What you'll see on a Cham Islands day trip
The Cham Islands (Cu Lao Cham) are a cluster of eight small islands off the Hoi An coast, protected as a UNESCO Biosphere Reserve since 2009. Most day tours visit only one — Hon Lao, the largest — and follow the same script:
- Hotel pick-up in Hoi An around 7.30am, then a 20-minute drive to Cua Dai or Cam Thanh pier.
- Boat crossing — 25 minutes on a speedboat, 90 minutes on a traditional wooden boat.
- Snorkel stop 1 at a shallow reef off Hon Dai or Hon Mo. 30–40 minutes in the water with basic mask and snorkel.
- Bai Lang village walk — a 45-minute stroll past the fish market, Hai Tang Pagoda, and the 200-year-old ancient well.
- Seafood lunch on Bai Chong or Bai Ong beach — usually grilled mackerel, squid, morning glory, and rice.
- Beach time and snorkel stop 2 — another hour of swimming or lounging before the boat back.
Getting there from Hoi An
The day starts at one of two piers on the Hoi An side, and which one you use depends on your tour.
- Cua Dai pier is the main speedboat departure point, about a 15–20-minute drive from the Old Town. Most group tours include this transfer in the price and collect you from your hotel around 7:30am.
- Cam Thanh / Bach Dang pier handles the slower wooden boats and the public passenger ferry.
The crossing itself is the real variable. A speedboat covers the 18 km in around 25 minutes but slams hard over chop on a windy morning — if you're prone to seasickness, take a tablet before boarding rather than mid-crossing. A wooden boat is far gentler but takes roughly 90 minutes each way, eating three hours of your day. The public ferry from Bach Dang is the cheapest crossing at around 150,000 VND return, but it runs on the islanders' schedule (typically a morning departure and an early-afternoon return), leaves no margin for snorkel stops, and is uncovered, so it bakes in midday sun.
If you're staying in Da Nang rather than Hoi An, add 30–40 minutes of driving to reach Cua Dai; few operators include Da Nang pick-up, so most travellers join from a Hoi An base.
How to book
- Group speedboat tour — the default. Book at any Hoi An travel agent or online a day ahead for 600,000–900,000 VND ($25–38). You'll share the boat with 20–30 others.
- Group wooden-boat tour — cheaper at 450,000–600,000 VND, but you lose two hours to the crossing. Only worth it if you specifically want the slow-boat experience.
- Private charter — $180–250 for a speedboat seating up to 8. The only way to skip the Bai Chong lunch scrum.
- Self-guided — take the public passenger ferry from Bach Dang pier (departs 8am, returns 11.30am from the islands) for 150,000 VND return. Doable but tight, and you'll miss the snorkel stops.
When to go
The sea around the Chams is only reliably calm between April and September. May, June, and July have the clearest water and lowest rainfall. August and September can be hot but still swimmable. October through March the islands are effectively closed — the marine park authority suspends tourist boats when swells exceed 2 metres, which happens most weeks.
On shoulder-season days (early April, late September) ask your tour operator at 6am whether the trip is confirmed. Cancellations are common and refunds are usually quick.
Typical cost breakdown
- Speedboat group tour with lunch: 600,000–1,050,000 VND ($25–45)
- Marine park entrance fee: 70,000 VND (usually included)
- Snorkel gear rental: 50,000 VND if not included
- Optional jet ski or parasailing at Bai Ong: 400,000–600,000 VND
- Tips for boat crew: 50,000 VND is standard
Lunch portions on group tours are modest. If you're hungry, order extra grilled squid at the beach restaurant — it's charged separately at around 200,000 VND a plate.
Is a Cham Islands day trip worth it?
Worth it, with caveats. The boat ride itself is pleasant, the village is genuinely charming, and the seafood lunch is better than most beach-tour fare in Vietnam. But don't go expecting Phu Quoc or the Philippines — the snorkelling is mediocre, the main beach gets crowded by 11am, and anyone who's done island-hopping elsewhere in Southeast Asia will find it underwhelming.
Go if: you're in Hoi An for four-plus days and want a break from the Old Town, or you like boats and seafood more than coral. Skip if: you have limited time and haven't yet done My Son Sanctuary or a cooking class.
Who it's best for, and who should skip it
The Cham Islands reward travellers who treat the day as a boat-and-beach outing with a swim, rather than a serious dive trip. If you have several days in Hoi An, enjoy seafood and sea air, and want a contrast to the Old Town's lanterns and tailors, it lands well. Families generally enjoy it — the swimming is calm in summer and the village walk is short — though the speedboat crossing can be rough for very young children.
It's an easy skip if your visit is short, if you've already snorkelled somewhere like Phu Quoc, Nha Trang, or the Philippines, or if your trip falls outside the April–September window when the sea is reliably open. Serious snorkellers and divers in particular tend to leave disappointed: the reef is patchy and the day is built around the boat ride and lunch, not the underwater time.
Practical tips
- Bring reef-safe sunscreen and a rash vest. The marine park discourages heavy oil-based sunscreen, and you'll be in open sun on the boat and beach for hours.
- Pack motion-sickness tablets if you're at all prone — the speedboat is fast and bumpy on a windy morning.
- Carry small cash for the optional grilled squid (around 200,000 VND a plate), drinks, a beach-lounger fee, and a crew tip; card payment is unreliable on the islands.
- Take a dry bag. Spray on the speedboat reaches the seats, and there's no dry storage during snorkel stops.
- Confirm the trip the evening before in shoulder months — operators decide by sea conditions and a quick call saves a wasted 6am alarm.
Limitations
The Cham Islands day-trip operates only April to September — northern-monsoon swell makes the speedboat crossing genuinely unsafe October through March, and operators suspend trips for several days at a time even in shoulder months when wind picks up. Workaround: confirm operator status the day before; have a Hoi An cooking class or My Son sunrise tour as a backup plan if Cham is cancelled. The water-clarity peak is May to July; April and early September are the shoulder windows with smaller crowds.
The snorkelling at Bai Chong and Bai Xep can be crowded mid-day in peak summer — 40-60 swimmers per cove is common in July-August. Workaround: book an early-morning departure (7:30-8:00 a.m. boats reach the islands by 9:30 a.m. before the second wave); or book a private-charter or small-group tour ($60-90 per person) that targets less-visited coves. The Cham Islands' marine biodiversity is genuinely strong but the volume of standard-tour boats is the binding constraint on the snorkelling experience.
