Expand to see the parent tip
The Merry Memories parade sends glowing floats, bands and dancers down Main Street, with Santa Claus riding as the one and only Santa in the lineup.
Before or after, walk over to Roosevelt Park, where the Longmont Lights display twinkles nightly from late November into early January.
Parent tip: Check the city’s posted parade route before you go, since construction has shifted it, and leave the candy bags at home because nothing is thrown from floats.

A story for the drive home
A morning with Santa or an evening of holiday stories tends to end the same way: tired kids, a long drive and one more book before bed. Our picture book follows Rally the corgi on his first train ride to see his grand-paw-rents, and every page is painted by hand. If your family is spending December missing someone, it was written for that too. For the car, print our free corgi and train coloring pages.
A bedtime story after seeing SantaRally Takes the Train is a five-minute rhyming picture book about a corgi’s first ride on a California train, hand-painted in watercolor. $16.99 on Amazon, ages 0 to 8.
