Eleanor Roosevelt is supposed to have said "poor Niagara" on first seeing Iguazú. It's a good line and it misses the point. Each of these three is the best in the world at something different — and the right one depends far more on what kind of trip you want than on which is biggest.

Victoria Falls: for adventure, and for Africa
No other waterfall comes close for things to do. The bungee from the Victoria Falls Bridge, the gorge swing, grade-5 rafting in the Batoka Gorge, helicopter and microlight flights, and — for roughly five months of the year — Devil's Pool, a rock basin on the very lip of the falls where you can lean over the edge. Add a sunset cruise on the upper Zambezi, rhino tracking on foot and a day trip to Chobe in Botswana, and it is a week's trip rather than a stop.
The catch is timing. At peak flow in April the spray is so dense you may not see the bottom of the falls at all, and the rafting stops. At low water in October and November the Zambian side can shrink to bare rock. Most people who want both the spectacle and the activities aim for the shoulder months. Our season guide goes month by month.
Iguazú: for immersion
Iguazú is the one you walk through. Kilometres of catwalks on the Argentine side take you over, beside and under dozens of separate falls, through subtropical rainforest full of coatis, toucans and butterflies, to the edge of the Devil's Throat. The Brazilian side is the panorama — a single path with the whole horseshoe laid out in front of you. Boats run right into the spray at the base.
It rewards time: a full day on the Argentine side and half a day in Brazil is the minimum. Check before you go whether the Devil's Throat catwalk is open; flood damage has closed it before, and our Iguazú guide has the current status. Adventures here are gentler — boats, a helicopter from Brazil, a zipline in the jungle — but the setting is the wildest of the three.
Niagara: for ease
Niagara is the easiest great waterfall on earth to visit. It is 90 minutes' drive from Toronto, free to look at from either side, open all year and lit up at night. Water volume barely changes month to month — the two governments divert a share of the river for hydropower and guarantee a minimum flow over the falls — so there is no bad season for the falls themselves. What changes is what's open: the boats into the Horseshoe Basin, the zipline and most outdoor attractions run from roughly late April to early November.
It's also the most built-up, and the tourist strip is not the falls. Stay on the parkland side, do the boat, the Journey Behind the Falls and the Cave of the Winds, and take an evening in Niagara-on-the-Lake. The full guide covers both sides.
So which one?
- You want adrenaline, or a safari in the same trip: Victoria Falls.
- You want to be inside the scenery for a whole day, with wildlife: Iguazú.
- You have a weekend, children, limited mobility or a stopover in Toronto or New York: Niagara.
- You want the biggest single wall of water: Victoria Falls in March or April.
- You want the most photogenic: Iguazú, closely followed by Victoria in the shoulder season.
If you've done all three, the next tier up in sheer scale is Kaieteur in Guyana — a single 226-metre plunge with almost nobody there — and Angel Falls, the tallest on earth. See the tallest waterfalls and the widest for the rest.
