Mount Lee, Mountain summit in Griffith Park, Los Angeles County, US.

Mount Lee is a summit in Griffith Park with a flattened peak about 1,708 feet high, located within the Santa Monica Mountains. Several hiking trails wind through the park to reach the top, where communication towers and equipment occupy the peak area.

The peak was named after Don Lee, who bought radio station KHJ from Harry Chandler in 1927 and later moved his experimental television transmitter W6XAO to the summit. A June 1939 article noted his 20-acre purchase on the mountain top. Television transmissions from Mount Lee ceased in October 1951.

The sign on the slope reads HOLLYWOOD, but it was erected in 1923 as HOLLYWOODLAND, an advertisement for the Beachwood Canyon housing development ordered by developers including Mack Sennett and Los Angeles Times publisher Harry Chandler. The last four letters were removed in 1949. The letters are white capitals set in rows on the scrub-covered upper slope.

The park has multiple entry points and parking areas, with trail maps available at the visitor center to help plan your route. The hike is popular, so starting early is helpful, and prepare for heat, especially during warmer months.

Part of Mount Lee was sold to Howard Hughes, who planned a mansion there for Ginger Rogers; the relationship ended and no house was built. The 138-acre Hughes estate parcel was sold to Chicago investors in 2002, and a 2010 fundraising effort bought the land and added it to Griffith Park.
