This was a top excursion for my teen/young 20 boys and I. We booked through Carnival, but glad to see anyone can book it because it was so much fun!!! It is high speed but not dangerous. It also isn't just speeding across the water. They stop and show you the wildlife and point out scenery while giving you information. It is anything but boring! Bevin was our captain and she was great! I wish I could remember the guides name because he was fantastic as well. We loved this excursion and saw many bald eagle, harbor seals and waterfalls. Highly recommend. And they provide all the gear to keep you comfortable (wet suit, goggles, face mask, etc). So much fun!
