Colorado is loaded with cool tourist attractions that are worth a visit at any time of year. Luckily, some of the best activities offer free admission during select days and times throughout the year.
We’ve rounded up the free admission days listed by attraction previously, so based on feedback, we’ve also provided a list of free days in chronological order. From national and state parks to museums and zoos, these are some of the best attractions laid out from January to December.
Dates and times are subject to change. Check ahead to confirm the free day is happening, its time, and any special requirements. Some spots, such as the Denver Zoo, require you to register for your free day online to get a ticket, while walk-in tickets for free days are not available at the Denver Zoo.
