The Gilder center just opened and has made visiting this museum a lot easier and more fun. Plus, the online ticketing is a gift: if you’re a tri-state resident you can now, finally, enter your zip and do the “pay what you wish part” on the app instead of the previous clunker: get your timed admission but still have to wait inside in line to pay. Visitor? Ok, you’ll pay more for basic admission and a few bucks more for the butterfly exhibit, which you will enjoy, with or without kids. With kids, it’s a must must must see. Whatever, do it all on the museum app, get in quick (early in day is good, but even a recent crowded weekend was fun). Entering through the Columbus Ave Gilder entrance is fun, less people, has a sweet little park winding in front w benches—you can cobble together lunch from food trucks or even a cool green market if it’s there (Sundays, maybe other days as well). Gilder is a huge sculptural addition that makes access to the Gem and Mineral room easy (and it’s dazzling, definitely go right in). There are many fun, family friendly exhibits in the Glider center itself, from the aforementioned butterflies on the 2nd floor (timed admissions), to ant watching on the first floor and much more. I suggest you focus on Gilder/Gems and then scoot up to 4th floor DINOSAURS, the gems of the museum. Everyone loves the naked, hairy little Neanderthals, but like a lot of the old museum, they look taxidermied (it was, after all, Teddy Roosevelt and his shoot ‘em up peers shootin’ ‘em up and bringing ‘em back to end up in dusty dioramas. And Teddy….that’s a whole nother story, as they say, but one can appreciate that he and his family started this wonderful museum and it’s a true treasure).
