The hiking loop starts at the Col du Marchairuz and leads in 45 minutes past eight informational markers and two vantage points. On the 1.8 kilometer trail hikers get acquainted with many of the nature park’s (Parc Jura vaudois) secrets. The trail is named after Siméon Meylan, who once rested under a large silver fir tree before crossing the Marchairuz. The trail is accessible from spring to autumn.
