From Chiang Mai Zoo at the foot of the mountain and at the end of Huay Kaew Road, a good road winds its way up Doi Suthep for 15 kilometres before reaching the car park and cafe area at the temple entrance. From here there’s either 309 steps or a 30 baht tram fare to negotiate before you reach the temple proper. The road gets very steep so if you’re going up there on a motorbike please take care!
