The 2016 Christmas event is an event consisting of many different activities. It was released on 1 December 2016 with the Christmas Advent Calendar and reindeer-terrorbird racing.

The Christmas Quest Episodes called Frostworld is a four-part holiday quest that revisits previous Christmas events, starting with the 2007 Christmas event. The first three episodes of the quest, entitled "A Blast the Past", were released on 5 December; the fourth episode, "Christmas Never Dies", will be released on 19 December, adding some more repeatable skilling activities.

The Winter Weekends and Sliske's Christmas Adventure are also a part of the event.

The snow for the course of reindeer-terrorbird racing was released as a hidden update before the start of the event on 28 November 2016.

Although portions of the event take place in the Land of Snow, the ice amulet does not recognise this and thus players are unable to summon their snow imp there. However your snow imp can be summoned at the banquet dinner in the Towering Feast's area. It will just follow you to Santa's neighbourhood if you leave the banquet area afterwards but you will be unable to talk to him.

Sinterklaas, next to the A Towering Feast cupboard, is a reference to the Dutch and Belgian version of Santa.

The snowballs you can collect in A Towering Feast, unlike snowballs previous years, can be stacked with the original snowballs the 2011 event when you put them in the bank.

Various bosses received cosmetic Santa Hats and other decorations like the previous two years on 19 December 2016.

Goebies, both on Mazcab and near the heart of Gielinor, received cosmetic Santa Hats.
