Chiangdao
Near to the famous Chiang Dao caves is a guesthouse called "Malee's Nature Lovers Bungalows".  It's a family owned guesthouse at the bottom of the  2,175 metre high Mt. Doi Chiangdoa, with attractive prices and a very good kitchen -  recommended!
From here we start to our last leg:

Day Four:
We  start out into a foggy morning.  Large drops of fog condense on my skin.  It is bitterly cold and my arms and legs are blue on the long descent.  But not for too long, and we again have to pedal and my body warms up again.  Initially we ride on tarmac roads along side rice plantations, where woman are singing and chatting at work.  Conspicuous are many signs in German colours including the sign of the big chemical  factory of Bayer Leverkusen.  I do not want to know how much pollution they have on their fields.
Then we turn off left into the foliage.  Looks like "the Road to Nowhere", but eventually we reach another hill-tribe village.  We are a bit astonished to see other tourists.  They are hikers, who have just finished their highlight "spend a night in a hill - tribe village" and are now buying souvenirs before leaving.  It looks as if the village is very used to having tourists as guests.  They have a large hut for guests as well as a small look-out to watch the natives. Hmm, reminds me too much on a zoo.  I don't like this.
Anyway, we eat a bit of our own food (I give a banana to  small boy who ogles at it for minutes) and we again go our own way on dirt roads and foot paths. Somehow my guide manages every midday to arrive at a small village, where we can have a soup in one of those noodle shops.

 

 

After all this effort I need to relax.  Best to do on an island.  Some impressions of  Ko Chang near to the Kambodian border are  here...
