South of the Vosges a mix of sedimentary rocks forms the low land around Belfort, where the GR5 goes through areas of farming and forestry.

Just south of Vandoncourt the striking rock arch of Pont Sarrazin (Section 8) is the first unmistakable sign that the path has reached the limestone that forms the basis of the scenery for the rest of the route to Lake Geneva. The limestone of the Jura creates a landscape distinct from the Vosges. Rivers have cut deep gorges and often flow underground through caverns. One of the highlights of the GR5 is where it follows the River Doubs as it flows through a series of wooded gorges along the Swiss frontier (Section 9).

The GR5 then climbs onto the high plateau of the Jura where the limestone extends to great depths. Folded by earth movements and split by faults, the whole region was scoured by ice so that the resulting plateau is far from flat, instead forming an undulating landscape at about 1000m, now largely covered by forest. Elevated lookout points such as Roche Bernard give expansive views.
