Circuit des Trois Châteaux du Jura alsacien
Loading route and elevation profile…
Three castles across the Sundgau
The ruins of Landskron, Ferrette and Morimont provide the main landmarks. The circuit links them through the wooded hills and valleys of the Alsatian Jura; allow time for visits as well as walking.
Plan four walking days
The OSM itinerary describes four sections: Leymen–Ferrette, Ferrette–Morimont, Morimont–Lutter and Lutter–Leymen. Use these as overnight planning references, rather than confirmed bookings or guaranteed daily distances.
Walking the hills
The tourist office gives an overall moderate difficulty, with forest paths and some steep climbs. Access to the ruins requires care; the accumulated distance also means being comfortable walking on successive days.
Arrange accommodation and meals
The official package offers four days and three hotel nights, with a luggage transfer option. Independent walkers can use it as a planning reference, then confirm accommodation and services separately at each stop.
Choose your season
The tourism offer recommends spring, summer and autumn. All three castles are listed as freely accessible year-round; this does not establish trail condition, the absence of works or access to every part of the route.
Leave time for the ruins
Build castle visits into each walking day. Walls, steps and rocky approaches are explored on foot; not all forest and heritage sections are suitable for pushchairs.
