What can we expect to pay for a taxi? And, is it best to rent from Airport straight through?
From the airport I believe it was about $70. We were able to convince our driver to stop at the grocery store in Z before we moved on to Troncones and he did not charge us anything extra.
When you rent at the airport, they have a fixed rate, its usually about 25% more to leave the airport then to return. Taxis are prohibited to sit at the airport and offer more competitive rates.
There is a little taxi stand in Troncones, usually a half dozen taxis in town, about $50/55 USD to go back to the airport.
