Kaeng Krachan National Park,Thailand

Kaeng Krachan National Park is Thailand’s largest national park (area approx. 2,915 km²) and one of the country’s most important conservation areas. Established in 1981, the park protects extensive evergreen and mixed deciduous rainforest in the Tenasserim Hills along the Thai–Myanmar border. It is a biodiversity hotspot, home to hundreds of bird species, many mammals (including Asian elephant, gibbon, leopard cat and sun bear), and rich plant diversity. The park’s intact forest and large protected area make it crucial for regional ecological connectivity and watershed protection.

Places to visit

  • Kaeng Krachan Reservoir (dam and lake) — scenic boat trips and waterside wildlife viewing
  • Pha Charoen/various mountain viewpoints — sunrise/sunset panoramas over forested hills
  • Pala-U and seasonal waterfalls — accessible hikes and swimming in certain areas
  • Dense lowland and montane rainforest — superb birdwatching and primate sightings
  • Night-time wildlife drives and ranger-led nocturnal walks

Unique Aspects

Best Time to Visit

Dry season (November–April) is the most accessible and popular time — clearer trails, better wildlife spotting and comfortable temperatures. Rainy season (May–October) brings lush scenery, active waterfalls and fewer visitors, but many dirt roads can be muddy or closed and some areas are inaccessible.

Weather Conditions

Tropical monsoon climate: warm year-round with the hottest months before the monsoon (March–May). Heavy rainfall from May to October; cooler, drier weather from November to February, especially at higher elevations.

Entry Fees & Permits

Park rules, fees and opening hours change periodically. Typical situation: park open daily roughly 06:00–18:00 (day visits); overnight stays, camping, trekking and vehicle access often require permits from the park office. Entrance fees usually differ for Thai nationals and foreigners, and small additional fees may apply for vehicles and cameras. Always check the official Kaeng Krachan National Park office or the Department of National Parks (DNP) website before travel for current fees and permit procedures.

Accessibility

By road: the park is reached from Phetchaburi and Prachuap Khiri Khan provinces; from Bangkok it is typically a 3–4 hour drive depending on your entry gate and conditions. Some internal park roads require 4x4 vehicles or ranger-driven access. Nearest major transport hubs: Bangkok (Suvarnabhumi/Don Mueang airports) and Phetchaburi train station. Public transport reaches nearby towns but private car or a booked tour/transfer is the most practical for entering the park.

Recommended Duration

At least 2 days / 1 night to explore reservoir viewpoints and a waterfall; 3–4 days recommended for deeper birdwatching, night safaris and multi-site hikes.

Clothing & Gear Tips

Lightweight, quick-dry clothing; sturdy hiking shoes, rain jacket (especially May–Oct), warm layer for cool mornings at higher elevations, insect repellent, sun protection, headlamp/torch for night walks, binoculars and camera. Bring a refillable water bottle and basic first-aid kit.

Local Food & Souvenirs

Facilities inside the park are limited — bring snacks and water or plan meals in nearby towns. In nearby Phetchaburi and local villages you can enjoy regional Thai cuisine and markets. Souvenir options include local handicrafts from Karen communities and packaged local snacks; support ethical and legal sellers and avoid purchasing wildlife products.
