  • This Observatory is located near Pasadena in about 1700 meters above sea level and we will get you through a beautiful scenic mountain road that is part of a national park. The area of the Observatory is closed by a gate that opens to the public at 10 in the morning. By logging in you arrive at a large square for parking which costs 10 $ per day. Parking on the cosmic cafe, only on Saturdays and Sundays, the days when the restaurant is open. Always at the cafe you buy the ticket of the tour for only $ 15 each. The tour starts at 13 precise with meeting point from the cafe and takes about two hours and are performed by volunteers: wonderful people and very helpful. The tour begins with a walk in the Woods where the guide makes several pauses to explain in detail the history of the Park and the Observatory. Along the way we stop and it gets inside the domes where there are telescopes. The Guide, always gracious, explains in a simple and accurate technology, history and discoveries made by each telescope. We were also shown a practical example sunspot profiling by an elderly but very experienced technician working in the facility. The tour culminates with a visit to the telescope by 100 "who was for many years the largest in the world having allowed the modern astronomy to discover a large number of stars, constellations, etc. The visit is allowed to take pictures and the thrill of seeing such instruments is truly remarkable.

  • Staggering views to be seen. Incredibly empty and unspoilt. worth going to see the amazing scenery. Only about an hours drive from LA. 
  • Did an overnight viewing session a few years back. Saw nearly every planet and many deep sky objects. This observatory is in God's country.
  • The hike to the observatory is very pleasant and challenging enough. The view at the top is fantastic views of LA. You can go up to the observatory and look at the stars. There is also a restaurant that you can grab something to eat.
  • Fantastic views, great hiking, far away enough to feel like there is nothing around you but still a stones throw away from the city. This place is full of history.
  • I love visiting this place. There is so much to see as you wander the grounds. The friendly volunteer staff are generally happy to show you around.
  • I love the view. You can see so much of LA. Gotta check out the telescopes also!
