The Palau Tourism Authority says large visitor numbers to the Rock Islands and a popular snorkelling spot is having a negative impact on the environment.
The Koror State Government is hiking the 10-day pass to the Rock Islands and Jellyfish Lake from June the 1st, to maintain its conservation efforts.
The Marketing Manager at the Tourism Authority, Ngedikes Bechesrrak, says the large number of visitors who snorkel in Jellyfish Lake has reduced jellyfish numbers.
"The visitors to Jellyfish Lake and the Rock Islands have a big impact on our environment and Koror State put that increase there to be able to fund people to protect and to maintain the Rock Islands and to make sure that it is well protected."
Ngedikes Bechesrrak says most visitors to Palau are from Japan and she says they can afford the increase in visitor permits.
