Wow, Margo, it's been SOOO long since I ran those mazes. I remember there was a trick to it -- if you can see the little branches in the wall right in front of the entrance, but I forget if they meant go right or go left (I think right, but...) I know someone had drawn maps. Fangs?
Edit: found a hint from way back - it IS from Fangs:
For the F3 and the M6, follow this:
When you are going up to the maze, you will see 1 of 4 possible bushes.
First, bushes without any branches showing. For this one you only have 2 options, left or right. For this one, go right and follow where it takes you until you have an opening on the right. This will have you going right, left, left, right. Do NOT go into the center of the maze at all.
Second, if you only have 2 options (left or right) and there are branches visible in the bush, then go left and follow it around until you can take another left.
Last two are simple. You'll either be forced to take a right OR you'll have 4 options (2 left and 2 right). If it's the last one, take the last right. Then for both, you turn left, left again, take last right (if there is more than 1), right again then left.
It sounds harder than it really is.
