GR1 and GR22 Stage 1: For our final trek we are combining portions of two different GR trails to hike to our destination of the Notre-Dame Cathedral in Paris.
The GR1, known as the “Tour of Ile-de-France,“ is a 350-mile hiking loop around the Paris metropolitan area. We joined this path in the town of Rambouillet to begin our first stage.
The trail took us almost immediately into the gardens and canals of the Chateau de Rambouillet. French King Francis I, who we had already encountered during several chateau visits in the Loire Valley, died at this castle in 1547. Later, the chateau was the summer residence of the Presidents of France from 1896 until 2009.
After getting a glimpse of the chateau from the gardens, we left the site to venture through a couple of small villages before arriving at the Foret Domaniale de Rambouillet (Rambouillet National Forest).
This forest is one of the largest in France, covering about 77 square miles. Historically it was used by French kings for hunting. As we hiked through the densely wooded area for the remainder of the stage, we observed pine, oak, sycamore, and aspen trees. Some of the trees were quite tall, and we had to crane our necks to view them.
There was a maze of trails to navigate through in the forest, with path options at some intersections going off in four or five directions. Fortunately, we were able to stay on course.
Another highlight of the forest were the “etangs” or ponds. We took a lunch break next to one and counted several herons in the water as we ate.
Because it has rained so much over the past few weeks, a few sections of the path were muddy, slowing us down. However, the trail was generally flat, with just a few climbs. At the top of one ascent we had a nice vista of the forest around us. It was amazing to see so much unpopulated land less than 30 miles from Paris.
At the end of the 15.2-mile stage we turned away from the forest to head into the village of Saint-Leger-en-Yvelines, where we checked into a guesthouse for the night.
