Frequently asked questions
- Is Lick Observatory open to visitors right now?
- Yes, but with a catch: the historic Main Building is closed for ongoing storm-damage repairs. The Visitor Center and gift shop (temporarily in the historic Dining Hall) are open Thursday-Sunday noon to 5pm, the East Grounds are open daily 9am-5pm, and Great Refractor dome tours still run. Check lickobservatory.org before driving up.
- Can I look through the telescope at Lick Observatory?
- Not during regular daytime visits — you'll see the Great Refractor up close on a tour, but looking through it happens only at the ticketed summer evening programs. Those are genuinely special and worth planning a trip around.
- Is there food or gas at Lick Observatory?
- There's a gift shop with light snacks but no restaurant, and there is no gas station anywhere on Mount Hamilton. Fill your tank, bring water and food, and note that weather up top runs much colder than San Jose — it snows some winters.
- Is the Mount Hamilton drive worth it just for the views?
- On a clear day, honestly yes — you see the whole Santa Clara Valley and, from the summit, deep into the Diablo Range. But pick a Thursday-Sunday so the Visitor Center and tours are running; the drive is too long to arrive at locked doors.
- How much does it cost to visit Lick Observatory?
- Daytime visits are free, including the hourly tours of the 36-inch Great Refractor dome. Evening telescope-viewing programs in summer are ticketed and sell out fast — they go on sale in spring via Eventbrite.
- How bad is the drive up Mount Hamilton?
- It's about 19 miles and an hour from San Jose, with something like 365 turns — it was graded gently for horse-drawn wagons, which means endless switchbacks. Anyone prone to carsickness should sit up front. The road is narrow but paved and fine in a regular car; watch for cyclists.
- Is James Lick really buried under the telescope?
- Yes, actually. James Lick, once the richest man in California, is entombed beneath the pier of the Great Refractor, per his wishes. The tour guides tell the story well — he originally wanted a pyramid bigger than Giza.
- When are the Great Refractor tours?
- Free tours run every hour on the half hour near the Gift Shop during Visitor Center hours (Thursday-Sunday, noon-5pm). The 36-inch refractor was the largest telescope on Earth when it saw first light in 1888.
