Are you referring to Signal Peak? If so a few (3) hours. When we went we went to the top and then came back down the same way. Going down towards the Cisco Grove side from what I understand is basically a dirt road that utility companies use to service the towers etc. up there. Of course time is dependant on how many people in the group, how well their rigs are equipped, and if they want to try every diffcult obstacle or go around. I went with a group and was wondering what was taking so long. Finally got my fat butt out of the jeep walked up and saw the spotter taking everyone over the large rock, some people wanted to try, but had a hard time (independant suspension) when they could have simply went around.
