Because helicopter is really needed, it's treated like public transportation. So it's almost like the cost of Uber ride on Bay Area. I think we paid like $20 or so for a 15-20 min flight. However, to reduce tourist abuse, you can only take the helicopter one-way. But when we visited, it was very low season and helicopter was pretty much empty and they allowed us to take a roundtrip flight which was quite amazing.
That being said, on our last full day we took a boat ride. Where the pilot showed us some of uninhabited islands. Like you read this in this article. He would point to a hut on a small abandon island and he would say: no one has lived here since 1998 (or something like that). On that same boat ride we hit some rainy weather, and part of the highlight of the trip is the boat going through this giant rock formation by the cliffs. It was almost like being inside the movie King Kong. It was one of the most thrilling experiences of my life.
One more interesting experience was arriving there. Firstly the airport is on this strange and scary location. Secondly, on arrival (because of high tariff rates) you see people buying cases of Coca Cola, etc at duty-free shop before officially entering into the country. I highly recommend visiting there.
