After visiting the Seven Holy Pools, you can return. My advice for the entire Hana road: 1. The original Twin Falls or the Waikamoi natural trail near the 9 mile signpost does not need to spend too much time, because there are many waterfalls or rainforest walks, etc., there is no need to waste time here. But the pineapple smoothie at the entrance of Twin Falls tastes good! 2. There are several attractions that are more recommended, Keanae near the 17-mile signpost; Waianapanapa state park; red sand beach in Hana Town; Seven Holy Pools, Oheo Canyon 3, Hana Road is very narrow, many sections of the road only allow a car to pass (note the road marking), always in the mountains, the speed can not be too fast, drive carefully 4, when we return from the seven Holy Pool to Paia took two and a half hours, about four o'clock 45 to start returning, The sun set at 5:45, and it was dark at 6 o'clock. It was very difficult to open the mountain road after dark. There were no street lights abroad. The mountain road was more dead, and the road was narrow. It is recommended to calculate the sun setting time (generally you can ask the hotel front desk), 3 hours in advance must return 5, Hana road has a lot of attractions, many of us have omitted, and there is no sea. If there is time, you can actually spend a night in Hana Town, so there is enough time, you can stay a little longer on the black beach or the red beach, take a swim or something.
