Fort Collins is located an hour and six minutes away from Denver International Airport. We do suggest renting a car to get there as that may be the easiest route (try looking into Costco travel if you have a Costco card). If you do not want to rent a car there is a bus service you can rent and it costs $40-$50 each way. We've attached the link below if you are interested.

Fort Collins is a small town, it has many nice hotels. We've attached a couple hotels below that are super cute and close to the heart of Fort Collins. There are many airbnbs located around town as well, if you have a big group of people coming we highly suggest doing this :)
