Situated on the border between Brazil and Argentina, the falls are made up of 275 separate waterfalls which occupy an area 3 miles wide and 80 metres high, flanked by lush rainforest. There are national parks on both sides of the falls, with the Brazilian national park founded in 1939 and designated a UNESCO World Heritage Site in 1986.
The Brazilian side of the falls offer excellent panoramic views and are best visited in the morning when the light is better for photography. The Brazilian side is also best for sunset views. The most spectacular part of the falls, the Devil's Throat, is on the Argentine side, and some of the best rainforest trails are also on this side. A guided visit of the falls usually includes visits to the principal viewpoints on both sides of the falls, a zodiac trip upstream towards the falls, and a chance to hike some of the rainforest trails.
