I approached it from the Cathedral Spires trailhead, which was the right decision - cool rocks and less people. Sylvan Lake was a zoo and there were a LOT of people on the trail where we merged about 3/4 of the way to the peak. Great views but summer weekends will be crazy busy.

This is our 2nd time hiking to Harney Peak and our 10 year old daughters first time. What an adventure. We started at Sylvan Lake trail #9 and when we came back, we came down trail 3 and 4 to get back to Sylvan Lake. Started at 9:30 and arrived at Peak @ 11:30. We arrived back to Sylvan around 3pm. It's good to take a lunch and spend about an hour, then make your way back down. Be sure to get in good condition for this kind of hike. Take plenty of water and good nutrients to keep up your energy.

This trail was awesome. It starts out pretty moderate, being flat & less rocky. As you start to get closer to the peak the incline gets much more steep and the air gets a bit thinner which makes the last stretch before the peak quite strenuous. Overall, the trail was definitely worth it & the views were spectacular. Multiple places to stop along the way with scenic views. Great for pictures! The lookout/peak has a great view of the span of the black hills & beyond but is quite windy & cold, so make sure to bring a few extra layers. 10/10 would recommend.

Be sure to experience Little Devils Tower. The best views of surrounding area. The Needles, Cathedral Spires, and Harney Peak.

What a great hike!! Grew up in Custer and this was my first time ever hiking it (now 38) my son (7) and I had a great day! We must have gotten lucky, others up on top said that they had never been on top with NO WIND.. We could see for miles... Well just until the earth starts to curve.. lol someone please tell me what's with all the multicolored flags hanging the some of the trees on top?? Get their about 7/8 am to avoid others and eat lunch at the top of SD!!
Be safe, Give A Hoot DONT Pollute!!

We hiked this trail with all 5 of our kids aged 3-13 and enjoyed it. Most of the trail was wide and well marked. The last 1/2 mile to the top was steep and challenging but the end view was well worth it. Being able to see the tower from several points along the trail was a great encouragement to move the younger ones on the way up. I would recommend that you have previous hiking experience before atempting to tackle this trail.
