The park's name translates from Frisian to 'The Old Fens'.
The area was officially designated a National Park in 2006 to protect its unique peat moor landscape.
It contains several 'pingo' ruins, which are frozen mounds from the last Ice Age that collapsed to form circular ponds.
The park hosts approximately 100 species of breeding birds annually.
Peat extraction in the Middle Ages created the irregular pattern of pools and land strips now visible.
It is part of the 'Natura 2000' network, a European Union-wide project to protect vulnerable habitats.
Floating fens in the park are dynamic ecosystems that rise and fall with water levels.
The park is a significant transit point for migratory birds moving along the East Atlantic Flyway.
De Alde Feanen is a 2,500-hectare peat wetland and national park in the center of Friesland. The landscape is characterized by a mosaic of lakes, peat bogs, marshes, and willow forests formed by medieval peat extraction. It is a designated Natura 2000 area and one of the largest freshwater wetlands in the Netherlands. The park functions as a major habitat for over 450 plant species and diverse bird populations, including the marsh harrier and the cormorant. Water transport is the primary method of navigation, as large portions of the park are inaccessible by land. The area features a network of marked sailing, canoeing, and cycling routes. Visitors can observe historical 'pingo' remnants and various water management structures that regulate the regional water table. The park is managed through a collaborative effort to maintain open water habitats and floating fen vegetation.

Rent an electric boat or canoe to access the narrow, shallow waterways that motorized speedboats cannot reach.
Bring binoculars to observe bird life from the designated observation hides.
Check local wind conditions before heading out on the larger lakes, as weather can shift rapidly in the open fen landscape.
Attempting to traverse the marshy interior on foot, as much of the terrain is water-logged peat and requires boardwalks or boats.
Visitor center exhibits remain open year-round, but water-based activities are restricted or discouraged during winter months due to potential ice and seasonal wildlife protection.
Maintain a quiet distance from nesting bird areas; follow marked navigation channels to protect fragile reed beds.
