The town of Julian, known for its local tourism and agriculture, is a good place to visit for stargazing and planetary viewing. The eastbound drive to Julian takes about an hour from El Cajon via Interstate 8 and State Route 79, or from Escondido via State Route 78. The two other Dark Sky Places are Anza-Borrego Desert State Park and Borrego Springs, both located just under 100 miles northeast of San Diego.

The best way to see the planets is to face south just a few hours after sunset. Venus and Saturn will be found in the southwestern direction of the night sky, according to astronomers. Face south to spot Jupiter and turn toward the east to view Mars. Experts say that a seventh planet, Mercury, could join the parade toward the end of February, before the planets end their alignment.
