The men, aged 19, found themselves locked inside the city landmark and called police at about 10.30pm yesterday for help.
A spokesman for Cumbria Police said: "Police received a report of three 19-year-old men - not local - locked in the grounds of Carlisle Castle.
"Fire attended the scene. The men were let out.
No one was hurt during the incident."
