Is there water?
Whether there is a river here on your dates, and what kind of water it is.
Rain-fed and flashy; monsoon spikes; upstream diversion/Nam Ngum basin influence. Confirm.
Year-round; wet-season floods can close tubing/kayak for safety
Dry season Nov-Apr (safest, clearest); wet season Jun-Oct higher/faster and can be dangerous
Warm tropical; cooler/faster in wet season
Flash-flood risk in wet season; drowning incidents historically tied to alcohol + high water
Grade & who can come
A river changes grade with its level. These grades describe a normal flow - in flood the same run is harder, and often a different run entirely. Check the gauge before you commit.
Grade I-II
Kayak; river tubing; SUP (secondary)
Kayak vs tube vs SUP; combine with cave/lagoon stops; beginner lessons offered
Very beginner/family-friendly (dry season)
The run
No defined technical crux; wet-season high water and cold fast current is the main challenge. Confirm.
