Did the Castle Trail / medicine root loop. Nice views and flat, but hot. Paranoid about rattlers but didn't see any. Hot. No water at trailhead; pit toilet. Crowded at parking lot but trail is empty.

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.

Great scenic trail, a must-do if visiting Mount Rushmore since it offers hidden angles to see the faces from!

Took the three kids on their first difficult hiking trail. Used our Piggy Backpack to carry the three year old when he got tired out. This is a must do trail :). Got a few geology lessons from my husband along the way.

Beautiful. Rocks are slippery when wet. Can be tough for dogs.

I agree with everything everyone said that reviewed this trail. We did it in the middle of the day and there was no shade. The map we got from the Rangers said the complete loop was 4 miles (not 1.5 listed on the info page)

This is a very cool hike. If you are afraid of heights, this is not for you. Wear good hiking shoes as there is loose dirt all the way up the trail. I saw a lot of folks scooting down the trail on their butts. Once you make it to the top, you can continue on the Medicine Root Loop Trail which is another 4 miles. Take lots of water!
