In between the hiking and flying, we went on a boat trip along the Napali coast, and also drove along the Waimea Canyon drive. The boat ride was not bad, but it was probably our least favourite way (out of hiking, flying, and boating) to see the Napali coast. The drive along Waimea Canyon Road was quite good, and there were good views of the canyon, as well as the waterfalls along the way. Unfortunately Kalalau valley overlook was clouded in and we couldn't see into the valley from up high.
