New Belgium Brewery Tours (Tuesday - Saturday)
The New Belgium Brewery in Fort Collins has had to greatly modify their previously awesome tour and beer sampling system. They never said why they changed, but it was obvious what the problem was when I visited. Because of the free beer samples, the place was overrun with college kids who wanted to party hard for free.
Now to get a small free sample you must take the full brewery tour, and reservations fill up online weeks or months in advance. If you go there without being signed up for a tour, you can still buy beer at the bar for a discounted rate.
Despite the changes, this is still an excellent small brewery to see and learn about.
Location: 500 Linden Street in old town Fort Collins.
