Location & getting there
The observatory is in the North America region, in the United States, on the edge of the Black Hills National Forest northwest of Rapid City, South Dakota. The forested, low-population setting away from the city helps keep the skies dark for observing.

See your named star from here
Star parties like the ones held at Hidden Valley are exactly the kind of gathering where a named star gets its moment. If you've named a star with Star Register, bring your certificate's coordinates along and see if the group's telescope can find it. Browse the star catalogue to look up your star first.
Opening hours and public-visit programs vary by season. Check Google Maps for current times before you travel.
