May 4, 2025, Mt. Wilson Climb

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.

Mount Disappointment stands at 5,963 feet above sea level. The summit was actually flattened in the 1950s to accommodate a Nike missile site, which was decommissioned in 1965. There are currently multiple telecommunications towers at the summit, which are still in use. Mount Disappointment got its name in 1894 when USGS surveyors sighted it and thought it was highest peak in the area. When they reached the summit, however, they discovered that the neighboring peak, San Gabriel Peak was about 170 feet higher, and were disappointed. Despite the 19th century surveyor's disappointment, this peak is a great destination and offers fantastic views of the San Gabriel Mountains front range.

A challenging but manageable ascent takes you up to Clamshell Peak, residing at 4,360ft. The trail is fairly exposed all the way up, so plan heat conditions accordingly. You can also start this hike from Monrovia Canyon Park, but checks trail conditions prior to making the trek as wildfires have implemented temporary closures in the area. Bears are also present in the area. https://www.cityofmonrovia.org

The summit of Echo Mountain has the ruins of what was a resort complex for the Mount Lowe Railway circa 1900. A cable car took visitors up from Pasadena below to this summit where a grand hotel and recreation facilities existed. The ultimate plan was for the Mount Lowe Railway to proceed to San Gabriel Mountain but in the early 1900's a fire destroyed the facility.
