Saldropo was originally a wetland of glacial origin that transformed into a peat bog over thousands of years.
The industrial extraction of peat at this site ceased in the late 20th century, leading to a major restoration project to recover the water table.
The wetland acts as a natural sponge, regulating water flow in the upper Arratia valley.
It is a significant site for the study of paleoclimatology through the analysis of pollen trapped in peat layers.
The surrounding landscape is part of the karst environment characteristic of the Gorbeia massif.
Saldropo is a protected wetland area located within the Gorbeia Natural Park in the Basque Country. The site is a former peat bog that was historically used for commercial peat extraction until its restoration to a natural habitat. It features a flat, circular walking path surrounding the central wetland, which serves as a vital ecosystem for amphibians and dragonflies. The area is defined by its humid landscape, which transitions into beech and oak forests as elevation increases. Informative signposts throughout the site explain the geological processes that formed this natural basin. It is part of the Natura 2000 network due to its high ecological value. The site is accessible via an easy gravel trail, making it suitable for families and casual walkers.
