Top 10 rules to avoid an elephant squishing your car
Stay at least 30 metres away in your car and slowly back up to keep your distance if the elephant approaches.
No flash photography.
Do not honk the car’s horn or make other loud noises.
Do not turn off the engine and be ready to drive away at any time.
Do not get out of the vehicle to take photos.
Turn off your headlights if encountering elephants at night. Do not flash headlights or other lights at them.
If surrounded by elephants circling your car, move towards a spot in the circle with no elephants.
If the car in front of you backs up, please back up as well, as it might be an emergency situation.
Do not get out of the car and approach the elephant.
An elephant’s best senses are hearing, smell, and vision. If you turn off your engine, the elephant will approach and use these senses to investigate, by looking at, smelling, and listening to your car.

Tourists warned about thieving monkeys in Khao Yai National Park
Officials at Khao Yai National Park, north east of Bangkok, are warning visitors to be aware of rogue monkeys that may steal their belongings. They say tourists who camp overnight need to be particularly vigilant, particularly when preparing food.
Thai Residents reports that with the current cooler weather coinciding with high season in the national park, the increase in visitors also brings more monkeys and they don’t just target tourists. Local villagers are also struggling to protect their belongings against the cheeky primates. One coffee shop owner within the national park says the monkeys regularly break cups and bottles.
