Meet your driver in the early morning at 5:30 in the lobby of Chamberlain Hostel and hop in the van to Bangkok Southern Bus Terminal. From there, embark in a public minivan to Kanchanaburi. On arrival you'll meet your guide who will accompany you for the rest of the trip.

At around 10:30, you'll board a local taxi truck (a.k.a. songthaew) and head west to Sai Yok National Park. While Kanchanaburi tends to be very busy in the high season, Sai Yok National Park remains a hidden gem visited mostly by locals. Please note that the entrance fee to the National Park must be paid locally, expect to pay THB$300. Now it's time to board your private floating raft and enjoy a local lunch, after which the raft will be pulled by a long-tail boat until you reach a quiet curve in the river. Surrounded by nature, you'll hear...nothing. Except the chirping of the birds or a tribe of monkeys arguing over a piece of fruit.

At around 16:00, it's time to get in your kayak right from your raft and cruise downstream through the National Park. You'll pass a couple of local accommodations and floating rafts along the way, and then you'll enter an uninhabited stretch until you reach your destination. You'll receive basic camping equipment and have some free time to plant your tents. Feel free to use the camp bathroom for a quick shower, or just jump in the river to cool off or 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 your guide's tall tales of jungle life and your fellow campers' company and get the party started.

No real rush to get up, but you will most definitely enjoy a tasty rice soup, khaotom, the most traditional of Thai breakfasts and a perfect dish to settle your morning stomachs. You'll leave camp for a quick jaunt to the local village to introduce yourselves, led by your guide. Depending on the time of year, you'll take part in some farming - there's at least three kinds of fruit here that you've never heard of. You'll head towards the local village and join the community for an informal cooking class.

With a full stomach in tow, you'll follow your jungle guide and hit the trail into the thick forests of Sai Yok National Park. While you're walking, you'll notice the landscape shifting rapidly from traditional crops and civilization to large bamboo bushes and dense foliage. You'll plant your 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 your jungle guide while the rest can start preparing the campfire. Learn how to start a fire from the 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. The fire roaring away, you'll prepare our dinner. Follow your guide to pick herbs and mushrooms and prepare an authentic jungle curry. Then chill as the jungle sounds take over the camp.

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