I have been to Doi Chiang Dao, but seen very little in comparison to this exciting trip, probably I was not at the right time and/or I went the wrong places.
What is the very best season to visit? What months should certainly be avoided?
What areas did you visit? I was mainly there for birds the fist time, but if/when I go back the butterflies (and moths) will take first attention spot. I went to Temple Area, Den Ya Kat Substation and a bit on the road through the national park - but not far as I did not have my own transport. Can you give some advice about the best areas to go for butterflies?
