Hi, my husband and I are staying in Princeville during our week in Kauai in January. We are planning to do a Napali boat tour out of Poipu if the conditions allow, which ends at about 2:30pm, and then picking up dinner take-out and heading up Waimea Canyon from Poipu around 3:30pm, and then we can watch the sunset and have a picnic at Kalalau lookout. Is this a good plan? I've heard that you should go early for Waimea but thought it would be nice to head to Waimea after our boat tour since we'll already be halfway there in Poipu and not have to drive all the way from Princeville. Thoughts? Thanks!
