Mirror-like lake waters
2-day, 1-night travel guide to Spiez, Switzerland
📍Location: Canton of Bern, Switzerland, on the southern shore of Lake Thun. Recognized as one of the most beautiful lakeside towns, backed by the pyramid-shaped Mount Niesen, vineyards, and snow-capped mountains. The core highlights are the castle, lake views, lakeside promenade, and light hiking in the vineyards. It is 20 minutes by train from Interlaken and 10 minutes from Thun. Perfect for a slow-paced vacation and avoiding the crowds in Interlaken.
⚠️Key transportation note: The town is entirely walkable, no public transport needed. For travel outside the town, rely on trains and Lake Thun cruises. We highly recommend the Swiss Travel Pass, which covers regional trains, cruises, and free admission to Spiez Castle.
Best season: May–October (cruises are operating, lake views are at their best). Flowers bloom in May–June; golden autumn vineyards in September–October. Cruises stop in winter, which is better suited for train and snow-capped mountain routes.

To Mount Niesen: 5-minute train from Spiez to Mülenen, then transfer to the Niesenbahn funicular.
Cruises: The pier is right below the castle. Two main routes: Spiez ↔ Thun / Interlaken.
Two main 2-day itineraries: Pure town & lake cruise version / Lake view + Mount Niesen light hiking version.
✅Itinerary A | Classic relaxed version (in-depth town tour + Lake Thun cruise + Thun old town; best suited for public transport/pass holders)
Suitable for vacations, photography, and those who don't like hiking. This is the top choice for most people for a 2-day trip.
Day 1: Arrive in Spiez > Train station panoramic view > Castle > Lakeside promenade > Lakeside sunset. Stay in Spiez.
Arrive at Spiez train station by train at noon. The viewing platform outside the station is the first must-visit spot, offering a high-point overlook of the whole town, lake, and Mount Niesen—a classic panoramic photo spot.
Walk downhill to the old town and Spiez Castle: Visit the museum, climb the tower for overhead shots of red roofs + lake + snow-capped mountains. The gardens are free to explore.
Walk along the flower-lined lakeside promenade to the sailing marina and Lido beach. Stroll on the lakeside lawn and wander through the town streets.
Wait for the sunset by the lake in the evening. The sunset over the castle and the light reflecting on the lake is the core Spiez experience.
Dinner at a lakeside restaurant featuring lake fish/Rösti. Stay in town.
Logic: The first day is purely for walking and slowly exploring the town's highlights without rushing for boats, ensuring the best sunset experience.
Day 2: Lake Thun cruise > Explore Thun old town > Return / Return to Spiez for vineyard hiking.
Take a morning cruise from the pier to Thun (free with pass, choose the open-air second deck). The view looking back at Spiez Castle from the water is the best. The 1-hour cruise passes vineyards and small castles along the shore.
Disembark in Thun, explore the old town, Thun Castle, and the Aare River old streets. Have lunch in Thun.
Two return options:
Take a 10-minute train back to Spiez. In the afternoon, do the 2-hour gentle vineyard hiking loop on the hill behind the town for overhead lake views from the terraces, and stop by a local winery for a tasting.
Continue by train directly from Thun to Bern/Interlaken for your next destination.
If you don't want to go to Thun: On Day 2, take a cruise to Interlaken West instead, then return by train.
✅Itinerary B | Advanced light hiking version (Spiez + Mount Niesen pyramid mountain, mountain & lake combo)
Suitable for those who love mountain views and want an upgraded landscape experience.
Day 1: Same as Itinerary A: Train station viewing platform > Castle > Lakeside promenade > Sunset. Stay in Spiez.
Day 2: Spiez > Mülenen > Mount Niesen funicular to the summit, panoramic mountain views. Return/back to the lake in the afternoon.
Take a short 5-minute train from Spiez to Mülenen in the morning, then transfer to the Niesen funicular to Niesen Kulm (2,362m, pyramid mountain, overlooking the entire Lake Thun + Bernese Oberland mountains).
Rest at the summit restaurant and take short walks for views; the scenery is very expansive. If you don't want to take the funicular the whole way, you can hike in sections.
Take the funicular down to Mülenen in the afternoon, train back to Spiez, then continue your trip by cruise/train.
Note: Mount Niesen has seasonal operations, check opening times in advance. Not recommended for pure leisure; Itinerary A is better suited for a 2-day trip.
✅Alternative Itinerary C | Low-intensity, pure town relaxation version
Day 1: Arrival, train station, castle, relaxing picnic by the lake, sunset.
Day 2: Slow walk on the vineyard trail, visit the small church, have coffee at the pier. No boats, stay in town. Return by train in the afternoon.
Top choice for families, leisure, and relaxing vacations.
✅Alternative Itinerary D | Connecting with Interlaken
Day 1: Train from Interlaken to Spiez, castle + lakeside sunset. Stay in Spiez.
Day 2: Cruise back to Interlaken West, explore Interlaken/Lake Brienz. Suitable as a stopover for Jungfrau trips.
⚠️Key tips to avoid pitfalls
Spiez Castle is closed on Mondays, so don't plan a visit for Monday morning. The gardens remain accessible.
Cruises operate from mid-April to October and stop in winter. Check schedules and last boat times on SBB Mobile in advance (approx. 6:10 PM to Thun, 5:30 PM to Interlaken West).
It's windy by the lake, and there's a significant temperature difference between day and night. Bring a windbreaker even in summer. Weather in the lake region changes quickly.
Many shops and supermarkets are closed on Sundays, so prepare light meals in advance. There is no food delivery in Switzerland, and costs are relatively high.
Many private residences in residential areas prohibit photography. Stick to public paths, the castle, and the lakeside.
Don't try to cram a deep tour of both Jungfrau and Spiez into two days; it will be very rushed. Prioritize one as your main itinerary and do the other as a short day trip.
The vineyard trail is a gentle, easy hike (2 hours, no difficulty), not mountain climbing. Mount Niesen is the actual mountain climbing route.
The walk from the train station to the pier is all downhill, which can be tiring with large luggage. If driving in peak season, parking by the lake is limited; prioritize the station parking garage.
