Blossoms of Light and Trail of Lights
November 29 to January 1
If you're looking for high-tech, the Denver Botanic Gardens has you covered. Its Blossoms of Light display, which includes more than a million lights, is synchronized in time to holiday music. What's more, you can purchase 3D "Holospex", which transform the lights into prismatic holiday shapes before your eyes. For those who are more into Christmas Past than Christmas Future, there's the Trail of Lights, which features the garden's on-site, 1880s homestead decorated for the holidays with a vintage Christmas theme.
