  • Spend 5 days snorkeling alongside humpback whale mother-calf pairs in Vava’u, Tonga.
  • Spend 5 days exploring the 190-km of shallow coral reefs in Beqa Lagoon, Fiji, and support local conservation efforts.
  • Improve your fish ID skills and participate in coral restoration efforts.

Explore two of the best ocean destinations in the South Pacific on this one-of-a-kind itinerary. This two-week snorkeling odyssey will have you swimming with humpback whale mother and calf pairs in the blue waters of Tonga and then plying the vibrant, shallow water coral reefs of Fiji’s Beqa Lagoon. You will have ample opportunity in both countries to also explore the rich cultural heritage that each location has to offer, and your participation will directly benefit our conservation partners in both Tonga and Fiji.

During our stay in Fiji you will also have the unique opportunity to go out in the field with researchers from the Beqa Lagoon Initiative and learn about the work they are doing with local communities to restore mangroves and reduce marine plastic pollution. In the evenings the researchers will offer lectures on fish ID techniques and coral reef ecology. Flights between the destinations (and the U.S.) are easily arranged on Fiji Airways.

A detailed itinerary is available upon request. Please contact us.

Day 1: Arrive in Vava'u
Fly to Vava'u, Tonga (crossing the International Date Line), transfer to hotel.

Days 2–7: Whale Watching and Snorkeling
We will spend 5 days whale watching and reef snorkeling on boat- and shore-based outings. Typically we will head out at 9:00 am and return around 3:00 pm. We should be able to observe a variety of whale behaviors, from mother and calf interactions to the sometimes combative behavior of mature bulls. Humpback whales are the most acrobatic whale species, and will often perform spectacular displays of breaching, lob-tailing, spy-hopping, and fin-slapping. During times when we are not whale watching, we will have plenty of opportunities to snorkel along the nearby reefs. The sheltered waters of Vava’u offer a variety of snorkeling sites. Soft coral walls, large sea fans and an abundance of tropical fish and colorful invertebrates are found in these clear, warm waters. Set against the lush tropical coastline, we will also search for birds such as brown boobies, noddy terns, great frigate birds, and herons.

Day 8: Vava'u, Tonga - Nadi, Fiji - Beqa Island
Today we will say goodbye to Tonga and board a short flight to Nadi, Fiji (note: although this flight is not included in the trip cost, it can be easily arranged on Fiji Airways, and we will assist you in making your flight arrangements). Once in Fiji, we will take a boat ride to idyllic Beqa Island and check in to our hotel.

Days 9–13: Snorkeling Beqa Lagoon
We will have 5 full days to snorkel in the beautiful reefs surrounding Beqa Island. Just a short boat ride from the resort in the tranquil, crystal clear water is an incredible diversity of marine life, chock-full of soft corals, sea fans, garden eels, orangutan crabs, rays, bull sharks, tiger sharks, and various fish species. Each day, after breakfast, we will be picked up and head out on the water to go to multiple snorkeling sites. We will then take a short break to eat a packed lunch before going to more sites. We will go back to the resort mid-afternoon and have the rest of the afternoon to relax on the beach under the palm trees. Following dinner, your naturalist may give a presentation about the coral reef ecosystems and the global issues that impact them. There will also be opportunities to enjoy Meke, a traditional Fijian song and dance, while we drink kava out of coconut cups.
