Mount Wilson Toll Road

Mount Wilson Toll Road is a hiking trail that climbs steeply through the San Gabriel Mountains with exposed sections, shaded forest passages, and scattered rest areas along the way. The path shows signs of its original construction with stone work and natural features that shape how hikers move through the landscape.

The route was created in the 1890s to provide mountain access, with the path serving both hikers and riders who paid fees for passage. The road became an important link between the valley and the mountaintop installation.

The trail connects to Mount Wilson Observatory, which has made significant contributions to astronomical research and scientific discoveries since the early 1900s.

The climb takes several hours on a steep path, so start early and bring plenty of water and snacks for energy. The terrain is uneven and exposed to weather, so sturdy shoes and layers of clothing help with comfort.

Sections of the original route built over a century ago remain visible with stonework and structural details intact. Hikers walking the path can observe the construction techniques that were used to create mountain access in that era.
