The Old Bridge of Balizy, or the Templar Bridge, spans the Rouillon. Hidden in the heart of the Templar Woods, and surrounded by magnificent forest paths, it is a superb place for a mountain bike ride.

I am unable to judge whether this bridge is actually connected to the Knights Templar Order, as described in the highlight title (the exact name would be “Poor Knighthood of Christ and the Solomonic Temple in Jerusalem”). In this case it would have to go back to the 12th or 13th century.

There is a pedestrian path along the Yvette near Old Orsay, and it passes under this pretty little stone bridge.

This 1.5 hectare lake is a very pleasant place to run. Bordered by the Yvette, it has a path that runs along both the body of water and the river, giving the impression of crossing the waters. Its small central island is also very pretty.
