1. Kona Snorkel Trips

Kona Snorkel Trips has firmly established itself as the benchmark for snorkeling excursions in Hawaii, earning its title as the state's highest-rated and most-reviewed snorkel company.

This isn't just another tour operator; it's a premium, well-rounded choice for anyone seeking one of the best big island snorkeling tours.

The platform specializes in two of the Big Island's most iconic underwater adventures: the world-famous Manta Ray Night Snorkel and the historic Captain Cook Snorkeling Tour in the pristine Kealakekua Bay. What truly sets Kona Snorkel Trips apart is its unwavering commitment to both guest experience and ecological preservation. Their knowledgeable guides are all lifeguard-certified, providing expert instruction and fascinating insights that make the tours accessible and enjoyable for everyone, from nervous first-timers to seasoned snorkelers.

Key Strengths & Features

One of the most significant differentiators is the company's proactive approach to protecting marine life.

This dedication is a core part of their identity and a major reason they are a top choice for environmentally conscious travelers.

Expert Insight: The crew at Kona Snorkel Trips is frequently praised for going above and beyond. It's common for them to extend tour times if the manta rays are late to the party, ensuring guests get the full, magical experience they came for.

The user experience, from booking on their clear website to the tour itself, is seamless and supportive. They offer thoughtful extras like flexible gift cards without expiration dates, making them a great option for planning future trips or giving a memorable gift.

2. Hawaii Oceanic

For travelers seeking a more intimate and eco-conscious way to explore Kona's underwater world, Hawaii Oceanic stands out. This company prioritizes small-group experiences, capping their tours at just 12 passengers.
