THINK ABOUT THAILAND and animals at the same time and thoughts will probably turn to elephants. Well-trained elephants with brave and daring mahouts were crucial to the felling of teak forests around Chiangmai and in the North in the past. Visitors to Chiangmai can watch logging elephants at work at the elephant camp in the nearby Mae Taman's Elephant Conservation Camp, or more adventuresome visitors can visit the Center for Training Baby Elephants near the city of Lampang. Elephant riding has also become a popular and common feature of Hilltribe trekking throughout the North.
