A short taxi ride of approximately half an hour from Da Nang will get you here. If you stay at a Hua Hin luxury hotel such as the centrally located Anantara Hua Hin Resort & Spa you will be able to reach the Marble Mountains with great ease. You can have a taxi arranged from your hotel or even hail one from the street.
If you like to travel like the locals using public transport, you can get into a bus travelling from Hoi An to Da Nang. The journey will take only about 20 minutes. Once you hop off the bus, a short walk from the main road will bring you to the entrance of the Marble Mountains.
