If you are in the Black Hills area in South Dakota, you really need to make a stop to Custer State Park.
This is not to be missed. The scenery is stunning, the forest of lush and thick.
The cost is $12 I believe, but the pass is good for 7 days.
Our favorite part of Custer State Park was taking a drive through the park and never knowing what was going to be around the bend. One time we had a buffalo right at the side of the road! When we went it never seemed too busy, so you could stop and take pictures.
Iron Mountain Road is a scenic drive within Custer State Park. This is not to be missed! I enjoyed the beautiful scenes of the landscape. On Iron Mountain Road you come into these one lane tunnels, make sure you honk before entering, on the last tunnel you enter you see an awesome view of Mt. Rushmore. Our family stopped and took some beautiful pictures of that.
Another thing we enjoyed in Custer State Park was the Wildlife Loop. We did this loop twice. The first time we went we did not see too many wildlife. After talking to some locals they suggested to go either early in the morning or in the evening. So later on we went back but this time around 6:30 in the evening. We saw tons of buffaloes roaming the land! We pulled off of the road and just spent time watching these amazing animals. My son thought it was pretty cool when the herd walked right in front of our vehicle.
The Wildlife Loop is worth it, but my advice is to go in the evening. You will see buffaloes.
Lastly, don't leave Custer State Park without driving on Needles Highway! That is fun ride. There are very sharp turns, steep inclines and declines, one lane tunnels, and very narrow roads. Our family enjoyed Needles Highway. On Needles Highway there are unique rock formations. Beautiful scenery. If you go on Needles, just remember to drop down to a lower gear, those roads are steep and you don't want to overheat your brakes.
