“An open trail through the monument's southern wilderness.”— QuinTCM TCM
Initially, the trail follows the same path as the Mammoth Crater Trail. However, before reaching Mammoth Crater, the trail turns south and moves along the crater's rim. The trail then begins turning north along the crater's rim where it reaches a fork, which is the point at which the loop for Big Nasty Trail begins and ends. Either continue north along the loop or turn west along the loop. Either way the trail returns to this point. After completing the loop, continue back along the rim of the crater to the trailhead.
The trail is open and exposed like nearly all of the trails in the monument. Nevertheless, as the trail skirts the southern boundary of the monument, it nears Modoc National Forest. Thus, giant Ponderosa Pines sporadically dot much of the trail. The trail is named for a brush covered lava flow to the north of the loop. Someone, somewhere, at some time, someone said: "it is big, and it is nasty!"
