Terms
The information on this site is general guidance. Flows and best months are long-term estimates, not a forecast and not a safety assessment. Rivers rise fast after rain, rocks near waterfalls are slippery, and paths may be closed.
Data is used under the licences listed on the data sources page.
Safety near water. Stay behind barriers and on marked paths, never swim above a waterfall or in its plunge pool unless it is a designated swimming spot, and check local warnings before you go. In an emergency in Europe, call 112.
Affiliate links. Some links on this site are affiliate links. If you book or buy through them we may earn a commission, at no extra cost to you. Which partners appear never depends on what the data says: the numbers are the same with or without them.
