The ruined 13th-century castle is one of Sion’s defining images, dramatically set on the hill opposite Valère. Walk up for the walls, valley panorama, and the best sense of why this was a strategic medieval town; combine it with Valère in one energetic half-day.
1h FreeGo in the morning or late afternoon, when the uphill walk is cooler and the light is better.
Pairs with: Basilique de Valère (Tourist attraction) · Old Town of Sion · Tour des Sorciers
Valère is the essential counterpart to Tourbillon: a fortified hilltop church with exceptional views and a deeply medieval setting. Its church and history collections reward more than a quick photo stop, so allow time before or after the walk across to the castle ruins.
1.3h Walk upArrive near opening for the quietest church interior and coolest climb.
Admission is normally bought on arrival; check seasonal opening hours, especially outside summer.
Pairs with: Château de Tourbillon (Tourist attraction) · Valais History Museum (Tourist attraction) · Old Town of Sion
The Cathedral of Our Lady anchors the lower old town, with a Gothic church built around much older foundations and a distinctive Romanesque tower. It is an easy, worthwhile stop while wandering between the rail station, Place de la Planta, and the two hilltop sights.
30m FreeVisit outside service times for a better look around.
Pairs with: Old Town of Sion · Hôtel de Ville de Sion · Kirche Pfarrei St. Theodul
Sion’s compact old town links the cathedral, civic buildings, lanes, and the climbs to Valère and Tourbillon into one walkable experience. Use it as the connective tissue of a first visit rather than rushing between isolated pins; cafés and wine bars make a natural break between hill climbs.
1.5h FreeStart in the morning, then save the castle hills for later light if the weather is cool.
Pairs with: Sion Cathedral · Basilique de Valère (Tourist attraction) · Tour des Sorciers
This compact cantonal museum explains the unusually varied natural world of Valais, from Alpine environments to the Rhône valley. It is a good rainy-day choice or a focused complement to the history and art museums, rather than a major destination for a short sunny visit.
1h Walk upWeekday afternoons are generally quiet.
Buy on arrival; opening days and hours can be limited, so check before making a special trip.
Pairs with: Valais Art Museum (Tourist attraction) · Valais History Museum (Tourist attraction) · Old Town of Sion
The art museum is a concise introduction to Valais artists and regional visual culture, housed in historic old-town buildings. It is most valuable for museum-minded visitors and works well as part of a cantonal-museum afternoon.
1h Walk upGo on a weekday or during the quieter early-afternoon period.
Walk-up entry is normally sufficient; verify opening hours, which may vary by season.
Pairs with: Valais Nature Museum (Tourist attraction) · Valais History Museum (Tourist attraction) · Sion Cathedral
The history museum gives the Valère hill more substance, using the site and its collections to trace Valais from prehistory through the medieval period. Choose it if you want context for the castles and old town rather than just the views.
1.3h Walk upVisit at opening, before the hill becomes busy with walkers.
Entry is usually available on arrival; check seasonal hours before climbing the hill.
Pairs with: Basilique de Valère (Tourist attraction) · Château de Tourbillon (Tourist attraction) · Valais Art Museum (Tourist attraction)
Europe’s great concrete-dam spectacle is a serious Valais day trip, not a Sion city sight: the scale and high-mountain engineering are the point. Use it if you have a car or are deliberately building a regional itinerary, ideally with a reservoir or hiking day.
2h Walk upAim for a clear morning; mountain weather and seasonal road access can shape the visit.
The exterior viewpoints are accessible without a major reservation; guided interior visits and seasonal transport should be checked ahead.
Pairs with: Nendaz
This well-made Zermatt museum tells the human story behind the Matterhorn, especially the 1865 first ascent, and is more useful than it sounds on a bad-weather day. It is far from Sion, so treat it as part of a dedicated Zermatt overnight or day trip, not a city add-on.
1h Walk upUse it in the afternoon or when the Matterhorn is clouded in.
Tickets are normally available on arrival; check current opening hours in shoulder season.
Pairs with: Kirchbrücke · Mountaineer's Cemetery
Zermatt’s mountaineers’ cemetery is a restrained, moving stop that makes the risks and history of Alpine climbing tangible. It takes little time but adds real context before or after the Matterhorn Museum.
20m FreeVisit early or near dusk, when it is especially quiet.
Pairs with: Matterhorn Museum - Zermatlantis · Kirchbrücke
The 14th-century Witch Tower is a compact but unusually evocative remnant of Sion’s defensive past, later used as a prison and associated with witch interrogations. See it while walking the old town; its value is historical context, not interior sightseeing.
15m Free
Pairs with: Old Town of Sion · Hôtel de Ville de Sion · Château de Tourbillon (Tourist attraction)
This parish church is a pleasant old-town architectural stop rather than a reason to cross town. Include it on a self-guided stroll if its doors are open, especially after the cathedral, but do not plan a day around it.
15m Free
Pairs with: Sion Cathedral · Hôtel de Ville de Sion · Old Town of Sion
Sion’s town hall is a handsome civic building that gives an old-town walk some texture, especially around the central squares. Treat it as an exterior stop and a useful waypoint rather than a standalone attraction.
10m Free
Pairs with: Sion Cathedral · Old Town of Sion · Tour des Sorciers
This small chapel is an atmospheric detail for visitors already exploring Sion’s historic core. It is not a primary sight, but it adds a quiet pause and rewards those who enjoy seeking out lesser-known sacred buildings.
10m Free
Pairs with: Old Town of Sion · Sion Cathedral · Hôtel de Ville de Sion
Nendaz is a mountain-resort base and gateway to the 4 Vallées rather than a compact sightseeing attraction. It is worthwhile for lifts, walking, skiing, or as a practical stop before continuing toward the high-valley landscapes around Grande Dixence.
3h Walk upFor hiking or views, start early before afternoon clouds build.
Village access is free; buy lift tickets online or at the station when using mountain infrastructure.
Pairs with: Grande Dixence dam
This long suspension bridge above the Matter Valley is a memorable hiking objective, with the walk to it being as important as the crossing. It is not near Sion, and it suits confident walkers who can handle changing mountain weather and an exposed span.
3h FreeStart early on a clear weekday; avoid it in storms, high winds, or icy conditions.
Zermatt’s small church bridge is a classic, free Matterhorn-view photo point when conditions are clear. It is a short stop, best folded into a village walk rather than treated as a destination by itself.
15m FreeGo at dawn for the clearest light and the fewest photographers.
Pairs with: Matterhorn Museum - Zermatlantis · Mountaineer's Cemetery
Chandolin is a high, traditional Val d’Anniviers village best used as a scenic base for walks, ski days, or a slower mountain overnight. Its appeal is setting and access to trails, not a checklist of individual monuments.
2h FreeArrive early for hiking and expect afternoon cloud or storms in summer.
Pairs with: Albinen
Albinen is a remarkably preserved Valais hillside village of dark timber buildings, steep lanes, and broad valley views. Go for a short walk and the atmosphere of an old mountain settlement, preferably combined with other Leukerbad-area plans.
1h FreeLate afternoon brings softer light on the wooden houses and valley.
Pairs with: Chandolin
This is primarily FC Sion’s home ground, not a sightseeing stop in its own right. Go only if a Swiss Super League match or another event coincides with your stay; otherwise spend the time in the old town and on the castle hills.
2h Book ahead
For FC Sion matches, buy online once fixtures are confirmed; ordinary league games do not usually require booking weeks ahead.
The Ice Palace is a short, playful component of the Jungfraujoch excursion, with carved ice corridors and sculptures. It is nowhere near Sion and should not drive an itinerary on its own; visit only if you are already committing to the costly full Jungfraujoch rail trip.
25m Book aheadTake an early mountain departure for clearer weather and less congestion.
Reserve the Jungfraujoch rail journey in advance in high season or for a preferred departure, though it is not typically a weeks-ahead sellout.
