Taxi to Troncones

We will be in Zihua in October & plan to go to Troncones. If we opt to take a taxi (rather than a bus/combi), what is the approximate fare? Thank you.

There is no official set rate for Troncones, but depending on your starting point, the rate chart on this webpage should be able to help you calculate it.
