Due to a series of disasters in the early 1900s, including fires, floods, and wind storms, this area was brought to ruin. Several remnants of that era, in the form of ruins, can still be found on the summit. Combined with the stunning views, this makes it a must-see in the area.

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.
