Extended Horizons dives the Lana’i coastline with a maximum of 10 divers and two dive guides, so there are never more than 5 divers per guide. Lanai is famous for its Cathedral dives, swim-throughs, archways, and lava structures. We dive both First and Second Cathedral on a regular basis. Many divers agree that Lanai has the greatest diversity and marine life density of any diving location in Hawaii.
Our tour is guided by certified naturalists and marine biologists. We go SLOW so you see more.
This is a two tank boat trip. We do two dives, at two locations. There are over 40 dive sites to choose from, ranging from beautiful coral reefs to unique lava tubes.
Between dives we serve a light lunch and bottled water. Towels aren't provided.
