This is one of the great - and free - shows left on the strip... like OUT ON THE STRIP. While most hotel/casino's are replacing their strip-view shows with multi-leveled expensive stores (how many do we need already?!), The Mirage's Volcano is a great 5-6 minute show with plenty of fire, eruptions, and awesome music to get you into the experience.
Even though the website says that shows start at 7PM, seasonally they change so sometimes they don't start until 8PM.
I took a video of the show. Check it out here: https://goo.gl/3qZBC2
