Draynor
willow yew cutter, DTM for banking, radial / atpa / filtercolorspie for walking, atpa for finding tree to cut / present, plus start anywhere
EDIT: Requires a lot of neat little reference point for navigation, if you can make this you are pretty much set for walking.
Anything harder than that would just be logic practice but as for knowing how to use SRL, this should cover pretty much everything.
If you want something a harder, mage arena enchanter

Great practice of finding location without reliable color and finding multiple object with different shape.
* Obviously without using SPS*
