We are located on the UW-Eau Claire campus, at the north end of Phillips Science Hall, just inside the doors (inside the bird museum).
Follow the directions to the UW_Eau Claire Visitor Center, but go past it and follow Roosevelt Avenue a little farther as the road turns into the parking lot behind Phillips hall. The planetarium is on the ground floor of Phillips Hall, near the main doors (opposite side of the building from the parking lot).
View maps of the area. Look for free parking on Saturdays and after 6pm.
