Welcome to the lock-keeper's house of

Parc naturel régional
Baie de Somme Picardie maritime

Gateway to the Baie de Somme Picardy Regional Nature Park, the Maison éclusière de Long was originally the dwelling occupied by the lock keepers. Today disappeared, the trade of lock keeper allowed the operation of the locks and thus the passage of Freycinet barges and freight boats on the canal. Generally transporting building materials or sugar beet and then finished sugar, river transport at the end of the 20th century saw an evolution with river tourism becoming increasingly important. The last lock keepers of Long left the lock keeper's house in 2002.

The Maison éclusière de Long (rehabilitated by the Somme Departmental Council and managed by the Syndicat mixte Baie de Somme 3 Vallées), located on the banks of the Somme canal, next to the Véloroute, in a village of high tourist interest (18th century castle, Saint-Jean-Baptiste church and its Cavaillé-Coll organ, classified hydroelectric power station) is a strategic place intended to welcome the general public (tourists, hikers, inhabitants, young people). Also located at the entrance to the future Parc Naturel Régional Baie de Somme Picardie Maritime, the future Pays d'Art et d'Histoire Ponthieu Baie de Somme and the Long-Longpré marshland ecopole, the MéL is a strategic point in the heart of the Somme valley.

La MéL offers you a tourist information point as well as an annual entertainment programme (guided tours, nature outings). You can also rent kayaks, paddles or bicycles to discover the area in a different way. Both a starting point for hiking trails or simply a place to stop and relax, everyone can have a good time!
