This video was shot in a national park in the central province of Sri Lanka. The elephants of Wasgamuwa are notoriously aggressive and are known to attack without any obvious provocation. Wait for the end, the vehicle owners comment is priceless
In Ayutthaya Historic Park, tourists can ride elephants. Just outside the city is the elephant corral, where those elephants and their mahoots (keepers) live. Not well publicised, but you can visit there and see the elephants up close and personal.
