West Mountain Driving Directions
In general the observatory is not open to the public. It is a research facility and will quite often be in use when the road is passable. When driving up the mountain to see the observatory from outside the gate, a vehicle with good ground clearance is recommended. The road is not well maintained and we take no responsibility for anyone traveling up the road to the observatory.
The easiest route to the mountain is through downtown Spanish Fork, UT. Getting off I-15 you will head south toward downtown. At the third traffic light you turn right. This road is 400 North in Spanish Fork. It will go toward the mountain for some distance. After a couple of miles you will come to a four-way stop at Lake Shore. Continue straight and the road will take a sharp right turn after another couple of miles. Take the first left immediately after the sharp right. The sign will point toward Lincoln Beach. Follow this road out to the base of the mountain. As you parallel the base of the mountain you will see a series of telephone poles to your left. The wires will then cross over the road to your right. At the second telephone pole on your right turn left onto the gravel mountain road. It is then a rough, bouncy trip for 5.5 miles up to the observatory. The main road will end at the observatory gates.
