From the form to the first kilometre

• Dates, or a month and how flexible it is. In the flood season a shift of a few days can mean a weekday at Tra Su instead of a crowded Saturday.
• Numbers: how many riding, how many in the vehicle.
• Heights of each rider, for bike sizing.
• Recent riding or walking: a sentence each is enough. 'Rides 30 km at weekends' tells us more than 'fit'.
• Anything that limits the day: knees on descents, heat sensitivity, diet, a fear of narrow bridges.

If you are unsure which grade suits you, read grading and fitness first; it has a short self-check.

Each quote is checked against three calendars before we send it. The tide and flood calendar: high tides flood riverside streets in Can Tho and Vinh Long in October and November, and the 2025 authorities advised limiting travel at high tide in the early morning and late afternoon. The lunar calendar: the Sam Mountain festival runs from the 23rd to the 27th day of the 4th lunar month. And the park calendar: opening hours and ticket prices at Tra Su, Tram Chim, U Minh Ha and the cape, which we re-read for your dates.

The guide may change the order of a day, shorten a ride, or move a climb for weather or water. That is part of the trip, not a failure of it. If a whole activity cannot run, for example the Cam Mountain climb in a storm, we replace it with the nearest equivalent the same day (the cable car up and a walk on the summit area) and tell you what changed in cost, if anything.

If you need to change dates after confirming, tell us as early as you can. What can be moved without cost depends on the rooms and boats already held; the written quote says which items are refundable and which are not.
