Why the Natural History Museum
The Natural History Museum of Los Angeles County (NHM) is the largest natural and cultural history museum in the western United States. It houses over 35 million specimens and artifacts, some dating back 4.5 billion years. The Dinosaur Hall alone — with over 300 real fossils, 20 complete skeletons, and the world's only Tyrannosaurus rex growth series showing a baby, juvenile, and adult T. rex — justifies the visit.
But the museum is more than dinosaurs. The Gem and Mineral Hall has over 2,000 specimens including a vault of diamonds, rubies, and sapphires. The "Becoming Los Angeles" exhibit tells the story of the city from Tongva settlement through Spanish missions to modern metropolis. And the monthly First Fridays event — live music, DJs, cocktails, and nighttime museum access — has been running for 20 years and is one of the best cultural nightlife events in the city.
The Highlights
Dinosaur Hall
The crown jewel. Over 300 real fossils and 20 complete dinosaur skeletons. The centerpiece is the world's only T. rex growth series — three specimens at different life stages displayed side by side. The Dino Lab lets you watch paleontologists working on real fossils behind glass. Dinosaur Encounters shows bring dinosaurs to life with life-size puppets.
Age of Mammals
An epic evolutionary story spanning 65 million years with 240 specimens — mastodon skeletons, whale skeletons, and the complete arc from the extinction of dinosaurs to the rise of mammals.
Gem and Mineral Hall
Over 2,000 individual specimens. The vault section features diamonds, rubies, sapphires, gold, and precious stones on display. The largest meteorite collection on the West Coast is here.
Diorama Hall
Two floors of meticulously crafted animal dioramas depicting habitats from North America and Africa. Immersive scenes with detailed painted backgrounds and realistic staging, maintained and updated over decades.
Becoming Los Angeles
The museum's permanent exhibition on LA history — from indigenous Tongva life through Spanish colonization, the rancho era, the movie industry, and the modern city. Genuinely well done and specific to LA in a way no other museum achieves.
Unearthed: Raw Beauty (through April 27, 2025)
Current special exhibition featuring rare minerals and crystals, some never before displayed publicly. Dazzling and photogenic.
Nature Gardens & Butterfly Pavilion
3.5 acres of outdoor gardens showcasing urban LA biodiversity. The Butterfly Pavilion (spring/summer) is a walk-through experience with 30+ live butterfly species. The Spider Pavilion opens in fall.
First Fridays
The museum's monthly First Fridays event (typically the first Friday of each month, 5:30–9 pm) transforms the museum into a nightlife venue. Live music, DJs, cocktails at pop-up bars, a featured science discussion, and access to the galleries at night. Now in its 20th year — this is one of the most consistently excellent cultural events in LA and a legitimately great group outing.
