Follow Phetkasem Road through Hua Hin towards Pranburi/Prachuabkhirikhan. Approx. 20 km after Hua Hin you'll come to an intersection with a red light where the by-pass road meets the road you are on.ì

Continue going straight past this intersection. Start looking on the left side, and you'll first pass an Esso station, then a Shell station, and finally a Caltex station. About 30 m past the Caltex station, turn left onto the road opposite the Pranburi Police station. Just before you get to the turn-off, there will be a sign telling you to turn left for Khao Sam Roi Yot National Park and Phraya Nakhon Cave. That's the correct road to turn left onto.

Follow that road to the end - 3.7 km - turn right, then immediately left at the little police station. From the police station, drive 16.5 km straight ahead towards the entrance to the park. After 16.5 km you'll see a Thai temple, Wat Phu Noi, on the right. Turn left opposite the temple and drive about 2 km until you come to the beach. Turn left on the beach road. Dolphin Bay Resort lies 60 meters ahead - it's easy to recognize by the two large swimming pools and big water slide! Parking is at the rear of the resort. Turn left onto the access road which runs along the far wall of the property.
