Which to use, and roughly what to pay
You do not need a car in Hua Hin. Between the apps, the local pickup buses and a short taxi ride, getting about is cheap and easy — it is just a question of which one suits the journey.
The default for most visitors, and rightly so: the price is fixed in the app before you accept, so there is nothing to negotiate and nothing to misunderstand. It works in English, you can pay by card, and you can see the route. Coverage in central Hua Hin is good; further out it thins. Bolt is worth installing as a backup.
Metered taxis are much rarer here than in Bangkok. Mostly you will find private cars and minivans working to an agreed price. That is fine — agree the number before you get in, and confirm whether it is per person or per car.
The converted pickups with two benches in the back, running fixed routes along the main roads for a few baht. Cheap, frequent and the most local way to travel.
Excellent along the main strip, useless for reaching a specific address off it.
Quick, cheap and everywhere. Agree the price first, take the helmet if offered, and use your own judgement after dark.
The airport is the exception. Getting to and from Bangkok’s airports is a long drive and not something to improvise at the kerb with luggage. Book it in advance at a fixed price.
