Khao Sok National Park

Khao Sok National Park is one of Thailand's oldest and most biodiverse rainforests, dating back over 160 million years—older than the Amazon. The landscape is dominated by dramatic limestone karst mountains (hong islands), the emerald waters of Cheow Lan Lake, and countless waterfalls. It offers an authentic jungle experience that contrasts sharply with Thailand's coastal beach destinations, making it ideal for nature lovers, trekkers, and anyone seeking immersion in pristine wilderness.

The best time to visit is November through April, during the dry season. January and February are peak months when the Rafflesia flower—the world's largest bloom—can be seen in the jungle. Most waterfalls and caves are closed from June 1 to December 14 due to monsoons and safety concerns. March and April can be very hot, so early morning activities are recommended.

The park has two entrances: the west entrance at Park HQ (near Khlong Sok village) and the east entrance at Rajjaprapha Pier (for Cheow Lan Lake). The two entrances are 65 km apart and require over an hour of driving. Most visitors arrive from Phuket, Khao Lak, Krabi, or Surat Thani. Surat Thani International Airport is 105 km east of Park HQ, while Surat Thani Railway Station is in Phunphin District. Phantip Travel offices at the airport and train station can assist with onward transport.

Foreign visitors pay 300 baht for adults and 150 baht for children. Thai nationals pay 40 baht for adults and 20 baht for children. With a Thai ID card, work permit, or driver's license, foreign residents may qualify for the Thai rate at the gatekeeper's discretion. Tickets are valid for 24 hours only—keep your ticket if visiting both Park HQ and the lake on the same day. Some tour packages include the entrance fee.

Walking is the primary mode of transport within the park, as the road to Park HQ is only 2 km and hiking trails extend about 20 km into the jungle. Motorbike and bicycle rentals are available near Park HQ for exploring the surrounding area. To reach the floating rafthouses on Cheow Lan Lake, take a longtail boat from Rajjaprabha Pier.

Accommodation options fall into two main areas: guesthouses and resorts near Park HQ (ranging from 300 baht at Smiley's Bungalows to 5,500 baht at The Cliff and River Jungle Resort), and floating rafthouses on Cheow Lan Lake (typically 200 baht per person for basic options like Kraisorn Rafthouse, up to 38,000 baht per person for luxury options like Elephant Hills). Tree house accommodations like Khao Sok Nature Resort offer a unique jungle experience, while glamping options like Khaosok Boutique Camps provide air-conditioned luxury tents.

Most guesthouses have restaurants serving Thai and European dishes at 70-100 baht per meal. The hygiene standard is generally high—look for establishments displaying the "Clean Food, Good Taste" government certification sign. Fresh fruit shakes and juices are widely available at restaurants and convenience stores. Seasonal tropical fruits including rambutan, longan, pomelo, mango, mangosteen, banana, papaya, and guava are sold locally. There is one main road in Khao Sok village where guesthouses and bars are concentrated, including the Chill Out Bar, Rasta Bar, and Jumamji Bar, all serving similar cocktails at comparable prices.

The park offers tubing, caving, kayaking, and ziplining through the forest canopy. A suggested 4-day itinerary includes visiting an elephant camp, canoeing the Sok River, hiking to jungle caves with waterfalls (January-February for Rafflesia flowers), and 2-3 nights at floating rafthouses on Cheow Lan Lake with canoe exploration and cave visits. The Sonchana Farm and Elephant Sanctuary offers ethical elephant encounters with a cooking class. Jungle camping is only permitted December through April with an English-speaking guide and park ranger.

Do not go off trail without a local guide or ranger, as the jungle is dense and disorientation is easy. Never explore Nam Talu Cave (also called Through Cave, a river runs through it) if it is raining or if rain is forecasted—flash floods have killed people here. Monsoons arrive quickly, so guides will refuse tours if rain threatens. The monkeys at Sok Temple can be scared off by loud noises, so you may not see them after thunderstorms or fireworks. The Rafflesia flower hike requires a ticket and takes most of the day starting around 09:00.

Several places in Khao Sok village offer internet access at 1-2 baht per minute, with some providing headphones and Skype. WiFi is available at some resorts like Khao Sok Paradise Resort (free), Morning Mist Resort (free), and Khao Sok Riverside Cottages (in common areas). Mobile coverage is generally available but can be limited in deeper jungle areas.

Cheow Lan Lake (Chiew Larn) is 70 km from Park HQ and makes an excellent day trip if you don't overnight on the lake—take a longtail boat from Rajjaprabha Pier to see spectacular rock formations and visit floating rafthouses. The Rafflesia flower can be seen on a day hike starting early morning. Nearby towns like Surat Thani, Khao Lak, and Phuket serve as bases for visiting the park.

Mini buses depart from the main highway (opposite the park entrance) heading to Surat Thani every hour. Across the street, buses to Khao Lak and Phuket stop throughout the day—advance tickets are not needed. From Surat Thani, you can connect to train services, ferries to islands, or flights from Surat Thani International Airport.

A budget backpacker can expect to spend approximately 500-800 baht per night for basic bungalows, 70-100 baht per meal, and 300 baht for park entrance. Floating rafthouses range from 200 baht per person for basic options to 2,500+ baht for mid-range. Multi-day tour packages including accommodation, meals, and activities typically start around 1,500 baht per day. Bus transport to/from Surat Thani costs around 100-200 baht.
