Biking from La Ropa

I have a friend that will be staying on La Ropa - specifically, I don't know the property location where they are staying. My friend is thinking of bring his road bike(bicycle) along to cruise with me - I stay in Ixtapa.

How could I instruct my friend in terms of how hazardous, likleyhood, and or easiness of getting from La Ropa to the bike path at the Zihua entrance to Ixtapa then proceeding to meet me in Ixtapa...

Not looking for directions, but, rather a qualitative understanding of the possible route's challenges....

Thank-you
