Exploring Hidden Thailand
Getting Around Thailand
Transportation in Thailand has improved vastly over the past two decades. The thrifty, excellent buses cover the whole country and can move you comfortably over long distances between all major destinations, like Kanchanaburi (a three-hour bus trip from Bangkok's south terminal) and Nakhon Ratchasima (a four-hour trip from Bangkok's north terminal). There are also reliable trains and reasonably priced domestic flights.
To get to more distant locations, you can usually find a combination of buses and other shared modes of transport to make the trip, but you may sometimes have to hire a taxi or rent a bicycle or motorcycle. The latter is more true in Kanchanaburi than in Nakhon Ratchasima.
When to Go
Thailand (except for the southern part) basically has three seasons: rainy (from around May to November), cooler and dry (from November to mid-February), and hot and dry (from mid-February to May).
If you are traveling to enjoy inland water attractions, like the falls in Kanchanaburi province, go during the wet season or at the start of the cooler and dry season. Otherwise, consider going between November and February when there is little rain and the temperatures are slightly more moderate. Of course, this is the high season for tourism in Thailand so you will be paying full fare and competing for seat and hotel reservations. You'll also find that there are extra services and options available since there is heavier traffic between touristed destinations.
Some nature parks restrict movement after sunset--this is the case with Erawan, which is closed after 6 p.m.--but most are free and open to all, especially people choosing to camp in the wild. Phimai's historical park area closes at 6 p.m.
