Snorkeling: A Beginner-Friendly Paradise

Snorkeling is undoubtedly the easiest and most accessible way to get a glimpse of Hawaii’s underwater beauty.

Many beaches across the islands offer excellent snorkeling opportunities, but some stand out above the rest.

Tip: Consider taking a SUP lesson if you’re a beginner. Beginners should start in calm waters and with a wider board for better balance.

Whale Watching

During the winter months (typically November to May), humpback whales migrate to the Hawaiian Islands to breed and give birth. Whale watching tours are a popular activity, offering the chance to see these magnificent creatures up close. Several tour operators offer whale watching tours from various harbors on the islands, but Maui is particularly popular.

Recommendation: Pacific Whale Foundation offers whale watching tours and contributes to marine research and conservation efforts.

Protecting Hawaii’s Underwater World: Responsible Tourism

Support Sustainable Tourism Practices: Choose tour operators who are committed to environmental protection and responsible tourism practices.
