The Observatory is more than 20 miles from downtown San Jose along Mt. Hamilton Road at
an elevation of 4200 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 4209 feet, weather on Mt. Hamilton may be cool and changable, 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.
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.
Directions to Mt. Hamilton
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, 680, take
Alum Rock Avenue exit from Interstate 680 north. Turn right onto Alum
Rock Avenue. Take another right on Mt. Hamilton Road (California Route

as the road is good, but winding.
From the east, take Interstate 580 west to Interstate 680 south. Then
follow the directions above. Alternatively, you may take 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,

Please Do Not Visit at Night!
- Buildings are locked
and astronomers are working at the darkened telescopes. There is nothing to see
and nobody available to show you around.
- Telescopes require the darkest possible conditions to detect the faint light from celestial objects. The success of our work relies upon minimizing lights
around the observatory at night.
