I've searched google and none of these methods have helped. How do I get to catherby? Sorry I'm an idiot.

traverse the white wolf mountain aaaaaaaaaaaaaaaaaaaaaaaaaaa

Use the edgeville lever to teleport into wildy, then use the lever again to be teleported to ardougne. Then you run northeast until you reach the beautiful beach of catherby

GE -> camelot teleport -> use it -> southeast 15 secs

go over big mountain with scary wolves bring lots of food so u dont die it's VERY scary up there also don't fall down!!!

The same way you do in old school untill you unlock the home tele over there then use that

If this is like OSRS, this is very fast yes.

This is safest way for new accounts. Otherwise from Taverly go to through white wolf mountain, you have to go through a cave entrance, run down and through another cave entrance.
