Finally a port where there is enough time to do everything! The big attraction is the famous Waimea Canyon, similar to the Grand Canyon. It's a mile wide and 3600 feet deep, and has amazing colors. It's about a 40 minute drive from the ship to the first main lookout, with lesser lookouts before that. Regarding weather, the rule of thumb is that if you have bad weather when you reach the first main lookout, there is no point in driving another half hour to see the other lookouts further down the ridge road, it will not get any better. But if you have good weather, drive further down the canyon to the Puu Hinahina lookout, and then the Kalalau lookout, and Puu o Kila lookout at the end of the road. Then you can drive back on hwy 50 past the ship to the Wailua Falls up hwy 583, and Opaekaa Falls up 580, which feed the Wailua River. Then go back to hwy 56, turn back south on 56 for a few hundred feet, and turn right into the Fern Grotto tours place, I forget the name. There are other smaller vendors selling grotto tours, but the main one has a big parking lot, restaurant, etc. Tours are $15 and last 1.5 hours. The ship price is $45. The tour goes up the Wailua river, lots of great scenery, to a fern grotto where the locals put on a bit of a show. Then you can drive back to hwy 56 and
