7 Secret Corners of Alsace

For this exploration of the secret corners of Alsace, I deliberately focused on Upper Alsace, a region rich in history and diversity, particularly between Mulhouse and the Swiss border.

During my years of residence in the Sundgau, I had the opportunity to discover lesser-known treasures that deeply impacted me.

As such, I have selected seven sites that particularly captivated my imagination and, in my opinion, deserve to be highlighted.

However, I want to emphasize that Alsace is brimming with many other fascinating places, and I strongly encourage you to share your discoveries in the comments below the article.

Without further ado, let’s embark on discovering these secret corners of Alsace with so much to offer.

1. Village of Lucelle

Nestled at the southern tip of Alsace, on the Swiss border, the village of Lucelle exudes serenity.

Surrounded by lush hills and vast forests of the Alsatian Jura, this first site of our 7 secrets corners of Alsace feels like stumbling upon a hidden corner “at the end of the world”!

While Luciele offers a haven of peace away from the urban hustle and bustle, it wasn’t always so in the Middle Ages.

Indeed, at the heart of the village stood the influential Lucelle Abbey, of which little remains today.

6. Valdieu Pass (Belfort Gap)

Situated between the Vosges and Jura mountain ranges and halfway between Belfort and Altkirch, the Col de Valdieu is much more than a mere thoroughfare.

Indeed, it’s not quite the mountain pass one might envision, with towering peaks and winding roads traversing mountain landscapes.

Instead, the Valdieu Pass distinguishes itself with its discretion, harmoniously integrated into the undulating landscape of Sundgau, where roads, railways, and canals converge in a unique convergence.

This is the exact site of the Trouée de Belfort, also known as the Porte d’Alsace or Porte de Bourgogne (depending on which side you’re on!).

This strategic pass sees the convergence of the former national road N19, the railway (including the Paris-Rhin-Rhône TGV), and the Rhine-Rhône canal.

Yet, despite its historical importance, the Col de Valdieu exudes a peaceful and serene atmosphere.

Bordered by lush hills and undulating fields, the pass almost fades into the landscape, concealing its secrets in the heart of Sundgau.

Travellers crossing this emblematic site can also marvel at the incredible procession of locks along the canal, adding an extra touch of charm to this escapade in the Alsace countryside.

7. Rebberg Hill in Mulhouse

Our last site of the 7 secret corners of Alsace brings us to the south of the city-centre of Mulhouse. The Colline du Rebberg is a true green lung for the city.

With its astonishing vineyard, belvedere tower offering a panoramic view of the city, and peaceful Alfred Wallach garden, it provides a moment of calm and greenery.
