Planning a field trip to the delta

Two days is the useful minimum for a class from Ho Chi Minh City: the delta's most instructive hours are early in the morning, so students need to sleep there. Can Tho is about 171 km away, roughly three to three and a half hours by coach on the expressways. Three or four days lets you add a second base — Chau Doc for the flood, the fish farms and the Cham, or Soc Trang for the Khmer — and to run briefings that build on each other. Beyond four days, students tire of the coach and the returns fall.

Boats are central to a delta trip, so this is usually the first question a school asks. Vietnamese rules require passengers on cross-river passenger boats to wear or hold a life jacket from leaving the pier until docking, and Can Tho's transport department has instructed that passengers at tourist piers wear life jackets and that boats must not exceed their passenger limits. On our trips everyone wears a life jacket for the whole time on the water, whatever the boat.

• Boats are chosen for the group's size, with the number of passengers below the boat's limit
• Students board and leave one at a time, with a teacher counting on the wharf and on board
• No standing on roofs or gunwales; no trailing hands in the water near propellers
• The boat crew and the guide can cancel or change a boat stop for weather; we replace it with a land stop on the same theme

For each stop we prepare a task sheet with four parts: observe (what to look at and sketch), measure or count (boats, trees, flood marks), source (one figure with its publisher and date), and ask (two or three questions for a farmer, trader or community member through the guide). Briefings at the start of each day set up the question; a closing session asks teams to argue a position with their evidence.
