Roads to the Observatory:

Check the homepage for closures. We do our best to keep it current as things change.

Be aware of winter conditions in the mountains before driving up. After winter storms, like the one on Dec 5-6, the upper roads may have lingering patches of black ice, which can contribute to an accident, and recently did. This is especially true on Red Box Road from the Angeles Crest Highway (2) up to the Observatory. This road is on the north side of the mountain and often receives little sun to melt the ice. Please drive it with caution.
