Maps
If your coming from I-94 turn North through Bismarck and continue north on Highway 83, there will be signs leading you to Cross Ranch State Park. If you go through Washburn, you have gone too far, your about 10 minutes away from the park.
The North Dakota Star Party is located almost dead center in North Dakota. There is a airport in Bismarck that you can fly into and rent a car to get to the star party. From Bismarck Cross Ranch State Park is about 45 minutes to an hour North. You may wish to ask for a more detailed state map if our maps are not detailed enough.
Above is a map of Cross Ranch State Park. Once you arive at the park you can get a better detailed map of the park, but this one should give you a general idea how things are laid out.
