Everything written about Seasport & their staff noted in the other reviews is true. They are very knowledgeable and know how to make sure everyone has a good safe dive. I went on 2 trips, one to Niihau (3 tanks) and one local (2 tanks). Niihau is a good dive site, not great, the run over is about 2 hours and about 2 1/2 back. So it's a full day with a lot of boat time sitting around. It's not uncommon for the return trip to be on the rough side. The local dives are just as good and the one to tunnel beach is definitely better. Run time on the boat is 10-15 minutes, dive is shallower, just as much coral and masses of turtles.
