Take the lower level path that comes in from the north. Run past the wolves, they'll de-aggro faster than you'd think. WALK past the trees. And whatever you do, stand perfectly still and OUT OF THE WAY of any passing frogs, they will aggro you if they collide with you.

There will be two crows guarding the box. They aggro sight, either kill them or wait til their backs are turned.

Remember, patience.
