Khao Sok National Park (often misspelled as “Khao Son” in some itineraries) is one of Southern Thailand’s most impressive nature destinations, famous for its ancient rainforest, towering limestone cliffs, waterfalls, and emerald-green lake. It lies in Surat Thani province between the Andaman Sea and the Gulf of Thailand and covers more than 700 square kilometers of protected forest, rivers, and mountains.

The park has two main areas for visitors: the Khao Sok Village side, where you stay in jungle bungalows and join hikes or river activities, and the spectacular Cheow Lan Lake, known for its floating bungalows and dramatic karst scenery rising straight out of the water. Together, they make Khao Sok travel a perfect mix of soft adventure and quiet nature escapes.

Travellers come here to stay in floating raft houses, kayak between limestone towers, trek to waterfalls, explore caves, and look for wildlife such as hornbills, langurs, macaques, and (with luck) wild elephants or gibbons. Despite its popularity, Khao Sok still feels wild and lush, with dense jungle and a real sense of being far from the cities.

Warm, humid Khao Sok weather means this is a true rainforest experience year-round, with misty mornings, tropical showers, and deep green scenery at any time of year. The park also connects easily with Phuket, Krabi, Khao Lak, and the Gulf islands, making it a natural stop between beach destinations.

Wondering how to get to Khao Sok? The park is inland but very well connected by road to Surat Thani, Krabi, Phuket, Khao Lak, and the Gulf ferry piers, with public buses, minivans, and private transfers running daily.

By Air (Nearest Airports)

There is no airport inside the park, so you fly to a nearby city and continue overland:

  • Surat Thani Airport (URT) – usually 2–2.5 hours away by bus, minivan, or private transfer.
  • Phuket International Airport (HKT) – around 2.5–3.5 hours by road, depending on route and traffic.
  • Krabi International Airport (KBV) – typically 2–3 hours by minivan or private car.

Many guesthouses and tour operators in Khao Sok arrange direct transfers from these airports, which is often the most convenient option for first-time visitors.

By Bus, Minivan & Train Connections

Overland travel is straightforward, with regular services from several hubs:

  • From Surat Thani (town or train station) – local and tourist buses go along Route 401 and stop at Khao Sok; the journey is usually around 2 hours.
  • From Phuket, Khao Lak, Krabi, or Ao Nang – shared minivans and buses run daily, often taking 2–4 hours depending on starting point.
  • From Bangkok – many travellers take an overnight train or bus to Surat Thani, then connect by bus or minivan to the park.

Combined tickets (train or bus plus onward bus to Khao Sok) are widely sold at stations and travel agencies, making Khao Sok travel easy to organize.

Because it is true rainforest, Khao Sok weather is warm and humid year-round, with rain possible in any month. Instead of “good” or “bad” seasons, it’s more useful to think about what kind of atmosphere you prefer.

Climate Overview

Temperatures generally range from about 22–32°C. The area is influenced by monsoon winds from both the Andaman Sea and the Gulf of Thailand, so showers can be heavy but help keep the forest green and the rivers and waterfalls flowing.

Seasons

  • Drier Season (roughly December–April) – less rainfall, more clear days, and slightly cooler nights. Great for trekking, viewpoints, and easier logistics.
  • Rainier Season (May–November) – more frequent, often intense showers, especially in late afternoon or evening. Trails can be muddier, but the rainforest feels at its most lush and waterfalls are stronger.

Best Time for Activities

  • Cheow Lan Lake trips & floating bungalows: possible year-round, with beautiful misty mornings in both wet and dry seasons.
  • Trekking & viewpoints: December–March offers firmer trails and slightly cooler conditions.
  • Waterfalls & very green scenery: May–November, when rainfall is higher.
  • Best balance of comfort & greenery: roughly November–February, when many travellers choose to visit.

Khao Sok transport is simple, as most visitors stay either in Khao Sok Village or on Cheow Lan Lake with transport arranged through their accommodation or tour.

Within Khao Sok Village

  • The village is small enough to walk between many guesthouses, restaurants, and the park entrance.
  • Local songthaews (pickup trucks) and taxis can take you to nearby viewpoints, river activity starting points, or the bus stop on the main road.

Cheow Lan Lake & Floating Bungalows

  • All lake trips start from Ratchaprapha (Cheow Lan) Dam pier, about 60–70 minutes’ drive from Khao Sok Village.
  • Longtail boats are used to reach floating bungalows and explore the lake; these are normally arranged as part of a guided tour or overnight package.
  • Once you are staying on the lake, most activities (kayaking, short hikes, cave visits) are organized directly through your raft house or guide.

Regional Connections

  • Guesthouses can book onward minivans or taxis to Phuket, Krabi, Khao Lak, Surat Thani town, or the ferry piers for Koh Samui, Koh Phangan, and Koh Tao.
  • Public buses on Route 401 stop at the junction near Khao Sok; your accommodation can arrange pickup from the bus stop.

A few practical Khao Sok tips help you enjoy the rainforest safely and comfortably.

Timing & Crowds

  • December–February is the busiest period, especially for lake trips and floating bungalows; book ahead if travelling then.
  • Shoulder months like November and March often offer a nice balance of decent weather and fewer people.
  • Even in rainy months, morning trips can be beautiful; showers often come later in the day, but plans should stay flexible.

What to Pack

  • Light, breathable clothing plus a light long-sleeve layer for evenings and leech/sun protection on the trail.
  • Good walking shoes or sandals with grip for muddy paths and slippery rocks.
  • Rain jacket or poncho, quick-dry clothing, and a small dry bag for lake and river trips.
  • Insect repellent, sunscreen, reusable water bottle, and any personal medication.
  • Waterproof phone or camera protection if you plan to kayak or join boat trips.

Cultural / Behaviour Tips

  • Remember you are in a national park: stay on marked trails, keep noise low, and never feed wildlife.
  • Dress modestly when passing through local villages or stopping in Surat Thani, Krabi, or smaller towns on the way.
  • Support local guides and small businesses; many tours are community-based and help preserve the area.

Safety & Transport Advice

  • Always follow guide instructions during lake trips, cave visits, and night safaris; conditions can change quickly in the rainforest.
  • Wear lifejackets on boats, especially during the wetter months or if you are not a strong swimmer.
  • Trails can be slippery after rain; take your time, use proper footwear, and consider walking poles if balance is a concern.
  • Check that your travel insurance covers trekking and boat activities in national parks.

Food & Insider Recommendations

  • In Khao Sok Village, try simple Thai restaurants and roadside stalls for southern curries, stir-fries, and fresh fruit shakes.
  • Most floating bungalows include set meals; expect homestyle Thai dishes with rice, vegetables, and fish or chicken.
  • Wake up early at least once on Cheow Lan Lake to watch the sunrise mist over the water – one of the park’s most magical experiences.
  • If you enjoy wildlife, consider a guided night walk or night safari for the sounds and sights of the jungle after dark.
