Take Exit 109 and take a RIGHT toward Ellensburg. Proceed north for a few miles through the "hotel district" and then historic downtown. Take a RIGHT on University avenue (in front of Jack in the Box) and continue east for a few blocks. Turn LEFT on Wildcat Way. Take a RIGHT at the first stop sign (11th Ave.) and park in the small lot on the immediate right (H-6). Accessible Parking spots and drop off points are available nearer to the building, accessed by continuing on 11th after the lot. If that lot is full or closed, continue on Wildcat Way for a block and park in the first large lot on the left near Campus Police (O-5). From the small parking lot, head away from Wildcat Way (east) from either the top or the bottom of the lot. Discovery Hall is two buildings in, most easily recognized by the large telescope tower on the southwest corner. Enter any door and follow signs to the Lydig Planetarium. You have arrived; welcome!
Approaching from the South: From the South take Interstate 84 until it joins Interstate 90 Westbound. Follow the directions above.
