- Eastern shore of Lumbridge Swamp - Western shore of Al Kharid (usable both ways).
- Catherby beach, adjacent to Water Obelisk Island (usable only from the obelisk side to the Catherby side).
- South of Karamja Volcano (usable both ways).
- If you try to grapple the strong tree in Catherby a message pops up saying "You cannot see a good spot to grapple the rock" even though you are trying to grapple the tree.
- Unlike other trees, strong trees may not be cut. Strangely, some of the strong trees are smaller than their cuttable counterparts.
