A large stretch of river that runs close to the Boulderclan borders. It contains small fisht that the Boulderclan cats eat for fresh-kill, as well as some plants that are used by the medicine cats of the clan. Most of the clan's water comes from the river, and it is also a good place to train apprentices, using the stepping stones that break the surface of the water.

A large expanse of grassy field that lies just outside the Boulderclan camp, the Aurora Clearing is known for the bright lights that sometimes occur over it at night. Cats love to go there and stargaze with another that they might be...interested in. It also contains two or three flat-topped boulders that cats like to sit as they look up at the skies.

A ledge that is extremely rocky, and it easily landslides and shifts. Cats exercise much caution around this area, as it is also inhabited by snakes and large birds of prey. There is less grass here, but a lot of rocky cover to hunt in. It is also hotter in this area, as there is little to no trees shading the rocks, so cats need to be wary of dehydrating/fainting.

In the northernmost point of BoulderClan is where the Northern Pine Forest is located. The forest is fairly large and consists of mainly pine trees. To get there, BoulderClan cats must pass through the mountain range that cuts through their territory. Often, large hunting parties are sent here, since the forest is heavily populated with prey. However, it takes a whole day to get there and back to BoulderClan camp, so the hunting parties often take shelter in the pine trees over night and return the next morning.
