K2: Broad Peak is an expansion for the mountain-climbing game K2 that includes a double-sided game board, tokens and new rules. The game board features the twelfth-highest mountain in the world, formerly known as ''K3'' and now typically called ''Broad Peak'' due to the length of its summit.

Broad Peak gives you two very different challenges to undertake, which are based on the historical achievements of Polish mountaineers on Broad Peak in 1984. Both challenges have their own game boards and rule changes to make them individual game experiences.
The first challenge is ''Race to the Top'', a quick and thrilling game in which the game lasts three fewer days than normal, players have no tents, and the deck contains fewer acclimatization cards. Also, the board just has fewer places to climb, so watch your step!

The second challenge is ''Traverse of Broad Peaks'', which is more strategic and a little longer then the base game. The board shows three tops of Broad Peak and mountaineers can earn additional victory points for traversing all of the mountain and for reaching the top of each of the three peaks - which is very difficult to do, especially since the mountaineers have only one tent with them.
