The holiday season has officially arrived with Thanksgiving kicking off the season on Thursday. With the federal holiday comes a collection of closures and events throughout the state.

Most government offices and city agencies in the state will shutdown on Thursday in observation of Thanksgiving and the day after, creating for a long weekend. All courts will be closed, and cities and counties will shut down government buildings and offices to celebrate the two days. Be sure to check websites of any business or government entity before traveling there Thursday or Friday.

There will be no mail services on Thursday, either, but will return on Friday. Most businesses will also be closed on Thursday, though some may be operating with a limited schedule. 

Denver, Douglas, Adams, Arapahoe and Jefferson counties will all be celebrating the holiday on Thursday and Friday, closing all government offices. These closures will include services like the Department of Motor Vehicles and libraries.

All 24-hour agencies — like emergency services and the Denver International Airport — will remain fully operational on both days.

Street parking throughout the city of Denver and Boulder will be free on Thursday for the holiday. It will return to normal prices on Friday. Denver public transportation via the Regional Transportation District will also be operating on its holiday schedule.

All state parks, county parks, campgrounds and boat ramps will remain open through the holiday. Colorado Parks and Wildlife is offering free entry to all state parks on Friday for Fresh Air Friday.
