The newlyweds, who tied the knot on New Year's Eve, enjoyed a magical trip to the theme park resort in California on Saturday (15 February).
Kaley took the lead and showed 26-year-old Ryan around as it was his first ever visit to Disneyland.
Posing happily with her man, 28-year-old Kaley said: "Mini honeymoon at the happiest place on earth! @ryansweething #myhusbandisadisneyvirgin!"
In another photo, the lovebirds pose with Mickey Mouse in the magical kingdom. Captioning the snap, Ryan said: "First time meeting the man himself!! @normancook #magical."
The day before their trip to Disneyland, the couple celebrated their first Valentine's Day together and Ryan's romantic gestures left Kaley impressed.
She wrote on Instagram: "Thank you @ryansweething for the most perfect valentines ever." Aww!
Kaley and Ryan met in the summer of last year and enjoyed a whirlwind romance, getting engaged after three months of dating.
Big Bang Theory star Kaley then exchanged vows with tennis pro Ryan in a romantic ceremony in Southern California on 31 December 2013.
Shortly after celebrating their big day, Ryan proved his love and commitment by getting a tattoo of Kaley's name on his forearm.
