We had rented a jeep for two days of adventure around the north shore. Our condo was in Ko Olina. The heads up on travel time is spot on, luckily we had the first tour so traffic was not so bad that early. You get to the harbor and it's just a little shack saying north shore shark adventure, easy to find though. We had captain Mike and Jewels on our tour, very knowledgeable and helpful. Answered all questions. Water was very WARM (We went in Nov) and our group was visited by at least 8 sharks! Water was blue and clear. I personally did "chum" the waters after the cage dive, but I'd do it again in a heartbeat. We saw dolphins as well on the way out! Great job north shore shark adventure!
