Why is Lake Atitlan a must-see?
Why is everybody talking about this lake? Is it really worth a visit?
“The most beautiful lake in the world!"
Alexander von Humboldt (German explorer and naturalist)
"Lake Como, it seems to me, touches on the limit of permissibly picturesque, but Atitlán is Como with additional embellishments of several immense volcanoes. It really is too much of a good thing."
Aldous Huxley, Beyond the Mexique Bay travel book (1934)


Where is Lake Atitlan?

Lake Atitlan as one of the several lakes in Central America is considered among the most beautiful lakes in the World. It is located in the southern part of Guatemala, in the Guatemalan Highlands of the Sierra Madre mountain range, about 50 kilometres (31 mi) west-northwest of Antigua.

How was it formed?

The first volcanic activity in the region occurred about 11 million years ago, and since then the region has seen four separate episodes of volcanic growth and caldera collapse, the most recent of which began about 1.8 million years ago and culminated in the formation of the present caldera.
It is the deepest lake in Guatemala, with a maximum depth of approximately 340 meters (1,120 ft). Atitlán is technically an endorheic lake, feeding into two nearby rivers rather than draining into the ocean. It is shaped by deep surrounding escarpments and three volcanoes on its southern flank. The lake basin is volcanic in origin, filling an enormous caldera formed by an eruption 84,000 years ago.

About the three volcanos?

Volcán Atitlán lies on the southern rim of the caldera, while Volcán San Pedro and Volcán Tolimán lie within the caldera. San Pedro is the oldest of the three and seems to have stopped erupting about 40,000 years ago. Tolimán began growing after San Pedro stopped erupting, and probably remains active, although it has not erupted in historic times. Atitlán has developed almost entirely in the last 10,000 years and remains active, with its most recent eruption having occurred in 1853.

How is the life around the lake?

In 1955, the area around Lake Atitlán became a national park. The lake was mostly unknown to the rest of the world, and Guatemala was seeking ways to increase tourism and boost the local economy. It was suggested by Pan American World Airways that stocking the lake with a fish prized by anglers would be a way to do just that. As a result, an exotic non-native species, the black bass, was introduced into the lake in 1958. The bass quickly took to its new home and caused a radical change in the species composition of the lake. The predatory bass caused the elimination of more than two-thirds of the native fish species in the lake and contributed to the extinction of the Atitlan grebe, a rare bird that lived only in the vicinity of Lake Atitlán.
A unique aspect of the climate is what is referred to as Xocomil (of the Kaqchickel language meaning "the wind that carried away sin"). This wind is common late morning and afternoon across the lake; it is said to be the encounter of warm winds from Pacific meeting colder winds from the North.
In August 2015 a thick bloom of algae known as Microcystis cyanobacteria re-appeared in Lake Atitlan; the first major occurrence was in 2009. Bureaucratic red tape has been blamed for the lack of action to save the lake. If current activities continue unchecked, the toxification of the lake will make it unsuitable for human use. A bluish gray stream of wastewater descending through the town of San Pablo La Laguna and emptying directly into the lake can be clearly viewed along the shoreline trail as you enter San Pablo.
The area supports extensive coffee and avocado orchards and a variety of farm crops, most notably corn and onions. Significant agricultural crops include: corn, onions, beans, squash, tomatoes, cucumbers, garlic, chile verde, strawberries and pitahaya fruit. The lake itself is a significant food source for the largely indigenous population.

Around the lake

The lake is surrounded by many villages in which Maya culture is still prevalent and traditional dress is worn. The Maya people of Atitlán are predominantly Tz'utujil and Kaqchikel. During the Spanish conquest of the Americas, the Kaqchikel initially allied themselves with the invaders to defeat their historic enemies, the Tz'utujil and K'iche' Maya, but were themselves conquered and subdued when they refused to pay tribute to the Spanish.
Santiago Atitlán is the largest of the lakeside communities, and it is noted for its worship of Maximón, an idol formed by the fusion of traditional Mayan deities, Catholic saints, and conquistador legends. The institutionalized effigy of Maximón is under the control of a local religious brotherhood and resides in various houses of its membership during the course of a year, being most ceremonially moved in a grand procession during Semana Santa. Several towns in Guatemala have similar cults, most notably the cult of San Simón in Zunil.
While Maya culture is predominant in most lakeside communities, Panajachel has been overwhelmed over the years by Guatemalan and foreign tourists. It attracted many hippies in the 1960s, and although the civil war caused many foreigners to leave, the end of hostilities in 1996 saw visitor numbers boom again, and the town's economy is almost entirely reliant on tourism today.

Under the lake

Several Mayan archaeological sites have been found at the lake. Sambaj, located approximately 55 feet below the current lake level, appears to be from at least the pre-classic period.[13] There are remains of multiple groups of buildings, including one particular group of large buildings that are believed to have been the city center.
A second site, Chiutinamit, where the remains of a city were found, was discovered by local fishermen who "noticed what appeared to be a city underwater". During subsequent investigations, pottery shards were recovered from the site by divers, which enabled the dating of the site to the late pre-classic period (300 B.C. – 300 A.D.), more specifically 250 AD.
People from all around the World come to see Lake Atitlan because of the uniqueness and the balance of the nature. They say every village and town around the lake has a different character: enjoy the perfect view from Santa Crúz, practice yoga in San Marcos, meet travellers in Panajachel, learn from local Mayans at San Juan and have a good party in San Pedro.  
Come, and see it for yourself!
