Es un lugar para ir una sola vez en la vida. Si te toca ir en noviembre anda en noviembre. Trata de llegar cerca del mediodía. Antes hay neblina y solo se ve la base de la montaña.

Definitely Custer Park with lots of buffalo. I would highly recommend Needles Highway. It is absolutely gorgeous. I would recommend planning to see the Mt Rushmore lighting ceremony at night.

Also you must go to Crazy Horse Monument

My recollection is some people had dogs on 6 foot leashes in the parking areas. I also saw elderly people carrying small dogs in thier arms. A small hill is the last thing before you enter the park (construction) and a ranger is there to greet you. He will let you know if you can do so. I do not remember any designated areas for pets to wander or potty.

My guess would be probably not. Mt Rushmore is not that close to anything. If you're traveling in the Black Hills it would be advisable to have a vehicle as attractions are spread out.

Yes. Rapid City is the nearest big city to the monument (30-40 minutes) so rates there are about 1/3rd lower than in Keystone

As with any heavily traveled tourist destination reservations are a must in the spring and summer.

Hard to answer a question like this. What is normal? We went twice, once in the evening to see the lighting ceremony and once during the day. Both trips were a couple of hours each. You can rush through it in 15-30 minutes, but to really get an understanding of what it took to build it, how it's maintained, all of the people behind the scenes, and then to physically do some hiking around - you need to spend several hours. If you're just checking it off a list with a limited time frame - give yourself at least an hour. Otherwise, take your time and take in the majesty!

If you have a service dog then yes. All other dogs are not permitted.
