Welcome to the board rellim. We have been to roaring river 3 times bringing newbies the last 2. Myself I have found every time was a different experience. I have swam in a couple different locations in the caves which was really cool. There is 1 swimming hole where you can swim through a tunnel. Another part I really enjoyed was there was a band playing in the caves, that was an incredible feeling. I can't even explain how that felt but I had tears running down my face like Niagara Falls.
Something or someone just came over me for reason or another. No guide is the same there if you get a chance check it out.
Cheers
