LOS ANGELES (KTLA) -- Prince William and his wife, Catherine, visited polo grounds in Santa Barbara Saturday afternoon and a swanky Hollywood reception that night, but on Sunday, the couple bid farewell to Southern California.

The duo departed from LAX around 3:30 p.m. Sunday after spending the day in one of the poorest areas in Los Angeles.

An escorted motorcade took the royal couple to the Skid Row area of downtown Los Angeles -- near 6th and San Pedro Streets -- where the affluence of Saturday's events were replaced with the bleakness of poverty.

William and Catherine visited Inner-City Arts, a non-profit organization that provides free art instruction to kids living in poverty. The royal visit is meant to highlight William's interests in assisting homeless youth and promoting the arts.

The royals met a group of third-, fourth- and fifth-graders inside Inner-City Arts, after the students greeted them with a welcome banner painted with ladybugs, butterflies and flowers.

William and Catherine took time to paint with the children before leaving just after noon.

The couple left to attend a job fair for veterans sponsored by ServiceNation: Hiring of Heroes our at Sony Studios in Culver City before leaving Southern California today on a 3 p.m. flight from LAX.

The royal couple started out their first full day Saturday at the Santa Barbara Polo Club, where the prince will play in a $4000-per ticket charity polo match to benefit the American Friends of the Foundation of Prince William and Prince Harry.

About 400 persons had been expected to buy such tickets, ensuring at least $1.6 million being raised for charity.

Prince William and his polo team won a round-robin match Saturday, garnering them a sterling silver and gold trophy -- weighing 14.7 pounds in the precious metals -- after he scored four goals in the final game. His team won the pivotal game 5-3.

Catherine, awarded the trophy cup to William and his three teammates after the royal couple exchanged congratulatory kisses on both cheeks. She also gave Tiffany gifts to all 12 polo players who played on the three teams participating in the six chukkars, or six periods, of Saturday's play.

After spending the day in Santa Barbara, the pair returned to Los Angeles, where they are staying, and spent the evening at a black-tie dinner and reception hosted by the British Academy of Film & Television at the recently renovated Belasco Theatre in downtown L.A.

The event will honor 42 up-and-coming British talents in film, television and video games.

On the red carpet, Catherine once again wowed the crowd in a dress by Alexander McQueen.

William is the president of the organization.

The couple spent their first evening Friday at a business event supporting U.K. Trade and Investment, followed by a reception at the British Consul-General residence in Hancock Park.

Dame Barbara Hay's 7,247 square foot house on June Street has seven bedrooms and bathrooms.

The royal newlyweds were greeted at the airport Friday by Gov. Jerry Brown; his wife, Anne Gust; Mayor Antonio Villaraigosa; and Britain's ambassador to the U.S., Sir Nigel Sheinwald.

The LAPD said safety is their top priority during the royal couple's visit.
