Copernicus Peak is the hightest point in San Jose and Santa Clara County. Hiking is the only way to get to the summit of Copernicus Peak but biking up Hamilton Road to Lick Observatory is a challenging addition to the hike. Copernicus Peak is clearly visible from Lick Observatory which houses the Shane Telescope. In the fifties a transmitter was set up on Copernicus Peak. The transmitter was part of a group of transmitters used as a dispatch which had about 40 frequencies, including police, fire, health and medical, Department of Transportation, and paramedics. The main landmark of Copernicus is the firetower on the summit. If you climb the stairs you can get some great views. Copernicus Peak, being the highest point in Santa Clara County, is a good hike for county highpointers. The main attraction of Copernicus Peak isn't that it's a great hike but the fact that it is a county highpoint.

Getting There

From I680, exit and head north-east Alum Rock Avenue. Continue approximately 2 miles and turn right onto Mt. Hamilton road. Drive the 19 miles up to Lick Observatory and park there. From Lick Observatory, follow San Antonio Rd east, pass the water tanks and head for the lookout tower. There will be a gate just off the road about 0.25 miles from the observatory. If you have permission go through the barbed wire (the barbed wire has a huge gap in it that anyone can get through) and continue up the steep road. Its about another 0.25 miles until you will get to the head of several trails which are just higher than a building and port-a-poty. Choose the one on the far right and follow it for about 75 yards until you get to the firetower.

Red Tape

Copernicus Peak isn't legally accesible. Warning signs are often disregarded because it's a county high point. Actually getting in trouble up there is a rare occurence. If you go into Lick Observatory's main building you can ask where the officer on patrol is and ask him for permission. There are no fees or permits required to get to any part of Mt Hamilton. There is free parking at Lick Observatory and no passes are needed.

When To Climb

The seasons in the area around Copernicus Peak are fairly mild. Winters usually stay above forty or fifty degrees. Summer can be in the nineties and that could be a problem if your biking up Mt Hamilton Rd. It snows often in the winter and the roads do close sometimes. Spring and fall are the best seasons to attempt Copernicus Peak.

April through September campsites are open daily and in March and November they're only open on weekends. The campsites are closed for winter from November to February.
