The colour that gives Lake Brienz away
Lake Thun and Lake Brienz sit either side of Interlaken, drain the same Bernese Alps, and get compared constantly, but they don’t look alike. Brienz runs a deeper turquoise, especially between May and August when snowmelt carries fine glacial silt down the Aare and into the lake. The particles stay suspended and scatter light in a way that plain meltwater doesn’t, which is the entire reason every photo of this lake looks slightly implausible. It’s not filtered. Stand on the Giessbach terrace or the Iseltwald pier on a clear afternoon and the water really is that colour.
That said, Brienz is a smaller, quieter proposition than Lake Thun or the boat network around Lake Lucerne. There’s one town of the same name (Brienz), a scattering of villages, and four things that justify the trip: the Giessbach Falls and their funicular, the village of Iseltwald, the Ballenberg open-air museum, and the Brienzer Rothorn steam railway. None of them are close enough together to combine casually, so this guide treats the lake as a menu, not a single stop.
Giessbach Falls and the 1879 funicular
The Giessbach Falls drop roughly 500 metres down the northern shore in a series of fourteen cascades, visible from the lake boats and from Brienz itself. What makes the spot more than a waterfall photo stop is the funicular: built in 1879, it’s one of the oldest funicular railways still running in Switzerland, and it hauls visitors up a steep, wooded slope to the Grandhotel Giessbach terrace in about five minutes.
The return ticket costs around CHF 10 for adults, with Swiss Travel Pass holders riding free and Half Fare Card holders paying half. The funicular runs from roughly late April to late October; outside that window it’s closed for maintenance and the falls are only reachable on foot, which is a steep 30 to 40 minute climb.
From the top, marked trails cross behind and alongside the cascades on wooden bridges and viewing platforms. Allow 45 minutes to an hour to walk the full network at an unhurried pace. The Grandhotel terrace has a restaurant with lake views, priced for the setting: a coffee runs CHF 5 to 6, a main course CHF 28 to 40. There’s no obligation to eat there, and a packed lunch on one of the lower platforms saves the mark-up without losing the view.
Access is by lake boat from Interlaken, Brienz or Iseltwald to the Giessbach jetty, followed by the funicular. There’s no road access to the funicular’s lower station for casual parking, which keeps the site from feeling as commercialised as Mount Rigi or Mount Titlis can on a peak summer day.

Iseltwald sits on a small wooded peninsula on the lake’s southern shore, a settlement of a few hundred people with a working boat harbour and not much else in the way of infrastructure. It became disproportionately known after a Netflix series filmed a brief scene at the wooden pier jutting into the lake, and the pier now draws a queue of visitors taking the same photograph, particularly in July and August around midday.
The rest of the village is unaffected. One street back from the pier, Iseltwald is a normal lakeside hamlet with a couple of restaurants, a small grocery, and views across to the Giessbach falls on the opposite shore. Parking is limited to a small pay lot near the entrance to the village (roughly CHF 2 per hour), and it fills by mid-morning in peak season; arriving before 9am or after 5pm avoids both the parking problem and the pier queue.
Iseltwald is reachable by BLS lake boat from Interlaken Ost or Brienz, by the postbus from Interlaken, or by car via the lakeside road, which is narrow in places. Walking trails also connect the village to Giessbach along the shore, a route of about 2 to 3 hours one way that alternates between forest path and short road sections.

Ballenberg, just outside the town of Brienz, is Switzerland’s open-air museum of vernacular architecture: more than 100 original buildings relocated from across the country and reassembled across a large wooded site, organised by region. It functions as a working farm as much as a museum, with animals, demonstration crafts, and seasonal events rather than static rooms behind glass.
A full visit needs 3 to 4 hours minimum; the site covers around 66 hectares and walking between the furthest buildings takes real time, though an internal bus service (included in the ticket) cuts down the distance. Adult admission is around CHF 32, with reductions for the Swiss Travel Pass (typically 50 percent off rather than free) and for families. The museum opens from early April to late October and closes for winter, so this is not a shoulder-season fallback plan.
Ballenberg pairs awkwardly with the Giessbach side of the lake in a single day, since it sits on the opposite shore near Brienz town and the transfer by boat or bus eats into the hours needed for either site to be worth the ticket. If the itinerary is tight, pick one: Ballenberg for a rainy day with the whole family, or Giessbach and Iseltwald for a clear day focused on the water.
Brienzer Rothorn: the last regular steam railway in Switzerland
The Brienzer Rothorn Bahn is a rack railway running from Brienz station up to the 2,244-metre summit of the Brienzer Rothorn, and it’s the last mountain railway in Switzerland to run scheduled services with steam locomotives rather than diesel or electric traction. Not every departure is steam-hauled — some run on diesel locomotives to cope with demand — but the timetable marks which trains are which, and steam departures are the reason most visitors come.
The journey takes about an hour each way, climbing through forest and alpine meadow before opening onto a summit panorama that takes in the Bernese Alps, the lake below, and on a clear day as far as the Jungfrau group. A return ticket costs around CHF 96 for adults, with the Half Fare Card cutting that roughly in half and the Swiss Travel Pass giving a further discount rather than free travel, since this line sits outside full pass coverage.
The railway operates from around early June to late October, weather permitting, with the steam-specific departures concentrated in the summer months. Capacity per train is limited by the vintage rolling stock, so on clear days in July and August the early departures sell out; booking ahead or arriving at the station by mid-morning is worth doing rather than assuming a same-day seat.

There’s no direct train from Zurich to Brienz. The standard route runs Zurich HB to Interlaken Ost (about 2 hours), then changes onto the BLS lake line towards Brienz, adding roughly 20 minutes to Brienz town or a bit longer to Giessbach and Iseltwald by boat. Budget 2 hours 20 minutes to 2 hours 40 minutes each way depending on the exact destination and connection.
| From Zurich HB to | Approx. journey time | Typical one-way fare (2nd class, full fare) |
|---|---|---|
| Interlaken Ost | 2h00 | CHF 68 |
| Brienz (via Interlaken) | 2h20 | CHF 74 |
| Giessbach (train + boat) | 2h40–3h00 | CHF 78–85 |
| Iseltwald (train + boat/bus) | 2h30–2h50 | CHF 76–82 |
Fares drop by roughly half with a Half Fare Card, and the Swiss Travel Pass covers the trains and lake boats outright, though not the Giessbach funicular’s discount is only partial and the Rothorn railway gives a reduced rate rather than free travel. For a single long day out, working out whether a day pass beats point-to-point tickets is worth five minutes with the Zurich Card versus Swiss Travel Pass comparison before booking anything.
Driving is an option but not obviously a better one: the lakeside road narrows around Iseltwald, parking at Giessbach’s lower station is minimal, and a return trip is close to three hours of driving on top of whatever time is spent at the lake. For a car-based version of the region, see car rental in Switzerland for the practicalities and costs.
Given the travel time, Lake Brienz works better as an overnight add-on to a stay in Interlaken or Grindelwald than as a rushed single day from Zurich. If a full multi-day Bernese Oberland loop is on the table, the five-day summer Alps itinerary builds Brienz in alongside Lucerne and the high mountain excursions rather than treating it as an isolated trip.
Boat trips on the lake
BLS runs scheduled lake boats connecting Interlaken Ost, Iseltwald, Giessbach and Brienz from spring through autumn, with a thinner winter timetable on the Interlaken–Brienz stretch only. A one-way fare from Interlaken Ost to Giessbach runs around CHF 30, though the Swiss Travel Pass covers it in full and the Half Fare Card at 50 percent. The crossing from Iseltwald to Giessbach is short, around 20 minutes, and is the easiest way to combine both sides of the lake without doubling back through Brienz town.
For a broader look at what’s available on Swiss lake boats generally, the Lake Thun and Brienz cruises guide covers timetables and seasonal variation across both lakes side by side.

Brienz town has the most beds and the most normal price range for the region: a mid-range double room runs CHF 150 to 220 a night in summer. Iseltwald has a handful of guesthouses at similar or slightly higher rates given the smaller supply. Staying in Interlaken instead gives more choice and better onward connections to Grindelwald, Lauterbrunnen and Lake Thun, at the cost of a short additional hop to reach Brienz each day.
Eating around the lake is unremarkable and priced like the rest of the Bernese Oberland: a restaurant main runs CHF 25 to 40, a coffee CHF 4.50 to 6. Brienz town has a modest choice of cafés and lakeside restaurants; Iseltwald has two or three options right on the water. Neither location is a food destination in its own right, so for a proper meal it’s worth planning around fondue and raclette in Zurich before or after the trip rather than expecting much variety lakeside.
Practical planning: prices, seasons, timing
| Site | Season open | Typical cost (adult) | Time needed |
|---|---|---|---|
| Giessbach funicular | Late April–late October | CHF 10 return | 1–1.5 hours incl. falls walk |
| Ballenberg museum | Early April–late October | CHF 32 | 3–4 hours |
| Brienzer Rothorn Bahn | Early June–late October | CHF 96 return | 2–2.5 hours incl. summit time |
| Lake boats (per leg) | Spring–autumn, reduced winter | CHF 15–30 | 20–45 minutes |
A realistic daily budget, on top of train fares from Zurich, sits at CHF 90 to 150 per person: one attraction (funicular or Ballenberg, not both), lunch, and a boat leg or two. Adding the Rothorn steam train pushes a single day closer to CHF 200 once transport, the summit ticket and food are all counted.
The main planning trap is seasonality. All three headline attractions — the Giessbach funicular, Ballenberg and the Rothorn railway — close for winter, roughly November to March or April depending on the site, and mountain lifts across the region routinely shut for spring and autumn maintenance windows even within the nominal season. Before booking a specific date, it’s worth checking current opening dates directly rather than assuming last year’s calendar holds, a mistake covered more generally in first-time mistakes in Zurich.
Common mistakes to avoid
Trying to do Giessbach, Iseltwald, Ballenberg and the Rothorn all in one day from Zurich is the most common overreach. The lake is compact on a map but the sites are spread across both shores with boat and bus transfers between them, and each one individually needs an hour or more once travel to and from Zurich (roughly 5 hours round trip minimum) is already committed. Picking two, or one plus a boat ride, gives a day that doesn’t feel rushed.
The second mistake is assuming the Rothorn train is always steam-hauled. Diesel locomotives cover a portion of departures, particularly outside peak summer, so a visitor set on the steam experience specifically should check the day’s timetable rather than the railway’s general marketing. For a wider comparison of the region’s classic rail routes, see the Golden Pass Line guide and the Bernina Express guide, both of which cover ground Brienz doesn’t.
Lake Brienz: frequently asked questions
Is Lake Brienz worth visiting if I’ve already seen Lake Thun or Lake Lucerne?
Yes, mainly for the colour and the Giessbach Falls. Brienz’s water carries more glacial silt from the Aare than Thun’s, giving it a stronger turquoise cast, especially from May to August. The funicular up to the falls and the Ballenberg museum are not duplicated anywhere else in the region.
How do I get from Zurich to Lake Brienz in a day?
Take the train from Zurich HB to Interlaken Ost, then change onto the BLS line running along the lake to Brienz, Iseltwald or Giessbach. The full journey is about 2 hours 20 minutes each way, so allow at least 9 hours door to door if you want unhurried time at the lake.
Is the Giessbach funicular running all year?
No. The funicular typically operates from around late April to late October, closing for winter maintenance outside that window. Check the current BLS or Giessbach timetable before travelling, since exact dates shift by a few weeks each year.
How much does the Brienzer Rothorn steam train cost?
A return ticket from Brienz to the Rothorn summit costs roughly CHF 96 for adults at standard fares, with discounts for Swiss Travel Pass and Half Fare Card holders. The steam locomotives run on a limited number of departures per day, so booking or arriving early matters in July and August.
Can I visit Ballenberg and Lake Brienz on the same day?
It’s tight but possible if you start early and pick one lake activity, not two. Ballenberg alone needs 3 to 4 hours to see properly, and it sits on the opposite shore from Giessbach, so factor in the bus or boat transfer time between them.
Why is Iseltwald suddenly popular?
A Netflix series filmed a scene at the small lakeside pier in Iseltwald, and the spot now draws a steady stream of visitors taking the same photograph. The village itself is otherwise a quiet, small settlement with limited parking and few facilities, so expect crowding right at the pier and almost none a street back.
Is there a boat service on Lake Brienz?
Yes, BLS operates scheduled lake boats between Interlaken Ost, Iseltwald, Giessbach and Brienz from spring to autumn, with a reduced winter timetable on some routes. A Swiss Travel Pass covers the boats; a Half Fare Card gives 50 percent off.
