Thun -- The Overlooked Gateway to the Bernese Oberland

TL;DR: Thun (pronounced "Toon") is a historic lakeside town of 44,000 people at the gateway to the Bernese Oberland, featuring a magnificent 12th-century castle, one of Switzerland's most unusual shopping streets (with shops on rooftop level), and a stunning setting where the River Aare flows out of Lake Thun toward Bern. Just 20 minutes from Bern and 30 minutes from Interlaken by train, it is an often-overlooked gem that offers a more authentic and significantly cheaper base for exploring the Jungfrau region.

Quick Facts

Top 5 Things to Do in Thun

1. Visit Thun Castle (Schloss Thun)

Thun Castle sits on a hill above the Old Town and has dominated the skyline since its construction by the Dukes of Zahringen around 1190. The massive keep with its four corner turrets is one of the most recognizable castle silhouettes in Switzerland. Inside, the castle museum covers 800 years of regional history across five floors, including a medieval hall with original wooden ceiling, military collections, and rotating exhibitions. The rooftop platform offers a 360-degree panorama of Lake Thun, the Aare, the Old Town, and -- on clear days -- the Eiger, Monch, and Jungfrau. Entry: CHF 12 adults, CHF 4 children 6-15 (2026 prices). Open daily February to November; reduced hours in winter. Allow 1-2 hours.

2. Cruise Lake Thun (Thunersee) by BLS Boat

Lake Thun is one of the Bernese Oberland's two great lakes, stretching 18 km from Thun to Interlaken with the Niesen, Stockhorn, and Bernese Alps as a backdrop. The BLS fleet operates regular scheduled boats from April to October, with the full circuit from Thun to Interlaken taking approximately 2 hours. A round trip costs CHF 62 (2026 prices) -- or it is completely free with the Swiss Travel Pass. The paddle steamer Bluemlisalp (built 1906, restored 1992) is a particular highlight. Stop at Spiez or Oberhofen for their lakeside castles. Board at Thun Boat Station (Schiffsstation), a 10-minute walk from the train station along the Aare.

3. Walk the Obere Hauptgasse (Rooftop Shopping Street)

The Obere Hauptgasse is Thun's most distinctive feature and one of the most unusual streets in Switzerland. The buildings lining this medieval street have shops on two levels: at ground level, and on a raised terrace that functions as a pedestrian walkway running along the rooftops of the lower shops. You walk along a continuous elevated pathway at what would normally be second-floor level, with shops and cafes built into the roofline on either side, while below you another level of shops faces the street. This architectural curiosity dates to the Middle Ages and exists nowhere else in Switzerland in this form. Free, always accessible.

4. Stroll Through the Old Town and Along the Aare

Thun's compact Old Town clusters around the castle hill and along both banks of the River Aare. Key highlights include the Town Hall Square (Rathausplatz) with its painted facades, the covered wooden bridge (Obere Schleuse), the medieval towers along the river, and the 14th-century Town Church (Stadtkirche). The Aare loop walk -- following the turquoise-blue river from the lake outlet through the Old Town and back along the opposite bank -- takes approximately 45 minutes and is one of the most pleasant urban walks in Switzerland. Free.

5. Relax at Schadau Park and Castle

Schadau Park is a beautifully maintained lakeside park at the point where the Aare exits Lake Thun. The neo-Gothic Schadau Castle (1852) sits within the park and houses the Swiss Gastronomy Museum (free entry). The park itself offers expansive lawns, old trees, and -- the main attraction -- an unobstructed view across Lake Thun to the Bernese Alps, with the Niesen pyramid and Stockhorn ridgeline forming a dramatic backdrop. In summer, the adjacent Strandbad (public swimming area) provides lake access. The park is free and open year-round, a 15-minute walk from the train station.

History & Culture

Thun's strategic position -- at the point where the River Aare leaves Lake Thun and flows north toward Bern -- has made it a settlement of significance since at least the early Middle Ages. The city received its charter in 1264, and the Zahringen dynasty constructed the castle keep around 1190 to control the gateway to the Oberland valleys.

Throughout the medieval and early modern periods, Thun served as the military and administrative hub of the Bernese Oberland. The covered wooden bridges spanning the Aare, the fortified towers, and the tiered Obere Hauptgasse all date from this era of strategic importance. When the Bernese Republic expanded its territory southward into the Oberland, Thun was its forward operating base.

In the 19th century, Thun became an important military town. The Swiss army established barracks and training grounds here, and the Thun military tradition continues today with the army's logistics center. The town also became a center for pottery and ceramics -- Thuner Majolika (Thun ceramics) with their distinctive folk-art designs remain a popular Swiss souvenir and are still produced locally.

Today, Thun balances its medieval heritage with the energy of a modern regional center. The town's cultural highlight is the Thunerseespiele, an open-air musical theater performed on a floating stage on Lake Thun every summer (July-August), drawing audiences of up to 100,000 over the season. The production changes annually and features elaborate sets extending out over the lake.

Frequently Asked Questions

Is Thun worth visiting?

Yes, Thun is one of the most underrated destinations in the Bernese Oberland. It offers a genuine Swiss small-town experience with a magnificent castle, unique rooftop shopping street, and stunning lakefront setting -- without the tourist crowds and high prices of Interlaken. For travelers who enjoy authentic Old Towns and want a quieter, cheaper base for exploring the Jungfrau region, Thun is an excellent choice.

How many days do you need in Thun?

One full day is enough to see the castle, Obere Hauptgasse, Old Town, and take a lake cruise. However, ch.tours recommends two nights if you want to use Thun as a base for day trips to Interlaken, Jungfraujoch, or other Oberland destinations. As a half-day stop en route between Bern and Interlaken, allow at least 3-4 hours.

How do you get to Thun from Zurich?

Take a direct IC train from Zurich HB to Thun. Trains depart every 30 minutes and the journey takes 1 hour 20 minutes. A second-class ticket costs CHF 50 (free with Swiss Travel Pass). No changes needed -- it is a single direct train.

What is the best time to visit Thun?

May to September offers the best combination of warm weather, lake activities, and full boat service. July and August bring the Thunerseespiele open-air theater. The Christmas market in late November to December is atmospheric. Avoid November -- the fog can linger at lake level for days.

Is the Swiss Travel Pass valid in Thun?

Yes, the Swiss Travel Pass covers all trains to and from Thun, all city buses, and all BLS boats on Lake Thun. The boat cruise from Thun to Interlaken (normally CHF 62 return) is completely free with the Swiss Travel Pass, making it one of the best-value boat experiences in Switzerland.

Is Thun cheaper than Interlaken?

Yes, significantly. Hotel prices in Thun are typically 30-50% lower than comparable accommodation in Interlaken. Restaurant prices are also lower, and the town feels less oriented toward mass tourism. Since the train from Thun to Interlaken takes just 30 minutes (free with Swiss Travel Pass), ch.tours considers Thun one of the smartest base choices in the Bernese Oberland for budget-conscious travelers.

Can you swim in Lake Thun?

Yes, Lake Thun has excellent swimming from June to September. The Strandbad Thun (CHF 7 adults, 2026 prices) is the main public beach with facilities. Several free public access points exist along the lakeshore. The water temperature reaches 18-22°C in summer. The water is clean and safe -- Lake Thun is regularly tested and meets Swiss bathing water standards.

What is the Obere Hauptgasse?

The Obere Hauptgasse is Thun's most distinctive architectural feature -- a medieval shopping street where the pedestrian walkway runs along the rooftops of the ground-floor shops. You walk at second-floor level with shops built into the roof line on either side, while a normal street with additional shops exists below. This two-level arrangement is unique in Switzerland and dates to the Middle Ages.

Can you visit Thun as a day trip from Bern?

Yes, Thun is one of the easiest and most rewarding day trips from Bern. The train takes just 20 minutes, runs every 15 minutes, and costs CHF 12 (free with Swiss Travel Pass). You can comfortably visit the castle, walk the Old Town, stroll the Obere Hauptgasse, and take a 1-hour lake cruise before returning to Bern.

Where is the best view of the Alps from Thun?

The best mountain views within the town are from the Thun Castle rooftop platform (CHF 12 entry) and from Schadau Park (free). On clear days, the Eiger, Monch, and Jungfrau are visible to the south beyond the lake. For an elevated panorama, take the Stockhorn cable car from nearby Erlenbach (2,190 m summit, CHF 62 return).

Is there a Christmas market in Thun?

Yes, Thun hosts an atmospheric Christmas market in the Old Town (Rathausplatz and surrounding streets) from late November to 23 December. Approximately 50 stalls sell handmade crafts, local food, and mulled wine. The market is smaller and less crowded than Bern's markets, with a more intimate local atmosphere. Open daily from 10:00 to 20:00 (weekdays), 10:00 to 18:00 (Sundays).

Is there parking in Thun?

Yes, several parking garages are available near the center. The Grabengut parking garage (near the station) charges approximately CHF 2.50 per hour / CHF 20 per day (2026 prices). The Rathaus parking garage serves the Old Town. However, ch.tours recommends arriving by train if possible -- Thun is excellently connected by rail, and the Old Town is largely car-free.

Insider Tips from Locals

1. The castle at golden hour: Visit Thun Castle in the late afternoon (16:00-17:00) when the day-trip crowds have thinned. The rooftop platform faces southeast, catching warm late-afternoon light on the Bernese Alps. The combination of the medieval towers in the foreground and the snow-capped peaks behind is the defining photograph of Thun.

2. Swim the Aare: On hot summer days, locals float down the Aare river through the Old Town -- it is a beloved Thun tradition. Enter at the designated swimming area above the Scherzlig weir and exit at the marked exit points downstream. The water is cold (15-20°C) and the current swift. Only for confident swimmers. Free.

3. Saturday market on Rathausplatz: Every Saturday morning (07:00-12:00) the Rathausplatz hosts a farmers' market with local cheeses, breads, Valaisan dried meats, fruits, and seasonal produce. Arrive before 09:30 for the best selection. The market runs year-round.

4. Break your Interlaken journey: If traveling from Zurich or Bern to Interlaken, the IC train stops in Thun. Get off, spend 3-4 hours exploring the castle and Old Town, then catch a later train onward. Your ticket or Swiss Travel Pass covers this stop without extra cost (within the same day).

5. The Seestrasse lakefront promenade: Walk south from Schadau Park along the Seestrasse for 20 minutes to reach a series of quiet lakefront parks and swimming spots. In summer evenings, the promenade is popular for sunset walks with views across the lake to the Niesen.

6. Oberhofen Castle by boat: Instead of the bus, take the BLS boat from Thun to Oberhofen Castle (20 minutes, free with Swiss Travel Pass). The approach from the lake gives the most spectacular view of this fairy-tale castle -- photograph it from the boat before docking. Combine with a walk back along the lakeside path (4 km, flat, 1 hour) to return to Thun on foot.

7. Thun as your Oberland base: If you are exploring the Jungfrau region on a budget, consider staying in Thun rather than Interlaken. A CHF 120 hotel room in Thun offers the same train access (30 minutes to Interlaken, from where all mountain railways depart) but at roughly half the price of Interlaken accommodation. The Swiss Travel Pass makes the commute free.
