This snapshot gives a quick look at the park's qualities, helping you grasp its scope and offerings before diving into detailed planning.
The park experiences three distinct seasons, each offering different advantages. Temperatures fluctuate, and humidity shifts throughout the year.
The cool season from November to February brings comfortable weather. Daytime temperatures typically range from 20°C to 28°C. Nights are cooler, dropping to 10°C to 20°C, specifically at higher elevations. Humidity stays low, and precipitation is minimal, making for clear skies. The hot season from March to May sees temperatures rise significantly, often reaching 30°C to 38°C. Humidity increases, and occasional thunderstorms may occur, notably in May. The heat can be intense in open areas. The rainy season, from June to October, has abundant rainfall. Temperatures generally range from 25°C to 32°C. High humidity remains present. Afternoon downpours are common, and these can be heavy. Water levels in the park's waterfalls are at their peak during this time. Some trails may become slippery, and certain areas might have strong water currents.
November to February. Pleasant weather for activities, comfortable temperatures, low humidity, clear skies. Ideal for hiking and wildlife spotting. Higher prices, more visitors.
May-June & October. Fewer crowds, tranquil experience. Lush green landscape, gaining waterfall strength. Humidity and rainfall increase.
July to September. Spectacular waterfalls, fewer tourists, lower prices. Heavy rainfall can disrupt activities, some trails close. Leeches are prevalent.
Hiking and wildlife spotting finds its optimal period in the Cool Season (November - February). Favorable temperatures and lower humidity make long walks comfortable. Animals stay more active. Waterfall viewing sees its most impressive flows in the late Rainy Season (September - October) and early Cool Season (November). The water volume stays high, creating powerful cascades. Birdwatching is possible year-round. The dry season (Cool and Hot) may allow easier access to trails and better visibility through less dense foliage.
Many nationalities get visa-exempt entry for tourism, typically allowing a 30-day stay. This stamp appears upon arrival at international airports or land borders.
Travelers from certain countries may become eligible for a VOA, usually granting a 15-day stay. This process involves completing an application and paying a fee at designated counters upon arrival.
If your nationality does not qualify for visa-exempt entry, or for longer stays, get a tourist visa in advance from a Royal Thai Embassy or Consulate.
Exchange foreign currency at banks, exchange booths, or airports. Dedicated exchange booths in towns offer better rates. ATMs are widely available in Pak Chong, but Thai banks often charge a transaction fee (around 220 THB).
Most hotels, larger restaurants, and supermarkets accept credit cards. Smaller shops, local eateries, and street vendors mainly prefer cash. Carry enough cash for daily expenses, especially in the national park or local markets.
Tipping is not generally expected but appreciated. Round up bills in casual eateries (20-50 THB). Upscale restaurants might add a 10% service charge; if not, 5-10% is suitable. For drivers or guides, 100-300 THB depending on service quality.
