When we had trouble renting a car or finding a snorkel adventure I saw the Custom Tour van when I was picking up some guests. I called and scheduled a tour for snorkeling and sightseeing. Unfortunately, when we got in the van Carey (owner and operator) informed us that due to the heavy rains the week before that water where he would take us was murky and brown. We then proceeded to take the tour from Honolulu around to the North Shore and back. He stopped for photos at the best places. He has a good knowledge of the Island and it's plants, trees, birds, etc. He took us to the Leonard's Bakery food truck and Fumi's for lunch. We stopped at several beaches, he pointed out waterfalls. He talked about movies that had been filmed on Oahu and the locations of various scenes. This is NOT a movie tour, but interesting facts. He did take us to a beach he knows typically has Turtles. One of my granddaughters was excited to be able to get in the water even if it wasn't snorkeling. Much to our surprise there was a turtle on the beach and in the water she saw several other Turtles. The water was shallow. It was low tide so she and my son had no problem walking out to see the Turtles and get some pictures, however the water was cloudy so the pictures weren't very good. By this time everyone was ready to head back to the hotel. They were disappointed the driver wouldn't let them eat shaved ice in his van, but were anxious to get back and did want to take time to eat it at the coffee and chocolate stop. The tour lasts up to 8 hours. He will take you where you want to go , but would recommend you ask him to take you to places where your full day would be spend at one location such as the Polynesian Cultural Center. For something like that a car rental would be less expensive. This 8 hour tour cost $550 for 5 people. Call for prices for your tour.
