Visitor Activities

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

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.
