Why it matters
Why Hon Mun and the Bay Islands is worth your time
The bay's coral and fish are why Nha Trang became a diving centre, and the marine protected area is part of an effort to conserve them. Seeing the reef is one of the better reasons to come to the town in the dry season.
It also changes the character of a trip. A day on the water complements the museum and temple days, and gives children a break from walking. Picking a good operator matters for safety and for the quality of the experience.

How to experience it
Island tours leave from the waterfront and visit a group of islands in the bay; Wikipedia names Hon Mun, Hon Tam and Hon Tre among them, and describes Hon Mun's marine protected area as one of the first four in Vietnam. Typical tours stop for snorkelling, swimming and lunch. Book the day before, ask what is included and check the weather.
Wikivoyage says there are around two dozen dive shops in town, with PADI open-water courses from around US$250; confirm current prices. Beginners can snorkel in calm water, but check that your insurance covers it. Wikivoyage also mentions Hon Tam mud baths among the day trips.
Take sun protection, a hat and a light cover-up. Vegetarian lunches are not guaranteed on group tours; request a meal in advance or carry snacks. If you get seasick, sit in the middle of the boat and choose the calmer months.
