The whole Bai Tu long tour itself was great and it was well organized from the start till the end!
Our tour operator Tran Lien did a real great job; always replied fast and helped us short hand and efficiently.
Our dschunk, the Dragon's Pearl, was a nice and small ship so it was a private atmosphere.
The crew was friendly and helped us in any way they could.
We did kayaking and have seen beautiful natural tunnels (which we passed) and had a georgeus lunch at the beach - the crew grilled fish on the wood-fire grill.
The best was the stunning landscape we experienced!
All in all it was a phantastic experience, though the weather was mediocre...
At least in our opinion an absolute must do in Vietnam!
(And take the 3d2n tour to Bai Tu Long, it's not that crowded then Halong bay...)
