The Snow Fort, also referred to as the Ice Castle, is a members-only seasonal land den originally released in December 2012. It is available during the winter months for 5,000 Gems. It returned to Jamaa on January 9, 2013 and left in the spring. It returned again on December 18, 2014 then left again in the spring of the following year. It later returned again on January 4th, 2017.
The Snow Fort den is a big ice fort. There is a frozen river next to the structure. There are two levels and a staircase connecting both levels. Outside, there rests several piles of snowballs. In the top-right corner, there is an ice blower (similar to the mud in Appondale) that gives animals an arctic-blue ice tint when they stand in it. The Snow Fort Den wallpapers and flooring are ice-themed.
It has the same basic build as the New Years Party 2013 den, with a few turrets added and flipped around the X-axis.
