Far outside of the bustling city of Bangkok, there is a magical place called Khao Yi National Park, a UNESCO site. Within this park are many 'hidden' waterfalls, which is not a misnomer at all, since you literally discover them as you explore the park. This particular waterfall is reached thusly: 1) take the Sky Train in Bangkok to the bus depot at the edge of town. 2) Grab a ticket for the bus headed to the town of Pak Chong (three hours one way, bring a book). 3) Since there is no official transportation to the park, find a local canopy truck that shuttles locals around and ask if they'll drop you off at Khao Yi. 4) Arrive at the park at 2:30 pm and get informed that the park closes at 6 (no problem), but that the last canopy truck back to Pak Chong is at 3:00 (problem). 5) Throw caution to the wind, stay at the park till 6 and hitchhike back to town.
Khao Yi is enormous, and it's best navigated with a car or a small scooter. This allows you to get deep into the park where you can begin hiking, watching wildlife and waterfall hunting. We were able to cover about 60 km over three hours, and 'discover' about six waterfalls. If national parks are your thing, this place is worth the journey.
And yeah, we did end up hitchhiking back to Pak Chong. A woman and her daughter let us ride in the back of their pick up (which was filled with boxes so we sat on top and held on to the roof). We received many smiles and waves from the locals along the way. Fiasco? I think not.
