---The red arrows point to which direction you should go, and the instructions also give pointers on getting to Underleaf. Have fun :) ---
1)--Start off at the fountain in Binxonia, and then head north and keep following the path.
2)--Keep going following the wide path. This little path that goes west leads to a guild house.
3)--Take the west path, continue follow the path. The north path leads to the gold mine.
4)--Well, now the path has been cut off. Don't worry, just use the left mountainside as your guide, and keep on following it.
5)--This cave is the goldmine, but there are many Hillgiant Shawmans inside. Keep follow the mountainside, and be careful of the Hill Giants here if you are a low level.
6)--You're very close to UL now. This cave houses many dangerous creatures, and is home to an iron mine, a silver mine, and a titanium mine. Now, just go a bit south...
7)--You're there! Read the sign, and continue along this little path to the underground town of Underleaf.
