In Bang Krachao, you will not be completly lost in the nature, but if you go on the small cement elevated roads, it will be a big change comparing to bangkok city for sure ! But be careful, these small roads can quickly become a maze where you might have some difficultiehs to locate you.
There are at least 3 things to do during your visit in Bang Krachao: stroll in the nature on your bicycle on the cement small paths, go to Bang Nam Phueng Floating Market and relax in Sri Nakhorn Kuan Khan Park. You'll even have the opportunity to see a beautiful statue of Ganesha....

Another lesser known option but it became my favorite one because you are quickly in the heart of the small elevated roads crossing nature and houses, it is to go to Wat Bang Na Nok in Samut Parakan (which is located HERE) then take a boat to cross the river (5 THB), you'll arrive at Wat Bang temple Nam Phueng Nok where you have bicycle rental shops (50 THB per day) and just after 3 minutes, you are at the heart of what bang krachao is about and quickly arrive at the nice Tree House Café.
