San Antonio’s River Walk is always a hotbed of activity, but the holidays take it to new heights, particularly so in 2011, with the infusion of 20 times more Christmas lights (thanks to the city’s move to more energy-efficient LED lighting). You’ll find the bulk of the 1.8 million holiday lights garnishing nearly 200 trees (done up with 10,000 bulbs apiece) and on 20 holiday-hued bridges, all brightened up even further by carolers bellowing their tunes nightly from passing river barges (singers perform November 26– December 18). The festivities kick off on November 25 (and run through January 1), when the switch is flipped and the “Ford Holiday River Parade,” complete with an entourage of lit-up festooned floats, unfolds.

The quarter is also home to the luminous “Fiesta de las Luminarias” on select weekends (December 2–18), whereby some 6,000 luminarias (candle-lit paper lanterns) symbolically light the way for the Holy Family. Come by after December 3, and you’ll also get to ogle the “River of Lights” spectacle, featuring over 100 underwater lights and fiber optic-outfitted water features along the new Museum Reach section of the River Walk (free; www.thesanantonioriverwalk.com). In conjunction with the amped-up display, the city is additionally holding its inaugural “Light Up Downtown Holiday Contest” in 2011, which has downtown business owners competing for the most creative holiday light displays – and your starry-eyed attention.
