Im going to Thailand, Patong Beach, and am not sure what to do exactly, i was thinking elephant rides and water rafting and cooking classes but im not sure what else to do and how to find where i can book in for these

Hi and welcome to the forum.
There is so much to do you will not we bored!!! For booking activities you should wait till you arrive, it will be lots cheaper. There are tour desks everywhere on the streets, literally.
For heaps of ideas check out Cathy and garys travel pages, there is more info here than you will ever need.

Quad Bikes

Just look for any tour desk near you hotel, they will have all sort of suggestions.

Plenty of elephant rides, one quite close to Patong on the road over to Karon.

Cooking classes best to Google cooking phuket.

Water rafting - you will need to travel outside Phuket for that.

Take a stroll down Bangla Road and you'll find all the activities you need.. the trouble isn't finding the activities it's finding the time!!

Patong beach is among the best beaches in the world...Every year many tourists come here to enjoy their vacations...Also many couples can also be seen here enjoying their honeymoon or dates too..One can enjoy the activities like scuba diving,water rafting,surfing,bungee jumping etc...
