Is the Waterfall Open? How to Check Closures and Water Levels

A waterfall closes when the water or the weather says so, and the closures in this guide lasted from a day to a few weeks, not a season. The reliable check is to read the operator's or park's own news page for the date you travel, then compare the water figure it gives with any threshold it publishes. A tour listing, a blog post and this guide are all older than that page. We learned this on our own catalog. In an October 2026 audit we found a one-day Erawan closure and an expired Wadi Shab advisory written into descriptions as if they were standing conditions. Both had been true once. A closure is a dated event, and it needs a date to be useful. For the calendar side of the question, see our guide to when to visit waterfalls.

This page gives general information from the sources named on it, as we read them on the dates shown. It is not medical, legal or safety advice. Rules and conditions at a waterfall can change within hours: follow the signs, the park and your guide, and see a doctor or your public health authority for health questions.

We earn a commission when you book a tour through the links on this site, at no extra cost to you. It does not change what we write. How we are paid is explained in our Editorial Policy. If you are choosing between offers, how to read a waterfall tour listing explains what to look for in the cancellation terms, and guided tour or on your own covers the sites that sell their own tickets.

Start with whoever runs the place. Park and concessionaire pages post closures in news items, and some publish the water figure itself. For the river, national gauge networks and river authorities publish readings that you can compare with a long-term mean. The table lists what we found and read on October 27, 2026. Pages like these change format without notice, so treat the list as a map of where to look and not as a promise that the same links will work next year. Look first.

The Brazilian side of Iguazú is the most recent case we could read, and the concessionaire posts it in detail. Its protocol page, dated October 13, 2026, says the walkway is closed as a precaution when the flow exceeds 8.5 million liters per second and shows a tendency to rise, and that the walkway railings are removed when the flow is between 9 and 12 million with an upward trend. About reopening it says, in Portuguese: "A reabertura da passarela depende de a vazão atingir, no mínimo, 8,5 milhões de litros por segundo." In English: reopening depends on the flow reaching at least 8.5 million liters per second. The sentence is ambiguous and we do not resolve it. The page adds that reopening also needs an assessment by the technical team and the authorization of a specialist engineer.

Those numbers belong to the Brazilian concessionaire and to its walkway. The Argentine side is run by Argentina's national parks administration under its own rules, and we do not mix the two. Each operator sets its own line, and the lines differ.

Read the table twice. On October 19 the flow was below the 8.5 million line and the walkway was still closed. The October 13 page says reopening also needs a technical assessment and an engineer's authorization, and the October 19 post says only that reopening depends on river conditions and technical evaluation. The posts do not say which condition held it shut. On October 26 the flow was 11 times the mean the park quotes, and the park was still open. A closed walkway is not a closed waterfall. The park's pages in this period say the main trail and its viewpoints stayed open. Sources: the October 26 post, the October 15 post and the October 19 post. Our guide to which side of a border waterfall to choose covers what each bank offers.

Krka shows the other pattern, a closure that came from the river itself. On May 16, 2023 the water at Skradinski buk reached 254 centimeters, the highest since measuring began, and the park closed Skradinski buk and Roški slap and canceled all boat excursions. We cover the numbers in when does a waterfall have water. Our Krka tours page covers the visit in a normal year. Winter closures of paths behind falls, such as the ice at Seljalandsfoss, are in the guide to snowmelt, ice and frozen falls.

A closure has a date on both ends. If a page gives only one, ask the operator for the other.

Yes, and it is the commoner case. The Zambezi River Authority's bulletin said on October 26, 2026 that flows at its Victoria Falls station, Nana's Farm, were steadily decreasing and closed the period at 296 m³/s, down from 329 on October 13. The page lists the same date a year earlier as 223. It also gives the long-term mean annual flow as 1,100 m³/s. Do not set 296 against 1,100. The second figure is a mean over a whole year, and late October sits at the low end of the river's cycle. Compare a reading with the same date in other years, which the bulletin provides, or ask the operator what the falls look like in your month. Low is not closed. Our Victoria Falls tours page lists the offers from either bank.

At Rhine Falls the home page of the Rheinfall site carries a live discharge reading sourced from the Swiss Federal Office for the Environment, with a webcam beside it. When we opened it, it showed about 114 m³/s. It is the simplest example of the principle: the number, its source and a camera on the same page. For a river without a live panel, the USGS and Water Survey of Canada sites give station data for rivers in their countries, though not every waterfall has a gauge nearby, and the nearest gauge is not always on the same stream. The method page explains why we treat gauges and proxies differently.

Cancellation terms sit on each offer's page, and they differ by offer, so read them before the day and not at the gate. If a path closes but the tour still runs, ask what the operator offers instead. If the operator cancels, ask in what form the money comes back. Redevelopment is a different case again. Niagara Parks says Journey Behind the Falls will remain open while its restored tunnel (announced for spring 2027) and upgraded Rainbow Platform (spring 2028) are completed, so works at a site are not closures. Our Canadian side tours page lists the offers. Look at the terms. The principle in our listing guide applies at every site: the terms in front of you, on the date you buy.
