Six L.A. Museums Are Still Open at 7:30 P.M. We Ranked Them.

One test decides the order: a regular weekly night that runs to 8 p.m. or later, and what it costs to walk in at that hour.

Six museums in Los Angeles County keep a regular weekly night that runs to 8 p.m. or later. One of them runs to 10, six nights a week, and charges nothing at the door. The rest of the county hands your evening back and locks up: the Hammer at 6, the Natural History Museum at 5, the Autry on a weekday at 4, which is a lunch break with a gift shop.

We read the posted hours and admission pages of more than twenty Los Angeles County museums on September 6, 2026, and applied one test: in an ordinary week, with no gala, no members' preview and no ticketed after-party, do the doors stay open until 8 p.m. or later? Six cleared it. They're ranked below on how much of the evening they actually hand over, and what it costs to be inside at that hour.

The pattern that fell out of the reading is the most useful thing on this page, so here it is up front: every museum in this county that keeps its doors open until 8 or later is free, or free if you live here, or five dollars. The ones charging $25 and $30 are shut by six.

1. Griffith Observatory — 10 p.m., six nights a week, and nobody takes your money at the door

This isn't close, and the gap is measurable: an hour later than second place, five more nights of it than second place, and a $0 admission that the city has never charged. The Observatory's own hours page posts noon to 10 p.m. Tuesday through Friday, 10 a.m. to 10 p.m. Saturday and Sunday, closed Monday. On the day we read it, that same page put Sunday's sunset at 7:14 p.m. — so the building is open for the better part of three hours after dark, which is the entire argument for an observatory.

The free part is not a promotion. Admission, the exhibits and the public telescopes cost nothing; the one thing with a price is the Samuel Oschin Planetarium, and its show page lists $12 for adults 13 to 54, $10 for seniors 55 and over and for students and teachers with ID, $8 for children 5 to 12, and free for children under 5 on a lap. Tickets are sold only on site, only for that day's shows, in blocks — the last one on both the weekday and weekend schedules starts at 8:45 p.m.

Two more things the posted pages give you and no aggregator will. The Observatory runs a Public Star Party roughly once a month with local telescope clubs on the lawn; the September edition is listed for September 19, 2:00 to 9:45 p.m. And on parking, the Observatory's own wording is worth reading before you drive up: "There's paid parking near the Observatory and free parking downhill." That sentence is doing a lot of work on a Saturday, and it is the only honest thing anyone has ever written about parking in Griffith Park.

2. The Getty Center — Saturday until 9, on the one night the parking is free

The Getty runs a single late night a week and gets second place anyway, because of what it does with that night. Per the museum's own visit page, the Center is open 10 a.m. to 6:30 p.m. Tuesday through Friday and Sunday, 10 a.m. to 9 p.m. on Saturday, closed Monday. Admission is free and requires a timed-entry reservation.

Then read the parking line on the same page: $25 per car, $15 after 3 p.m., $10 after 6 p.m. — and free on Saturdays after 6 p.m. The one evening the galleries stay open three extra hours is the one evening the hill stops charging you to be on it. Whether that alignment is generosity or arithmetic, it means a Saturday-night Getty visit is the only trip on this page where a car costs nothing.

One correction to a common assumption, since the two share a name and nothing else: the Getty Villa in Pacific Palisades posts 10 a.m. to 5 p.m. daily, closed Tuesday, on that same site. It has no evening at all.

3. LACMA — Friday to 8, and if you live in this county it's free from 3

LACMA's hours page puts Friday at 11 a.m. to 8 p.m., with Saturday and Sunday to 7 and everything else to 6; Wednesday it's closed. That Friday close ties three other museums at 8. What promotes LACMA over two free ones is the second page.

LACMA's ticket table gives people residing in L.A. County with valid ID free admission after 3 p.m., Monday through Friday. Do the subtraction on a Friday: that's five consecutive free hours, 3 to 8, for anyone who can produce a county address, at the only museum on this page whose evening otherwise carries a full-price ticket. The same table prices an adult from outside the county at $30, and an adult inside it at $25 before three o'clock, which makes the ID the most valuable thing in your wallet on a Friday afternoon in Miracle Mile.

4. Museum of Jurassic Technology — Thursday, 2 to 8, five dollars suggested

Here's the placement worth arguing about, and I'll defend it in one line: a $5 room of dubious dioramas in Culver City finishes above two free museums downtown, because on the night in question it is the cheaper evening.

The museum's hours and donations page posts Thursday from 2:00 p.m. to 8:00 p.m., and Friday, Saturday and Sunday from noon to 6:00 p.m. Suggested donations are $5 for adults, $3 for people aged 12 to 21, students, anyone 60 or over and the unemployed, $2 for disabled visitors and for active service personnel in uniform, and free for children under 12. The same page says the Tula Tea Room and the Borzoi Kabinet Theater open an hour after the front desk does and close an hour before it — on a Thursday that's 3 to 7 — with complimentary tea and cookies, and films screening hourly.

The structural point is the schedule, not the price. Thursday is the only day of its week that starts in the afternoon, and it's the only late night in this ranking built as an evening rather than extended from a morning. The downtown pair open their Thursday at 11 a.m.; this one doesn't unlock until 2, which is the difference between a night out and the end of somebody's day off.

5. The Broad — Thursday to 8, free at the door, $19 in the garage

General admission at The Broad is always free, its visit page says so in those words, and the Thursday hours run 11 a.m. to 8 p.m. — the museum's only late night, against 11 to 5 on Tuesday, Wednesday and Friday and 10 to 6 on the weekend.

Fifth place is about the second number on that page. The Broad's own parking rates are $19 for three hours with museum validation, $7 for each additional 15 minutes, a $29 daily maximum, and a $19 flat rate after 5 p.m. on weeknights. So the free museum's Thursday evening opens at $19 the moment you park under it, which is nineteen dollars more than the Getty's Saturday and fourteen more than the entire suggested donation in Culver City. The art is free. The evening isn't.

6. MOCA Grand Avenue — the same Thursday, the same 8 o'clock, also free

MOCA's visit page puts MOCA Grand Avenue, 250 South Grand, at 11 a.m. to 5 p.m. Tuesday through Friday with Thursday running to 8 p.m., 11 to 6 on the weekend, closed Monday. General admission is free — the page credits Carolyn Clark Powers by name for it — and advance reservations are recommended.

Sixth is not a knock on the museum; it's the calendar. MOCA and The Broad hold their late night on the same weeknight, on the same street, so downtown's two free museums split one evening between them instead of covering two. And the Geffen Contemporary, which would otherwise be the third door, is closed for deinstallation and installation per that same page, with a reopening tied to its performance series this month.

The once-a-month tier, which is a different promise

Two more places run real evenings that failed the weekly test, and both are worth a calendar entry. Craft Contemporary on Wilshire opens the first Thursday of every month from noon to 8 p.m., per its visit page, against 11 to 5 the rest of the week; admission is $12 for adults, $10 for seniors 65 and over, students and educators, free for anyone 12 and under and for EBT holders, and Sunday is pay-what-you-wish. The Autry, meanwhile, advertises Autry After Hours on select weekday evenings from 6 to 9 p.m. on its visit page — the same page that posts Tuesday-to-Friday hours of 10 a.m. to 4 p.m. A museum that shuts at four and then throws its own night party is telling you something about who it thinks its weekday visitor is.

Who isn't on this list, and when they actually close

The near misses are the useful part, because most of them close earlier than you think. The Hammer is free and runs 11 a.m. to 6 p.m., Tuesday to Sunday. The Academy Museum is 10 to 6, Wednesday through Monday, with a "Last Looks" price of $18 for adults after 4:30 p.m. The Petersen is open seven days, 10 to 6, and stops checking people in at 5:30. The Natural History Museum posted 9:30 to 5 on the day we read it, and gives L.A. County residents free admission from 3 to 5 p.m., Monday to Friday, on site only. The Skirball is noon to 5 on weekdays, 10 to 5 on weekends, with box-office check-in closing at 4:30 — and free parking, which is rarer than a late night. The Grammy Museum tops out at 6 p.m. on Saturdays. The Museum of Latin American Art in Long Beach, LA Plaza de Cultura y Artes and the free Wende Museum in Culver City all close at 5.

One absence is temporary and worth marking on a 2027 calendar. The Japanese American National Museum's visit page says the JANM Pavilion is closed for renovation, and posts the hours it will resume beginning January 23, 2027: Tuesday through Sunday, 11 a.m. to 5 p.m., open until 8 p.m. on Fridays — with admission free on Fridays after 5 p.m. When that door reopens, this ranking gets a seventh entry and downtown gets a second free night.

What the closing times are actually telling you

Line the six up and the money runs backwards from what anyone would guess. Four of them — Griffith, the Getty, The Broad, MOCA — charge nothing at the door to anybody. The fifth asks five dollars and will take three. The sixth hands its evening to county residents for free at three o'clock and charges everyone else $30. Meanwhile the ticketed doors we checked are the ones that shut early: the Academy Museum's $25 closes at 6, the Grammy Museum's $22.50 tops out at 6 on a Saturday and 5 the rest of the week, and the Autry's $20 is done at 4.

If your favorite isn't here, it closes before 8, it runs its evening once a month, or its website wouldn't tell us: the Norton Simon answered our requests with a browser check and the Fowler with an empty page, and we don't print hours we couldn't read. We checked all three. The one that costs nothing and runs latest is open until 10, every night but Monday, with the telescopes out on the lawn.
