We hiked this as an out-and-back trek on a snowy December day on our way out of the Black Hills - and it was beautiful. It starts out from the south side of pretty Horsethief Lake near Mount Rushmore. This hike heads through a steep draw guarded by granite sentinels on either side with plenty of old pine forest.
Be sure to take time to pause and look around at the top of each hill as you are treated to breathtaking views of the surrounding hills. This connects with Centennial #89 which can eventually hook up with either Grizzly #7 to Harney or the Blackberry Trail to Mount Rushmore.
