One of my favorite free activities in Las Vegas is the famous Bellagio Fountains. Starting mid afternoon and going into the night, the fountains are choreographed to various songs. During the day I recommend viewing from the front of the lake, looking onto the hotel. But at night, nothing beats a sideview looking onto the faux Eiffel Tower at the Paris Hotel. View from the Front during the Day Check here for the latest selection of songs and the timing of the fountains.
