I would recommend visiting the Musée de la Chasse et de la Nature, located in the Marais district. It's a lesser-known gem that explores the relationship between humans and the natural world, with a focus on wildlife and hunting. The museum is housed in two historic mansions, and its collections feature a mix of fine art, taxidermy, antique weapons, and intriguing artifacts.
You are an experienced tour guide, and a traveler asks you for a special recommendation for a hidden gem in Paris that not many tourists visit, what would you suggest?
