If you can sneak in a Colorado ski vacation before the new year, don’t miss a stopover in Denver, decked out with downright dazzling light displays during their “Mile High Holiday” events. December 2 and 3 see the “9NEWS Parade of Lights” march from the festively illuminated City and County Building (the city’s largest lighting display, it’s lit November 25) through the downtown Denver area, featuring nearly a million shiny lights, a dozen twinkling floats, soaring balloons, marching bands, and more (free; www.denverparadeoflights.com). Also pop by the Denver Botanic Gardens’ “Blossoms of Lights” exhibition, where more than a million colorful holiday lights are integrated into the gardens, and further enhanced by extras like glistening ice sculptures and a strolling choir (December 2–January 1; $9.50 adults, $6.50 kids ages 3 to 12; www.botanicgardens.org). Meanwhile, the Denver Zoo’s “Zoo Lights” event invites visitors to embark on a holiday lights safari – its 38 acres are embellished with more than 150 animated animal sculptures (December 9–January 1; $9 adults, $5 kids ages 3 to 11; www.denverzoo.org)
