Tee Lor Su in the Karen language means the black waterfall or the great, awesome waterfall which is very appropriate. It originates from a stream called Huai Klo Tor and is about 900 metres above average sea level and is 500 metres wide and runs down in steps approximately 300 metres high. The first level is enclosed by lush green forests and an expanse of rocky ground fit for relaxing and walking around. The secound level is a cliff of grand yellow limestone covered with a curtain of water running down to the bright green pond. The third and highest level is simply unapproachable for visitors due to the very strong rapids. Alternatively, tourists may also trek to the beauty spot at another hill that is located right opposite to this fall, where one can have a whole view of the fantastic Tee Lor Su Waterfall.
