How big is Lake Schluchsee?

Schluchsee is roughly 5.1 km² in surface area, the largest lake in the Black Forest. It sits at around 930 metres above sea level and has a circular trail of about 18 kilometres. That makes it significantly bigger than the better-known Titisee — and usually less crowded.

Can you swim in Schluchsee?

Yes, swimming is common in summer. The only public bathing area is the Strandbad Aha in the Aha village, with a meadow for sunbathing, a pier, and a kiosk. Water temperature reaches 19 to 21 degrees Celsius in high summer — typical for a reservoir at nearly 1,000 metres altitude.

How do you get from the Feldberg to Schluchsee?

By car it is about 12 kilometres and 15 minutes via the B500. Without a car, you travel free with the Hochschwarzwald Card by bus or by the Dreiseenbahn from Feldberg-Bärental via Altglashütten to Schluchsee — both options take around 20 to 30 minutes.

What is the difference between Schluchsee and Titisee?

Schluchsee is roughly three times larger than Titisee, sits higher (930 m vs 850 m), and is much less touristically developed. Titisee has the famous promenade with souvenir shops and more day visitors; Schluchsee is quieter and more sports-oriented (swimming, SUP, diving, cycling).

Is there a lake cruise at Schluchsee?

Yes, the Schluchsee lake cruise links several piers around the lake in summer — typically Schluchsee, Aha, Seebrugg, and Unterkrummenhof. Current schedules and prices are on hochschwarzwald.de and at the piers. Hochschwarzwald Card holders often pay nothing or a reduced fare.

Is admission to Strandbad Aha free?

No, Strandbad Aha charges an admission fee — the exact seasonal rate changes annually and is shown at the ticket booth on site and on the municipal website schluchsee.de. Overnight guests with the Hochschwarzwald Card usually receive a discounted or free entry.

Schluchsee — Village Guide to the Largest Lake in the Black Forest

The largest lake in the Black Forest — and the village named after it

When our guests ask which half-day trip from the Feldberg is really worth it, the answer is almost always: Schluchsee. With roughly 5.1 km² of surface area it is the largest lake in the Black Forest, it sits at just under 930 metres above sea level, and it is reachable from our apartments at Brünneleweg 4 in about 15 minutes. The village of the same name — actually the municipality of Schluchsee, with the village parts Schluchsee, Aha, Seebrugg, and Faulenfürst — is the starting point for the lake cruise, the 18-kilometre circular trail, and the only public bathing area in the Upper Black Forest.

This guide answers the questions we receive by email before every season: What is there to see in the village? Where do you eat? How do you get there without a car? And above all: Schluchsee or Titisee — which is more worthwhile?

Where Schluchsee is — and why from the Feldberg

Lake Schluchsee lies in the Upper Black Forest, about 12 kilometres south-east of the Feldberg, geographically almost directly at the transition to the Klettgau region and the Wutach Valley. From Feldberg-Bärental station, the Dreiseenbahn takes you just a few stops via Altglashütten and Aha to Schluchsee — one of the most scenic short rides on the German regional rail network, because parts of the route run directly along the water.

For our guests Schluchsee is therefore the obvious half-day or full-day trip: hike at the Feldberg or visit the observation tower in the morning, change direction toward Schluchsee at midday, spend the afternoon at the lake. In summer this works with swimming gear, too — Schluchsee is warm enough to swim in high summer, and the altitude difference of 900+ metres keeps the air pleasant even on hot days.

The village of Schluchsee — four parts, one municipality

What surprises many guests: “Schluchsee” is not a single town, but a municipality with four village parts, each with its own character.

Schluchsee (main village) — the station, the spa park, the lakefront promenade, most restaurants and hotels. When people say “Schluchsee,” they usually mean here.
Aha — a small popular village part on the western shore, home to Strandbad Aha, the only public bathing area at the lake.
Seebrugg — at the southern end of the lake, where the Schluchsee dam stands. Terminus of the Dreiseenbahn and starting point for many hikes.
Faulenfürst — slightly higher up, quieter, without direct lake access. Less relevant for most purposes.

If you arrive by train, you get off in the Schluchsee or Aha village parts — both stations are right by the water.

The main sights in the village

The dam and the reservoir

Schluchsee is a reservoir. What looks like a natural mountain lake has been regulated since the 1930s by the dam at the southern end. The dam itself is walkable and offers one of the best panoramic views over the lake. In spring, when the water level is lowered for the snowmelt, you can sometimes see old structures from the flooded valley — a peculiar, almost eerie sight.

Strandbad Aha — the only bathing area

If you want to swim, you go to Aha. Strandbad Aha is the only public bathing area at Schluchsee, with a meadow, a pier, a kiosk, and in high summer a rental for pedal boats and rowing boats. Admission is charged — the exact daily fee is published on the municipal Schluchsee website. The bath is consistently well-reviewed for its setting (right at the water with a view across the lake); what you should not expect is hotel-pool comfort — it is a lake, not a pool.

St. Nikolaus Catholic church

In the main village stands St. Nikolaus church — not a major sight, but a pleasant rest point with a café nearby. Those interested in architecture will find the typical Upper Black Forest religious building from the late 19th century.

The Schluchsee lake cruise

In summer a passenger boat shuttles between several piers around the lake — typically Schluchsee, Aha, Seebrugg, and Unterkrummenhof. The cruise is the most relaxed way to grasp the geography of the lake. A complete round trip takes around 90 minutes depending on the season. Current schedules are on hochschwarzwald.de and at the piers themselves.

Activities at the lake

The lake loop — 18 kilometres by bike or on foot

Perhaps the best-known trail in the village context is the 18 km lake loop that circles the entire Schluchsee. Paved enough for family bike outings, with moderate gradients, several swimming opportunities along the way, and constant lake views. For hikers a long day (about 5 hours); for cyclists a relaxed half-day.

Water sports — SUP, sailing, diving

Unlike Titisee, Schluchsee is large enough for serious water sports. SUP rental stations can be found in the main village and in Aha; sailing happens mostly from the Schluchsee Yacht Club. A peculiarity: Schluchsee is also a diving spot — because of its depth (over 60 metres at the dam), its visibility, and the submerged structures from the pre-reservoir era.

Swimming — season and temperature

Swimming season typically runs from mid-June to early September. Water temperature reaches 19 to 21 degrees in high summer — cooler than a swimming pool, but quite bearable, especially for swimmers from the Netherlands or northern Germany who are used to cool lake water. Strandbad Aha has a shallow entry zone, so it is suitable for children, too.

Restaurants and cafés

Here we are deliberately reserved: what is worth recommending in the Schluchsee gastronomy scene changes every year. Established and consistently well-reviewed addresses are on hochschwarzwald.de and on Google Maps; personal favourites of our guests — usually the café directly on the lakefront promenade or one of the restaurants in Aha — we can recommend on site. What we can say from experience: on Sundays in high season you need a reservation, especially around midday.

Getting to Schluchsee — car, bus, train

From the Feldberg there are three sensible options:

By car — about 12 kilometres via the B500, 15 to 20 minutes depending on traffic. Parking in Schluchsee, Aha, and Seebrugg is paid; daily rates are moderate, and on summer weekends the lots at Strandbad Aha are full by lunchtime.
By train (Dreiseenbahn) — from Feldberg-Bärental station via Altglashütten to Schluchsee and on to Seebrugg. Travel time about 20 minutes. Hochschwarzwald Card holders travel free.
By bus — line 7300 connects Feldberg and Schluchsee several times a day; here too the Hochschwarzwald Card is valid as the ticket.

Our recommendation: on a sunny summer day take the train, because the route runs partly directly along the lake — one of the most scenic short rides on the German regional rail network.

Schluchsee vs Titisee — a short comparison

The most common question from our guests: “Should we go to Schluchsee or to Titisee?” The honest answer:

Titisee — better known, closer (10 minutes from the Feldberg), more compact, much more touristic (souvenir shops, cuckoo clock stores, more day visitors). Very good for 2 to 3 hours of walking plus an ice cream.
Schluchsee — bigger, quieter, more sporty (swimming, SUP, cycling, diving). Better for half a day or a full day.

If you are staying a week, both are worthwhile. If you only have a day and want to swim or cycle — Schluchsee. If you only have a day and want to see “the Black Forest in concentrate” — Titisee.

A day-plan suggestion: Feldberg and Schluchsee combined

If you stay with us and have a day that combines both:

Morning (9 am to 12 pm) — hike at the Feldberg, for example the Feldberg-Steig or the loop to the Feldsee. Park at Haus der Natur or arrive by bus.
Lunch (12 to 1 pm) — picnic or stop at Feldberger Hof or at Haus der Natur.
Afternoon (1 pm to 6 pm) — train to Schluchsee, walk along the lakefront promenade, swim at Strandbad Aha (in summer), lake cruise, or ice cream at the water.
Evening — back by train to Feldberg-Bärental, dinner in the village or with us on site.

That way a day in the Upper Black Forest feels complete, without you having to rush.
