the hill giants in the wild are popular for pking. You will not be alone very often so it'd be tough. bone yard has regular bones too so it would probably faster to pick up big bones and regular bones as you go if you are planning on using regular To get to crandor you have to have done at least part of Dragon Slayer up to the cave while finding the door. If you've found the door you can go through the volcano on karamja from port sarim (south of falador, west of draynor) then through the hidden door/wall and through there and up the ladder and around to the moss giants. buying is probably fastest but definately not as cool. Bone yard is probably next fastest but boring. Chaos is probably next but still boring. Dungeon hills are decent but crowded crandor mossies are good but a little high level for you and are far from a bank if you need to bank things. varrock moss are far too.
