Woke up early, able to do tai chi on the deck before breakfast. It was exhilarating and even spiritual. Took a boat to some amazing caves. A long drive back to Hanoi ... Checked out some stores in the Old Quarter, ate dinner in Little Hanoi, then took the overnight train to Sapa.

Left Hanoi at 8 a.m. and took a 4-hour drive to Halong Bay. Headed out in our boat. We docked near floating villages. We took a boat to view them, stopping at communal area that included a school. Robbie and I kayaked. There was a cooking demonstration, then dinner. Tomorrow we will see some grottos, then back up to Hanoi.
