Overview
Lake Constance — known in German as the Bodensee — sits at the meeting point of Switzerland, Germany, and Austria. The Swiss canton of Thurgau occupies most of the southern shore, with the canton of St. Gallen holding the southeastern corner. The Swiss side is quieter and less heavily touristed than the German shore, offering apple orchards, cycling paths, and modest lakeside villages rather than large resort infrastructure.
The lake itself is one of the largest in central Europe, roughly 63 kilometres long and up to 14 kilometres wide. Fed by the Rhine, it drains westward at Konstanz before the Rhine resumes its course toward Basel. The landscape is flat to gently rolling along the Swiss shore, backed by the Appenzell hills and, on clear days, a panorama of the Alps to the south.
The main Swiss towns on the lake — Kreuzlingen, Steckborn, and Arbon — each have a distinct character: Kreuzlingen borders the German city of Konstanz almost seamlessly; Steckborn is a small, well-preserved medieval market town; Arbon sits on a small peninsula with a visible Roman and medieval heritage. Romanshorn serves as the main ferry hub on the Swiss side.
Because the region straddles three countries, visitors often combine the Swiss shore with day trips to Konstanz, Meersburg, or the island of Mainau in Germany, or cross to Bregenz in Austria. A multi-country lake circuit is one of the most practical ways to experience the area.
Before You Go
Visas and Entry
Switzerland is not an EU member but participates in the Schengen Area, which also covers Germany and Austria. Because the Lake Constance region sits at a three-country border, entry rules apply at each crossing. For current visa requirements specific to your nationality, check TravelerPulse's Visas section and the Swiss State Secretariat for Migration (SEM) website.
Health and Insurance
Travel insurance that covers medical evacuation is recommended for Switzerland given the cost of healthcare. EHIC or GHIC cards (for eligible EU/UK travellers) are not valid in Switzerland. Verify coverage with your insurer before travel.
What to Pack
The lake microclimate is milder than inland Switzerland, but evenings can be cool even in summer. A light waterproof layer is practical year-round. If you plan to cycle — the most popular way to explore the shore — verify whether your accommodation can arrange or recommend rental.
Getting There
By Air
The closest international airports are Zurich (ZRH), approximately 70–80 kilometres to the southwest, and Friedrichshafen (FDH) on the German shore, which is small but convenient. Stuttgart and Munich airports are also within reasonable driving or rail distance. Verify current rail connections and journey times on the SBB (Swiss Federal Railways) website or the relevant national rail operator.
By Rail
Swiss Federal Railways (SBB) connects Zurich to Kreuzlingen and Romanshorn directly. The lakeside rail line along the Swiss shore passes through Kreuzlingen, Gottlieben (request stop), Steckborn, Mammern, and onward. The Eurocity network links Zurich to Bregenz and beyond, running along or near the southern shore. Interrail and Eurail passes are valid on SBB; the Swiss Travel Pass covers most Swiss lake ferries as well — verify current pass inclusions before purchase.
By Car
The Swiss A7 motorway connects Zurich to Kreuzlingen. A Swiss motorway vignette (annual sticker) is required on Swiss national roads; purchase one before or at the border. Parking in small lakeside towns can be limited in summer.
By Ferry
During the navigation season (broadly April to October, with reduced winter service), passenger ferries operated by Schweizerische Bodensee Schifffahrtsgesellschaft (SBS) and the Bodensee-Vorarlberg shipping company connect Swiss, German, and Austrian ports. Romanshorn–Konstanz is a major car-ferry crossing. Verify current timetables and whether your rail pass grants free or reduced passage directly with the operators.
Getting Around
Cycling
A dedicated lakeside cycling path (part of the international Bodensee-Radweg) follows the entire Swiss shore and continues around the lake through Germany and Austria — roughly 260 kilometres for the full circuit. The Swiss section is largely flat and well-signed. Bike rental is available in larger towns; verify locally for current providers and pricing.
Ferry
Ferries are the most enjoyable and practical way to move between Swiss and German or Austrian ports, and connect key stops that rail does not serve directly. The car ferry between Romanshorn and Konstanz is frequent and takes around 40 minutes. Passenger-only boats serve smaller stops.
Train
The regional rail line hugging the Swiss shore is reliable and frequent, though it bypasses a few small villages. It is the fastest option for longer shore-to-shore hops.
Car
A car gives flexibility for reaching inland villages and the Untersee (the western arm of the lake), but the lakeside road through small towns can be slow in summer. Street parking fills quickly near the water on warm weekends.
Things to See & Do
Kreuzlingen and the Augustinian Monastery
Kreuzlingen's Augustinian monastery church, with its intricate Baroque interior, is considered one of the notable religious art ensembles in the canton of Thurgau. The town itself blends into German Konstanz — crossing the border is a short walk through what is now an open Schengen passage, giving easy access to Konstanz's medieval old town, cathedral, and Konzil building.
Arbon
Arbon occupies a small promontory that has been settled since at least Celtic times. The lakeside castle (Schloss Arbon), which houses a regional history museum, and the remains of Roman fortifications make it one of the more historically layered stops on the Swiss shore. The lake promenade here is pleasant for an evening walk. Verify museum opening hours locally or on the town's official site.
Steckborn
This small market town has a well-preserved old town and a compact lakeside Turm (tower remnant of its medieval fortifications). The Turmmuseum covers local history. The town is less visited than Kreuzlingen or Arbon and has a quiet, unhurried atmosphere.
Lake Swimming
Public swimming areas (Badis) are a Swiss institution, and several lakeside communes maintain clean, free or low-cost bathing spots with changing facilities. Water quality in Lake Constance is generally considered good — it supplies drinking water to millions of people — but verify current conditions locally.
Wine and Apple Country
Thurgau is Switzerland's largest apple-growing canton and a significant producer of cider (Most) and fruit schnapps. It also produces wine, primarily from Müller-Thurgau (a grape variety actually named after a Thurgau researcher). Roadside farm stalls selling juice, cider, and wine are common in autumn.
Day Trip: Mainau Island (Germany)
Mainau, a few kilometres off the German shore accessible by ferry, is a garden island owned by the Bernadotte family with botanical gardens, a Baroque church, and walking paths. It is privately run; verify current admission fees and ferry access on the Mainau official site.
Day Trip: Konstanz Old Town (Germany)
Konstanz is the largest city on the lake and has a well-preserved medieval centre, the Gothic Münster cathedral, and a lively waterfront. It is an easy walk or short ferry ride from Kreuzlingen.
Food & Drink
Regional Specialities
Lake Constance yields freshwater fish that appear regularly on local menus — Felchen (whitefish/coregonid) is the most prized, typically pan-fried or smoked. Egli (perch fillets) is another common preparation. Look for seasonal fish menus at lakeside restaurants, though be aware that overfishing pressure in recent decades has led some restaurants to source fish partly from aquaculture; ask your server for provenance if this matters to you.
Thurgau's apple-growing tradition means that apple juice, sparkling cider, and fruit-based spirits appear as local drinks alongside Swiss wines. A glass of local Müller-Thurgau white wine pairs well with fish.
Dining Patterns
Swiss meal times are conventional Central European: lunch is typically noon–2 pm, dinner from 6 or 6:30 pm. Many smaller restaurants in village settings take a day off mid-week (often Monday or Tuesday) — verify before making a special trip. Prices reflect Swiss cost-of-living levels, which are generally higher than in neighbouring Germany or Austria.
Practical Notes
Service charges are usually included in Swiss restaurant bills, though rounding up the total is customary. Credit cards are widely accepted, but some farm stalls and small cafés prefer cash.
Practical Information
Money
The Swiss Franc (CHF) is the currency throughout the Swiss side of the lake. German euros and Austrian euros are not accepted in Switzerland, though some border businesses near Kreuzlingen may accept euros informally — do not rely on this. ATMs are available in all main towns.
Connectivity
Mobile coverage is generally good throughout the Swiss shore. EU roaming rules do not apply in Switzerland, so travellers with EU SIMs should check their operator's Switzerland roaming charges before arrival.
Emergency Services
In Switzerland, dial 117 for police, 144 for ambulance, and 118 for fire. The European emergency number 112 also works. If crossing into Germany or Austria, country-specific emergency numbers apply (Germany: 110 police / 112 emergency; Austria: 133 police / 144 ambulance — verify these locally).
Accessibility
The flat terrain of the Swiss lakeside makes it more accessible than much of Switzerland for travellers with mobility considerations. Paved promenades exist in Arbon, Romanshorn, and Kreuzlingen. Verify specific facility details with individual sites before travel.
Public Holidays
Cantonal public holidays in Thurgau and St. Gallen may differ from the national calendar; some sites and services close on these days. Check dates for your travel period in advance.
Safety
Lake Constance is a low-risk destination by most measures. General urban safety precautions apply in all towns.
On the water: the lake can produce sudden squalls, particularly in summer afternoons. If renting a boat or paddleboard, check weather forecasts and heed any warning flags displayed at official bathing areas. Swimming outside designated zones can be hazardous due to ferry traffic on the main shipping lanes.
Border crossing: the Kreuzlingen–Konstanz crossing is open under Schengen but spot checks do occur. Carry your passport or national ID. Rules for what goods can be carried between Switzerland and EU countries differ from intra-EU crossings — customs allowances apply.
