Montaigu is in the north western region of Pays de la Loire. It's an hour away from the beach and within good driving distance of attractions such as Puy du Fou. There's also a host of castles and abbeys in the wider locality which you'd identify with Pays de la Loire. Car hire from Montaigu is useful for those using the town as a base for their travels.
In the town itself you'll find some pleasant parkland at the Parc du Chateau and Parc des Rochettes, where the ruins of Montaigu's medieval fortifications crop up at regular intervals. Hire a car from Montaigu at our location at Saint Georges de Montaigu.
The centre of Montaigu is framed by the Parc du Chateau and Parc des Rochettes, which provide some nice tranquillity in what is an already laid back town centre. You'll find plenty of shops and amenities scattered throughout the town.
You may have chosen Montaigu as a base from which to explore the seaside as well as Puy du Fou theme park. Puy du Fou is 40 minutes east on the D27; the beach resort of Saint-Jean-de-Monts is just over an hour west on the D753, and the elegant resort of Les Sables-d'Olonne is a similar distance on the D160/D763.
