Bangkok has a lot to offer, but a beautiful beach unfortunately not. But that's no problem, from Bangkok to Pattaya it takes only about 3 hours, to Koh Samed just over 4 hours, Phuket by plane is also reached quickly.
This island is a true holiday paradise, actually too beautiful to tell others ;-)
Pattaya is an internationally renowned seaside resort, with beautiful beach and pleasant waters.
Phuket is a tourism stronghold, with many parties and beautiful beaches.
