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.

I took an alternate route starting at Willow Creek Horse Camp which added another 1,000 feet of elevation gain and a round trip of 10.8 miles. It starts out meandering through meadows of tall grass and wild flowers. Then follows below a cliff for a while. From then on cliffs spring up all around you and the views are absolutely amazing. This trail is shared with horses so watch your step. I cant wait to bring my kids here.

I combined the Lost Cabin trail with the Harney Peak South and North trails for a great loop. The Harney peak from Sylvan Lake was crowded but but the rest of the loop I only met 2 other hikers. It was a great mix of scenery and terrain. 4 stars instead of 5 due to the heavy use from the horse camp on the north end. Watch your step! The link is to my tracks.

Fun hike with a variety of trail options so that the return trip does not have to be exactly the same. Great vista at the end. Advertised as the highest peak between the Pyrenees and the Rockies. :) Lots of interesting rock "needles" formations along the way.

One of the best hikes I've ever done. It took us about 90 minutes at a pretty good pace. You should allot 2 hours each way. The trail starts out across a meadow, but then ends up quite steep with lots of boulder hopping. You should bring water, wear appropriate shoes (not thongs or flipflops!) and apply sunscreen generously. The views are absolutely outstanding. The former Fire Station is in good condition and is a great place for lunch. There are no restroom facilities at the Fire Station Lookout. Go early in the morning when it is more cool. Avoid going to late in the afternoon as sudden thunderstorms can blow through.
