Lake Izabal, Freshwater lake in Izabal Department, Guatemala.

Lake Izabal is Guatemala's largest freshwater body, stretching across the eastern region with a landscape of dense jungle, small settlements, and coves. The water connects inland areas to the Rio Dulce, which flows toward the Caribbean Sea and defines the lake's drainage system.

The fort of San Felipe was built in 1652 where the lake connects to the Rio Dulce to defend Spanish colonial trade routes from Caribbean pirates. This stronghold controlled access between inland territories and coastal ports during the colonial period.

Q'eqchi' Maya communities around the lake depend on fishing as an integral part of their diet. The jaiba crab is an ingredient of tapado, a typical dish of the Garifuna community of Livingston. The castle of San Felipe de Lara, built in 1652, can be visited on the lake's perimeter.

The lake is best accessed by boat, and water conditions are calmer during the dry season when visibility is better for exploring the shoreline and coves. Local fishing boats and larger vessels regularly use the water as a working transport route.

The lake holds a freshwater shark among its catch, alongside the chombimba or red mojarra, the fish most prized locally and sold at high prices in Izabal markets. The cholaico shrimp, about 30 cm long with large claws, is harder to find and costs more than lobster.
