Sap ChomphuArboretum was an exciting find for me. Theword arboretum makes the place sound boring but apart from learning about plants from fresh and dried specimens, here you can also enjoy three waterfalls and a fossil site (chunks of rock with seashell fossils are on display in the modest exhibition area).Unfortunately, on the day of my visit atropical storm hit many parts of the Kingdom. To minimise risk of injury or death,the trails to those attractions were closed. According to a local resident, this month is supposed to be the time when the three waterfalls are at their peak. AfterOctober, there may be less water on the cascades.
