[E4/E5] Europäischer Fernwanderweg Rhein bis Grenze D

The E4/E5 Europäischer Fernwanderweg from the Rhine to the German border is a point-to-point alpine trail in Vorarlberg, Austria, threading the Bregenzerwald between Lake Constance and the Allgäu Alps. As a stretch of the 12,090-km E4 — Europe's longest waymarked route — it climbs through subalpine pasture and limestone ridges, rated moderate for fit walkers carrying multi-day loads.

About the E4/E5 Europäischer Fernwanderweg Rhein bis Grenze D

The E4/E5 Europäischer Fernwanderweg Rhein bis Grenze D is the Austrian connecting section of the European Long-Distance Path E4, the longest of the continent's eleven E-paths at roughly 12,090 kilometres from Cape St. Vincent in Portugal to Acheleia on Cyprus. This particular segment carries the walker out of the Rhine valley near Lake Constance, across the rolling green of the Bregenzerwald, and up to the limestone frontier ridges that mark the border with Germany's Allgäu.

The route is coordinated by the European Ramblers Association (Europäische Wandervereinigung), the federation of national hiking clubs that has maintained the E-path network since 1969. On the ground, the waymarking is handled by the Austrian alpine clubs and the Vorarlberg regional authorities, so you follow the familiar red-white-red Austrian blazes and the E4 logo rather than a single dedicated sign. The OSM relation describes it simply as "Europäischer Fernwanderweg E4/E5 Bregenzer Wald," reflecting that the E4 and the parallel E5 share trail here before the E5 swings south toward the Ötztal and the E4 continues east along the Northern Limestone Alps.

Because this is a transit corridor rather than a tidy named circuit, the exact distance is not officially fixed — most walkers cover it in three to five days depending on which valley they start from and whether they take the gentle foothill variant or the higher subalpine line. The Bregenzerwald itself is a UNESCO-recognised cultural landscape of dairy farms, wooden shingle architecture and Alpkäse cheese huts, which gives the walking a distinctly lived-in, pastoral character compared with the bare high-alpine drama further south. Expect modest but persistent elevation: individual stages typically gain 700–1,100 m, and the cumulative climb across the section runs well past 4,000 m.

If you are new to multi-day European trails, this segment is a forgiving introduction — villages, buses and dairy huts are never far away — while still delivering genuine ridge walking. For a tougher Alpine contrast you might later look at the Theth to Valbona crossing in the Albanian Alps, a single dramatic pass day that makes a good companion objective.

Route Overview & Stages

The stages below describe a typical west-to-east itinerary from the Rhine valley at Hohenems/Bregenz across the Bregenzerwald to the German border near the Allgäu. Distances are approximate, since the path links several existing regional trails rather than a single surveyed route.

Taken together the five stages add up to roughly 95 kilometres with more than 4,800 m of ascent. Strong hikers compress the route into three long days; most take four or five and build in a rest afternoon for the dairy huts and a cheese-making demonstration in the Bregenzerwald.

Highlights & Points of Interest

• Lake Constance (Bodensee) overlook — the opening climb out of the Rhine valley delivers a sweeping view across the 536 km² lake shared by Austria, Germany and Switzerland, with the Säntis massif on the horizon.
• Pfänder foothills — the 1,064 m Pfänder above Bregenz is the classic gateway summit to the Bregenzerwald, reachable on foot or by cable car for those starting low.
• Bezau and the wooden-architecture villages — Bezau, Andelsbuch and Schwarzenberg are showcases of the Bregenzerwald shingle-clad building tradition celebrated through the regional Werkraum design network.
• Kanisfluh — the 2,044 m limestone wall is the signature peak of the central Bregenzerwald, its long south face dominating the skyline above the Bregenzerach.
• Niedere ridge — a gentle 1,711 m grassy crest between Andelsbuch and Bezau offering an easy panoramic traverse and one of the area's best sunrise viewpoints.
• Hochtannberg pass — at 1,676 m this saddle near Schröcken marks the watershed toward the Lech valley and Warth–Schröcken ski terrain, with high alpine meadows on either side.
• Alpkäse dairy huts (Sennereien) — working summer alps along the route sell raw-milk mountain cheese; the KäseStrasse Bregenzerwald links dozens of these huts and village dairies.
• Limestone frontier ridge to the Allgäu — the final stage climbs onto the karst border crest where the Austrian route hands off to Germany's Maximiliansweg, closing the section at the national boundary.

Best Time to Hike the E4/E5 Europäischer Fernwanderweg Rhein bis Grenze D

The reliable hiking window runs from mid-June to early October. Snow lingers on the higher passes such as the Hochtannberg into early June, and the dairy huts and valley buses keep their summer timetables only once the season is fully underway. September is the single best month to walk this section: the summer thunderstorm pattern has eased, the air is clear enough to see from the frontier ridge across to Lake Constance, the meadows are still green, and the Alpkäse huts are at the height of cheese season before they close down for autumn.

July and August bring the warmest, longest days but also the most crowded huts and the highest chance of afternoon convective storms — start early and aim to be off the exposed ridges by 14:00. As of 2026, Vorarlberg's tourism boards and the alpine clubs continue to publish updated hut-opening and avalanche-residual notes each spring, so confirm the Hochtannberg and Schröcken sections before an early-season attempt. October walking is possible in a settled spell but daylight shortens fast and the first snow can arrive on the limestone crest at any point in the month.

Spring (April–May) is generally too early above 1,500 m: the upper pastures are wet, snowfields block the passes, and many Sennereien have not yet moved their herds up. If you only have a spring window, stick to the lower foothill variant near Lake Constance and save the ridge stages for summer.

Practical Information

Accommodation

This section is unusually comfortable for an alpine long-distance trail because it passes through inhabited valleys every day. Each stage ends in or near a village — Lingenau, Bezau, Schoppernau, Schröcken — where you can choose between guesthouses (Gasthöfe), small hotels and a handful of alpine huts. Typical 2026 prices: a dormitory bed in an alpine club hut runs €25–€38 per night, with half-board (dinner plus breakfast) adding €22–€30; a private room in a valley Gasthof costs €70–€120 for two including breakfast. Members of the Alpenverein (DAV/ÖAV/AVS) receive substantial discounts on hut dormitory rates, often 50 percent, which pays for itself over a multi-day trip.

Designated campsites exist in Bezau and near Au/Schoppernau, charging roughly €10–€16 per person plus a small pitch fee. Wild camping is legally restricted in Vorarlberg, so plan to use official sites or huts rather than pitching on the open alp. Book hut and Gasthof beds ahead for July, August and any weekend in September.

Getting There & Back

The natural gateway is Bregenz on Lake Constance, served by frequent ÖBB trains on the Lindau–Bregenz–Feldkirch line; from Zürich Airport the journey takes about 1 hour 40 minutes by direct train, and from Munich roughly 2 hours 30 minutes via Lindau. The closest international airports are Friedrichshafen (about 40 minutes away by train and ferry across the lake), Zürich (around 1 h 40 m) and Munich (around 2 h 30 m).

Within the Bregenzerwald, the Landbus Bregenzerwald network connects every village on the route — Bregenz, Bezau, Au, Schoppernau, Schröcken — at hourly or better frequency in summer, so you can shorten a stage or bail to a bus without trouble. At the eastern end, the Hochtannberg and Warth–Schröcken stops link onward toward the Lech valley. Plan timetables with the regional transport authority; the Verkehrsverbund Vorarlberg (vmobil) journey planner covers all bus and rail services in the region.

Permits & Fees

No permit is required to walk the E4/E5 through Austria — the country guarantees open access to mountain terrain, and the trail is free to use. Your only costs are accommodation, food and transport. Cable cars used to shortcut climbs (Pfänderbahn in Bregenz, Bezau Seilbahn, Diedamskopf gondola) charge €18–€30 for a one-way or return ticket. If you join the Alpenverein for hut discounts, annual membership is roughly €68 for an adult and also includes mountain-rescue and liability insurance valid across the Alps — useful background reading is available from the Österreichischer Alpenverein.

Gear & Packing List

Because you sleep in huts and guesthouses rather than tents, this is a light-pack route: a 35–50 litre bag is plenty for three to five days. A frameless or lightweight pack such as the Hyperlite Mountain Gear 2400 Windrider suits hut-to-hut travel, while those carrying a tent for the valley campsites or extra layers for shoulder-season cold will prefer the larger Hyperlite Mountain Gear 3400 Windrider. For a more structured load-carry with a ventilated back panel — welcome on the warm pasture climbs — the Fjällräven Abisko Hike 35 is a comfortable all-rounder. If you want to compare current options, our roundup of the best ultralight backpacks of 2026 ranks seven tested packs.

Essential kit: B-rated approach or light hiking boots with grip for wet limestone, waterproof shell and warm midlayer (mountain weather turns fast even in July), 1.5–2 litres of water capacity, sun protection for the open ridges, and a hut sheet liner required by Alpenverein dormitories. Trekking poles ease the repeated 1,000 m climbs and descents. Carry enough cash for the smaller dairy huts, which often do not take cards.

Frequently Asked Questions

When is the best time to hike the E4/E5 from the Rhine to the German border?
Mid-June to early October is the reliable window, and September is the standout month. By then summer thunderstorms have eased, visibility from the frontier ridge to Lake Constance is at its clearest, and the Bregenzerwald dairy huts are still selling fresh Alpkäse. Avoid early June, when snow can still block the Hochtannberg pass.

How difficult is this section of the E4/E5?
It is rated moderate. There is no glacier travel or technical scrambling, but each stage climbs 700–1,100 m on mountain paths that can be steep, rocky and slippery when wet. You need solid fitness for consecutive big-ascent days and a head for exposed ridge walking near the German border, yet villages and buses are never far if you need to shorten a stage.

How many kilometres per day should I plan?
Stages here run roughly 16–22 km with 750–1,100 m of climbing, so 18–20 km is a realistic daily target for most hikers. That pace covers the section in four to five days. Strong walkers compress it into three long days, but the frequent dairy huts and shingle-clad villages reward a slower rhythm with a rest afternoon built in.

What accommodation is available along the route?
You can sleep indoors every night. Each stage ends near a village with guesthouses (€70–€120 per double room) and small hotels, plus alpine club huts offering dormitory beds at €25–€38 in 2026, often half-price for Alpenverein members. Official campsites operate in Bezau and near Schoppernau; wild camping is restricted in Vorarlberg, so use sites or huts.

Do I need a permit or pay any fees?
No permit is required — Austria grants open access to mountain terrain and the trail itself is free. Your costs are accommodation, food and transport. Optional cable cars cost €18–€30, and Alpenverein membership (about €68 per year) earns hut discounts plus mountain-rescue insurance, which usually pays for itself over a multi-day hut trip.
