The area is heavily wooded and lush with vegetation, including coast live oaks, California sycamores, various species of Eucalyptus, and many ornamental trees.
Due to its humid climate and the surrounding dense suburban development, the canyon is less threatened by wildfires than other communities within and adjacent to the Santa Monica Mountains.
[3] Abbot Kinney, the developer known for founding the nearby community of Venice Beach to the south, established an experimental forestry station and planted eucalyptus trees in the lower canyon, which still remain.
The clubhouse and adjacent recreational elements, including a swimming pool, baseball diamond, and tennis courts, were donated to the city in the early 1950s.
The nearest commercial buildings are in lower Santa Monica Canyon at Pacific Coast Highway, and consist of several shops, bars, restaurants, and a gas station.
Residences designed by Lloyd Wright, Richard Neutra, Craig Ellwood, Ray Kappe, Moore Ruble Yudell, Marmol Radziner and other prominent architects are located in the canyon.
During the 1980s Steve Tisch, a film producer and Loews Hotels heir, fought a five-year battle against local residents for expanding his large property to include a public city street, and eventually lost the case.

[10] In September 2007 a judge ruled that the new addition to the Beglari residence was 14 feet (4.3 m) over the setback requirement and closer to the Greentree Road than permitted by the Los Angeles Municipal Code's zoning law.
