"Was amazing. Got a tour of the telescopes. Went up the elevator to the top. Walked around outside on the cat walk. What a view."
Keith LaRoche
"I'm sure this is a beautiful place, however I was only able to get to the gates and not see the top of the mountain where the observatory is. It seems they are randomly open with no real schedule anyone can rely on."
Peter Roberts

The Science Behind San Pedro Mártir
This location is crucial for astronomy and astrofotografía, allowing scientists to study distant galaxies, black holes, and cosmic phenomena with exceptional clarity. The observatory houses several powerful telescopes, including the 2.1-meter telescope inaugurated in 1979, which was once the largest in Latin America. More recently, the Franco-Mexican Telescopio Colibrí has been installed to detect high-energy gamma-ray bursts, the most energetic explosions in the universe.
Beyond its scientific contributions, the observatory plays a role in public outreach, occasionally offering tours and participating in events like capturing total lunar eclipses. Its presence highlights Mexico's significant contributions to space science and exploration, making it a vital hub for understanding the cosmos.
Planning Your Mountain Adventure
Your vehicle is your lifeline here. Ensure it's in excellent mechanical condition before you depart. The nearest car repair shops are hours away, and roadside assistance is non-existent. A full tank of gas is a must, as are any essential supplies you might need. The landscape is often compared to the Pacific Northwest, offering a unique natural beauty within Baja California.

Patience is key, as there can be long waits at the entrance. Checking for any official visiting hours or tour availability beforehand is advisable, though not always definitive.
