TLDR; Highest possible recommendation for this tour. Get in on this if you like having fun and snorkelling with turtles, dolphins, and fish.
This tour was suggested to us by Adam from the local Snorkel Bob's shop. He mentioned that he had been on a ton of tours and would suggest this one without any hesitation. We booked with him on the same day and it did not disappoint.
The crew for EO Wai'anae is amazingly friendly, knowledgable, and engaging. There wasn't a dull moment throughout the tour, even the drive from Waikiki to Wai'anae was entertaining.
The actual boat tour allowed us to get up close and personal with a number of sea turtles, spinner dolphins, and fish. We were able to get a lot of good video footage and pictures as Keola and his brother lead us to the best spots to encounter them. After we were all snorkeler out, we capped off the excursion with some tasty burgers and relaxed with stand up paddle boards and kayaks.
