I was lucky enough to live on Kauai from 1994 to 1999 and dove Koloa Landing no less than 40 times. It is a wonderful dive and is a must for anyone wanting to get in an inexpensive quality dive. The entry is a old boar ramp and rocks beyond; leave the fins off until you get in the water and go from there. There is an excellent reef to the right and a shore wall to the left; an anchor and chain are out about 150 yards. Many fish and reef creatures to be found. A great night dive can be had here, as well.
