Here is a little more on Kanjanaburi
Kanjanaburi - a weekend from Bangkok
At just over two hours drive from Bangkok, Kanjanaburi offers a good weekend break or even a day trip for the family with pleasant views, clean air and more importantly cheap beer.
We were invited to the province by friends that live there; they had recently moved from Bangkok after they had built a bungalow on 6 rai of land for just over 1.7M baht. Their location was a bit remote with a 12km drive to town but the air was clean and the twisting country roads offered a more interesting drive than the usual straight roads I had got used to in the LOS.
On arrival in Town Friday evening we met up by the famous bridge over the river Kwai, the restaurant offered a verity of fresh fish from the river served in local style from about 70baht to 300baht a dish. A large bottle of chang was fairly priced at just 65baht considering this place is such a tourist attraction.
Saturday we were invited to go to the beach for lunch. The beach is in fact a stretch of a sandy river bank on the east side of town.
Surprisingly it was just like any typical Thai beach with deck chairs, parasols dogs, sales and massage. The food menu was all in Thai and there were no photos to help those of us who can’t read Thai. Rather than sea fish, local river fish was offered at a pleasantly local rate and a big bottle of chang was just 40Baht.
The Beach also offered Jet Ski, boating and swimming. The Jet Ski 600cc Yamaha was reasonably priced at just 500baht for 20min, (1500baht in Hua Hin).

The friendly locals just fell in love with my son
