Echo Mountain, Mountain summit in San Gabriel Mountains, California.
Echo Mountain rises 3,210 feet above Altadena, featuring steep trails through Rubio and Las Flores canyons in the Angeles National Forest.
The Mount Lowe Railway transported visitors to Echo Mountain's White City resort complex, which included a 70-room Victorian hotel from 1893 until 1900.
The mountain derives its name from voice repetitions in Castle Canyon, where multiple echophones were installed for visitors to test sound projection.
The Sam Merrill Trail starts at Lake Avenue's end, gaining 1,400 feet elevation over 5.5 miles round trip through a series of switchbacks.
Foundation ruins of the former Echo Mountain House and railway structures remain visible at the summit, along with informational plaques about the site.
