Mugron is a small hilltop town with a lovely view. Park near the church and visit the Tree of Liberty, planted in the 19th century. It's majestic, and right next to it is a lovely viewpoint. Take a moment to admire the landscape beneath its canopy of trees. Mugrón is easily explored on foot. You'll find plenty to pack for a picnic, and then head to the leisure center: a lake where you can swim and enjoy water slides with the kids. There's a refreshment bar in season and everything you need for a pleasant time with family or friends, at a very reasonable price! The banks of the Adour also offer lovely walks.

Built on the old railway line that connected Saint-Sever to the spa town of Dax, the Chalosse Green Route offers a 34-kilometer stretch on smooth, hard-surfaced ground. The route offers a bucolic atmosphere with landscapes of woods, hills, and meadows. Among the main tourist attractions are the town center of Saint-Sever (whose abbey is a UNESCO World Heritage Site as part of the Santiago de Compostela Route), the villages of Mugron and Montfort with its Chalosse Museum, and Montaut, a charming Chalosse village. The Landes-Chalosse destination will delight cyclists thanks to its green route and numerous hiking trails.
