🇨🇭 Sion — Family Travel Guide

Country: Switzerland
Last Updated: May 2026

Overview

Sion is the small Swiss city with the big castle skyline: two rocky hills rise directly above the old town, one crowned by the ruined Château de Tourbillon and the other by the fortified Valère basilica and Valais History Museum. For families, that gives the city an immediate storybook hook — you can arrive by train, eat a quick crêpe or gelato, and be climbing toward medieval towers within minutes.

The appeal is not blockbuster Switzerland in the Lucerne/Interlaken sense. Sion is quieter, warmer, more local, and better as a base for Valais adventures than as a first Swiss city break. Use it for castle walks, vineyards, swimming at Domaine des Îles, Alaïa Bay surf sessions, and day trips to odd alpine sights like the Pyramids of Euseigne or the Grande Dixence dam. It works particularly well for families who want Switzerland without wall-to-wall tour groups.

Why families love it:

• Two castle hills create an easy, memorable first-day adventure
• Sunny Valais climate means more outdoor days than many Swiss mountain towns
• Compact old town with cafés, fountains, and mostly walkable lanes
• Domaine des Îles gives you lake swimming, playgrounds, camping, and picnic space just outside town
• Excellent base for Sierre, Martigny, Ovronnaz, Evolène, and Hérens valley day trips
• Food is more relaxed than in big Swiss resorts: raclette, crêpes, pizza, burgers, bakeries, and ice cream are all easy wins

⏰ Best Time to Visit with Kids

Pro tip: Sion can feel surprisingly hot in summer. Do the castle hills before lunch, then switch to Domaine des Îles, Alaïa Bay, or a mountain day trip in the afternoon.

🚗 Getting Around

Train Sion sits on the main Rhône valley rail line between Geneva, Lausanne, Visp, and Brig. From Geneva Airport, trains take roughly 2 hours with an easy change at Lausanne or direct regional options depending on timing. From Zurich, expect around 2.5–3 hours. The station is a flat 10–15 minute walk from the old town.

Walking The old town is compact, but the castle hills are real climbs with steps and uneven paths. Bring a carrier for toddlers rather than relying on a stroller for Valère and Tourbillon.

Bus / local transport Local buses connect the station with Domaine des Îles, Alaïa Bay, and surrounding neighbourhoods. For day trips into side valleys, check schedules carefully; Swiss public transport is reliable, but rural frequency can drop sharply outside peak times.

Car A car is not needed for the town itself, but it makes the Valais day trips much easier — especially Grande Dixence, Euseigne, Ovronnaz, and village-hopping in the Hérens valley. Parking in central Sion is manageable compared with larger Swiss cities.

Swiss Travel Pass / Half Fare Card If Sion is part of a wider Switzerland trip, the Swiss Travel Pass or Half Fare Card can save a lot on trains and mountain transport. For a Sion-only weekend, calculate before buying; many local attractions are inexpensive or free.

🏰 Castle Hills & Old Town

1. Basilique de Valère & Valais History Museum ⭐

Valère is the better first castle hill for families: the fortified basilica, old stone lanes, and museum sit inside a compact medieval enclosure with sweeping views across Sion and the vineyards. The Valais History Museum is unusually atmospheric because it is housed right on the hill, using archaeological objects, models, and multimedia to tell the region’s story from prehistory to the present.

• Age suitability: All ages for the hill; museum best for 6+
• Cost: Hill and exterior areas free; museum tickets vary, with family reductions often available
• Time needed: 1.5–2.5 hours
• Location: Place Maurice-Zermatten, above the old town
• ⚠️ Honest note: The approach is steep and cobbled. It is not stroller-friendly.
• Pro tip: Start here rather than Tourbillon if travelling with younger children. You get the views and the medieval atmosphere with less scrambling.
• Website: musees-valais.ch

2. Château de Tourbillon ⭐

Tourbillon is the ruined castle on the opposite hill — more dramatic, more exposed, and more adventurous. Children who like climbing, walls, and “proper ruins” will prefer it. The path zigzags up from town and rewards the effort with superb views of Valère, the Rhône valley, and the surrounding peaks.

• Age suitability: Best for 5+; younger kids need close supervision
• Cost: Free exterior access; interior opening varies seasonally
• Time needed: 1–2 hours
• Location: Chemin de la Poudrière / Tourbillon hill
• ⚠️ Honest note: There are drops, rough ground, and limited shade. Avoid the hottest part of the day.
• Pro tip: Pair Tourbillon and Valère only if your children are good walkers. Otherwise split them across two mornings.

3. Sion Old Town & Maison Supersaxo

Sion’s old town is small but satisfying: arcaded streets, fountains, cafés, and narrow lanes beneath the castle hills. Maison Supersaxo is the quick cultural stop — a 16th-century mansion with a remarkable carved wooden ceiling. It is more “peek in and admire” than a full museum, but it adds texture to an old-town wander.

• Age suitability: All ages
• Cost: Old town free; Maison Supersaxo access depends on events/opening
• Time needed: 1–2 hours
• Pro tip: Use the old town as your food-and-reset zone between hill climbs. Place du Midi and Rue du Grand-Pont have easy restaurants and cafés.

🌊 Water, Play & Active Days

4. Domaine des Îles ⭐

Domaine des Îles is Sion’s family safety valve: a lakeside leisure area with walking paths, picnic lawns, playground space, camping, restaurants, and summer swimming. It is not a polished resort beach; it is a local outdoor zone where children can run, paddle, and decompress after castle-and-culture mornings.

• Age suitability: All ages
• Cost: Outdoor areas generally free; activities/food extra
• Time needed: Half day
• Location: West of town near the Rhône, reachable by bus/taxi/car
• ⚠️ Honest note: Bring water shoes for sensitive feet and check current swimming conditions locally.
• Pro tip: This is the best place to balance a hot Sion day: castles early, lake/picnic late.

5. Alaïa Bay Surf Pool

Alaïa Bay is one of Sion’s most unexpected family attractions: an inland wave pool where beginners can take lessons and confident surfers can book controlled wave sessions. For active tweens and teens, it can be the highlight of the trip — especially because it feels so bizarrely fun to surf beneath Swiss mountains.

• Age suitability: Best for 8+; depends on lesson/session rules
• Cost: Splurge; book sessions online
• Time needed: 2–4 hours
• Location: Route d’Aproz 65, near Domaine des Îles
• ⚠️ Honest note: Not a casual drop-in swimming pool. Sessions, equipment, and lesson slots should be booked ahead.
• Pro tip: Non-surfing parents can still make this a pleasant stop by combining it with Domaine des Îles.

6. Bisse de Clavau Vineyard Walk

The bisses are historic irrigation channels that contour across Valais hillsides. The Bisse de Clavau above Sion gives families a gentle taste of this landscape: stone walls, vineyards, valley views, and a mostly level path once you are up on the hillside. It is a lovely late-afternoon walk for children who can manage narrow paths.

• Age suitability: Best for 6+; not ideal for runaway toddlers
• Cost: Free
• Time needed: 1.5–3 hours depending on route
• ⚠️ Honest note: Some sections are narrow and exposed. Hold hands with younger kids.
• Pro tip: Go near golden hour. The castle hills and vineyards look far better than they do in harsh midday sun.

🧪 Museums, Animals & Bad-Weather Options

7. Musée de la Nature du Valais

The Valais Nature Museum is useful for a slower day: alpine wildlife, geology, ecosystems, and seasonal exhibitions that help children understand the mountains around them. It is not huge, which is a benefit with younger kids.

• Age suitability: Best for 5–12
• Cost: Modest; check current museum ticketing
• Time needed: 1–1.5 hours
• Location: On the Sion museum hill circuit
• Pro tip: Combine with Valère/History Museum rather than treating it as a standalone half-day.

8. Fondation Pierre Gianadda, Martigny

A strong day-trip choice for families who like sculpture gardens, old cars, Roman ruins, and manageable art galleries. The sculpture park gives kids space to move, while the car collection often wins over children who might not care about the main exhibition.

• Age suitability: Best for 6+
• Cost: Museum ticket; family pricing varies
• Time needed: 2–3 hours plus travel
• Location: Martigny, about 25 minutes by train from Sion
• Pro tip: Pair with Barryland nearby for an easy animal-and-culture day.
• Website: gianadda.ch

9. Barryland — St Bernard Dogs, Martigny

Barryland is the crowd-pleaser in Martigny: a museum and visitor centre dedicated to Switzerland’s famous St Bernard dogs. It is small but memorable, especially for younger children and dog-loving families.

• Age suitability: All ages
• Cost: Ticketed
• Time needed: 1–1.5 hours
• Location: Martigny, near Fondation Pierre Gianadda
• ⚠️ Honest note: Check current dog-walking and puppy-viewing times; the experience varies by season.
• Website: barryland.ch

🎢 Easy Family Day Trips

10. Happyland, Granges/Sierre

Happyland is a small amusement park east of Sion with rides aimed mainly at younger children: carousels, mini-coasters, boats, and fairground-style attractions. It is not Europa-Park, but for under-10s it can be exactly the low-pressure fun day you need.

• Age suitability: Best for 2–10
• Cost: Ticketed; check seasonal opening
• Time needed: Half day
• Location: Near Granges/Sierre, about 20–30 minutes from Sion by car
• ⚠️ Honest note: Opening is seasonal and weather-sensitive. Confirm before promising it to kids.
• Pro tip: Combine with a short Sierre stop or a vineyard-view drive rather than making it a full-day expedition.

11. Labyrinthe Aventure, Evionnaz ⭐

One of the best kid-specific day trips in the lower Valais: a giant maze and outdoor play park with slides, games, and climbing areas. It is much more directly child-focused than most Swiss cultural attractions.

• Age suitability: Best for 4–12
• Cost: Ticketed
• Time needed: Half day to full day
• Location: Evionnaz, west of Martigny
• Pro tip: This is the rainy-week recovery card if your kids are tired of “pretty towns” and need a proper play day.
• Website: labyrinthe.ch

12. Pyramides d’Euseigne

The Pyramids of Euseigne are strange natural rock towers capped by boulders — a quick, memorable geological stop in the Hérens valley. They are not a full-day attraction, but they pair beautifully with a valley drive or Grande Dixence.

• Age suitability: All ages; best for curious 6+
• Cost: Free viewpoint
• Time needed: 20–45 minutes
• ⚠️ Honest note: Treat this as a stop, not the destination.

13. Grande Dixence Dam

A huge concrete dam high in the Valais mountains, reached through dramatic alpine scenery. Older children often find the scale impressive, and in summer there are walks, tours, and cable-car access depending on conditions.

• Age suitability: Best for 7+
• Cost: Viewpoints free; tours/cable car extra
• Time needed: Half day to full day
• ⚠️ Honest note: Mountain weather changes quickly and the road/travel time is significant.
• Pro tip: Check opening dates before going; this is a summer/early autumn plan, not a casual winter outing.

14. Les Bains d’Ovronnaz

Thermal pools are a very Swiss way to save a tired travel day. Ovronnaz is a mountain spa resort above the Rhône valley with warm pools and alpine views — particularly good after hikes or in cooler weather.

• Age suitability: All ages; best when children enjoy pools
• Cost: Ticketed
• Time needed: Half day
• Location: Ovronnaz, roughly 35–45 minutes by car from Sion
• Pro tip: Pack swimwear even if Sion is only a stopover. Thermal baths are the easiest family reset in Valais.

🍽️ Food Experiences for Families

Sion is in Valais, so the must-try food is raclette — melted local cheese scraped over potatoes, pickles, and onions. It is simple, theatrical, and usually a child-friendly Swiss food win if your kids like cheese. The other easy Valais staples are rösti, dried meats, apricot tart, mountain honey, and excellent bread from local bakeries.

For practical family meals, stay near Place du Midi, Rue du Grand-Pont, and the station area. Brasserie du Grand-Pont and Pinte Contheysanne are good for regional food; Don Carlos, Luigia, and Cap Cap cover pizza; Burgerlution and Les Brasseurs are useful casual fallbacks; Hasta Glaces is the obvious ice-cream stop. Around Domaine des Îles, the camping/lakeside restaurants are more convenient than gourmet — useful when sandy, wet children need feeding fast.

Pro tip: Swiss restaurant prices can sting. Balance one raclette/brasserie meal with supermarket picnics, Migros/Coop restaurant lunches, bakeries, and lakeside snacks.

🌊 Day Trips

Sierre & Crans-Montana — Sierre is close by train, and Crans-Montana above it adds lakes, mountain walks, and winter sports. Best with a full day and good weather.

Martigny — The easiest culture-and-animals day: Fondation Pierre Gianadda plus Barryland. Good by train and very manageable with kids.

Hérens Valley — Euseigne, Evolène, and Grande Dixence make a dramatic mountain loop if you have a car. Best in summer or early autumn.

Ovronnaz / Saillon — Thermal pools and mountain views. A softer family day when everyone needs warmth and water.

💡 Practical Tips for Families

• Do castle hills early. Heat and exposed stone make midday climbs much less fun.
• Use carriers, not strollers, for Valère and Tourbillon. The old town is stroller-friendly; the hills are not.
• Keep a water bottle routine. Valais can be dry and hot in summer.
• Check opening days. Smaller Swiss attractions often have seasonal hours or Monday closures.
• Budget honestly. Sion is cheaper than resort Switzerland, but it is still Switzerland.
• Plan one child-led day. Domaine des Îles, Alaïa Bay, Happyland, or Labyrinthe Aventure keeps the trip from becoming all churches and views.

📋 Quick Reference: Activities at a Glance

✈️ Getting to Sion

Sion has a small airport but families should treat Geneva (GVA) or Zurich (ZRH) as the practical gateways. Geneva is usually the simplest: fly Malta–Geneva when schedules work, then take the train along Lake Geneva and through the Rhône valley to Sion. Zurich is also easy by train but longer.

From Malta: Look for direct or one-stop flights to Geneva/Zurich with Air Malta/KM Malta Airlines connections, Swiss, easyJet, or seasonal European routings. If Sion is part of a wider Swiss trip, it pairs well with Lausanne, Montreux, Zermatt, or Lucerne.

Best arrival plan: Land in Geneva by lunchtime, train to Sion, check in, then do old town + dinner on day one. Save the castle hills for the first full morning.
