Since we were staying one night in Kanchanaburi, we booked a two-day private car charter. The car company contacted us via email three days before departure to confirm the departure time and itinerary. Safari Park is further away and requires an additional charge. The driver was very friendly, communicating with us using simple English and Google Translate. The journey from Bangkok to Kanchanaburi takes about 2.5-3 hours. When we told the driver we needed a restroom break, he stopped at a gas station for us. On the way to the hotel in the evening, he even asked if we wanted to stop at a convenience store to buy anything. The long drives between Bangkok, Kanchanaburi, and various attractions were always smooth and safe with the driver. Upon arriving at attractions, the driver, although not obligated to be a tour guide, would tell us what there was to see and even helped us take photos. For example, at the Bridge over the River Kwai, he told us what time the train would pass, encouraging us to stay a little longer to see it. Overall, this private car charter service allowed us to have a wonderful two-day, one-night stay in Kanchanaburi.
