Go to the Jardins De Lumiere close to 9PM, when the crowds have thinned significantly. I was there at 7PM, and the Jardin Chinoise was at capacity. \n\nBesides this minor complaint, it was a very surreal experience. The cold air, the almost surreal placement of the displays (whether it's butterflies, pagodas, or people) and the way it's almost encouraged that you take your time going through each lighted piece.\n\nThe Jardin Japonais is equally beautiful, albeit in its own way. There's none of the exhibition pieces--instead the whole garden is a dazzling spectacle of lights in different colors and intensities.\n\nAllow yourself plenty of time to appreciate the two gardens. It's a wonderful experience.
