Spiral Mountain is a small, serene valley located within the vicinity of the Isle O' Hags, it is home to Banjo, Kazooie and Tooty and has appeared in every game in the Banjo-Kazooie series. The valley is named for the small, spiraling mountain, surrounded by water, located in the center of the valley.
Besides the mountain Spiral Mountain is named for; the location also contains Banjo's house (which was destroyed at the beginning of Banjo-Tooie), a large waterfall that feeds into a small lake.
Most of the land is grassy, and the valley is relatively small. Much of the land seems to be taken care of by Banjo, as there is a garden area inhabited by Toppers and Bawls. In Banjo-Tooie much of Spiral Mountain was destroyed by Gruntilda Winkybunion, leaving ruins behind and breaking the rope bridge that connected the valley with her lair.
Many items are hidden throughout Spiral Mountain. These include:
