The streets were packed once again in Islip for the annual Santa Parade down Main Street.

The Islip Chamber of Commerce organizes the parade each year.

The march culminates with an appearance from Santa atop an Islip firetruck, then a tree-lighting ceremony outside Town Hall.

There, holiday revelers were also treated Saturday night to caroling from the cast of Islip High School’s The Little Mermaid, and awards were handed out.

Dance Connection won the best-lit float. Exchange Ambulance of the Islips won the best-lit float award from among first responders.
