Field Dossier No. 9 · Classification: Delightful

Pasadena, California

San Gabriel Valley, 10 miles northeast of downtown Los Angeles

A city of roses, rocket scientists and Craftsman porches at the foot of the San Gabriel Mountains. World-class gardens, a stadium with a flea market, and the laboratory that drives the robots on Mars.

Summary of Findings

Our surveyors came to Pasadena for the roses and stayed for the machinery. Within a few miles there is a library with a Gutenberg Bible, a museum full of Degas, a 1908 house built like a piece of furniture, a stadium with a flea market in its car park, and the Jet Propulsion Laboratory, which operates several of our distant cousins on Mars. The robot asked to stay at JPL indefinitely. The request is under review. The city is also next door to Altadena, which lost a great deal to the Eaton Fire in January 2025; we have tried to write about that part plainly and with care.

Robot Enthusiasm Index, by month

March–May is green, mild and in bloom. November–February is the clearest season, with the parade and snow on the mountains some years. July–September is hot (often 95°F+) and is wildfire season — check conditions before any mountain plans.

Items of Interest

a catalogue, with candid notes from the field robots

See
No. 1

The Huntington

Oxford Rd, San Marino (next door)

Library, art museum and some 130 acres of botanical gardens on a railway magnate's old estate. A Gutenberg Bible, Gainsborough's Blue Boy, a Japanese garden, a Chinese garden with a teahouse, and a Desert Garden of cacti that look like they're plotting something.

Closed Tuesdays. Book weekend tickets ahead. The free first-Thursday tickets release on the last Thursday of the previous month at 9 a.m. and vanish in minutes. Do the Desert Garden first, before the heat.

No. 2

Norton Simon Museum

Colorado Blvd at Orange Grove

One of the best small museums in America. Degas dancers, Van Gogh, Rembrandt, Zurbarán, a serious collection of South Asian sculpture, and a sculpture garden built around a lily pond. Its façade appears on television every January 1 as the parade turns the corner.

Closed Tuesday and Wednesday; open until 7 on Friday and Saturday. Free the first Friday of the month, 4–7 p.m. Parking is free, which in Los Angeles County counts as a sight in itself.
Eat & Drink
No. 3

Old Pasadena & Colorado Blvd

Colorado Blvd at Fair Oaks Ave, east to Vroman's

Twenty-odd blocks of restored brick buildings, alleyways and courtyards with restaurants, bars and shops. A mile east along Colorado is Vroman's Bookstore (founded 1894), the oldest and largest independent bookshop in Southern California, beside the Pasadena Playhouse.

Explore the alleys (Mills Place, Miller Alley) rather than the main drag. At dusk, walk west to see the Colorado Street Bridge. Vroman's sold its building in 2025 but has a long lease and is still trading. Check the events calendar.

No. 4

The Gamble House

Westmoreland Pl, off N. Orange Grove

Greene & Greene's 1908 masterpiece of the Arts & Crafts movement: teak, mahogany, stained glass and joinery so fine it looks poured rather than built. Film buffs know it as Doc Brown's house in Back to the Future.

Guided tours only — Tuesdays and Thursday to Sunday. Book ahead; tickets are non-refundable. Photos allowed, no flash. Then walk the surrounding streets: the neighbourhood is a Craftsman catalogue.

No. 5

Rose Bowl & the Flea Market

Arroyo Seco, Rose Bowl Dr

The 1922 stadium in the Arroyo Seco, home of the Rose Bowl Game and, for now, UCLA football (there's an ongoing lawsuit about a move to SoFi). On the second Sunday of every month it hosts the Rose Bowl Flea Market: 2,500+ vendors of vintage clothing, furniture, and things nobody can identify.

Flea market: VIP early entry from 5 a.m., general admission 9–3. Check rgcshows.com for current prices and how to buy tickets, bring cash for vendors, and wear real shoes — it's huge. On other days, walk or run the 3.1-mile loop around the stadium.

No. 6

Rose Parade & Float Decorating

Rosemont Pavilion, Seco St (decorating); Colorado Blvd (parade)

The Tournament of Roses Parade has rolled down Colorado Boulevard on New Year's morning since 1890 (moved to January 2 when the 1st is a Sunday). Every float must be covered in flowers, seeds, bark or other organic material. Watching volunteers glue it all on is arguably better than the parade.

Float decorating viewing at Rosemont Pavilion runs about Dec 28–30 (about $21.50 in 2025; tickets online only). On parade day, grandstand seats sell through Sharp Seating. Or camp on the kerb from noon on Dec 31 — bring a chair, blankets and patience.

No. 7

JPL & Caltech

Oak Grove Dr, north Pasadena / Caltech campus, E. California Blvd

NASA's Jet Propulsion Laboratory built and drives Curiosity and Perseverance on Mars, along with the Voyagers. Free weekday tours visit the von Kármán Visitor Center, the mission control room and the Spacecraft Assembly Facility, where spacecraft get built under glass. Caltech, which runs JPL, has a calm, leafy campus in town that anyone can walk around.

Tours are free but limited. Dates open a month at a time, you must book at least three weeks ahead, there are none on weekends, and adults need a REAL ID or passport. If you can't get one, watch for the Explore JPL open house in October (Oct 10–11 in 2026). Our robot had to be removed from the clean-room window. Twice.

No. 8

Mount Wilson Observatory

Mount Wilson, via Angeles Crest Hwy (SR-2)

Up in the San Gabriels at about 5,700 ft. Edwin Hubble used the 100-inch Hooker telescope here to show that the universe has other galaxies and is expanding. The Eaton Fire came very close in 2025. The grounds are open to visitors again, with weekend tours and occasional public nights at the telescopes.

Grounds open daily 10–5. Weekend public tours and the Cosmic Café run on weekends. Use the observatory's own directions page, not your phone, and check Caltrans for SR-2 closures. It's about an hour up, and cold at the top even when town is warm.
Do
No. 9

Eaton Canyon & Altadena

Altadena Dr, east Pasadena

Eaton Canyon was once the local favourite hike: an easy walk to a waterfall. The Eaton Fire began here on January 7, 2025, and swept through Altadena. It destroyed thousands of homes, took lives, and burned the nature center. The canyon is still under a hard closure; LA County lists its trails as closed into 2027.

Please don't trespass — rangers patrol, fines are steep, and the slopes are unstable. For a hike, try Hahamongna Watershed Park or Chantry Flat in Arcadia (check current Forest Service status). If you want to help, spend money at Altadena businesses that have reopened. That is worth more than a photograph.

No. 10

Day trip: Downtown LA on the A Line

Memorial Park station, Old Pasadena

The Metro A Line (formerly the Gold Line) runs through Pasadena, South Pasadena and Highland Park to Union Station in about 30 minutes, then on through Little Tokyo and downtown. Union Station's Mission-meets-Art-Deco waiting room alone is worth the trip.

Load a TAP card or use the TAP app. From Union Station, walk across to Olvera Street for taquitos, or stay on to Little Tokyo. Avoid driving into downtown — the train is cheaper and cleverer.

Transit Directives

how to get there, by air, road and rail

Fly toBUR

Hollywood Burbank Airport

~25 min via SR-134 / I-210

The easy one. Small, quick and close, with plenty of domestic nonstops. You'll be at the Rose Bowl before LAX passengers have found their shuttle.

Compare rental cars at BUR →
Fly toLAX

Los Angeles International

~45–75 min via I-110 or I-405 (traffic decides)

The big hub, with nonstops to everywhere. Allow 90 minutes at rush hour. The FlyAway bus to Union Station plus the A Line is a car-free option.

Compare rental cars at LAX →
Fly toONT

Ontario International

~40–50 min west on I-210

Easy and uncrowded, east of town. Often cheaper, and the drive in along the foothills is pleasant.

Compare rental cars at ONT →
From downtown LA
Arroyo Seco Parkway (SR-110), the first freeway in the West (1940): narrow, curvy, about 20 minutes. Or the A Line, about 30 minutes from Union Station.
From Burbank / the Valley
SR-134 east to Pasadena, about 20–25 minutes outside rush hour.
Up the mountain
I-210 to La Cañada Flintridge, then Angeles Crest Hwy (SR-2) and Mount Wilson Rd. About an hour to the observatory. Check road status first.
Getting around
Old Pasadena, the Playhouse District and the A Line are walkable or connected. Pasadena Transit buses cover the rest. You'll want a car for JPL, Mount Wilson and the Huntington.

Stay near Old Pasadena or the Playhouse District, take the train into LA, and drive only for the mountains. Avoid the 210 and 110 between 7–9 a.m. and 4–7 p.m. if you value your afternoon.
