Ontario airport is w-a-y out there far from LA. It's not just the miles, but the driving time.
Most of the good stuff in LA is on its west side.
East LA is ghetto, miserably hot, smoggy. It's basically Mexico in a continuous band from downtown LA for about 40 or 50 miles or more toward the east past Whittier, La Habra, Pomona, and further east. I do not exaggerate.
South Central LA is ghetto too. That's where the race riots happen. LA Colosseum & points south for about 30 miles until Long Beach.
The San Fernando Valley area of LA is hotter 'n hades & the smog hangs in there this time of year. But not too bad there in winter.
From Ontario you'd probably be happier going down into the Orange County area. That's where a lot of LA people go to escape LA.
Irvine, Laguna Beach is especially pleasant, Newport Beach, Balboa Island. World class shopping & entertainment, restaurants, universities, etc. Everything's newer, nicer, cleaner and more wide-open than in LA.
Here's a loop that'll tour you through the best of LA:
On the LA west side take UCLA as your central reference point.
All scrunched together you have
Beverly Hills across the east side of UCLA,,
UCLA,
Bel Air across the north edge of UCLA,
Brentwood to the west side of UCLA ,
Santa Monica..
There's the fantastic
Getty Museum
free. You
must try to visit. It's the wealthiest museum in the entire world and is really special to see, both for its unmatched collection and its amazing architecture. The one atop the mountain over Brentwood (just west of UCLA) is new (<-this one), the other smaller one in Malibu is cool, built as a replica of an ancient wealthy villa found under Mt. Vesuvius lava.
Free.
From there continue driving west on out
Sunset Blvd. to the beach.
Stop at the
SRF Lake Shrine
nd spend an hour walking around the lake just before Sunset meets the beach. Some cult owns it but anyone can go in
free and enjoy the place. I used to visit there sometimes when I got too frazzled in grad school. I always left there feeling deeply peaceful, calmed. It's beautiful, and
free.
Continue on Sunset a few hundred feet past Lake Shrine to dinner at
Gladstones
where you can eat on the patio above the beach watching the waves. A little bit expensive but worth it.
Or the other Getty Museum in Malibu is just a mile up PCH (Pacific Coast Hwy) from Gladstones.
Along the south-east corner of the Santa Monica area is a fun night entertainment place called
McCabes.
The top players hit that intimate fun place.
Loop ends here.
Other:
To the east of Beverly Hills is an interesting day-visit place called
La Brea Tar Pits
worth 2 hours seeing the fossils of ancient animals still being recovered & displayed there.
To the north is
Griffith Park
(the big dry-looking mountain in the center of LA) where you can see the Griffith Observatory & Science Museum where you push buttons, pull levers, etc., LA Zoo, LA Railroad Museum, LA Cowboy Museum, etc.
Up on the east side of Pasadena is
the famous Cal Tech University,
and just further east is
The Huntington Library, Art Collections, and Botanical Gardens.
That's really spectacular, I love that place, but late February is the time to go (flowers blooming) and it's pretty hot there to enjoy in summers.
You already know the standard tourist stuff like Disneyland, Knott's Berry Farm, Universal Studios, Raging Waters, Catalina Island, etc. but that's out of LA proper.
LA Dodgers.
LA Galaxy & bend it Beckham Posh Spice
LA Angels
LA Lakers
LA Kings
