If you’re spending time in Switzerland in the Swiss canton of Valais, Sion is a really easy and lovely day trip to do. It’s well connected by train, and from the moment you arrive, you’ll spot two impressive hilltop landmarks that have to be explored: Tourbillon Castle and the Basilique de Valère. Just be warned — both involve a bit of climbing.
Tourbillon Castle: Views With a Side of Climbing
Tourbillon is a dramatic 13th-century ruin overlooking the town. It’s open daily from 10:00 to 18:00 (March to November) and offers fantastic views from the top.
From the train station, it’s about a 30-minute walk. Most of the way to the castle is straightforward, but the final section is rather steep, rocky, and just when you think you’ve reached the top, there’s more. But the panoramic view over Sion and the surrounding vineyards makes the effort worthwhile.
Basilique de Valère: Fortified and Full of History
Directly across the valley, on another hill, stands the Basilique de Valère, a fortified church dating back to the 11th century. It’s home to one of the world’s oldest playable pipe organs, built around 1435.
Getting there means heading down from Tourbillon Castle and climbing another hill, but thankfully, this path is better maintained and not as steep. The church is peaceful and atmospheric, with beautiful views back toward the castle.
Between the Two: A Well-Placed Break
In the small square between the two hills, you’ll find Café L’Entre 2 — ideally located for a drink and a rest. I am far too old for all these hills, so if, like me, you need a coffee or something cold and fizzy after that exercise, it’s a great place to pause between climbs.
Wine Tastings… But Not This Time
Vineyards surround Sion and are well known for their local wines. Wine tours are available, but the only one running during my visit started at 5 PM — alas, too late for me, as I would have missed the last bus back up the mountain to Champex-Lac, where I was house-sitting.
You can pre-book your wine tour here. If you’re travelling solo and encounter a “minimum two people” requirement—totally frustrating for solo travellers!—simply contact the tour operator directly. They’re often able to add you to an existing booking or make an exception, even if their online system won’t let you book alone.
Fortunately, most of the wine bars in town offer tastings, and I can confirm: Valais wine is rather good.
Friday Market and a Stroll Through the Old Town
If you’re in town on a Friday, don’t miss the Old Town Market, which has been running year-round since 2003. It’s open from 08:00 to 14:00 and features local produce, cheeses, crafts, and more.
The market stretches along Rue du Grand-Pont, Rue de Lausanne, Rue du Rhône, and Espace des Remparts — all great areas to explore, even when the market isn’t on.
And if it’s not a Friday? Still take the time to wander the old town. Cobbled streets, medieval architecture, and quiet little squares give it plenty of charm. While you’re exploring the old town, be sure to look up- Sion’s astronomical clock is a beautifully preserved 17th century timepiece featuring zodiac signs, lunar phases and calendar rings.
Where to Eat in Sion
There are numerous dining options in Sion. I had a lovely lunch at Les Voisins on Rue du Grand-Pont — a cosy spot with good food and a friendly atmosphere, and a waiter who understood my abysmal attempt at French. Great after all the climbing and walking.
Final Thoughts on Sion
Sion is compact, full of character, and perfect for a day trip or even longer. There’s history, scenery, and plenty of ways to reward yourself — whether that’s with castle views, a glass of wine, or just a sit-down in the square with something cold. Just be prepared for a few hills along the way.
