Chalupská slať, Peat bog in Svinná Lada, Czech Republic.

Chalupská slať is a transitional peat bog between a valley and a mountain raised bog in Svinná Lada, at 900–950 m. A 260 m wooden boardwalk, built in 1974, ends on a small platform at the edge of Chalupské jezírko, the country's largest peat lake at 1.3 ha.

This bog formed at the end of the last Ice Age and developed into its present shape over thousands of years. The peat layers record natural climate shifts and vegetation patterns that reveal the region's environmental history.

The site draws nature enthusiasts and school groups who come to observe rare plants and animals adapted to boggy conditions. Pathways are designed to let visitors experience the ecosystem without causing harm to this fragile environment.

The wooden boardwalk is well maintained and easy to walk on, but sturdy footwear is recommended as conditions can be muddy. Information signage is clearly posted, and a visitor center nearby provides helpful context about what you will encounter along the trail.

The 260 m boardwalk, built in 1974, ends at a small platform on the edge of Chalupské jezírko, a 1.3 ha peat lake, the largest in Czechia. The peat layer here reaches up to 7 m thick, an estimated 2,340,000 m³. The lake holds several floating islands where protected plants such as round-leaved sundew grow.
