The most impregnable of the Cathar castles. The Cathars finally surrendered after an 11-month siege. The choice was conversion to the Roman Catholic Church or the stake. 200 Cathars chose the stake...

This castle was the only one of the larger and more famous Cathar castles we were missing... and the visit was totally worth it 🥰

Beautiful view of the "safe mountain" - the somewhat arduous climb is definitely worth it, because from the top you have a fantastic view ☺️

From here a path leads to the Château de Montségur, a ruin from the Cathar era. There is a fee to visit, but you can get up to halfway up the climb. It's worth the detour!

The Château de Montaillou is located in Ariège. It is a medieval fortress already documented in the 13th century which is today in a state of ruin. Located on a slope of Mount Allion, three walls and other vestiges of this construction are still preserved.

For breathtaking panoramic views, consider visiting Montségur Castle, perched atop a 1,207-meter peak with vistas of the Pyrenees. Peyrepertuse Castle, often called 'Celestial Carcassonne,' provides superb views of vineyards and the Corbières massif, sometimes even the Mediterranean. Quéribus Castle also offers spectacular surveillance over the Roussillon plain, from the Mediterranean to the Pyrenees.
The castles in this region are deeply rooted in the history of the Cathars and the Albigensian Crusade. Montségur Castle is famously known as the last stronghold of the Cathars, a site of profound religious persecution. Castles like Peyrepertuse, Quéribus, Puilaurens, Termes, and Aguilar were strategic French royal fortresses, known as the 'Five Sons of Carcassonne,' built to defend the border with Aragon after the Crusade.
While many castles involve steep climbs, the historical context and dramatic settings can be engaging for older children. Peyrepertuse Castle hosts an annual Medieval Festival in August, which can be a fun experience for families. The nearby town of Montségur also has a museum that provides historical context, which can be a good starting point before the climb to the castle.
The region offers various outdoor activities. You can find numerous cycling routes, including gravel biking and touring bicycle options, around Montségur. For example, explore the 'Gravel biking around Montségur' guide or the 'Cycling around Montségur' guide for routes like the 'Bélesta loop from Montségur'. There are also dedicated 'MTB Trails around Montségur' with routes such as 'Gorges de la Frau – Comus loop from Montségur'. You can find more details and routes in the respective guides on komoot.
While Montségur Castle is very popular, you might find a more tranquil experience at some of the other sites. Lordat Castle, a huge fortress extending over a mountain, offers a sense of ancient grandeur. Montaillou Castle, a former fortified castle from the 13th century, is also a ruin that provides a quieter exploration of history.
The best time to visit is generally during spring (April-May) and autumn (September-October) when the weather is milder and more pleasant for hiking and exploring. Summers can be hot, especially for the climbs to the castles, but an annual Medieval Festival is held at Peyrepertuse Castle in August. Winters can be cold and some paths might be challenging due to weather conditions.
Many of the castles, especially those perched on 'pogs' or ridges, involve moderate to difficult climbs. However, Roquefixade Castle, located on the heights of its village, offers wide panoramas and is generally accessible, though the main part may be temporarily closed for renovation. The walk to Montségur Castle is steep but well-trodden.
Peyrepertuse Castle boasts remarkable military architecture with high walls merging with the rock, a Saint-Louis staircase carved from stone, and well-preserved rooms. Puilaurens Castle is a prime example of mountain defense architecture, featuring a heavily defended zigzagging approach path, a barbican, murder holes, and an impressive keep.
Access to many of these remote castles, especially those in the mountains, is often challenging without a car. While some villages might have limited public transport options, reaching the castle sites themselves typically requires a drive and then a walk. Parking is usually available near the base of the castle climbs.
Termes Castle is renowned for enduring one of the hardest and longest sieges of the Albigensian Crusade in 1210, lasting four months against Simon de Montfort's forces. This makes it a compelling site for those interested in the Cathar Wars.
Aguilar Castle is the only one of the 'Five Sons of Carcassonne' that is free to visit. It offers a unique blend of historical significance and natural beauty, with well-preserved ruins and breathtaking views.
