Description

Added by Spud Groshong

Distance: 7 miles roundtrip (out and back). Elevation gain: 5,166 ft. Duration: 4-5 hours. Highest point in South Dakota. Incredible stone lookout. Great views of the black hills.

The Harney Peak Trailhead #9 is located in the northwest corner of the parking lot just beyond Sylvan Lake. From there, the hike is very straight forward – the beginning of the trail is very moderate, being slightly flat with a few ups and downs along the way.

Once you cross into the Black Elk Wilderness (don't forget to fill out the permit before moving forward), the trail descends a little more to the valley floor. On the other side of the valley, the hike intensifies for the last mile or so, heading uphill. The last quarter of a mile is mostly stairs. Once you get to the top, however, you will forget all about the climb, as you are struck by the beautiful views.

At the top of Harney Peak, if you are so inclined, you can hike quite far up on the climbing rocks.

Be sure to bring layers and rain gear with you in the summer months. The weather will change almost at the drop of a hat.

Hiking to Harney Peak Reviews

Beautiful Oct weather

Super fun tho

This was a really cool hike, passing through the Cathedral Spires as you make your way to the tallest point in South Dakota. Once at the top you have great views towards Wind Caves and the rest of the Black Hills. In addition, there is a cool observation tower that sits atop Harney.

I've done this hike twice and both times in the month of August. The first time a storm was rolling in and we decided to push for the summit, made it but quickly departed as we heard thunder so we made a very quick escape. The second time, almost exactly a year later we had perfect weather and few crowds. I love this hike and the views of the spires!

We loved this trek. A bit crowded but for good reason. Take trail #9 up and trail #4 back down. Trail #4 is a bit longer and will take you through some incredible spires. Enjoy!

This was surprisingly easy and steady for being the tallest peak in SD/ east of the Rockies. The trail gained elevation very subtly and provided fantastic views almost the entire way. Once at the top, we were able to see for miles and miles. Lots of area to get away from hiking groups and sit down for a beer. We even had service up top and facetimed my mom to show her the view! Loved it! It was the top of my list and it did not disappoint!
