Locally there are the Will Rogers State Historic Park, and Will Rogers State Beach.
The SHP is off Sunset Boulevard in Pacific Palisades, and included his ranch house, horse stables, corrals, polo field, and surrounding acreage, all of which burned in January during the Palisades Fire. All horses were evacuated to safety. The hiking trails — through burned chaparral — are all that remains.
The SB is on Pacific Coast Highway and Temescal Canyon Road, and has volleyball courts, and lots of parking. (Both sides of Temescal Canyon burned in the Palisades Fire.)
When my brother and I were little the family would go to Will Rogers Beach (no volleyball courts then).
