Road to Yellowstone
Donna,
You need to make a comprehensive plan about what you intend to do in Yellowstone. Yellowstone is a
VERY LARGE park. The time of getting to and from somewhere from Yellowstone depends on where you are going and from where in Yellowstone you are leaving.
The roads from Bozeman to Gardener, MT are very good. You should have no problems on these roads. With the trailer it will take 2-3 hours depending on your speed and the traffic.
You plan on getting to Yellowstone about 11 AM. If that means the North Entrance at Gardener, MT then you should plan 2 hours driving inside the park to get to either Fishing Bridge or Old Faithful. Don't plan on camping in Yellowstone if you are arriving after 9 AM unless you want to stay a Mammoth Hot Springs. The campground there rarely fills up before early afternoon. All other campgrounds will probably be full. You can make reservations at some campgrounds. See
www.nps.gov.
When you leave Yellowstone, if you are leaving from Fishing Bridge, plan on 2.5-3 hours to Cody and another 2 hours to Thermopolis. Speed limits inside the park are 45 MPH. Don't plan on averaging more than 30 MPH. Animals, terrain and people will assure that you don't go very fast. If you camp at Mammoth and leave from there to go to Cody plan on 4.5-5 hours to Cody.
Once you leave Cody, you should be able to drive near the speed limit most of the time. Mapquest has driving time from Thermopolis to Buffalo as 3 hours. This is probably accurate for a car, you might plan on 3.5-4 with the trailer. From Buffalo to Rapid City is all I90. Speed limit is 75 MPH. I drive my RV at 65 on I90, I don't know how fast you will want to go.
ALL of Wyoming consists of rolling hills. It is windy a lot once you get east of Buffalo. Your tow vehicle may not be able to maintain your cruise speed on the uphill side of many grades. The wind may make driving slower than the speed limit seem prudent. It is 210 miles so depending on how fast you drive and how steady you stay at it, it will take 3.5-5 hours from Buffalo to Rapid.
As you can tell, Thermopolis to Rapid City is a long ways. You can drive it in a day but it might be a
long day. :laugh:
