In the far north is Thailand's second-largest city and a center for excursions to the region's ancient and beautiful temples, the teak forests and their working elephants, caves and waterfalls, and journeys to visit the northern hill tribes. The main attractions are the Doi Suthep temple and elephant trekking. Doi Suthep is one of the most famous temples in northern Thailand. Perched high on a hilltop, it offers fine views over the city on clear days. The trip up can either be made via a funicular or a grand staircase with 400 steps. The banisters alone are worth a visit: a giant green-and-red glazed serpent winds its way down to end in a magnificent dragon's head. Elephant trekking in the surrounding countryside has become a big tourist buck earner in the last decade, but visitors should beware that some 'authentic' trips turn out to be just the opposite.
