Aigrefoin

Un trail incontournable sur la Station de Trail de Bures sur Yvette. Une grande partie du parcours sera très vallonnée essentiellement en forêt (jusqu'au kilomètre 13) puis un court final roulant par les bassins de retenues autour de l’Yvette.

At 16.6 km, this is a solid full-day hike. At an average walking pace you can expect to complete the route in roughly 3 hours and 41 minutes.

The route forms a complete loop, returning you to where you started. This makes logistics simple and the outing entirely self-contained. The trail is officially waymarked as 4, so look out for the trail markers along the way.

This is a Local Walking Network (LWN) trail — a community-level route perfect for exploring the immediate surroundings, popular with locals and visitors alike.
