Snorkeled here a few years back - great site for something so close into shore. The resorts were fully built at that time (referencing earlier review) and didn't seem to have a negative impact on the reef life. Very few snorkelers. Best spots are a little farther north from the park in front of the Westin property before you get to the Honua Kai condos. There was an empty lot there too, which was nice and quiet and less people at the time. Great spot for beginners - will take my wife there for some of her first times on a reef next week.
