The most common way for travellers to enter the country seems to be by air. According to the website Lonely Planet, getting into Myanmar is problematic: "No bus or train service connects Myanmar with another country, nor can you travel by car or motorcycle across the border – you must walk across.", and states that, "It is not possible for foreigners to go to/from Myanmar by sea or river." There are a small number of border crossings that allow the passage of private vehicles, such as the border between Ruili (China) to Mu-se, the border between Htee Kee (Myanmar) and Ban Phu Nam Ron (Thailand) (the most direct border between Dawei and Kanchanaburi), and the border between Myawaddy (Myanmar) and Mae Sot (Thailand). At least one tourist company has successfully run commercial overland routes through these borders since 2013. "From Mae Sai (Thailand) you can cross to Tachileik, but can only go as far as Kengtung. Those in Thailand on a visa run can cross to Kawthaung but cannot venture farther into Myanmar." [SEP] Knowledge 3: Geography of Myanmar
