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.

I hiked this trail with my dad a long time ago; however, I am going back in a few weeks to do it again! I can't wait to get to the top of this trail! I remember the view being amazing!!!

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.

This was one of our favorite hikes. We took trail 4 up, trail 9 back. Do watch for thunderstorms, we were at the top and the clouds rolled in quite suddenly. We got halfway down the mountain and got caught in a thunderstorm complete with hail. At least the terrain on trail 9 was fairly easy and allowed us to pick up the pace! The rain was gone just as quickly as it came by the time we reached the bottom of the mountain and we were soaked to the skin. Our family (kids 18, 12, 9) agreed this certainly made the hike very memorable.

Beautiful views and a trail that didn't keep your gaze downward. We started too late in the day though. Didn't make the peak but was still a great hike!

Did this hike with my Wife and kids (then 7 and 9). Great sense of accomplishment for young hikers to climb a mountain. Only complaint was no gift shop at the fire tower on top. we took an alternate route to the top and came back on the main trail so we only saw other hikers on the return.
