This is a fabulous temple, on par with Doi Suthep near Chiang Mai. It’s very worth a half day trip if you are in Chiang Mai. The temple complex is also quite a bit more peaceful and serene than you are likely to find in more tourist heavy areas and I even saw a number of people practicing walking meditation. You can visit in a tour or hire a driver. There are some English language explanations throughout the temple to provide a bit of background. The national museum is also next door and I wanted to visit but unfortunately was closed due to a holiday when I was there. The museum is generally open Wednesday through sundays but yes also closed on holidays.
