Climbing towards the famous Mount Wilson Observatory from La Canada Flintridge offers an iconic Los Angeles cycling experience, taking you high above the basin into the San Gabriel Mountains for spectacular views. You'll climb via the Angeles Crest Highway before turning onto Mount Wilson Road for the final section, covering a very long approximately 19 miles and gaining around 4,500ft to reach the summit area near 5,700ft elevation. You'll climb moderate gradients averaging 4-5% making this a significant test of endurance over power. While the mountain scenery becomes increasingly impressive, be prepared for potentially very heavy and fast recreational traffic on the Angeles Crest Highway section, demanding your vigilant attention.
