About Pattaya

Pattaya's bay runs along the city, with Jomtien's quieter beach to the south and the islands of Ko Lan a short boat ride away. Water parks, the sanctuary of truth and the Nong Nooch gardens fill family days, and Bangkok is two hours by road. November to April is the dry season; the rainy months are quieter, and the nightlife runs year-round.
