Depending on the taxi company you choose, the type of vehicle involved, or the distance involved whether a one-way or return journey, the pricing may vary outright. My Son is located in Quang Nam Province, which is quite far from Hanoi-an approximate distance of 700 to 800 kilometers. For the long distance, a taxi may not be appropriate or economical. Instead, it is very common for passengers to take scheduled flights, trains, or buses between Hanoi and My Son.
In a rough estimate, a one-way excursion could cost anywhere within this context between $200 and even $400 and probably more. This is just a raw cut, so find taxis by way of local taxi firms or perhaps a ride-hailing app like Grab for further information as to pricing. However, for a more budget-friendly and comfortable traversing, some prefer flying to Da Nang and then getting taxis or shuttle buses to My Son some 70 kilometers away.
