For those who choose to see the canyon from the lookout points above, there are restaurants and other food service places as well as camping and picnicking facilities. The other two attractions of the park are general ecotourism and extreme sports. The park has hiking paths and sports fishing is allowed sporadically by permit. There are some locations that rent kayaks and other boats. The Amikúu Ecological Park is located within the canyon area, which is accessible by boat from Chiapa de Corzo. The park is divided into three parts; Discover the Canyon, Colors of Chiapas, and Area of Adventure. The first is located in the dock area, with a demonstration of the history of the canyon and a video of its geological formation. There is also a souvenir shop here. The interior of the park contains a 300 meter long zip line. Colors of Chiapas is a small museum which exhibits the traditional dress and native musical instruments of the state's indigenous peoples. The Area of Adventure takes visitors on a tour of the rainforest area, which include a suspension bridge. It also has a herpetarium, an aviary and enclosure for jaguars and one for crocodiles.
