Compliments to the crew

Whales I’ll never forget

My heart beat like a hummingbird, when more whales than I can count calmly passed our boat a few feet from us . The crew were friendly, safety conscious, and served up the best drinks and food on our trip to a sky blue water snorkeling spot. MAUI was an incredible trip, and this was definitely a highlight.

Do yourself a favor and go with the best!

Do you know that feeling when the world disappears and real relaxation sets in? That's the best way I can describe our tour with Alii Nui. Family of four, two kids, ages 10 and 11. It's nice to spoil yourself when you're on vacation, and we opted for the "premium" experience for our snorkel tour and went ahead and booked with Alii Nui; not really sure what to expect or what sets this company apart. Having done other snorkel tours before all over the world, I can say with confidence this is an exceptional experience.

Incredible Experience

We did the snorkel cruise with Cap'n Sam--it was unforgettable. The crew was fun and professional, and the boat was spacious and clean. We dove on beautiful reefs, got mugged by whales, ate terrific food, and met some wonderful people. We're already dreaming about coming back.
