Cerro de la Cúpula is a high mountain pass at an elevation of 2.806m (9,206ft) above the sea level, located in the Mexican state of Baja California.
The pass lies within the Sierra de San Pedro Mártir National Park. The road to the summit is asphalted. It’s pretty steep. At the summit there’s a optical telescope built in 1971 called the National Astronomical Observatory. The observatory is the second most important in Latin America. It is open for tours after 10 am and until 1:00 pm on weekdays, at the end of the paved road. It’s now known internationally as one of the best sites on Earth from which to view the heavenly bodies thanks to extremely low light pollution and relative humidity, low atmospheric pollution, generally clear skies and relatively little radio interference.
Do not travel this pass in severe weather conditions: frequent rainstorms and several snowstorms. Avalanches, heavy snowfalls and landslides can occur anytime, being extremely dangerous due to frequent patches of ice. Temperatures vary drastically throughout the park according to elevation due to dramatic topological changes. It has a well-deserved reputation for being dangerous because of unpredictable snowstorms and blizzards, and driving under these conditions, can be extremely challenging. During the winter in the extreme high elevations large amount of snow accumulates while in the summer the lower elevations exceed 100 °F (38 °C).
