We called them up from a cafe' in Hanoi without knowing anything about them.
They came to pick us up 2 hours later with a fantastic driver and very clean bus with wifi. The driver is vey nice man who "speaks" some french, some English etc.
The guys on the way to Cat ba were attentive, very professional, they collected payment on the bus.
The following day we decided to go on the boat tour with them.
FANTASTIC service, not one of those floating music box, fresh food cooked for lunch on board....Kayaking around with our guide was funny and he knows many things about the place. He also has "British humor" which makes him a very picturesque figure. Staff on the boat very nice as well. the return was smooth, cheap, professional and Swiss punctuality!

I would highly recommend the Cat Ba Express 1 day boat tour, Ngoc is a brilliant tour guide and is so knowledgable. You get to see Ha long Bay and other bays the way they used to look before all the tourists (i know us...) arrived. You're taken off the beaten track and the kayaking was incredible. Fully worth the low cost, would definitely do again! Can't think Ngoc, Son and all of the team onboard for a great day. Thx!!

We went to Cat Ba and back to Hanoi with this company, the bus was comfortable and the service was good. The prices for tickets were good too, the way lasts about 3 hours and half. Highly recommended!

I have to start like this. The tour was amazing, can’t find better word that would describe it! Our guide, Ngoc, was a lovely guy who took us to the places where either a few tourists or even no turists were and we didn’t see the same thing twice. We visited a fishing farm, then did about 1,5 hour of kayaking in gorgeous places and got through 3 or 4 wonderful caves. Later on we had a great lunch (a fish, a rice, a chicken, a veggie noodles and more that I can’t remember). At last we swam in a lovely bay.
Also everything came with deep explanation and he knows what he’s talking about. It felt like he lived there for a while.
This tour was over our expectation and for a very fair price of 22$ I think.
Big thanks to Ngoc and all my respect for his knowledge and friendly attitude!!
And he loved our companion on travel @llamamaricarmen
