Get in 
From/to Bangkok: By plane: Surat Thani airport is the nearest one but you can also choose Phuket airport. By train: Surat Thani train station is the nearest one. Be careful: the southern line is very busy, advance booking is highly recommended. By night bus: There is only one night bus per day stopping at Khao Sok. In Bangkok, it seems that the only way to book and buy it is to go directly to the southern bus station in Bangkok (booking any other night bus sold by agencies is not recommended). In Khao Sok, it is possible to book and buy it in the local agency or at your hotel (ask for the real VIP bus, direct from Khao Sok to Bangkok).
From/to Ko Lanta, Ko Jum or Ko Phi Phi: 650-700 baht for Ko Lanta or Ko Jum; 550-600 baht for Ko Phi Phi.
From/to Krabi: Only one minibus per day, starting from Krabi at about 11:00; starting from Khao Sok at 08:30. Transit time is 3 hours. Price: 300-350 baht.
From/to Phuket or Khao Lak: There is a bus service (approximately one bus per hour; the last one starts from Phuket around 14:00). Transit time is 4 hours from Phuket and 2 hours from Khao Lak (including a 20 min stop in Takua Pa that you may use to visit the local market). Price: about 160 baht from Phuket.
From/to Surat Thani: Bus running approximately every hour. Transit time is about 2.5 hours. Price: about 120 baht. There is also a minibus service: departure every hour from 07:30 till 17:30 (but the last one can be canceled)
200 baht for foreigners, 100 baht for students, 40 baht for Thais. If you are told otherwise feel free to go directly to the park entrance and buy a ticket there.
Many tours will include the park entrance fee, something to take into consideration when choosing a tour.
Get around 
Walking is the primary mode of transportation, as the road to the park is only 2 km and the farthest one can walk into the park is about 20 km.
Rafflesia Flower: to see the Rafflesia flower you have to go when it is in bloom around late-Jan or early-Feb. The way to see it is not through the main entrance of the park. Go down to the intersection of the highway and the road to the park. From there, go right to km111 and on your right you will see a wooden ladder. Go up that and when you get to the first fork take a right. From there the little path crosses some streams and such so look hard if you can't find the trail again. This will take you most of the day if you start early (about 09:00), but you could be back in time to go to the temple with all the monkeys. If you find a tour group, just follow them until they get to a flower. The English guy at the restaurant next to the park said, "you don't need a guide, but if you go by yourself it's not guaranteed that you will see the flower." Don't forget to buy a ticket before you go.
Tours can include tubing down the river, caving, kayaking, and zipline riding in the forest canopy. Many tours will include drinks, food, and/or basic accommodation. Ask your guide in advance about dietary concerns (vegetarian or in Thai, "jay", for example), if lunch is to be provided for you on the tour.
Doing any 2-4 day tour in the national park will easily please any traveler. Your guesthouse can easily help set you up. Choosing a tour that involves at least one night in a floating raft house in the national park lake is an unforgettable experience.
Khao Sok 4 Days / 3 Nights
Day 1: Leave for the area around Khao Sok National Park head quarters in the morning from Phuket, Khao Lak, Krabi, or Surat Thani. Visit the elephant camp and explore nature by canoeing down the Sok River. In the evening, enjoy the sounds of the rainforest.
Day 2: Visit the jungle cave temple. Go hiking in the national park by yourself or by hiring a local guide. The trails inside the park are well marked and there are several waterfalls on the way. In Jan-Feb it's possible to find the world's biggest flower, the Rafflesia blossom.
Day 3: Continue to Chiew Lan Lake about 70 km away and depart from the Rajjabrapa pier. On the way to the raft houses, sail amidst spectacular rock formations and make a detour for Gulin of Khao Sok, a scenic place on the lake. Check into a simple bamboo rafthouse. Paddle a canoe to explore the lake and look for wildlife. Take a bamboo raft to a newly discovered dripstone cave. This tour can also be arranged from your resort. Morning Mist Resort offers a lodging discount when you book an activity.
Day 4: Value your stay in the wilderness. Get up with the sun. Take a canoe or arrange with the boat driver to go for a safari to scan the banks. Morning is the time of day when the animals are most active and if a branch in the canopy flicks from one side to the other, it is often a group of monkeys searching for their first meal of the day. Take a swim in the lake and head back to the pier by longtail boat. Transfer to ongoing destinations can be arranged.

Stay safe 
Don't go off trail without a local guide or a ranger.
Do not explore the "Namtaloo" or "Through" Cave (a cave with a river running through) if it is raining or if you think it is going to rain. Rain is frequent and can come on fast. Unfortunately people have died as a result of this. If you are with an experienced guide he will not take you if he even suspects a chance of rain.
Several places in town have high-speed Internet for 1 or 2 baht/minute. Some have headphones and Skype.
Go next

Across the street and to the right, a giant "Bus Stop" sign serves as a stopping point for buses heading to Khao Lak and Phuket. Tickets in advance are not needed. Buses come by every hour during the day.
