Many of the more frequented waterfalls require a km or two hike on well marked and maintained trails, which are good for getting a taste of jungle hiking without committing to a serious trek.
Another good option is the Kong Kaew trail, which starts behind the Visitor Centre and runs about three kilometres with periodic signs providing information on the park's flora and fauna.
This trail also goes past Kong Kaew waterfall, and if you continue on it's possible to access a different trail for another seven km before ending at Haew Suwat waterfall. The trail system becomes more complex and trail markings more scarce the farther you go, however, so bringing a guide along for this further stretch is recommended.
It is also possible to explore deep into the jungle on overnight or multi day treks, and a guide book highlighting possible routes may be purchased at the Visitor Centre. While visitors are free to choose which trails they would like to trek (assuming they're open at the time), for a serious trek it is required by the park that a certified park ranger goes along.
