Im doing a clue scroll and I need to acsess the camp, how? Theres a boulder in the way and it sais its too heavy to even try.

Have you completed the mountain daughter quest?

 

If not follow the first section of the quest guide as it covers entering via over means.

Use rope -> boulder

There's is a path above the guard.At the end of the path there is a boulder. Use a rope on it and you should descend into the camp(there's even a small Lord of the Rings portion put in that animation " the rope unties itself from the rock...").
