The Best Liveaboard Trips in the South Pacific

With an abundance of hard and soft corals, wildlife like whales, mantas, sharks, sea turtles, and friendly locals who happily welcome visitors to their beach-fringed islands, there’s no reason no to go on a liveaboard trip in the South Pacific. In this guide, we’ll cover the best liveaboard trips no matter what type of diving you’re into.

Why dive in the South Pacific?

Encompassing tropical continents, archipelagos and island countries below the equator, the South Pacific is the epitome of a flourishing display of life’s diversity as immense natural bounty can be both seen on land and underwater. For scuba divers, the South Pacific is a gigantic playground courtesy of miles and miles of coastline and offshore islands that house thousands of dive sites. And it’s not just about the number of dive sites, but it is also about quality where the South Pacific holds world-class dive sites considered to be some of the best in the world.

Since it is located in the tropics, expect crystal clear waters where visibility can reach over 30 meters (98 feet) and warm water temperature ranging from 28 to 33 C (82 to 91 F). However, take note that most of the pristine sites are located far away from each other while some of them are situated offshore. To maximize your South Pacific diving adventures, we highly suggest that you book with a liveaboard dive trip as these custom-built vessels will take you to the remotest sites that often holds the most abundant marine life.
