September Holidays

One of the big September Holidays, is Labor Day, which is on the 1st Monday in September each year. It is typically, the last mini-vacation of the summer season, before the kids go back to school.  For those living in the United States, in California, or Nevada, lots of folks flock to Lake Tahoe for the Labor Day weekend.

Pictured above is Divers Cove in the Sand Harbor State Park on the Nevada side of the Lake. For more info, please check out my Sand Harbor State Park page, on my Truckee Travel Guide website.

Below you will find our listing of September Holidays and Observances, that fall in the month of September.
