If you are flying in to Bangkok Suvarnabhumi Airport than one of the easiest ways to get to Cha Am is by car.
However, if you are visiting Thailand for the first time, driving is not something that is recommended, especially after a long flight. If you have some experience of driving in Thailand then the journey down from Bangkok can be fairly straightforward.
To leave Bangkok for the direction of Cha Am you need to drive to the Rama IX Bridge and then join the Rama II Road and follow signs for Samut Sakhon. You now need to stay on this road for approximately 85km until you start to see signs for Phetchaburi. Right at the end of the Rama II Road the highway splits into two. The left hand lane is signposted ‘Phetchabri’ and the right hand lane is signposted ‘Ratchaburi’. You need to make sure that you exit left for Phetchaburi.
You will now be on the Phet Kasem Road or Thanon Phetkasem as it is known to Thais. This is the main highway that heads south, to Hua Hin. Once you are on this road, it is just a matter of simply following the signs for Cha Am.
When you are about 30 minutes away from Cha Am you will pass Phetchaburi town. As you drive past the town you should see a Big C supermarket on your left hand side, keep on going and you will start to see signs for Cha Am beach. Once you get to a set of traffic lights that have a green sign above them that is labelled ‘Cha Am Beach’ turn left. You will now be on Narathip Road, carry on straight until you can see the beach.
