Via Alpina Red R37

The Via Alpina Red R37 is a roughly 9 km point-to-point trail in the Zillertal Alps of Tyrol, Austria, descending about 160 m from Ginzling to Finkenberg over a single day. Rated easy to moderate, it is a short valley-floor stage on the 161-stage Red Trail that links Trieste to Monaco across the Alps.

About the Via Alpina Red R37

The Via Alpina is a network of five long-distance hiking trails crossing eight Alpine countries: Slovenia, Austria, Germany, Liechtenstein, Switzerland, Italy, France, and Monaco. The flagship Red Trail runs 161 stages from Muggia near Trieste in Italy to the Place du Palais in Monaco, and stage R37 is one of its Austrian links, threading through the heart of Tyrol's Zillertal valley.

R37 connects the mountain hamlet of Ginzling with the larger village of Finkenberg, following the floor of the Zemm valley below the Zillertal Alps. It is one of the gentlest stages on the entire Red Trail — a transit day rather than a summit push — covering roughly 9 km with a net descent of about 160 m, from Ginzling near 995 m down to Finkenberg around 840 m. The official route is catalogued as stage 217 in the Via Alpina database maintained by the trail's operator, via-alpina.org.

The Via Alpina was created in 2000 by organisations from across the Alpine arc and received EU funding from 2001 until 2008. The initiative was led by the Grande Traversée des Alpes in Grenoble, with secretariat operations later transferred to CIPRA in Liechtenstein. Its stated aim is to support sustainable development in remote mountain areas and promote Alpine cultures and cultural exchange — and R37 is a textbook example, linking working alpine villages rather than chasing the highest passes. For walkers planning a multi-day push, this stage pairs naturally with R36 (which arrives at Ginzling) and R38 (which climbs onward from Finkenberg toward Mayrhofen and the high country).

The Zillertal Alps that frame R37 form the most heavily glaciated range in the Eastern Alps outside the Hohe Tauern, with summits such as the Hochfeiler (3,509 m) and Olperer (3,476 m) rising on the Austrian–Italian frontier just a few valleys south. From the floor of the Zemm valley you rarely see those giants directly, but their meltwater feeds every stream you cross, and the entire stage sits within the buffer of the Naturpark Zillertaler Alpen, established in 1991 to protect this landscape. R37 is therefore less about altitude and more about reading the valley: terraced hay meadows, weathered timber barns, and a river that has shaped human settlement here for more than a thousand years. Walkers who treat it as a slow, observant day rather than a sprint to Finkenberg come away with the clearest sense of why the Via Alpina was routed through these communities in the first place.

Route Overview & Stages

R37 is a single official Via Alpina stage, but the walk divides naturally into three sections along the Zemm valley. The table below breaks down the day so you can pace your hike and pick rest stops.

Total distance is roughly 9 km with around 90 m of cumulative ascent and 250 m of descent, giving the net loss of about 160 m. Most walkers complete R37 in 2 to 3 hours at a relaxed pace, making it an ideal recovery day or a half-day warm-up before tackling the steeper Tyrolean stages that follow.

Highlights & Points of Interest

• Ginzling (995 m) — A protected mountain village and the gateway settlement of the Naturpark Zillertaler Alpen, with a visitor centre explaining the geology and wildlife of the surrounding peaks.
• Naturpark Zillertaler Alpen — Austria's largest nature park at over 420 km², shielding glaciers, high pastures and the Zillertal's three-thousanders from development.
• Zemmbach river — The glacier-fed torrent that carved the valley; the trail follows its course for much of the day, with footbridges and cool, spray-misted pools.
• Zemm gorge (Zemmschlucht) — A narrow rock-walled defile where the river squeezes between cliffs, a scenic highlight midway through the stage.
• Persal hamlet — A cluster of traditional Tyrolean farmhouses on the hillside, illustrating the working alpine landscape the Via Alpina was designed to celebrate.
• Finkenberg (840 m) — A historic Bergsteigerdorf (mountaineering village) with the Penken cable car, restaurants and onward bus links to Mayrhofen.
• Penkenbahn base station — At Finkenberg, a gondola lifts hikers to the high Penken plateau for those wanting to extend the day with ridge walking.
• Teufelsbrücke viewpoint — A dramatic span over the gorge near Finkenberg offering one of the best photo stops of the lower Zemm valley.

Best Time to Hike the Via Alpina Red R37

Because R37 stays on the valley floor between roughly 840 m and 995 m, it has a far longer season than the high passes elsewhere on the Red Trail. The path is generally walkable from late April to early November, though snowmelt can leave sections muddy in spring and the Zemmbach runs high and fast through May and June.

The single best month is September. As of 2026, September brings stable high pressure, daytime valley temperatures around 16–20 °C, clear air for photographing the surrounding peaks, and far fewer crowds than the July–August school holidays. Autumn colour begins to touch the larch forests by late in the month, and the Zillertal's huts and gondolas typically operate into early October. July and August are warmest and busiest, with afternoon thunderstorms common; start before noon to stay ahead of them. By November, the first valley snowfalls and reduced bus frequencies make logistics harder, and most high-altitude infrastructure closes.

For Northern Hemisphere planning context, expect roughly 13 hours of daylight in mid-September — ample for a stage you can finish in under three hours. If you are combining R37 with adjacent high stages, the calculus changes: the Berliner Höhenweg and other ridge sections above the valley hold snow into early summer and can see fresh snowfall by late September, so check current hut reports before committing to a high-level itinerary. The valley stage itself, however, remains low-risk well outside the peak season, which is part of what makes R37 a reliable connector when weather closes the passes above.

Whatever month you choose, start your walking day early. Afternoon convective storms build quickly over the Zillertal's glaciers in summer, and even on this sheltered valley route a downpour can turn the gorge path slippery within minutes. A pre-noon start also rewards you with the best light on the surrounding rock walls and the quietest stretch of trail before day-trippers arrive from Mayrhofen.

Practical Information

Accommodation

Both endpoints offer beds, so there is no need to camp on R37. In Ginzling, guesthouses (Gasthof and Pension rooms) typically run €45–75 per person per night with breakfast. Finkenberg, being larger, has hotels, apartments and B&Bs ranging from €55 to €110 per person depending on season and category. For a hut-style experience, the higher Berliner Höhenweg refuges near the valley charge around €18–25 for a dormitory bed (members of an alpine club pay less), plus €5–8 for breakfast. Wild camping is restricted across the Naturpark Zillertaler Alpen, so use designated valley campsites near Mayrhofen, where pitches cost roughly €10–15 per person.

Getting There & Back

The Zillertal is reached via Jenbach, on the main Innsbruck–Munich railway line. From Jenbach, the narrow-gauge Zillertalbahn runs to Mayrhofen (about 55 minutes), from where regional buses (lines toward Ginzling and the Schlegeis reservoir) reach Ginzling in roughly 25–30 minutes and Finkenberg in about 10 minutes. Innsbruck Airport is the nearest international gateway, around 75 km and a 70–90 minute transfer away; Munich Airport is a larger hub roughly 2.5 hours by car or rail-and-bus combination. Because R37 is point-to-point, the easiest plan is to base in Mayrhofen and use the postbus to reach Ginzling at the start and return from Finkenberg at the end.

Permits & Fees

No permit or entry fee is required to walk R37 — the Via Alpina and the Naturpark Zillertaler Alpen are free to access on foot. Budget only for transport (a day ticket on the regional buses is around €10–14), optional gondola rides on the Penkenbahn (roughly €30 return), and accommodation. A guest card (Zillertal Activcard or local Gästekarte) issued by your accommodation often includes free or discounted regional buses and cable cars, which can substantially cut your costs over a multi-day stay.

Gear & Packing List

R37 is a low-altitude valley stage, so you do not need full mountaineering kit — but Alpine weather shifts fast and the Zemmbach spray keeps the trail damp, so pack sensibly. A lightweight 35–50 litre pack is ample for a day stage or a multi-day Via Alpina section. The Abisko Hike 35 suits a day-tripper carrying lunch and layers, while a load-hauling option like the Aircontact Lite 45+10 works for hut-to-hut walkers carrying a sleeping bag liner and spare clothing. Ultralight thru-hikers stringing together many Red Trail stages may prefer the 2400 Windrider for its sub-kilogram weight.

Bring waterproof boots or trail shoes with grip for the occasional muddy gorge section, a rain shell, an insulating mid-layer, sun protection, and 1.5–2 litres of water. The Zillertal's gondolas and guesthouses mean you can resupply easily, but carry snacks — read how many calories you need hiking a full day to dial in your food.
