My wife and I are experienced and advanced divers. We were spent a few days on Kauai before heading to the Big Island. The Kauai diving overall was enjoyable...unique from other places we've been diving. We found Koloa Landing easy enough from the map and directions from the folks at Seasport Divers where we rented tanks/weights. Parking was easy with many spots in the gravel parking lot/drive available. A couple other divers with their instructor were going in when we arrived. The surf was mild but the entry/exit is on an old boat ramp that encounters surge as the water funnels into shore. Timing the entry and exit is helpful. My wife had some trouble with the surge as she exited the water. The rock reef is in a horseshoe shape with lots of sand and a few rocks in the middle. We spotted a large turtle hiding behind one of the boulders. Overall sea life was ok but the surge and time of year probably played a factor. The south side of Kauai dives made me think of an ancient construction site with lots of giant boulders and pieces of the Earth's foundation scattered about. Overall a good dive, fairly easy to self-guide and a pretty spot for a surface interval.
