth it.
