Via Alpina Purple A66

The Via Alpina Purple A66 is a 17.9-km point-to-point stage in the Allgäuer Alps of Germany, gaining 681 m of elevation while descending 1,698 m from the Prinz-Luitpold-Haus mountain hut (1,846 m) to the resort town of Oberstdorf (815 m) over approximately five and a quarter hours. Rated Alpine Grade II (moderate), it is the triumphant final chapter of the 2,600-km Via Alpina Purple Trail — the longest continuous long-distance hiking route through the Alps, spanning five countries from Slovenia to Germany.

About the Via Alpina Purple A66

The Via Alpina Purple Trail runs across five countries — Slovenia, Austria (Tyrol, Salzburg, and Vorarlberg), and Germany — connecting the Adriatic coast near Trieste with the Allgäu market town of Oberstdorf across 66 numbered stages. Stage A66 is the dramatic conclusion: a high-alpine traverse along one of Germany's most celebrated ridgelines followed by a long, muscular descent into the valley. Completing it means finishing one of Europe's great walk-through-the-mountains journeys.

The stage begins at the Prinz-Luitpold-Haus, a fully staffed DAV (Deutscher Alpenverein — German Alpine Club) mountain hut at 1,846 m in the heart of the Allgäuer Hauptkamm, the main ridge of the Allgäu Alps. From here the route joins the Heilbronner Weg, a high-level ridge path that consistently ranks among Germany's finest alpine walks. The terrain is genuinely alpine: narrow ridges, short scrambles protected by fixed steel cables, and panoramic views that stretch to the Zugspitze and deep into Austria on clear days. This is not a forest trail with a view at the summit — it is exposed, exhilarating ridge terrain for the better part of three hours.

After crossing the Laufbacher Eck (2,178 m), a broad grassy col with exceptional northward views toward the Allgäu foothills and — on exceptional days — the distant shimmer of Lake Constance (Bodensee) some 80 km to the west, the route reaches the Edmund-Probst-Haus at 2,224 m on the Nebelhorn massif. This is the highest point of the day and the last hut for hot food or cold drinks before the long haul down. The final kilometres drop 1,400 m through mixed alpine forest and wide summer meadows, delivering hikers into the pedestrianised heart of Oberstdorf.

Oberstdorf holds a particular status in European long-distance hiking: it is the simultaneous end point of two Via Alpina routes. Stage B40 of the Yellow Trail also terminates here, making the town one of the most symbolically weighted destinations on the continent's long-distance network. The official Via Alpina stage page for A66 provides downloadable GPX data, waypoint lists, and links to the Tannheim-to-Prinz-Luitpold-Haus stage A65 that immediately precedes it.

For hikers new to Bavarian alpine terrain, A66 sits squarely in the moderate-to-challenging bracket. The Heilbronner Weg demands surefootedness and comfort with brief exposed scrambles, but requires no technical climbing experience — the cables and ladder rungs are well-maintained. The dominant challenge for most hikers is the 1,698 m of cumulative descent to Oberstdorf, which punishes unprepared knees. Trekking poles are highly advisable and a 07:00 departure from Prinz-Luitpold-Haus is the standard approach to beat afternoon convective storms on the open ridge. For nutrition planning across a demanding day like this one, understanding how many calories you burn on a full hiking day helps you calibrate your food supply for the stage.

Route Overview & Stages

Stage A66 covers 17.9 km in a single day with no intermediate overnight accommodation between the Prinz-Luitpold-Haus and Oberstdorf. The table below breaks the route into its four natural segments, each with a distinct character and terrain type.

Highlights & Points of Interest

• Prinz-Luitpold-Haus (1,846 m) — A fully staffed DAV mountain hut with dormitory and private-room accommodation, hot meals, and a sun terrace overlooking the Allgäuer main ridge. Open late May through mid-October and the natural overnight base before tackling A66.
• Heilbronner Weg — One of Germany's most iconic alpine ridge walks, threading the Allgäuer Hauptkamm with exposed sections protected by fixed steel cables and iron ladder rungs. Expect close-up views of jagged limestone towers and precipitous drops into green-floored valleys.
• Schönberg saddle — A natural rest point mid-ridge offering sweeping views south into Austria's Lechtal Alps and north toward the gentler Allgäu hills. Frequently carpeted in alpine roses and gentians during July.
• Laufbacher Eck (2,178 m) — A broad grassy col marking the transition from the rocky main ridge to the rounder Nebelhorn massif. On clear days, the distant shimmer of Lake Constance (Bodensee) is visible 80 km to the west, and the Austrian Alps stretch across the full southern horizon.
• Edmund-Probst-Haus (2,224 m) — The highest point of the stage, located just below the Nebelhorn summit. Hot food, cold drinks, and a terrace with panoramic views make this a natural final rest stop. Hikers with tired legs can descend by the Nebelhornbahn cable car rather than continuing on foot.
• Nebelhorn Summit (2,224 m) — A short detour from the Edmund-Probst-Haus adds Germany's southernmost accessible high peak. On exceptional days, views extend across more than 400 named Alpine summits including the Zugspitze, Großer Widderstein, and — in the far distance — the Bernese Oberland.
• Gaisalpsee — A glacier-carved lake sitting at around 1,508 m on the descent route toward Oberstdorf, ringed by steep grassy walls and surrounded by marmot burrows. Often partially frozen into late June, it is a popular half-day destination for Oberstdorf locals and a welcome visual reward after the long descent.
• Oberstdorf town centre (815 m) — Germany's southernmost main settlement and a car-free resort core with a strong tradition as a long-distance hiking terminus. The simultaneous finish point of Via Alpina Purple (A66) and Yellow (B40) trails, with excellent restaurants, gear shops, and rail connections.

Best Time to Hike the Via Alpina Purple A66

The Allgäuer Hauptkamm ridge retains snow well into June, and north-facing couloirs on the Heilbronner Weg can remain icy until early July even after mild winters. The reliable hiking window for A66 runs from late June through late September. Before or after this window, the exposed ridge sections require crampons and an ice axe — well beyond the Grade II rating of the summer route.

July brings wildflowers at their absolute peak. The Laufbacher Eck meadows are blanketed in alpine roses, gentians, and edelweiss, and the light on the Heilbronner Weg ridge at 06:30 is extraordinary. The trade-off is a higher probability of afternoon thunderstorms. Starting from the Prinz-Luitpold-Haus by 07:00 gets you off the exposed ridge before midday convection builds — treat that start time as non-negotiable in July.

August is the single best month for Via Alpina Purple A66. Weather stability is at its annual peak, huts are fully staffed, daylight hours provide a comfortable margin for the 5¼-hour stage, and the long descent to Oberstdorf stays dry underfoot. As of 2026, early-season snow patterns in the Allgäu Alps have been more variable than historical baselines, making late July to mid-August the most dependable window. Book hut beds at least six to eight weeks in advance for August weekends — both the Prinz-Luitpold-Haus and Edmund-Probst-Haus fill well ahead of peak season.

September offers quieter trails, cooler temperatures (ideal for the 1,400 m knee-intensive descent), and statistically excellent visibility for far-ranging summit views. The first snow can dust the high ridge from mid-September onward. Before departing in September, check the Deutscher Alpenverein snow and conditions bulletin and call the Prinz-Luitpold-Haus keeper directly to confirm the ridge is clear.

Practical Information

Accommodation

The standard approach to A66 is to spend the night before at the Prinz-Luitpold-Haus. DAV members pay approximately €24–€30 per person in a shared dormitory (Matratzenlager) and €34–€44 for a private or semi-private room; non-members pay a €6 surcharge per night. Breakfast and a packed lunch are available on request. Pre-booking by email or phone is mandatory from June through September — walk-ins are not accepted in high season.

The Edmund-Probst-Haus at 2,224 m provides hot meals, coffee, and cold drinks throughout the day but does not offer overnight accommodation. It functions as a cable-car-accessible day restaurant and hikers' refuge, which means you can depend on it for a warm lunch break mid-stage but cannot plan to sleep there.

Oberstdorf has over 200 accommodation options. The DJH Oberstdorf youth hostel (jugendherberge.de) offers dormitory beds from approximately €35 per night including breakfast and is popular with Via Alpina finishers. Mid-range Gasthöfe (guesthouses) run from roughly €55–€90 per person per night with dinner; four-star hotels reach €150–€220. Book at least four to six weeks ahead for July and August arrivals.

Getting There & Back

The Prinz-Luitpold-Haus is most easily reached from Bad Hindelang, itself connected to Sonthofen station (Allgäubahn line) by regional bus. From Sonthofen, a taxi or local hiking bus serves the trailhead village of Hinterstein (~12 km); free car parking is available at Hinterstein. A clearly signposted 2.5-hour approach trail climbs from Hinterstein to the hut. Alternatively, stage A65 of the Via Alpina (Tannheim to Prinz-Luitpold-Haus, 14.2 km, +1,100 m) arrives the previous day from Austria.

Munich Airport (MUC) is the nearest international gateway, roughly 2 hours from Oberstdorf by rail via Munich Hauptbahnhof and the Allgäubahn (direct or one change at Immenstadt). Services run approximately every two hours; Oberstdorf station is 500 m from the town-centre finish point of A66. For the return journey, Oberstdorf is well connected to Munich, Stuttgart, and beyond — no special planning is required.

The Nebelhornbahn cable car at the Edmund-Probst-Haus offers an alternative descent if weather closes in or legs give out: a single ride down to the valley station in Oberstdorf costs approximately €20–€25 in 2026 and takes around eight minutes. The cable car operates daily from mid-June to late October.

Permits & Fees

No hiking permit is required for the Via Alpina Purple A66 or any part of the German Alpine trail network. The route passes through the Naturpark Nagelfluhkette and adjacent protected areas, which are freely open to walkers year-round. There are no national park entry fees and no trail-specific charges. The only costs to plan for are DAV hut fees (€24–€44 per night depending on membership status and room type) and the optional Nebelhornbahn cable car (€20–€25 one way). DAV membership costs approximately €72 per year and pays for itself after two or three hut nights across the Alps — it is worth considering for any multi-week Alpine itinerary.

Gear & Packing List

The Heilbronner Weg section involves short hands-on scrambles where a compact, well-balanced pack is preferable to a large expedition rucksack. For a single-stage day hike departing from the Prinz-Luitpold-Haus, aim for 15–25 litres. If you are completing multiple Via Alpina stages back-to-back with hut gear (sleeping bag liner, spare layers, wash kit), 45–60 litres carries everything comfortably.

Three packs suited to different A66 hikers:

• Deuter Aircontact Lite 45+10 — A proven alpine workhorse with an excellent ventilated back panel and load-transfer hip belt. The 10-litre extension accommodates a wet hardshell without unpacking everything. Strong choice for multi-day Via Alpina approaches.
• Osprey Aether 65 — If you are carrying full hut gear across the preceding stages into A66 with loads approaching 15–18 kg, this is a feature-rich and well-padded option that manages weight effectively on long descents.
• Hyperlite Mountain Gear 2400 Windrider — For ultralight hikers tackling A66 as a single fast day from the hut, this sub-750 g pack keeps base weight minimal and stays out of the way on the cable sections of the Heilbronner Weg.

Beyond the pack, the non-negotiables for A66 are: sturdy trail shoes or lightweight boots with a stiff midsole (Heilbronner Weg rocks are hard on flexible soles), a waterproof hardshell jacket (afternoon storms arrive fast on the open ridge), SPF 50+ sunscreen (ridge altitude and reflective limestone intensify UV), and trekking poles (invaluable on the 1,400 m descent to Oberstdorf). Carry at least 2 litres of water from the Prinz-Luitpold-Haus — there are no reliable refill points on the main ridge between the start hut and the Edmund-Probst-Haus. Bring a headlamp in case the descent takes longer than planned.

For a full breakdown of which packs perform best on technical alpine terrain with significant elevation loss, the best ultralight backpacks of 2026 covers seven packs tested on real mountain routes, with particular attention to load control on steep descents.

Similar Trails You Might Like

Via Alpina Purple A66 belongs to the International Walking Network (IWN), a family of cross-border European long-distance routes sharing a philosophy of sustained, committed alpine travel. If the Allgäu Alps appeal and you want to extend your time in the region, or if you prefer lower-altitude trails with a different landscape character, Germany's Europäische Fernwanderwege (European long-distance paths) offer substantial variety. For a wilder contrast — fewer huts, rougher terrain, raw mountain character — the Theth to Valbona hike in Albania is a compelling alternative to Germany's well-serviced Alpine trails.

• Europäischer Fernwanderweg E8, Rheinland-Pfalz — Part of the 4,390-km pan-European E8 route; the Rhineland-Palatinate section traverses the Palatinate Forest, vineyards, and the Rhine gorge.
• Europäischer Fernwanderweg E8, Nordrhein-Westfalen — The North Rhine-Westphalia segment of the E8, crossing the Teutoburg Forest and Sauerland uplands on well-maintained waymarked paths.
• Europäischer Fernwanderweg E11, Sachsen-Anhalt (W) — The western Saxony-Anhalt stretch of the 2,070-km E11, passing through the Harz foreland with its rolling beech forests and historic mining towns.
• Europäischer Fernwanderweg E11, Sachsen-Anhalt (O) — The eastern Saxony-Anhalt section of the E11, a gentler route crossing the Fläming heath — excellent for spring hiking when the Allgäu ridge is still snow-bound.
• Europäischer Fernwanderweg E11, Brandenburg (O) — Brandenburg's eastern E11 segment, a lake-dotted lowland route through the Spreewald biosphere reserve and the Lausitz — a complete change of pace from high-alpine terrain.

Frequently Asked Questions

When is the best time to hike the Via Alpina Purple A66?
August is the most reliable month — the Heilbronner Weg ridge is consistently snow-free, huts are fully staffed, and afternoon storm risk is lower than in July. The full hiking window runs from late June through late September. July offers peak wildflowers but demands an early start. September is quieter with sharp visibility but requires checking snow conditions before departure from mid-month onward.

How difficult is the Via Alpina Purple A66?
The stage is rated Alpine Grade II (moderate). The Heilbronner Weg involves short exposed scrambles with fixed cables — surefootedness is required but no technical climbing experience. The dominant challenge is the 1,698 m cumulative descent to Oberstdorf, which is hard on unprepared knees. Trekking poles and sturdy footwear with a stiff midsole are strongly recommended. A 07:00 start from the Prinz-Luitpold-Haus keeps you off the open ridge before storm weather builds.

How many kilometres per day should I plan for the approach into A66?
The Via Alpina Purple stages leading into A66 average 15–18 km with 800–1,100 m of gain. Stage A65 immediately before (Tannheim to Prinz-Luitpold-Haus) covers 14.2 km with 1,100 m of gain — a full day's work. Plan one rest night at Prinz-Luitpold-Haus before A66 so you start the ridge fresh, and budget 5–6 hours for A66 itself if carrying an overnight pack.

What accommodation is available on the Via Alpina Purple A66?
The Prinz-Luitpold-Haus at the stage start offers dormitory beds from ~€24 (DAV members) and private rooms to ~€44. The Edmund-Probst-Haus at 2,224 m has hot meals but no overnight beds. Oberstdorf has 200+ options from the DJH youth hostel (~€35/night) to hotels (~€80–€220/night). Pre-book hut accommodation at least six to eight weeks ahead for July and August.

Do I need permits to hike the Via Alpina Purple A66?
No permits or trail access fees are required. The route crosses the Naturpark Nagelfluhkette and adjacent protected areas, all freely open to walkers. The only costs are hut fees (~€24–€44 per night, lower with DAV membership) and the optional Nebelhornbahn cable car (~€20–€25 one way). DAV membership (~€72/year) pays for itself after two or three hut nights across the Alps.
