Private Sightseeing Boat Trip on Lake Thun, Interlaken
Lake Thun is at its best from the water, when the mountain views open up and the shoreline slips past without road noise or tour-bus crowds. This private cruise leaves from Beir Säge in Sigriswil and heads toward Schloss Spiez and Merligen before finding a good place to watch the sunset.
I like the private setting, which lets your group enjoy the hour at its own pace, and the fact that you do not need to handle the boat yourself. Pizza with a lake-and-mountain view is another nice touch. The main consideration is the short one-hour duration, plus the non-refundable booking policy if your plans change.
Key points to know before you book

- Private Lake Thun cruise: Only your group joins the boat, so you avoid a crowded public excursion.
- Sunset-focused route: The captain cruises until finding a pleasant spot for sunset views.
- Schloss Spiez and Merligen: These are the named stops along the route and give the trip a clear sense of place.
- Boat capacity varies by description: The boat can carry up to 12 people, while the experience is also presented as especially suitable for groups of up to six.
- Pizza on the lake: You can enjoy food with the mountain backdrop rather than in a busy restaurant.
- Captain Chris: When he is at the helm, expect a friendly captain and a clean, well-maintained boat.
Why a private hour on Lake Thun works

A one-hour boat ride can sound brief. On Lake Thun, though, it gives you enough time to enjoy the setting without turning the outing into a half-day commitment.
You meet at Beir Säge, in Sigriswil, then leave the dock with your own group. The boat does the work. You can sit back, watch the shoreline, and keep your attention on the lake rather than on navigation or transport connections.
That privacy is the main reason to choose this trip over a standard public boat service. You are not sharing the outing with a large crowd or trying to find a seat with the best view. If you are traveling with family, friends, or a small celebration group, the private format makes the hour feel more personal.
I also like the timing. The boat searches for a suitable place to watch the sunset instead of simply following a fixed sightseeing loop. The exact sunset view depends on the weather and the captain’s route, but the basic idea is simple: get out onto the water when the light is changing, then pause somewhere scenic.
The short duration also suits an evening when you have other plans. You can fit it around dinner, a visit to Interlaken, or time spent around Lake Thun. Just do not book it expecting a full lake crossing or a long sightseeing cruise. This is a compact scenic outing.

Leaving Sigriswil for Schloss Spiez

The meeting point is Beir Säge, 3658 Sigriswil, Switzerland. That detail matters because the experience does not begin in central Interlaken itself. Check your route to Sigriswil carefully before booking, especially if you are relying on public transport.
Once aboard, the first named stop is Schloss Spiez. The castle gives the cruise a useful historical and visual marker. From the water, you get a different view than you would from a road or walking path. The lake, castle setting, and surrounding mountains create the sort of scene that works best at a gentle pace.
The itinerary does not promise a castle tour or a long stop ashore. You should think of Schloss Spiez as part of the boat route, not as a separate guided visit inside the castle. That distinction keeps expectations realistic. The value comes from seeing the area from the lake and including a notable shoreline sight in the cruise.
Because the tour lasts about an hour, the time at each point may be limited. If you want a detailed visit to Schloss Spiez, you will need to arrange that separately. The boat trip gives you a pleasant look at the setting, but it is not a substitute for a full castle visit.
Merligen and the changing lake views
Merligen is the second named stop. Like Schloss Spiez, it helps define the route and gives you another section of Lake Thun to see from the boat.
The appeal here is the change in view as the boat moves along the shoreline. You are not simply looking at one fixed panorama from the dock. The angle shifts as the captain steers, which can make the surrounding mountains and water feel different from one moment to the next.
The provided details do not specify a walking tour, a landing, or a set amount of time at Merligen. Plan on seeing it as part of the cruise rather than treating it as a long stop. If you want to explore Merligen on foot, make that a separate plan.
This is one place where the private format may help. The captain can focus on your group, handle the boat, and keep the experience relaxed. You are not expected to navigate or operate anything yourself. That makes the trip easy for people who simply want to sit down, take photos, and enjoy the view.
Sunset, pizza, and the practical pleasure of staying aboard

The sunset element is the most distinctive part of the outing. The boat continues along Lake Thun until the captain finds a nice place to watch the sun go down. Since sunset depends on clouds, timing, and visibility, you should treat this as a weather-sensitive plan rather than a guaranteed dramatic show.
Pizza adds a casual touch. Instead of building the evening around a busy restaurant, you can eat on the boat with the lake and mountains around you. That is especially handy for a group that wants food and sightseeing in the same hour.
The available details do not explain the pizza menu, serving size, or whether dietary requests can be accommodated. Ask the provider before booking if those details matter to you. The food is best understood as a pleasant part of the outing, not as a full restaurant experience.
I would also keep the meal expectations simple. A one-hour cruise leaves little time for a long, leisurely dinner. The charm is the combination of a relaxed boat ride, a casual meal, and sunset scenery.

Captain Chris and the boat itself

Captain Chris is named in the available tour information and is described as friendly and nice. The boat has also been described as clean and well maintained. Those details matter more on a private trip than on a quick public ferry ride because you spend the entire experience in the same small setting.
You do not need boating experience. The captain takes care of the boat while you focus on Lake Thun. That makes this a good choice if you want a water experience without learning controls, following instructions, or worrying about the route.
The boat can transport up to 12 people. At the same time, the experience is promoted as especially suitable for groups of up to six. I would read that as a comfort tip rather than a hard contradiction: larger groups may fit, but six or fewer may have a more spacious private-boat experience.
If your party is larger than six, confirm the exact boat arrangement before paying. The capacity is stated as up to 12, but the comfort level, seating layout, and food setup are not described in detail.
Is $263.87 per person good value?

At $263.87 per person, this is not a cheap way to get on Lake Thun. The price needs to be judged against the private format, not compared directly with a standard public boat fare.
For a small group, the cost may make sense if privacy is important. You are paying for an exclusive boat, a captain, a planned scenic route, and the chance to stop for sunset without sharing the experience with strangers. If pizza is part of your plan, you also combine a meal with the cruise rather than paying for two separate activities.
For one or two people, the price is harder to justify unless you place a high value on privacy. A public boat or shore-based sunset plan may cost less, though it would not offer the same private setting.
The value improves when you divide the experience across a group, but check the final group capacity and pricing before booking. The supplied details list both a maximum of 12 people and a preferred group size of up to six, so the best fit may be a smaller private party.
Who will enjoy this cruise most

I would recommend this experience to people who want a calm, scenic hour rather than a packed sightseeing schedule.
It suits:
- Couples who want a private sunset setting
- Families who prefer their own boat
- Friends sharing a casual pizza outing
- Small groups celebrating a special evening
- People who want lake views without operating a boat
- Visitors staying near Lake Thun who can reach Sigriswil
It may not suit you if you want a long cruise, a detailed castle tour, or a flexible cancellation policy. The experience requires good weather, and the booking is non-refundable and cannot be changed for any reason. If poor weather forces the operator to cancel, you are offered another date or a full refund, but that protection does not apply if you change your own plans.
The activity is offered in English, and most people can participate. It is near public transportation, but the exact connection details are not provided, so allow time to reach Beir Säge.
What I would check before booking

First, confirm the meeting point and route from your accommodation. Sigriswil is the start and end point, not simply a name for the wider Interlaken area.
Next, confirm the group size. The boat can carry up to 12 people, but the experience is also described as ideal for groups of up to six. If you have more than six in your party, ask how seating and pizza service will work.
I would also confirm the food details if pizza is important to your decision. The experience includes the chance to enjoy pizza, but no menu, portion, or dietary information is supplied.
Finally, watch the forecast. This is a weather-dependent boat trip, and sunset views are naturally tied to conditions. A clear evening may give you the best scenery, while clouds can soften the light or block the sunset.
Should you book the Lake Thun boat trip?
Book it if you want a private, easygoing evening on the water and value a personal setting more than a low price. The combination of a clean boat, a friendly captain such as Chris, Schloss Spiez, Merligen, pizza, and sunset views makes the hour feel more special than a basic transfer.
Skip it if you need a flexible booking, want a long cruise, or are mainly looking for the cheapest way to see Lake Thun. For the right small group, though, this is a simple and appealing way to trade crowded sightseeing for a quiet hour on the lake.
