If you wanna have fun and commute easily from place to place you can rent a motorbike but be careful that you wear the helmet otherwise you can be fined and in case if there is any accident

it would be too dangerous to ride without it,right ?
Howver I think it is a bit dangerous to ride the motorbike in Pattaya if you are Amateur. The way they drive and ride here are

but some people are used to it as they are being in the fast and the furious
Taxi is easily found everywhere but try to bargain then if you think the fare is not so reasonable.
Taking a walk is also a good idea, but I don't think you can walk from North Pattaya to Jomthien beach

. It's nice to keep fit for a short walk then since the temperature is always super HOT here!
P.S. However it is rainy season now in Thailand!
