This was my family's first dive experience since certification and I can definitely recommend Koloa Landing as an easy, gentle introduction dive for first-timers, esp. kids. The entry was easy (although a bit slippery), vis was good at ~30 ft, and lots of sea life: green sea turtles, moray and dragon eels, a nice moorish idol, etc. I wanted our first dive to be exciting for our kids (ages 12 & 14) and I got exactly that (the crowded conditions not withstanding). We're all hooked on diving now!
