The Cham Islands, or Cu Lao Cham, are a small group of granite islands about an hour or so by boat off the Hoi An coast, protected as a biosphere reserve. Day trips leave from the coast near Hoi An and Da Nang, stop at a beach and a reef for snorkelling, and return in the afternoon. The product we link to is a private snorkelling and beach trip from Hoi An, about six hours, with a rating of 4.0 from fourteen reviews on the tour page. It is a quieter, more flexible format than the large group boats, aimed at people who want the water rather than the sightseeing. Expect clear water over the reef on calm days, a simple beach lunch or snack setup depending on the operator, and a relaxed pace.
The most important fact is the season. The tour page states that boats typically only run from March to August, and that outside those months the sea can be rough and boats may not make the trip. This guide was written on 7 November 2026, in central Vietnam's wet season, so the honest advice is to treat this as a spring and summer activity and not plan around it now.
If you are in Hoi An in November, expect operators to cancel or to refuse bookings, and do not pay for an island day you cannot be sure will sail. If you are travelling in the dry months, book a morning departure because the sea is usually calmer.
What a day looks like
You are collected from your hotel and driven to the departure point, board a speedboat or wooden boat for the crossing, then spend time snorkelling at a reef and relaxing on a beach. Gear is normally provided, but confirm that fins and a life jacket are included and fit properly.
Private tours charge by group rather than per head, which is better value for a family or a group of friends than for a solo traveller. Bring a rash vest or sun shirt, reef-safe sun cream, a hat, a waterproof phone pouch and small cash for drinks and tips.
Things to know
The crossing can be bumpy even in good season, and people prone to seasickness should take medication in advance. The reef is modest compared with famous diving islands, so go for the setting, the swim and the day on a boat rather than for a world-class dive.
Hoi An and Da Nang operators run many near-identical trips, and the practical differences are group size, boat type, lunch and how long you actually spend in the water. Read the inclusions on the page, check cancellation terms and keep a flexible date in case of weather.
