by Boulder, Colorado — Halloween 2026 is bringing costume celebrations, family-friendly entertainment and spooky experiences to Boulder as residents prepare for the final weekend of October. Located at the foothills of the Rocky Mountains, Boulder offers a mix of downtown trick-or-treating, Halloween performances, historic ghost tours and seasonal activities for visitors of different ages.
With Halloween falling on Saturday, October 31, families and visitors can plan a full day of festivities, from afternoon activities for children to evening entertainment for adults.
1. Munchkin Masquerade on Pearl Street
One of Boulder’s best-known Halloween traditions, Munchkin Masquerade, returns to downtown on Saturday, October 31, from 3 p.m. to 6 p.m.
Children ages 12 and under can dress up as superheroes, witches, dinosaurs, fairies and other favorite characters before heading along Pearl Street to collect treats from participating businesses.
The event is free and offers a convenient way for families to celebrate Halloween together. Parents can enjoy the costumes and festive downtown atmosphere while children visit participating treat stops throughout the district.
Families should allow enough time to explore the area and check for updates about participating businesses before arriving.
2. Halloween Spooktacular with the Symphony
Families looking for a musical Halloween activity can attend Halloween Spooktacular with the Symphony on October 31 from 2 p.m. to 3 p.m.
This interactive Curiosity Concert features a string quartet and piano in a welcoming setting designed especially for children and families. Guests are encouraged to wear their Halloween costumes and enjoy a performance that combines music with the spirit of the holiday.
The concert provides an alternative to traditional trick-or-treating and can be a good choice for families with younger children who prefer an indoor activity during the afternoon.

The class is scheduled for Friday, October 30, from 11 a.m. to 3 p.m. Participants can explore glasswork techniques while creating a seasonal piece inspired by Halloween.
This activity offers something different from costume parties and haunted attractions. It may appeal to people who enjoy hands-on crafts and want to spend part of Halloween weekend learning a creative skill.
