According to forum posts, a common itinerary for exploring Kanchanaburi includes visiting the River Kwai Bridge, the War Cemetery, the Death Railway Museum, and Hellfire Pass. Travelers have recommended starting early in the morning to visit Hellfire Pass to avoid the heat and then moving on to the museums and cemeteries in the afternoon.

Some travelers said that experiencing a train ride from Bangkok to Kanchanaburi or vice versa adds a unique element to the trip, as it allows one to experience the scenic route and the historical Death Railway. However, it's noted that the train often runs about 10 to 20 minutes late.

For many users, staying in or near Kanchanaburi town is recommended for better access to local attractions and services. Places like the Good Times Resort and Oriental Kwai Resort were frequently mentioned for their good location and services. The Floathouse, while appealing, is noted to be quite remote, about an hour away from most key sights.

Travelers have called out that adding a visit to Erawan Falls can be a refreshing addition to the itinerary. It's recommended to visit the falls early in the morning to enjoy the area before it gets too crowded and hot.

According to forum posts, Hellfire Pass is surrounded by several key attractions that enhance the historical and natural experience of the area. Travelers have highlighted the Sir Edward Dunlop Park, located on the property of the Home Phutoey Hot Spring Resort, as a notable site. It features exhibits dedicated to Weary Dunlop and other sections worth visiting such as Chalker’s drawings and paintings.

Some travelers mentioned the proximity of Hellfire Pass to other significant spots like the Krasae Cave and the Hintok River Camp, which are also situated along the historic Death Railway. Moreover, the area is close to the Home Phutoey Exhibit, which is dedicated to Weary Dunlop, a wartime surgeon, adding a rich historical layer to the visit.

For those interested in natural scenery, the nearby Sai Yok National Park offers beautiful views and opportunities for further exploration. The park is easily accessible and provides a tranquil environment contrasting with the historical gravity of Hellfire Pass.

According to forum posts, one popular way to travel from Bangkok to Kanchanaburi is by train from Thonburi Station. The journey is scenic and cost-effective, with tickets available at the station on the day of travel.

Travelers have called out the availability of buses and minivans from Bangkok's Southern Bus Terminal to Kanchanaburi. Buses are preferable for those with more luggage as they offer storage space. Minivans also operate on this route, offering a faster but possibly less comfortable journey due to limited space.

Some users opt for private transport like taxis or hired cars, especially when traveling in groups or seeking convenience. While more expensive, this method provides direct service to Kanchanaburi from Bangkok. Prices can vary, with some negotiations expected.

For many users, combining transport methods based on convenience and time availability is common. For instance, taking a train one way and a bus or taxi the other way is an option to consider for flexibility and experiencing different modes of travel.
