The best of the elephant trekking operations available in puket that we found is called "Kok Chang Safari". We enjoyed interacting with the "White Palmed Gibbons" that freely roam the nearby jungle and come out to visit people when they are in a playful mood. Everyone's favorite is "Charley" a seven year old, black male that loves personal grooming and searching unwary visitor's bags for new toys. "LumYai" is an eight year old tan colored female who loves mangos, personal grooming and swiping sunglasses and sodas so please be careful of your drinks. Feed the elephants bananas before you begin your 45-degree angle trek up and back down the mountain jungle trails on top of these gentle pachyderms through a working rubber plantation. If you have a sense of adventure your Mahout (Elephant Keeper) will jump off and let you take over the driving on the way down the mountain after some great photos from the summit. We got more information about this and more activities in puket by contacting puketrichard from the tripadviser forums.
