Hole 4 throws from the top of the hill down around the tree line to the basket to the left of the big pine tree at the bottom of the hill.

Avoid the trees to the left, finding your disc is a pain in that mess and more times than not it ends up getting hung up in limbs which makes it really difficult to find.

The bonus hole for this one is a big one, you throw over the trees to the basket for hole 5. It's a dangerous hole as the risk of losing your disc is significant.
