The route begins in the forest, with birdwatching available from observation posts. Then the landscape becomes more undulous as you climb Slag heap 115 (viewpoint over the coalfield) and return via the miners' cottages.

A route that will take you to the foot of slag heap 122 (known as the ‘Volcan’ slag heap). You’ll walk up old ‘cavaliers’ (paths that linked the pits together), where flora and fauna have reclaimed their place, and climb one of the twin slag heaps of the ‘Pays à part’, rising to an altitude of 180 metres (offering a magnificent view).

This route will first take you through the Offlarde and Phalempin forests. The landscape then becomes more lunar as you skirt around slag heap 108 and climb slag heap 122 (viewpoint over the mining basin).

An itinerary that will take you to Europe's king of slag heaps! You'll first discover the former 11/19 base with its headframes and mining buildings currently being converted. You'll also enjoy a few pleasant passages through the undergrowth.

A route that takes you through the Fouquières marshes. You'll climb the wooded slag heap 83, offering a view of a mysterious artificial valley. You'll then head for slag heap 94 (staircase slag heap), passing the schlamm bins (storage of mining waste) and the Harnes fishing pond. Return along the path that runs alongside the Lens canal.

This route will take you to the top of the flat 80 slag heap (shaped like a plateau), offering a beautiful view of the mining basin and the Artois hills. The rest of the route follows the course of the Souchez river in a green and peaceful setting.

A route that will take you to the summit of slag heap 107, a fully wooded slag heap. You will follow old mining sidings, which are former railway tracks. You will walk alongside ponds with a bucolic charm, then cross through wild woods or farm tracks with unobstructed views.

A route that takes you from the former 9-9bis pit in Oignies, with its renovated buildings that will transport you back several decades. You will then cross the Bois de Gosse and stop at the wildlife observatory. The landscape will take on a more lunar appearance as you climb the slag heap, before finally returning to the pit via the old mining sidings (rail tracks).

This itinerary takes you to Europe's longest slag heap, which stretches over 2km and fills an ancient valley. You'll enjoy views over the coalfield and the Artois hills. At times, you'll have the impression of walking along a mountain ridge. An entirely wooded terril, it is a reserve for numerous species.
