Celebrating their son Mason's 3rd birthday, Kourtney Kardashian and Scott Disick headed out to the Gold Coast Railroad Museum today (December 14).

The E! reality television stars hopped on a train ride and looked to be having a marvelous time together as a family at the Miami, Florida theme park.

Earlier today, Kourtney took to her website to share her joy- "Happy Birthday to my most precious angel who has forever changed my heart.”

She continued, "I will never forget the day you entered my life, three years ago. It is an honor and a joy to watch you grow every day."

Tonight, Miss Kardashian has some big plans as well- "I got a cute cake and everyone got him little presents, so we'll just do something fun like that."
