Visitor Activities

Make your trip to Lick Observatory a memorable one with our recommendations.

View exhibits in the main historic observatory building, built in 1888. Note the original oak and marble interior.
Enjoy a short informal talk about James Lick and Lick Observatory history while taking a look at the Great Lick Refractor in the 36-inch telescope dome (no charge). Talks begin at the gift shop, throughout the afternoon starting at 12:30 p.m. continuing until 4:30 p.m., Thursday through Sunday.

Travel Prepared

The observatory is more than 20 miles from downtown San Jose along Mt. Hamilton Road at an elevation of 4,200 feet. The road follows a gradual grade laid out over a century ago for horses and carts. It has many sharp curves and is quite narrow in places.

At 4,209 feet, the weather on Mt. Hamilton may be cool and changeable, so bring a sweater or coat. We do have wheelchair access to the main building from the back.

There are no gasoline or automative services at Mt. Hamilton or anywhere along the road outside of San Jose (or Livermore or Patterson if arriving from the east). Take extra precautions driving up to the observatory: mudslides, rocks, gravel/debris, and wildlife can cause hazardous road conditions. Also, please look out for motorcycles and bicyclists–drive conservatively and share the road.

During the winter the road may be closed temporarily due to snowfall. For current road closure information, Visit the California Highway Information website and enter Hwy #130.

Lick Observatory is located on the summit of Mt. Hamilton in the Diablo Range east of San Jose. To get there from Interstates 101, 280, or 680, take the Alum Rock Avenue exit and head east. Turn right on Mount Hamilton Road (CA route 130) and drive 18.5 miles to the Observatory. From the east, take Interstate 580 west to Interstate 680 south. Then follow the directions above. Alternatively, you may take California Route 130 to Mt. Hamilton from the east, but please allow about 1-3/4 hours from Interstate 5 to reach the Observatory. The road is long and winding, but well-maintained. Take the Patterson exit off Interstate 5, and go west on del Puerto Canyon Road (away from Patterson.) At the Junction Cafe, turn left to stay on California Route 130.

All parking at the observatory is free. Parking spaces are available outside of the main building, and down the hill across from the school.
