Eikenberg, Mountain pass in Maarkedal, Belgium.

Eikenberg is a mountain pass located in the Flemish Ardennes that stretches approximately 1.2 kilometers and reaches an elevation of 82 meters. The route combines sections of historic cobblestone with modern asphalt surfaces.

The pass received official protection status in 1995 as recognition of its importance to local cycling traditions. It featured regularly in the Ronde van Vlaanderen between 1974 and 1996, one of Belgium's most significant cycling races.

The road has become a gathering place for cycling enthusiasts who travel from across the region to test themselves on its slopes. You can feel the weight of cycling tradition in how people move through this place.

The climb runs from the Maarkebeek and the Maarkeweg (N457) up to the Kerselareberg (N8), the intercity road between Oudenaarde and Brakel. The cobbles were repaved in 2025. The Ladeuze lies to the west and the Kapelleberg to the east; the Ronde often turns right into the Kokerellestraat just before the top.

The Eikenberg has been part of the Tour of Flanders 48 times, first in 1956 and again in 2025, when it was the second climb after the Oude Kwaremont. In 2003 roadworks forced the race onto the neighbouring asphalt Ladeuze instead. The cobbles were protected as a monument in 1995 and the slope was repaved in 2025.
