Amacayacu National Natural Park is a national park located along the Amazon River in the Amazonas Department in the south of Colombia. The park was created in 1975. The word "Amacayacu" means "River of the Hamocs" in the indigenous language Quechua. The Ticuna people currently inhabit a part of the park. The park comprises 4,220 square kilometres of jungle, a significant portion of which is annually flooded by the Amazon River during the wet season. The park's elevations vary from 200 to 300 meters above sea level, and temperatures in the park vary only slightly on an annual basis, from 26 to 28 degrees Celsius.
In order to travel to the Amacayacu National Park, travellers must arrive in the city of Leticia then embark by boat upriver to the park itself. In the park visitors can do different activities such as trips along the Amazon river to different islands like Mico's island where you can find hundreds of monkeys, Mocagua's island where one can see Victoria Regia or lotus flower and one of the most interesting activities: a trip up the Amazon River to Tarapoto Lake which has botos (Amazon river dolphins).
