We are so sorry to hear that our guests are dissatisfied with our service!
It was clearly a missunderstanding because it says that you have 4 hours inside the National park and that tour lasts for around 6 hours (+lunch) altogether with the speed boat!
We unfortunately can’t affect the weather, its summer so you should have expected high temperatures. Also, we cant affect the water on the boat which is owned by the national park.
Regarding the swimming under the waterfalls, this is the first year its forbidden, but we hope they will allow it again soon.
