With the holiday season in full swing, December is full of exciting and festive events — from Christmas in the Park and a Santa-bedecked fun run to a fantastical light exhibit and holiday sing-along concert. These are the best things to do in the South Bay this December.

Tuesdays-Sundays through January 6
San Mateo
1651 Coyote Point Drive
Inspired by the science of light, this annual exhibit at CuriOdyssey in San Mateo is a glowing forest of science — a maze of luminous botanical geometry, rainbow refractions and swirling projections. Explore the physical properties of light, such as photoluminescence, color, additive light mixing, waves, fluorescence, fluid dynamics, subtractive color mixing and refraction.

Through January 1
San Jose
Plaza de Cesar Chavez, 194 South Market Street
Each year the Plaza de Cesar Chavez in downtown San Jose is transformed into a holiday fantasyland with over 40 musical and animated exhibits, glittering lights and a 50-foot Community Giving Tree. Guests can enjoy a winter wonderland of lights, songs and local entertainment while strolling through an enchanted forest of trees decorated by San José schools, community groups and businesses.

December 6 and 7
San Jose
California Theatre, 345 South 1st Street
Symphony San Jose is teaming up with the Symphony San Jose Chorale, the Cantabile Youth Singers, New Ballet and others to journey through a selection of favorite carols and holiday music. The concert will include “Sleigh Ride,” selections from The San Jose Nutcracker, Alan Silvestri’s Polar Express Suite, “The 12 Days of Silicon Valley” and the always-popular audience sing-a-long. Those with young ones can arrive early for the chance to meet Santa Claus and decorate their own gingerbread cookie.

December 13-23
San Jose
California Theatre, 345 South First Street
New Ballet’s The San Jose Nutcracker at California Theatre is a holiday tradition for the South Bay. But this isn’t your average Nutcracker. Set in San Jose in 1905, The San Jose Nutcracker incorporates local history and landmarks to put a unique spin on a familiar story. And, for the first time in 10 years, Symphony San Jose will accompany all performances. San Jose Parents with toddlers and young children can also enjoy, as the New Ballet Company includes a special, shortened version of the show called “My Very First Nutcracker” on December 15 and 22.

December 14
San Jose
West Santa Clara Street and Almaden Avenue
Get your run on at the 2023 Silicon Valley Santa Run in downtown San Jose. Not only are runners encouraged to dress in their favorite holiday character or tradition such as Santa, Mrs. Claus, the Grinch, reindeer, elves, dreidels, menorahs, ornaments or more, there’s post-race milk and cookies at Christmas in the Park and a short fun run just for the kids. All event proceeds go to local charities supporting a safe, clean, and vibrant San Jose.
