Our tour was cancelled twice d/t large ocean swells re client safety. Shane and Vicki were both awesome to deal with. They demonstrated courteous and informative customer service and I was confident that their main value was client safety. I'm thankful we booked this tour very early in our time in Oahu. Unfortunately, my sister had to leave Oahu sooner and was unable to go on the tour and her ticket was promptly refunded. She was taken on a short boat ride tho, which she thoroughly enjoyed. Husband and I had an awesome time on this tour. We felt safe and the boat staff was excellent- safety was obviously the key concern. Mahalo to Dave, Dave and the energetic gal whose name I've forgotten (I'm so sorry). I felt that it took me more energy than I expected, to tread water and not have the cage sides hit me, than the website video displayed (there were some ocean swells pushing at the cage), but the experience of watching these graceful sharks swimming close to us was totally amazing and worth every penny spent! Mahalo North Shore Shark Adventures for helping us cross off an item from our bucket list.
