I've got a task to kill trolls for a slayer task, but even with the map can't seem to get to the troll cave that is west of Rellekka. Do I have to do a quest to get access to that area or am I just missing what the best root is?

There should be a route east of that magic tree that is east of Rellaka (with all the bunnies around it).

 

 

 

You can go in through Burthorpe, too, but be careful of flying boulders!

Umm, the one you're talking about is on your way to Keldagrim, I think. Go that direction and instead of continuing through the mountain, make a right down the larger passage. There are a moderate amount of trolls there.

You can also do this task it in or just outside of the Troll Stronghold, or on the Death Plateau.

Thanks everyone.
