She began her campaign in a maiden race over one mile at Newbury Racecourse on 18 April and recorded her first success as she won "comfortably" by one and three quarter lengths from the favourite Derab after taking the lead two furlongs from the finish.

After fighting against Levey's attempts to restrain her she made no progress in the closing stages and came home third behind Premio Bacio and Creative Flair, beaten five lengths by the winner.

[8] Despite her defeat Snow Lantern was moved up to the highest level to contest the Group 1 Coronation Stakes on heavy ground at Royal Ascot and started a 14/1 outsider in an eleven-runner field.

[9] On 9 July Snow Lantern faced older fillies and mares in the Group 1 Falmouth Stakes over one mile on good to firm ground at Newmarket Racecourse and started the 6/1 third favourite behind Alcohol Free and Mother Earth.

[10] Snow Lantern settled behind the leaders along the far-side rail as Alcohol Free set the pace, but was switched right to deliver her challenge in the final furlong.
