About us

 

ATi DiVERS is located within La Iguana Perdida Hotel in a beautiful little village called 
Santa Cruz La Laguna on the shores of Lake Atitlan.

 

In the 15 years that we have been diving in this lake we have made over 3000 fun dives, taught
more than 750 people to dive, and issued more than 1500 PADI certifications.

 

We know all the best spots to dive. We know where the best volcanic rock formations are and
where to find the volcanic hot-spots on the lake bed. We can find the biggest crabs, most fish
and most beautiful freshwater plants. 

 

If you want to experience Lake Atitlan from beneath the surface, we are the people to come to!

 

ATi DiVERS and La Iguana Perdida have been in Santa Cruz since 1996 when Deedle Denman, from the United Kingdom, came to take part in an underwater lake mapping project. When the project fell through, she opened a dive centre and hotel instead! Deedle now runs the Iguana with her husband Dave who, incidentally, started out as a hotel guest in 2001.

 

About Lake Atitlan

 

Lake Atitlan is both the deepest and highest altitude (1562m) lake in

Central America and one of the most beautiful lakes in the world. "Atitlan" in

Mayan means "the place where the rainbow gets its colours". The lake is

situated in an area of Guatemala where a string of volcanoes have formed as

the Cocos plate of the Pacific is subducted beneath the Caribbean plate.

 

150,000 years ago a magmatic batholith (a huge subterranean pocket filled

with liquid magma) formed in the area that is now the lake. This was fed by

the Los Chocoyos Batholith, which discharged in a massive, violent eruption around 84,000 years ago. The eruptive column reached heights of between 40 to 60km and dispersed ash over an area from Florida to Ecuador. So much magma had been expelled that only an empty cavity remained. Unable to support the weight of the earth above it, the area collapsed, forming the 18km diameter caldera.
 

Originally 900m deep, the caldera filled over time with rainwater and sediment to create the lake we have today. The caldera is lined with sediment for 300m or so, before being filled with water for another 340m and finally 300m (more or less) of air to the rim of the lake.
