Beautiful views, but I can’t stress enough to bring plenty of water and sunscreen as there is not a lot of shade and can be very hot. Definitely worth doing the entire thing and checking out Saddle Pass.

Great Badlands National Park scenery, prairie grass, flowers birds it was hot. Trail was mostly rock, gravel, dust with some small up and downs. We went to the MedicineCastle intersection and turned back for a 3 Mile hike.

I did the whole Castle trail, out and back, taking a detour for the north side of Medicine Root Loop. It was HOT. Make sure you take plenty of water. There are several spots where you climb up on the points which give great views. No Bugs/snakes/sheep, just lots of birds and flowers

HikingGreat!Rocky

So many great rock formations you'll feel like you're on Mars! Also saw a good spread of wildlife - deer, goats, prairie dogs! The trail is relatively flat - making it pretty accessible for most hikers! The only fret for some would be the heat and lack of shade! So I'd recommend going early in the morn if it's the summer months! Got plenty of beautiful photos! Parts of the Medicine Root loop are overgrown, but it didn't bother me none! This part of the trail was less exciting I'd say, but it showed off some of the local vegetation which was neat to see.

It was 95 and sunny so we just did the 6.5 miles lollipop loop and skipped the far leg of the castle trail. I would have rather done an out and back along castle- which was spectacular, instead of the loop which incorporates medicine root. It’s worth seeing the castle trail portion twice- really cool views of badlands. Bring lots of water, sunscreen and a hat. It was pretty brutal heat, so I recommend getting on the trail early.

This trail is pretty flat and scenic. We did it in August so it was very hot. Be sure to bring tons of water. We saw a lot of cool rocks and animals along the way. It was a cool experience but I don’t think you need to do the whole hike to get a feel for the area or hike itself. If you’re just there to checkout the badlands and not set on doing a long hike, I would recommend going out a mile or two and turning around. You will get the full experience in a few miles.

Super hot in the summer so bring lots of water. No shade, but that’s to be expected. Very pretty - saw 2 big horn sheep and 2 deer. Pretty easy, not much elevation change.

Broke Castle up over two days to hit both entry points as we have 4 small children. A great balance of prairie and rock with consistent trail posts. A must do.

We combined this one with Medicine Loop trail and wished we hadn't. We were eaten alive (though didn't see bugs, so didn't notice the bites until later) and found the hike somewhat boring. We did see some bighorn sheep, and heard rattlesnakes throughout, but we would recommend just going a couple miles down on this trail and coming back rather than doing the full 10 miles. We got bored and didn't find it worth the length. We LOVED the Notch Trail.

Beautiful hike. I accessed it via Saddle Pass Trail. Saddle Pass Trail is very short but also very steep trail. I recommend good hiking shoes and hiking poles. Coming down is very tricky. The rest of the hike was flat and no shade. Bring lots of water. I was lucky to see some sheep and no rattle snakes.

Flat and scenic trail with a few small scrambles. The first mile from the trail head was our favorite as it wound among the rock formations. We were lucky to see five male sheep on a bluff.

Disagree with the not being scenic comments you will find on here. Hiked 6/9 at about 1000 returned to car about 1500. Very cool views of both the badlands structures and wildlife. Saw ~18 bighorns and 1 rattler. Luckily it was about 55F and the rattlesnake was too cold to react because i stepped 6" from his head.Be very cognizant when walking through the trail surrounded by tall grass. Very muddy and alot of slipping. Very overcast and cool day on a sunny 90F day this would be brutal.

Not worth it at all. It's not technical and it is not really scenic. No viewpoints really standout. Quite frankly, it's just long and boring!

Fairly long trail; it feels even longer on a hot day. The trail is mostly flat besides having to trek through a couple of rock formations. No really steep portions though. The trail itself is really rugged and rustic. Parts of the path are not very visible, so the entire trail is marked with red metal stakes to keep you on course. I wouldn’t recommend it, if you’re not an avid hiker. There is absolutely no shade or respite from the sun, and that will wear on you, especially if you hike the entire trail. Be sure to bring plenty of water and apply sunscreen. If you are in good shape and an experienced hiker, I think you’ll really enjoy it. It totally immerses you into the very heart of the Badlands, and you’re able to see the rock formations and the beauty of the landscape up close. Be careful and watch where you’re stepping. There are rattlesnakes in this area. As my grandmother used to say, “Be safe. Have fun!”

Absolutely beautiful trail, you will feel fully submerged in the Badlands if you choose this hike. But be warned, it’s a difficult trail. There’s not much elevation gain, but there is no cloud cover and it gets very hot in the afternoon. So plan accordingly. We brought about 3 liters of water each. Be sure to follow the red markers the entire way. After this hike I truly felt like I had experienced the Badlands not just looked out at them. I would absolutely recommend it, while challenging it was really worth it. Note, if you hike all the way to the other side DO NOT cross I to the fossil exhibit if it’s under construction. A couple hiking ahead of us nearly received a $130 ticket!
