The 51st annual Trail of Lights will open to the public starting Dec. 8 and will run through Dec. 22. The walkable trail is one of the three most-attended events in Austin after the Austin City Limits Music Festival and South by Southwest Music and Media Conference, with more than 400,000 guests attending the holiday spectacle each year. Special transit routes are available for those who do not wish to drive their vehicle to the event. [g-slider gid="120364" width="100%" height="55%"]
