About this Nat Geo Nights

Every third Thursday of the month, join us for special monthly happy hours with stories from National Geographic Explorers, fun interactive activities, lively music, food, and drink specials at our cash bar. Your ticket includes free admission to the National Geographic Museum.

Meet the daring and innovative National Geographic Explorers—conservation technologist Topher White, conservation biologist Juliana Machado Ferreira, and big cat biologist Alexander Braczkowski—who are going to extraordinary lengths to protect the planet. Find out how they’re using cell phones to conserve the rain forest, working to end rare-animal trafficking, and saving critical big cat species from poaching.
