Great way to spend the day whilst in Hoi An - peace and quiet away from Hoi An - Nice staff, good fun. Lunch on Cham Island was very nice. Walking on sea floor was a great experience - would recommend it. Snorkelling at a few different places was good. Good value, great with kids 12-16 yr old

Must do under walking - It was amazing experience definitely do the underwater walk Lovely lunch many food options And snorkel in 2 locations Guides spoke good English

Well worth it - Well worth it, especially if you cannot scuba dive. We had about an hour of snorkeling as well as 15/20 minutes of sea trekking. There were some divers who assisted. The meal provided was very good. Well worth it.

Worth it for the Underwater Walk Alone - We really enjoyed the tour! The corals out in Cham Islands were better than we expected them to be and the underwater walk was loads of fun! We had a nice lunch on a beautiful beach as well.

A must do - Fantastic trip. Bubble hats were fantastic and a definite must. Good on beach was lovely. Highly recommend

Nice experience and good family activity - not the best value for money though - Good experience and fun family day. It could have been shorter and we could have been back right after lunch - some 2 hours shorter -, but I guess it is a trick for those who factor in the duration of activities when comparing tours.

Speed boat staff Could have been better - Sea walking was great. The main guide was nice as well. The organisation was good. We booked a night before so we’re pleasantly surprised that everything went smoothly. The only negative was the speedboat staff. They have provided with faulty snorkelling device so the water keep coming in. When I told them, they told me to tighten it up, but it didn’t help. I asked them if I can come back to exchange for a different one, but they were ignoring me. I was waiting in the sea near boat to get back in, but as the boat anchored near stones and waves were quite strong, I cut my leg. Luckily one of the passenger help me up. Tried another snorkelling device and was absolutely fine, but they didn’t want to acknowledge the faulty one and just throw in back in the basket (so I guess no sanitisation?).

Well organized but nothing special to see - Logistics were organized very well. Pickup was on time, they had towels and locker on boat, and the diving crew was efficient. However, water was very unclear during the sea walking so we didn't really see anything (I don't know how it usually is), and the snorkeling spot wasn't great. Lunch was very basic too.

Bad organization's and communication - The guide was good, food was also good. But the tour operator contacted us the evening before the trip that the underwater walking was cancelled and transfer would be with a speed boat instead of a traditional boat. He said the walk would be cancelled because of the weather but it was obviously a lie, because the weather was good, there were simply not enough people who signed up for this. And the transfer in the speed boat was a mess, we were put together with another tour and the boat was very full which also had an impact on the snorkeling which was also rather crowded. In the end more time on the beach would have been welcomed by all participants. Snorkeling was OK, not many colors left but some fish and sea stars.

Disorganised business, pretty disappointing. - Big disappointment, first of all we booked the walk underwater activity, which later we were informed by email wouldn't be able to do due to low visibility on the water, (when we got to the boat the guide actually said the equipment was broken, so we've been lied to). And we only got refunded 15$ for not having the main attraction of our experience. We also booked a transfer from the hotel, and they have forgotten about it. I had to call early in the morning to get it, and the driver went to the wrong hotel. We only got allowed to snorkel in two locations for a very limited time, after we got to a beach where we had to stay for three hours "free time" and had lunch. On the return to the mainland one of the engines of the speed boat wasn't working, and the boat crew was trying tirelessly putting it back on but not successfully. And they said they were going to proceed with just one engine on the open sea! The whole group refused, as it didn't seem to be safe. So we stopped at the harbour and stayed there for a half hour or until another boat showed up to pick us up. The guide wasn't really a guide he was more just accompanying us as he didn't give us any information about the islands or sea life, or curiosities . Very disappointed with the overall experience.
