^ How far up do the boats go ? just to Sri nakarin road ? I know the khlong goes all the way out to Lad Krabang, near the airport.
I've seen the boats going past Wat Mahabut, and thought it would be a nice trip.

The boats turn around at Sri Nakharin but if there are other boats at the terminus it is possible to haggle with to take you further if you want but you're looking at 200B an hour +.
The canals go a sight further that Lad Krabang though and there are some beautiful stretches of canal especially behind the airport and beyond.
