Hun Nal Ye and Bombil Pek

Months ago I went to Hun Nal Ye. It is a natural place. I swam in a cold river, and I did canopy [I am not sure what you mean here; did you mean the word "camping"?]. I walked to see a water-fall waterfall. I rode a horse. I camped near a river. The next day I went to saw see some caves. I did rappelling [you can also say "I rappelled"] to enter to the caves. The rapel has was seventy meters [you can also say "seventy meters long"].
