Here is my thread about my trip in the Black Hills and the Eclipse, last August.

As I noted in the thread, I stayed at Spearfish City Campground and rented a car. I was able to see a lot, and cover a lot of ground fairly quickly Be aware that the Motorcycle Rally at Sturgis is August 3rd thru the 12th and that participants will begin to arrive one to two weeks earlier than that. About 400,000 people attend, so don't stay too late in July or you will be surrounded by bikers during your sightseeing drives.
Also, I am surprised that no one has mentioned the fire....... Basically the southern half of Custer State Park, along with a portion of Wind Cave National Park were involved in a fire Dec 11th to the 18th. 58,000 acres were burned, according to the fire maps I looked at, all of the area surrounding the Wildlife Loop was burned and the area from the Needles highway and to the east of it. Oddly they lost no buildings.
This article says 54,000 acres, I have seen several different numbers. Also there was a fire in September in Wind Cave Nat Park that burned about 8,000 acres.

It appears a lot of the fire was a burnout of underbrush however I did see pictures of large areas of trees burning also. Damage was not as bad as it could have been.
With children do not miss the Mammoth Site at Hot Springs and also the Journey Museum in Rapid City, along with Devils Tower. Links are in my thread linked to above.
Have a good trip.
