Practical information about Wat Phra That Doi Suthep
A fifteen kilometers from Chiang Mai, the temple is accessible by a winding road up the mountain.
There is a Doi Suthep Line departing fromthe city, a little before Chiang Mai zoo and taking you to the temple for 30 THB per person. The red pick-ups of this line only leave when they have 10 passengers (or ask everyone to pay a little more). From Chiang Mai historical center or anywhere in the city, take a red pickup and tell Doi Suthep bus station to be dropped at the place from where the Doi Suthep Line departs (30 THB per person from the historical center). When you come back from Doi Suthep, you can be dropped directly at Thapae Gate by these same red pick-ups for 60 THB.
Otherwise, red cars offer you to take you to Doi Suthep from the city, wait for you when you visit and bring you back in town for 400 THB (no matter how many people). If you are more than two, it's probably better than using the Doi Suthep Line.
Entrance fee to the Temple: 30 baht
