The Cathedrals were amazing! We saw a whitetip shark, eels, a giant puffer, and lots of rare fish. Extended Horizons was extremely well organized, super nice, and knowledgeable about the reefs. This is a highly recommended trip.

I have over 100 dives and have seen many different types of underwater delights. The Lanai Diving Adventure was an excellent dive and highly recommended. So many tubes/caves/coral you will not be dissatisfied.

We arrived at the boat launch for the pre-trip briefing at 630a, then we returned from the 2 tank dive at 12p. 5.5-6 hours should be allocated. Have fun, it was great!
