How do I best access the serpentine belt on a 2010 Honda CRV?

I was going to dive in and change the belt on my father s Honda CRV, I opened the hood, and it is so tight, that even in daytime i must use a flashlight to look "top->down" to view the belt and even then, I cant see all of the belt or all of the pulleys.

I suspect some parts may be better accessible from underneath the car, or by removing the inner wheel well.

Without resorting to trial and error and wasting hours of time, is there any process or technique that will make changing the belt easier and less frustrating than it appears it will be?
