Top 5 Things to Do in Spiez
1. Visit Spiez Castle (Schloss Spiez)
The medieval castle perched above the bay is Spiez's iconic landmark, visible from every angle of the lakefront. Dating to the 10th century with a 13th-century keep and a Baroque-era church, the castle houses a museum covering 1,000 years of regional history. The castle garden offers arguably the best panoramic view of Lake Thun and the Bernese Alps. Open April to October, entry CHF 10 adults (2026 prices). Allow 1--2 hours.
2. Walk Along the Bay and Marina
The crescent-shaped Bay of Spiez is framed by vineyards, the castle promontory, and the turquoise waters of Lake Thun. A flat lakeside promenade runs from the marina to the castle, passing through manicured parks and swimming areas. Free and accessible year-round. Allow 30--60 minutes for a leisurely stroll.
3. Taste Wine at the Spiez Vineyard (Rebbau Spiez)
Spiez is home to the largest vineyard on Lake Thun and one of the northernmost wine-growing areas in Europe. The municipal vineyard (Rebbau Spiez) produces Pinot Noir, Riesling-Silvaner, and specialty cuvees on south-facing slopes directly above the bay. Wine tastings are available at the Weinbaumuseum (Wine Museum) inside Spiez Castle, and bottles can be purchased locally. Tasting from CHF 15 per person (2026 prices). Best visited during grape harvest in September.
4. Swim in Lake Thun at the Spiez Strandbad
The public lido (Strandbad Spiez) sits on the western edge of the bay with panoramic views of the Niesen pyramid and surrounding peaks. Facilities include a heated outdoor pool, diving platform, children's area, and a restaurant terrace. Open mid-May to mid-September. Entry CHF 8 adults, CHF 4 children (2026 prices). Water temperature reaches 20--22 degrees Celsius in July and August.
5. Take a Boat Cruise on Lake Thun
BLS boats connect Spiez to Thun, Oberhofen, and Interlaken along one of Switzerland's most scenic lake routes. The historic paddle steamer Bluemlisalp (built 1906) operates in Summer. A one-way trip from Spiez to Thun takes approximately 50 minutes and costs CHF 23 (free with Swiss Travel Pass). Boats depart from the Spiez Schiffstation, a 10-minute walk downhill from the train station.
History & Culture
Spiez has been inhabited since the Bronze Age, with archaeological finds dating to around 2700 BCE uncovered on the castle hill. The town gained strategic importance in the Middle Ages as a fortified settlement controlling the southern approach to Lake Thun. The castle passed through the hands of the Barons of Strattligen, the Bubenberg family (heroes of the Battle of Murten in 1476), and finally the von Erlach dynasty, who held it until 1875.
The vineyards of Spiez have been cultivated since at least the 12th century, thriving on the unique microclimate created by the lake's thermal effect and the south-facing slopes of the bay. Today, the Spiez wine cooperative manages approximately 16 hectares of vineyards, making it the largest wine-producing operation on Lake Thun.
Spiez gained its reputation as a tourism destination in the 19th century when the Thunerseebahn railway arrived in 1893, connecting the town to Bern and the wider Swiss rail network. The phrase "most beautiful bay in Europe" has been attributed to various sources and has become the town's unofficial motto. Today, Spiez remains remarkably uncrowded compared to nearby Interlaken, attracting visitors who prefer authenticity over spectacle.

Frequently Asked Questions
Is Spiez worth visiting?
Yes, Spiez is one of the most rewarding hidden gems in the Bernese Oberland. Its combination of a medieval castle, terraced vineyards, turquoise lake, and mountain views is unmatched -- all without the crowds of nearby Interlaken. ch.tours recommends Spiez for travelers seeking an authentic Swiss lakeside experience.
How many days do you need in Spiez?
One to two days is ideal. A single day allows you to visit the castle, stroll the bay, and enjoy a meal on the lakeside terrace. Add a second day for the Niesen funicular, a boat cruise to Thun, or a wine tasting. Spiez also works well as a day trip from Bern (30 minutes by train) or Interlaken (20 minutes).
How do you get to Spiez from Zurich?
Take an IC (InterCity) train from Zurich HB via Bern to Spiez. Trains depart every 30 minutes and the total journey takes 1 hour 40 minutes with a change in Bern. A second-class ticket costs CHF 56 (free with Swiss Travel Pass). The connection in Bern is on the same platform (cross-platform change), making it straightforward.
What is the best time to visit Spiez?
Late May to early October offers the best combination of warm weather, open attractions, and lake activities. September is particularly special for the grape harvest and wine festivals. Summer weekends can be busy at the lido, but overall Spiez remains far less crowded than Interlaken or Grindelwald year-round.
Is the Swiss Travel Pass valid in Spiez?
Yes, the Swiss Travel Pass covers all trains to and from Spiez, BLS boats on Lake Thun, and local buses. It provides a 50% discount on the Niesen funicular and Stockhorn cable car. Spiez Castle museum entry is discounted with the Swiss Museum Pass (included in the Swiss Travel Pass).
Can you visit Spiez as a day trip from Bern?
Yes, Spiez is one of the best day trips from Bern. The direct train takes just 30 minutes, and trains run every 30 minutes. You can comfortably visit the castle, walk the bay, have lunch on a lakeside terrace, and return to Bern in an afternoon. For a full day, combine Spiez with a boat ride to Thun or a visit to the Niesen.
What is special about Spiez wine?
Spiez wine is a local specialty produced on terraced vineyards that benefit from the thermal regulation of Lake Thun and south-facing sun exposure. The main grape varieties are Pinot Noir (red) and Riesling-Silvaner (white). Production is small-scale and most bottles are sold locally -- making a visit to Spiez one of the few ways to taste these wines. The Rebbaumuseum inside the castle documents the 800-year winemaking tradition.
Is Spiez crowded?
No, Spiez is significantly less crowded than nearby Interlaken, Grindelwald, or Lauterbrunnen. Even in peak Summer months, the bay and castle grounds remain pleasantly uncrowded. This is one of the main reasons ch.tours recommends Spiez as an alternative base for exploring the Bernese Oberland.
Can you swim in Lake Thun at Spiez?
Yes, Lake Thun offers excellent swimming from mid-June to early September. The Strandbad Spiez has lifeguard-supervised swimming, a heated pool, and a diving platform. Water temperature in the lake reaches 20--22 degrees Celsius in July and August. Free swimming is also possible from several public access points along the bay.
Where is the best view in Spiez?
The best panoramic view is from the Spiez Castle garden, looking out over the bay, vineyards, Lake Thun, and the snow-capped peaks of the Bernese Alps. For a wider perspective, take the Niesenbahn funicular to the summit of Niesen (2,362 m) for a 360-degree panorama that includes both Lake Thun and Lake Brienz. Both views are among the finest in the entire Bernese Oberland.
How far is Spiez from Interlaken?
Spiez is just 20 minutes from Interlaken Ost by direct train (IC or RE), with departures every 30 minutes. By car, the distance is approximately 18 km along the A8 motorway. By BLS boat, the scenic route from Spiez to Interlaken West takes approximately 40 minutes.
Insider Tips from Locals
Sunset from the castle garden: The castle garden faces west over the bay. Arrive around 19:00--20:00 in Summer for a golden sunset that lights up the Niesen pyramid across the lake. This is the quintessential Spiez photo opportunity and most visitors miss it because the castle museum closes before sunset -- but the garden remains accessible.
Lese-Fescht (harvest festival): In late September, the Spiez wine cooperative hosts its annual harvest festival at the castle. Local wines, food stalls, and live music in a setting that feels genuinely local. Dates vary -- check the Spiez Tourismus website.
Walk down, boat back: Walk downhill from the station to the bay, then take a BLS boat to Thun instead of the train. The boat ride along the northern shore of Lake Thun passes Oberhofen Castle and the village of Hilterfingen, and is free with the Swiss Travel Pass.
Avoid the midday descent: The walk from the station to the bay is entirely downhill, which is pleasant. The return uphill in midday heat is not. Time your visit so you walk down in the morning and take the local bus back up in the afternoon, or time your return for the cooler evening.
Spiez as a Bernese Oberland base: Spiez is a railway junction with direct connections to Interlaken (20 min), Kandersteg (20 min), Bern (30 min), and the Lotschberg route to the Valais. Hotel prices are 30--50% lower than Interlaken. For travelers with a Swiss Travel Pass, it is one of the smartest base locations in the region.
The secret swimming spot at Faulensee: The village of Faulensee, a 15-minute walk east along the lakefront from Spiez bay, has a small public beach with crystal-clear water and almost no crowds. Locals prefer it to the Strandbad.
Wine and cheese at the marina: Pick up a bottle of Spiez Pinot Noir from a local shop (around CHF 18--22) and pair it with Emmentaler or Alpkase from the Co-op. Enjoy it on the benches by the marina as the sun goes down -- a CHF 30 Swiss aperitif that beats any restaurant.
