"The airy central conservatory, which opens up right as you enter Bellagio, was inspired by the verdigris framework of Art Nouveau conservatories of Paris. Even though Las Vegas sits smack in the middle of the Mojave Desert, you can see the changing seasons in all their glory here as the garden transforms five times per year with fresh flowers; towering animatronic butterflies and birds; burbling fountains and bobbing lanterns. Each of its seasonal “theatrical presentations” of the elements is totally new. You'll never see the same things twice. And each is more transporting than the last. It's free, requires no effort to navigate (unless you're trying to elbow your way through all the smartphone-wielding selfie-takers). Locals love it as much as tourists, and it's one of the top free attractions in the city." - Andrea Bennett
