The shock of Iguazu National Park is beyond expectation! Standing on the observation deck on the Brazilian side, 275 waterfalls pour down like the Milky Way, the roar of the "Devil's Throat" is deafening, and the mist and rainbows come to your face. The plank road on the Argentine side goes deep into the waterfalls. When you rush into the water curtain by boat, you will feel the wild power of nature when your body is soaked by the majestic water. The howler monkeys and blue-violet macaws shuttle through the tropical rainforest, and the waterfalls together form a three-dimensional ecological picture. It is recommended to reserve two days, take a helicopter to overlook the horseshoe-shaped panoramic view in the morning, and watch the sound and light show on the Brazilian side in the evening, so that your vision and hearing are immersed in this earth-class wonder.
