A dive I will never forget ❤️🐠🐢🐋🐠 - Two amazing shore dives with an amazing and knowledgeable guide! Easy entry from the shore, a great beach park for surface interval time. While on the dive, we saw tonnes of fish, beautiful and healthy coral, all while hearing the singing of the nearby humpback whales! Who knew you could dive with a whale soundtrack?!?! This is a dive I will never forget. Thank you, Michael and Extended Horizons!

Gorgeous and Fun - Gorgeous dive sites, and the small group size made it easy to see what our knowledgable guides showed us. We not only saw an amazing breadth of sea creatures, but we could also observe and learn about their behavior, such as watching a Jack fish and an eel work together to snag a meal. I've been to some of the Lanai sites more than once, and I've had a spectacular dive every time.

Fantastic Dives - Victoria and Gabby were fantastic. Their knowledge of aquatic life and interest in sharing through group conversation with all divers on the boat were much appreciated. We liked the slow pace of the dive and the four divers to one divemaster ratio.

Best diving in Maui - Amazing crew very knowledgeable about marine life. Hands down the best diving experience you could have in Maui. I would highly recommend this charter. This is a small group 8 divers broken in to 2 groups of 4. If you want a good person dive experience this is were you should go.

Best Dive Experience So Far! - Captain Victoria and Divemasters Gabby and Rachel were amazing! Small group diving is where it’s AT!! They took care of everything my husband and I needed. The dive was relaxed and easy. The boat was well maintained. It was our best dive experience EVER (dives #43 & 44 for us). They were professional, courteous, and very well-educated about the marine life. We’ll definitely be diving with Extended Horizons again when we return again with our kids.

Excellent diving adventure! - This was a fantastic adventure! Captain Victoria and Gabi were the best - informative, attentive, patient, and clearly passionate about what they do. I went with my dad and my husband and we all thought it was one of the best dives we have ever been on. Gabi knows so much and takes time to show you all the little details - and even though she has done this a thousand times, she still got so excited! We loved it!! Diving in Hawaii is always beautiful, but it makes it even more enjoyable to go with an amazing dive group.

Great crew! - My son and I had a great time diving off Lana'i. The crew at Extended Horizons were friendly and professional, as well as educational. Loved how they had writing boards to describe what we were seeing during the dive and had a debrief after each dive to go over details of wildlife we had seen. Highly recommend!

Lanai Cathedrals - This outfit is the best of the best. Extremely professional. Dive Masters Victoria and Rachel were great as was Captain Chad. What an amazing experience! Lanai Cathedrals is a must for any experienced diver. 100 foot visibility, minimum surge. Beautiful day.

Best dive outfit - Extended Horizons continues to be the group we measure all other dive groups by. Their emphasis on sustainability, safety, service and local knowledge is truly exemplary. Captain Victoria, Gabby and Rachel made this incredible trip smooth and easy. This was our fourth time out on this unique adventure and it is totally worth going again.
