Visa Information

Passport Validity Note

Your passport must expire at least six months after arrival and contain one blank page, or immigration may refuse entry.

History

Khao Sok’s wider region reveals its history through Rajjaprabha Dam, active temples, archaeological collections and the Buddhist heritage of Chaiya.

Culture

Culture around Khao Sok appears in village routines, forest knowledge, farming, cooking and the traditions of Cheow Lan’s boat crews.

Events

Khao Sok has few fixed festivals, but seasonal celebrations nearby can bring food, faith and community traditions into your journey.

Entertainment

Entertainment in Khao Sok stays low-key, favouring sociable village evenings, wellness and nature-led leisure over organised nightlife venues or clubs.

Top Attractions in Khao Sok

Khao Sok’s standout sights combine reservoir scenery, limestone formations and forest waterfalls, spread between Cheow Lan Lake and Khlong Sok.

Facts About Khao Sok

Khao Sok brings rainforest, limestone karsts, rivers and Cheow Lan Lake together within Surat Thani’s protected landscape in southern Thailand.

  • Khao Sok National Park was established on 22 December 1980 and covers approximately 739 square kilometres.

  • The park spans areas of Phanom and Ban Ta Khun districts within Surat Thani Province.

  • Park headquarters are in Khlong Sok subdistrict, near the village used as the main base for rainforest trails.

  • Cheow Lan Lake occupies the park’s eastern side, with boat access near Rajjaprabha Dam in Ban Ta Khun.

  • The lake is a 185-square-kilometre reservoir, created after Rajjaprabha Dam was completed in September 1987.

  • Evergreen rainforest, limestone mountains, caves, streams and waterfalls form the park’s varied landscape.

  • Protected wildlife includes Asian elephants, Malayan tapirs and several rare birds, although sightings are never guaranteed.

  • Khao Sok should not be confused with Khao Lak, the Andaman coast resort area in neighbouring Phang Nga Province.

  • Thailand follows Indochina Time, seven hours ahead of GMT and six hours ahead during British Summer Time.

Tips for Visiting Khao Sok

Careful planning matters in Khao Sok, where two separate visitor areas, tropical weather and limited transport shape every practical itinerary.

  • Plan Khlong Sok village and Cheow Lan Lake as separate stops; travelling between them requires an organised road transfer.

  • December to April is generally drier and busier, while May to November usually brings more frequent rainfall.

  • Rain remains possible throughout the year, so avoid building an inflexible itinerary around completely dry weather.

  • Reserve floating accommodation early and confirm the included boat transfer, meals, electricity hours and departure arrangements.

  • Check official park updates shortly before visiting, as trails, caves and water activities may close temporarily following heavy rain.

  • As of August 2026, foreign visitor admission is 300 baht for adults and 150 baht for children; verify current rates before travel.

  • Ask whether quotations include national park admission, pier charges, guides, boats, meals and transfers before confirming an excursion.

  • Keep Thai baht available for small purchases and locally collected charges, particularly before departing for Cheow Lan Lake.

  • Allow generous time between a lake stay and an onward flight because the journey combines boat and road transfers.

  • Accommodation names can appear under Khao Sok, Khlong Sok, Cheow Lan or Rajjaprabha; confirm the precise collection point in writing.

  • Some longer forest routes require a guide or ranger approval, so check arrangements with the visitor centre before setting out.

What to Pack

Pack for heat, humidity, sudden rain and boat transfers, keeping luggage light enough for Khao Sok’s varied accommodation and activities.

Travel Advice and Safety

Check FCDO advice, arrange comprehensive insurance, follow park instructions and keep emergency contacts accessible throughout your stay in Khao Sok.

Is It Safe to Travel to Khao Sok?

Khao Sok is generally suitable for British travellers, and current FCDO advice does not place Surat Thani or the national park within an area advised against travel. However, no journey is risk-free. Its remote rainforest setting, variable weather and road and boat transfers require sensible preparation, reputable operators and insurance covering planned activities.

Key Safety Considerations

  • Heavy rain and caves: Lakes, caves and waterfalls can experience dangerous flash flooding. Enter caves only with an authorised guide and leave immediately when instructed.

  • Boats and swimming: Wear a properly fastened lifejacket aboard longtail boats and during water activities. Swim only in areas approved by park or accommodation staff.

  • Road transport: Thailand has a high road-accident rate. Use reputable transfer providers, and only ride scooters with the correct licence, insurance and helmet.

  • Heat and insect-borne illness: High humidity can contribute to dehydration, while mosquitoes may transmit dengue, Zika and other infections. Follow current TravelHealthPro guidance and seek medical help for concerning symptoms.

  • Wildlife and animal contact: Never approach, feed or touch wild animals. Obtain urgent medical advice after any animal bite or scratch because rabies occurs in Thailand.

Local Laws and Culture

  • Respect for the monarchy: Criticising Thailand’s monarchy is illegal. Avoid negative remarks, gestures or online posts about the Royal Family.

  • Cannabis and vaping: Recreational cannabis and all vapes are illegal. Medical cannabis requires a Thai prescription and cannot be taken abroad.

  • Drone regulations: Check CAAT and NBTC registration requirements. Flying inside Khao Sok National Park also requires permission from park authorities.

  • National Park protection: Do not remove plants, rocks or wildlife, enter restricted areas or leave litter. Offences may result in prosecution.

  • Respectful behaviour: Dress modestly at temples, remove shoes inside worship buildings and avoid pointing feet at Buddha images or monks.
