Stand on the walls and balls roll uphill. The 40-minute tour is great for the kids. They haven't updated much from when I was there 15+ years ago but still was something to bring the kids too.

You will walk away scratching your head wondering what just happened. A great place to stop that will have you talking about for years to come.

Supposedly the tour is really cool,but it was busy so we didn't go on the tour. We looked around and left. However we looked up You Tube videos and it looks like it could be fun,but it is a little prucey.

Tour guide Isabel was wonderful! She was patient, funny, and warm with all of the guests on a cold, blustery day. I highly recommend this to families or people of all ages! I've never been anywhere like it!

On a return visit to SD, the husband and I decided to try something we haven't seen before. This was definitely it! The tour guide was an absolute hoot! And the tricks, teases and stories she told were hilarious...and strange. Definitely a must do!

My 11 year old granddaughter had a blast, and in fact wanted to go back. Warning - if you suffer from motion sickness, you may feel it. Definitely worth a visit.

I wouldn’t think so. There’s hand rails and stairs that are all wood. Possibly slippery though. We didn’t experience rain when we visited.

Yellowstone to Rapid City (8 Replies)
Arriving in West Yellowstone 9/13 early afternoon. Plan to do the lower loop 9/14 and the upper loop 9/15, proceeding to Jackson for 2 nights. Then to Cody for 1 night, Sheridan for 1 night, then to Keystone for 2 nights, then home from Rapid City on 9/21. 1. I know it's been recommended to spend more time doing Yellowstone, but this is what we have. Will we be able to see the major attractions taking 1 day for each loop? 2. How long will it take from Jackson to Cody (back up through...More

1) Yes, you can do each loop in a day. There's not that much mileage, just many places to stop along the way. 2) Inside the park, I believe the speed limit is 35 mph, so don't expect to get anywhere quickly. Probably about 4 hours from Jackson to Cody going through the park. 5) The leaves tend to change pretty early in Yellowstone. You're probably looking at last week of September/first week of October. 6) You can see Crazy Horse from the road.

Geysers: We will spend two whole days in Yellowstone at the end of September--doing the lower loop the first day and the upper loop the second then down to Jackson. I know the mileage is not great and that the speed limit is 35-40 mph, but how much time does one have to allow to see Old Faithful (for instance) do its thing? Is there a time table and where is that found? What about the other geysers? Jenny Lake: Unfortunately, I am unable to hike to Inspiration Point, but would it be...More
