The Central Idaho Dark Sky Reserve (CIDSR) is located in central Idaho and encompasses the cities of Sun Valley, Ketchum, and Stanley. Shopping, restaurants, accommodations, and amazing night sky viewing access can be found within and around all three cities. State Highways 75 and 21 provide easy access to and through the CIDSR.


The CIDSR may seem like a remote destination but getting here is easier than you might think. The Friedman Memorial Airport is located only twelve miles from the Reserve and the Ketchum/Sun Valley area. Boise, the capital of Idaho, is just a 2.5-hour drive from the Reserve. Boise offers a larger airport with a wider selection of airlines and flights.


The fact that all three of the main routes into the CIDSR are scenic byways gives an indication of the stunning landscapes found in central Idaho. The three scenic byways meet in the city of Stanley in the heart of the Reserve.


Driving to the CIDSR is popular amongst visitors and residents alike due to the typically friendly road conditions and relative ease of navigating. Because the reserve is over 900,000 acres you have several options on how to drive to the CIDSR.

From the South

The Sawtooth Scenic Byway/ID 75 provides the main access route to the Reserve and to Sun Valley/ Ketchum. North of Ketchum the highway continues over Galena Summit into Sawtooth Valley and to Stanley.

From the Southwest

The Ponderosa Pine Scenic Byway/ID 21 provides access from Boise to Stanley.
