Zoologico miguel Alvarez del Toro is some 20 min ride from the Tuxtla. Here you can find only animals that live in the state of Campeche. You can see crocodiles, monkeys (and other mammels), many different birds and reptiles.
This ZOO was established by Miguel Alvarez who dedicated his life to exploring Campechan wild life and preserving it.
To get there you can take a colectivo. Starting point 7 blocks south of plaza civica (3,5 pesos one way)
One of the top must see activitys in Mexico is deffinetely Cañon del Sumidero.
Driving with a speedboat among the 1000m high cliffs, among crocodiles, variaty of birds, monkeys, beautiful nature, waterfalls, caves... unforgettable.
Sorry, no pictures here, but the life and shops around the large zocalo of this quaint colonial town make it worth the trip if you are in Tuxtla. The zocalo, Plaza General Angel Albino Cors - named after the liberal governor who in 1863 defeated the conservative forces centered in San Cristobal de las Casas who supported the French invasion of Mexico in the time of Maximillan - is a large park area which features an eight-sided Spanish fountain, La Pila, built in 1562, and is said to be modelled after the Spanish crown.
It is easy to forget where you are in the World as your boat cruises along through the canyon. Here, on the lake, you are in what would be a jungle if it wasn't for the 3000 foot cliffs Jungles have monkeys and they have crocodiles. You'll see both here!
Herons, egrets, cormorants, vultures, kingfishers are a few of the bird you can spot as you cruise through the canyon. Unusual bird life or formations within the canyon are usually spotted first by the congregation of the little boats. One huge cliff formation is covered with hanging moss-shaped like a Christmas tree and named appropriately, Arbol de Navidad. Two caves are also on the itinerary - the Cave of Man and the Cave of Silence.
At the heart of a national park, this fantastic canyon has been carved by the Grijalva River over a million years. The canyon is 35 km long, with sheer walls up to 1200 meters high. The river has been dammed here by the mighty Chicoasen Dam - a fine museum exists above the dam where you can learn more about the dam, its construction and the benefits it provides to Mexico - since 1981. Over 20% of Mexico's electricity is generated from the huge turbines set into the cliff walls below the dam. The river was considered unrunnable before the dam, but today you can catch one of the many tourist boats that run through the canyon. The boats take off from near Chiapa de Corso and run down to the dam - about an hour each way with a half hour stop at one of the small restaurants near the dam.
You can also witness the canyon from the western rim. A series of five miradors - lookouts - are sited northeast out of Tuxtla.
