Meet your guide and driver this morning at 05:30 in the lobby of your hotel for a private transfer to Bangkok Southern Bus Terminal. From there, embark on a public minivan to Kanchanaburi. On arrival, meet your guide Tik who will accompany us for the rest of the trip.
At around 10:30, we'll board a local taxi truck (a.k.a. songthaew) and head west towards Sai Yok National Park. While Kanchanaburi tends to become very busy in high season, Sai Yok National Park remains a hidden gem visited mostly by locals (entrance fee to the park not included and to be paid on the spot; THB 300).
Time to board our private floating raft and enjoy a local lunch, after which our raft will be pulled by a long-tail boat until we reach a quiet curve in the river. Surrounded by nature, we'll hear...nothing. Except the chirping of the birds or a tribe of monkeys arguing over a piece of fruit.
At 16:00, it's time to get our kayak on straight from the raft and cruise downstream through the national park. We'll pass a couple of local accommodations and floating rafts along the way, and then enter an uninhabited stretch into the national park until we reach our destination.
We'll receive our basic camping equipment and have some free time to plant our tents. Feel free to use the camp bathroom for a quick shower, or just jump in the river to cool off and then help the local fishermen catch dinner.
Speaking of dinner, follow the lead of the local cooks who will explain how to barbecue in the traditional way (on the campfire, of course.) Enjoy Tik's tall tales of the jungle life and your fellow WeCampers' company, and let's get the party started.

Meals: Lunch, BBQ dinner
Accommodation: Overnight under camping tent
Transportation: Bangkok Hotel to Bangkok Bus Station by private minivan, Bangkok Bus Station to Kanchanaburi Bus Station by public minivan, Kanchanaburi to Sai Yok National Park by local songteaw

No real rush to get up, but we will most definitely enjoy a tasty rice soup, khaotom, the most traditional of Thai breakfasts and a perfect dish to settle our morning stomachs.
We'll leave camp for a quick jaunt to the local village to introduce ourselves, led by our WeGuide. Depending on the time of year, we'll take part in some farming. We'll bet there's at least three kinds of fruit here that you've never heard of. We'll head on towards the local village and join the community for an informal cooking class.
With a full stomach in tow, we'll follow our jungle guide and hit the trail into the thick forests of Sai Yok National Park. While we're walking, we'll notice the landscape shifting rapidly from traditional crops and civilization to large bamboo bushes and dense foliage. Arrive at Camp Tuay!
We'll plant our tents for the night and relax, listening to the gentle forest sounds and enjoy the breeze. For those that can't get enough hiking around the jungle, there's enough time to go for another hike with our jungle guide while the rest of us start preparing the campfire.
Learn how to start a fire from our local experts, using only two pieces of bamboo and some brushwood. If you haven't done this before, be prepared for some frustration and (eventually) a sense of real accomplishment as you rediscover one of the most basic skills that define our species. Our fire roaring away, we'll prepare our dinner. Follow our guide to pick herbs and mushrooms to prepare an authentic jungle curry. Then chill as the jungle sounds take over our camp.

Meals: Breakfast, lunch, dinner
Accommodation: Overnight under camping tent

We'll get our breakfast on, cooked in bamboo shoots. We'll enjoy our last couple of hours in the jungle before packing our equipment and hiking back to the local village by the river. We'll have time to take a shower, return our WePack, and enjoy some local refreshments and a light lunch.
We'll cross back over the River Kwai by longtail boat and meet our songthaew driver on the other side. We'll head back to Kanchanaburi Town, arriving around 16:00.
