Haff Réimech Nature Reserve | Luxembourg City

Haff Réimech is a 313-hectare nature reserve and wetland located in the Moselle Valley, near the tripoint where Luxembourg, Germany, and France meet. While not in Luxembourg City proper, it is the country's premier birdwatching destination and a critical ecological site.

Visual Characteristics

The reserve is a mosaic of approximately 30 small lakes and ponds, extensive reed beds, and marshy meadows. Its most striking architectural feature is the Biodiversum, a futuristic visitor center built on an artificial island. Designed by Valentiny HVP, the timber-clad building resembles an overturned ship's hull, a nod to ancient Celtic dwellings. The landscape is bordered by the Moselle River to the east and steep, terraced vineyards to the west.

Location & Access Logistics

The reserve is located in Remerschen, approximately 25 kilometers (a 30-minute drive) southeast of Luxembourg City.

By Car: Accessible via the A13 highway, exiting toward Schengen or Remerschen. Free parking is available at the Biodiversum (5, Bréicherwee).

Public Transport: Bus lines connect Luxembourg City (from the Gare Central or Kirchberg) to Remerschen and Schengen. The "Remerschen, Al Schoul" bus stop is a 10-minute walk from the entrance.

Trails: The site features two "Nature Discovery Trails" (1.9km and 5km), both of which are flat and stroller-friendly.

Historical & Ecological Origin

The ponds are man-made, resulting from intensive gravel and sand extraction that began in the 1940s. After extraction ceased, the pits flooded, creating a unique "ersatz-habitat." It was designated a nature reserve in 1998 and is one of Luxembourg’s two Ramsar sites (wetlands of international importance). Archaeological digs in the area have uncovered evidence of human settlement dating back 30,000 years, including mammoth remains and a Roman villa.

Key Highlights & Activities

Birdwatching: 260 of the 330 bird species recorded in Luxembourg have been spotted here. Key species include the Great Crested Grebe, Little Bittern, and Kingfisher.

Observation Hides: Six discreet wooden huts are positioned along the trails for wildlife viewing and photography.

Biodiversum: Houses interactive exhibitions on three floors detailing the region’s history, underwater ecosystems, and bird conservation.

Recreation: Adjacent to the reserve are the Baggerweieren (Remerschen Lakes), which offer seasonal swimming, stand-up paddleboarding, and fishing.

Infrastructure & Amenities

The Biodiversum serves as the main hub, containing educational spaces, public restrooms, and a gift shop. The center is open Tuesday through Sunday (10:00–17:00). 5G coverage is generally excellent throughout the reserve. The discovery trails are mostly barrier-free and accessible for wheelchairs.

Best Time to Visit

Spring (April–June) is the peak season for observing courtship displays and listening to the "open-air concert" of migratory birds. Winter is ideal for spotting rare northern waterfowl like the Smew. Early morning and late afternoon offer the best light for photography from the hides.

Facts & Legends

The reserve is not "wild" in the traditional sense; it is an artificially maintained ecosystem that must be carefully managed to prevent the reed beds from overgrowing and drying out. Local lore connects the surrounding hills to ancient Celtic and Roman traditions, reinforced by the archaeological discovery of a ritual human burial site nearby.
