Waipio Valley can cross the country and see the beautiful scenery of the valley. A picnic at the seaside is just fantastic. At the entrance of the valley, there is a viewing platform overlooking the whole valley. But to explore deep into the valley, you have to hike or have a four-wheel drive. We are the latter. Before entering the valley, the staff will check whether your vehicle has mounted 4WL (low-speed 4WL) and confirm that you can understand English. They are worried that we will rush into the valley and meet Kill people... Well, it turns out that we can do this off-road. Remind you that 4WL is suitable for cross-country, climbing, descending steep slopes, getting rid of difficulties, and can not be used for a long time! _________ Must be mounted in 1st gear to start, not more than 2nd gear in the whole journey! __________ If the oil lamp is on, it means that the oil overheating is caused by long climbing, because the car rental company will not use very good oil for the vehicle. At this time, you can put out the fire, let the vehicle rest, not too panic, if the water temperature is normal, the oil level is normal, you can continue to drive.
