Step Back in Time
Mark your calendar—September 26, 27, and 28—because Los Alamos is throwing a party you won’t want to miss! For three full days, our charming town comes alive with music, laughter, and plenty of small-town fun.
Stroll through artisan booths filled with handcrafted treasures. Cruise the classic car show and admire shiny rides that bring back memories of the good old days. Savor delicious bites and refreshing drinks from local food and beverage vendors.
Feeling lucky? Try your hand at the famous Cow Pie Bingo! Cheer on contestants at the Buck Contest or kick up your heels with live music that will have you dancing in the street. Hungry for more? Don’t miss the Old Days Dinner—an annual tradition that brings friends and families together around the table.
Get moving with the spirited 5K Run, then grab a good spot for Sunday’s grand parade. Floats, horses, bands, and community pride all roll through downtown in a colorful finale you’ll remember all year.
Los Alamos Old Days isn’t just an event—it’s a celebration of history, heritage, and heart. For decades, visitors from across California have gathered here on the last full weekend of September to share in the magic. This year, we invite YOU to be part of the story.
Three days. Endless memories. All happening right here in Los Alamos.
