Ayudthya and Lopburi- by Ekachai

From the Bang bua thong ring road, we travel up north to Pathumthani
via
Hw#347.
Pitstop in Ayuthaya for gas on bike and coffee for riders seems perfect
for
the distance.
From the back of Ayuthaya behind Wat Chaiwanaram, we travel north again
to
Ampur Bang pa Han.
At Ampur Bang pa Han, we take left turn into Hw#3196 (a 1+1 highway)

Highway#3196 is one of the most winding road within Bangkok vicinity.
The highway is running along the irrigation canals from Ampur Maharatch
upto the City of Lopburi.
Some 40 kiliometer perhaps of varying degree curves from the 30 to 45
to 90
degree with varying length.
