Directions to Lick
 

Lick Observatory is located on the summit of Mount Hamilton in the Diablo Range east of San Jose. In San Jose, from either highway 101 or highway 680, exit at the Alum Rock Avenue interchange. Go east on Alum Rock Avenue (which is also state highway 130) for 3.6 miles from route 101 or 2.2 miles from route 680. Turn right on Mount Hamilton Road (which continues state highway 130). Alternatively, from highway 101 take Tully Road east to Quimby Road, following Quimby into the hills for several miles, until it joins Mount Hamilton Road. Allow at least 1 hour from San Jose, and please drive carefully - the road is good, but steep and winding.
