Blausee and Castle Spiez and Lake Thun Sightseeing Tour Private

Blue water, fast access, and quiet time to look around. This private 5-hour sightseeing plan takes you from Interlaken into the Lake Thun area with an extra-scenic drive, then gives you real time at Blausee so it does not feel like a drive-by photo stop.

I love that you get included entry for the lake area, so you can wander the park at your own pace instead of rushing through. I also like that the day is built for comfort, with pickup arranged from your location and a car route chosen to cut down time and hassle.

The main thing to think about is that this is short on purpose, so if you want lots of time at every stop, you will feel a little time pressure. Also, the glass-bottom boat depends on season and local conditions, so it is not a guarantee year-round.

Key highlights you will feel right away

• Private scenic route with fewer transfers than public transport
• Blausee park entry included, so you can explore freely
• Summer-only glass-bottom boat, sometimes with a queue and limited ride sizes
• Spiez return stop for the Ghost Castle when timing allows
• Optional lake swim at Faulensee, if you bring a towel and are comfortable with cold water
• WhatsApp coordination can keep the day moving smoothly

From Interlaken to Blausee, the drive is part of the payoff

This tour is not just about reaching Blausee. It is about getting there on roads that treat you like a visitor, not a bus passenger.

On the way, you pass through a chain of Lake Thun viewpoints. You start with Därligen, then move through Krattigen and Aeschi bei Spiez, where the tour focuses on higher angles back over the lower lake. Reichenbach is a small-town pause, then you go past Frutigen under an old train bridge, which adds a little texture beyond just the water.

Even though these are brief passes, the effect is real: you spend less mental energy figuring out routes and transfers, and more attention on what Switzerland looks like from a moving car at lake height. If you like scenic drives, this is where the day earns its keep.

A practical note: some spots are marked as pass by with short time windows. So if you are the type who wants to hop out constantly, plan on saving your biggest walking time for Blausee itself, not the roadside viewpoints.

Private transport options, eco choices, and why vehicle size matters

You get private transportation, and the vehicle you select changes how the day feels.

• Option A uses a 2-door eco car with alcohol fuel made from grass. The pitch is CO2 neutral and clean tech support, and if you are traveling light, it is often the easiest and cheapest private option.
• Option B is a 4-door eco car, still eco-focused, but with more everyday practicality for getting in and out.
• Option C is an 8-person eco van, which is best if you are traveling as a larger group and want everyone together without splitting up.

Why this matters: pickup is included, but you only get the pickup if the area is accessible by car without restrictions. A smaller vehicle can sometimes mean slightly more careful timing and meeting points, while the van option can feel easier for groups and families.

Communication is also part of the “private” experience. The operator uses WhatsApp and may use live location sharing for coordination. If you want the day to run smoothly, keep your phone charged and ready.

Blausee-Mitholz: the park time that makes this tour feel worth it

Your main stop is Blausee, at Blausee-Mitholz. You get about 1 hour 20 minutes on site, and the ticket is included. That time window is short enough to fit the rest of the day, but long enough to actually enjoy the setting instead of just snapping one picture and leaving.

What makes Blausee special here is the way the park experience is structured. You are given freedom to explore, with nature trails, a restaurant on site, and a children’s playground if that matters for your group.

In summer months, you may also be able to take the glass-bottom boat, rowed by a storytelling guide. Two things to know upfront:

1. The boat can accommodate groups up to 8 people per ride.
2. There might be a queue, and the boat is not always guaranteed due to special events or off-season timing.

Translation: if you care about the glass-bottom part, try to arrive ready to go in and be flexible with timing. If the boat is busy, the lake and forest views are still the core attraction, and you will not feel like you wasted your visit.

The Dragon Cave walking track at Blausee

One of the more memorable details is the included guidance about a hidden track to the Dragon Cave. The walk is nature-path style, and it needs normal fitness and sport shoes with grip. The operator also asks you to slow down, watch each step, and avoid running or jumping.

They also add a very specific rule: do not touch the eggs. If you are traveling with kids, this is a real consideration. “Guard the children” is not a vague suggestion, it is part of the safety instructions.

So if your group is comfortable with short uphill walking and careful footing, this is the kind of detail that can turn Blausee from a pretty lake stop into a small adventure.

How the Ghost Castle and Faulensee fit into your day

After Blausee, the return leg adds two bonus stops, both about different flavors of Switzerland.

Spiez and the Ghost Castle stop

In Spiez, you have about 15 minutes. The tour plans an alternate route on the way back to allow more scenic viewing, and if there is time, you can stop at the Ghost Castle.

Fifteen minutes is brief. This is not a long castle tour day. But it can still be a fun break if you want a dramatic photo moment, a quick look over the lake, and a story-type stop that feels different from just walking trails.

Faulensee: quick swim option

Then there is Faulensee, another 15-minute stop. This is the stop to treat like optional downtime, especially if you bring your swimsuit and towel.

You can take a quick swim if you want, and the operator is upfront about the reality: it is cold water. They specifically note you should be able to swim and you should have no heart problems before doing it. If you want the swim option, tell the guide before or at pickup so it can be factored into the timing.

This is a nice add-on if you like water breaks, but it is also a good one to skip if your only goal is sightseeing photos and calm walking.

What you should pack (and what you can skip)

This is the kind of tour where what you bring changes how much you enjoy it.

Bring:

• Sport shoes for the Dragon Cave track on a nature path
• A swimsuit and towel if you want the Faulensee swim
• Your phone charged for WhatsApp coordination
• Layers, even in warmer months, since lakeside temps can feel cooler

You can skip:

• Bottled water, since it is not listed as included
• A coffee plan at the lake, since coffee or tea is not included and lunch or snacks at the Blausee restaurant are also not included

If you are thinking about hunger, treat this as a “snack or meal planning” day. You may pass enough scenery that you feel energized, but you still need fuel.

The timing trick: when to go so the day stays relaxed

The operator strongly suggests going early if you can. In summer season, it is less hot and the chance of waiting in line is reduced.

That matters most for the glass-bottom boat. If you show up later, you might spend your limited Blausee time watching a queue instead of enjoying the lake. Going earlier also helps if your group wants to include the walking track and still enjoy views without feeling rushed.

Your total time is about 5 hours, so the day is designed to keep moving. If you like unhurried visits, aim for an early start and treat the short stops as scenic breaks rather than full-on exploration zones.

Price and value: is $249.99 per person fair here?

At $249.99 per person, this is not a budget day trip. It is a private tour, and private routing costs money.

Where the value comes from:

• Private transportation with pickup included, so you avoid train-to-bus juggling
• Tickets included for the Blue Lake, Blausee area
• All toll road fees included
• An expert guide who knows hidden routes, including the Dragon Cave track
• The option of a glass-bottom boat in summer (when conditions allow)

The value argument is strongest if you hate transfers, want a scenic drive without planning, and enjoy the idea of a guide steering you to the best moments within limited time.

Where it might not be ideal:

• If you are traveling with a big group, the per-person math can feel steep compared to splitting a cheaper shared transport option
• If you prefer long museum-style time at one place, the Blausee time of about 1 hour 20 minutes might feel too short

Also, the tour is non-refundable and cannot be changed. That is important. If your calendar is flexible, this is a risk. If your dates are locked, you can treat it like a paid reservation for a very scenic half-day.

Who should book this Blausee and Spiez private tour

Book it if:

• You want private transport from Interlaken with minimal stress
• You care more about lake views, nature paths, and a guided plan than about spending half the day commuting
• You like the idea of Blausee plus a quick Spiez stop, not just one single attraction
• Your group can do short, careful walking with sport shoes

Skip it or plan carefully if:

• You want lots of time at each stop, especially in Spiez
• You rely on a glass-bottom boat ride as the one must-do activity, since it can have queues and may not be guaranteed depending on dates and events
• Cold-water swimming sounds like a bad bet for your comfort level, since Faulensee is an option that depends on preparation and health considerations

Should you book this tour or go on your own?

If you are deciding between DIY planning and a guided private route, the choice is simple for most people: if you want the day to feel smooth and scenic with minimal logistics, this is built for you.

You are paying for fewer transfers, included entry, and a guide who adds details like the Dragon Cave walking track and practical timing tips. And if you are a fan of Lake Thun views, the route stops along the way help the drive feel like part of the experience.

I would book it when your dates are firm, you like early starts, and you want Blausee to be the main event.

If your schedule is flexible, you are price-sensitive, or you truly want to wander with no time structure, you might find independent travel better. But for a private, well-paced half-day with tickets handled, this tour is a solid fit.
