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.

Saint Bartholomew's Church The old church, built on the same site as the new one, was the castle chapel and previously the seigneurial chapel. The first stone was solemnly blessed on March 19, 1868. It was consecrated in 1869. The church plan is the work of Mr. Ozanne, the departmental architect. Mr. Fraglon, a public works contractor in Villandraut, won the contract for 80,000 francs. The total cost, including furniture and the architect's fees, reached 100,000 francs (€15,244). The church of Poyanne could be considered at the time one of the most impeccable new churches in the diocese: for its size, the height of its vaults, the boldness of the arcades, the harmonious proportions, the unity of style, the regularity of the whole, and the harmony of the details. The church is built in the shape of a parallelogram and without transepts. Its nave consists of a vestibule, a central nave, two side aisles, and a choir with a polygonal chevet flanked on the right and left by a small square chapel. It measures 35m long, 19m wide, and 13m high. The 10m deep choir receives light from the chevet through three long lancet windows. The main nave connects with its side aisles through five large arches that provide as many bays, supported by eight isolated pilasters. The vault rests on real capitals. The gallery is in perfect taste. The porch is very simple, displaying its decoration only at the main door. The patron saint of the church of Poyanne is Saint Bartholomew.
