Hanoi isn’t just about bustling streets and historic temples—its proximity to stunning water-based adventures makes it a surprisingly good spot for snorkeling.

It’s an excellent choice if you want a mix of underwater adventure and relaxed island life. For those seeking a more exclusive experience, the Con Dao Night Turtle Watching And Coral Snorkeling Eco Tour offers a chance to see endangered turtles and explore mangroves. And if a quick day trip fits your schedule, the Hoi An: Cham Island Snorkeling Adventure & Seafood Lunch provides vibrant coral reefs and cultural sights in one go.
