The man teed off with three friends on the second hole of the Pala Mesa Resort Golf Course in northern San Diego County at around 10 a.m. and then got into his cart.
The vehicle veered off the concrete pathway, traveled down a 25-foot embankment and went over the edge of a cliff, California Highway Patrol spokesman Tom Kerns said.
The recently retired real estate agent from Irvine was ejected shortly before the cart hit the road beneath the cliff and died on impact, Kerns said. His name was not immediately released.
No one else was involved in the crash.
Investigators will inspect the golf cart for mechanical failures, Kerns said.
