Kai Bear is the boat my wife and I and two other couples went out of Nawiliwili harbor. I remember the crew talking about how good the summer months are for marlin. So I’d check out how the fishing should be in March. We went out in Sept. a couple of years ago and 1 blue marlin was caught along with 2 mahi mahi. Fishing began less than ½ Hr. out of the harbor and looking at the Island we could see where the opening shot of Jurassic park was taken.
On the way back we trolled almost to the harbor break water. I’d do it again if we were there during the prime Marlin fishing time.

Other attractions on Kauai they have a lot of scenic things like their grand canyon, kayaks on the river, trout fishing and peacock bass (ask the guides), golf courses, and of course all the beaches around the Island.
