We did the "Journey to Waimea Canyon". The tour was excellent - driven on a big bus to the canyon with some other stops. The canyon was completely amazing! I could have just stayed there looking at it, if not for time to return and all the sun exposure I'd already had on my fair skin.
Our guide, Tito, was very knowledgeable but not the friendliest guy ever.
My husband says - If you think you want to book a helicopter ride on Kauai, do it early (after checking on their cancellation policy) even if it looks like rain the day before. The company will tell you if it's not a good day. We didn't book for fear of rain, then there was no availability when the weather cleared up.
