Bear Den is a 5.71-mile road on the east side of Bear Den Mountain in the Lost Gulch area north of Galena. It offers scenic views of the surrounding Black Hills and the Black Hills National Forest. Bear Den branches off Lost Gulch and ultimately meets back up with Lost Gulch in a junction just south of Bear Den Mountain.
Bear Den is predominately rough dirt and small loose rocks, however there is one area containing large, deep ruts. Good tire placement would keep you on top of them, but the risk of slipping down may make going through the center the wiser choice. An illegal bypass route was present, but please stay on the designated trail and do not avoid mud holes or ruts. This would be an easy route if it weren't for this section. High clearance is recommended to make it through the ruts until they are repaired. The ruts can be bypassed by taking Bear Den 1E.
There is little to offer for camping along Bear Den. There is one small pull out south of the intersection with Camp 5, 8044, but it is only large enough for one vehicle.
