While there’s absolutely nothing wrong with laying out a towel for a relaxing day at one of Phu Quoc’s many white-sand beaches, there’s a lot more to do in the turquoise waters as well. Active travelers might choose a full-day snorkeling trip, floating above colorful coral reefs teeming with tropical fish. You’ll also find some of Vietnam’s best scuba diving, with options for beginners and certified divers alike. And if you prefer to stay in the boat, spend the day fishing for mackerel or barracuda. Later, refuel with a street food dinner at a local night market.

If you can tear yourself away from the beach, Phu Quoc offers some excellent inland adventures. Get off the beaten tourist track with a day of kayaking on the Cua Can River, or head into the verdant jungle of Phu Quoc National Park for a hike. Families looking for a kid-approved day outdoors should snag tickets to Vinpearl Safari Park, for the chance to see Bengal tigers, lions, and other animals in a safari-like environment. After a day of activity, reward yourself with a chill evening at one of Phu Quoc’s toes-in-the-sand beach bars, many of which serve fresh-caught seafood.

Take a day to learn more about the people who call the island home (and the products that make it famous). A guided circle island tour is a good place to start—most itineraries include visits to a pepper plantation, fish sauce distillery, and pearl farm, so you can see what goes on behind the scenes of three big island industries. If you’re interested in Vietnamese cuisine, consider signing up for a cooking class with a local chef. Rest up in the afternoon to prepare for a unique evening activity—squid fishing. Venture into the water at sunset for an after-dark lesson in luring squid, followed by a barbecue dinner featuring your catch.
