Here's a good review for the Blue Hawaiian Helicopters’ Kauai Eco Tour (posted by Cruising Goddess):

Cruising Goddess

It is worth reading if you are considering this tour.   She gives pros and cons about the seating arrangement on the helicopter as well as what was actually seen on the tour.  Overall I think a positive review.

Blue Hawaiian Helicopter's Kauai Eco Tour

The have tours on all of the islands:

Big Island of Hawaii

Maui

Kauai

Oahu

Looks like many choices  ....   Also they have a virtual tour of the outside and inside of the helicopters they use.  Was very interesting.   Click on the link then look at the left side of the page for the virtual tours.

Important note on their website:   No scuba diving within 24 hrs. of departure
