The observatory at SUNY Oneonta is located at College Camp, approximately 2 miles north of campus. The get there, take East St north from campus about 1.5-2 miles until you see a sign on your left announcing College Camp. The road to the camp is just past this sign on the left. Take the road through the white gate and all the way up the hill to the top. You will see the observatory domes there, in a very large clearing.
