Via Alpina Red R38

The Via Alpina Red R38 is a roughly 13 km point-to-point alpine trail in Austria's Zillertal Alps, running from Finkenberg to the Rastkogelhütte and gaining around 1,300 m of elevation over a single demanding day. Rated difficult, it climbs from a Tyrolean valley village to a high mountain hut with sweeping ridge views across the Tux Alps.

About the Via Alpina Red R38

The Via Alpina Red R38 is stage 38 of the Red Trail, the longest of the five colour-coded routes that make up the Via Alpina, an International Walking Network spanning all eight Alpine countries. The full Red Trail comprises 161 documented stages running from Trieste on the Adriatic to Monaco on the Mediterranean, crossing Slovenia, Austria, Germany, Liechtenstein, Switzerland, Italy, France and the principality of Monaco. The network was created in 2000 by a coalition of public and private organisations from across the Alps and received European Union funding through 2008.

This particular stage links the village of Finkenberg (around 840 m), just south of Mayrhofen in the Zillertal valley, with the Rastkogelhütte (around 2,117 m), a working alpine hut perched on the southern flanks of the Tux Alps. According to the route's OpenStreetMap description, the segment is simply marked "Finkenberg – Rastkogelhütte," and the official operator is via-alpina.org. It is a relentlessly uphill day: hikers leave the green valley floor, climb through spruce forest and onto open alpine pasture, and finish at a hut with commanding views toward the glaciated Zillertal main ridge.

Because the R38 is one link in a continental chain, most people who walk it are thru-hiking a multi-day section of the Red Trail through Tyrol rather than doing it as a standalone outing. That said, the climb to the Rastkogelhütte is a rewarding objective in its own right and is regularly tackled by day hikers and weekend trekkers using Finkenberg or Mayrhofen as a base.

Route Overview & Stages

The R38 is a single stage, but it breaks naturally into three sections by terrain. The figures below are approximate, as the official network does not publish an exact surveyed distance for this segment; treat them as planning estimates for a strong day on the trail.

Total ascent works out to roughly 1,300 m over about 13 km, which most fit hikers cover in five to six hours of walking. The grade is consistently steep, especially in the lower forest, so steady pacing matters more than speed.

Highlights & Points of Interest

• Finkenberg village (840 m) — A compact Tyrolean settlement at the mouth of the Tux valley, with a parish church, traditional guesthouses and the trailhead for the climb.
• Tuxbach gorge — The fast-flowing Tux stream carves through the lower valley; the lower trail offers glimpses of its rushing water through the trees.
• Spruce and larch forest belt — The lower 500 m of climbing winds through dense montane woodland that gives welcome shade on hot summer mornings.
• Open alpine pastures (Almen) — Above the treeline the route crosses working high pastures where Tyrolean cattle graze through summer, dotted with hay huts and wildflowers.
• Rastkogel ridge (2,762 m) — The hut sits beneath this prominent Tux Alps summit, a popular extension for hikers with energy to spare.
• Rastkogelhütte (2,117 m) — A privately run alpine hut offering meals, drinks and overnight bunks, and the official endpoint of the stage.
• Zillertal main ridge panorama — From the hut terrace the glaciated peaks of the Zillertal Alps, including the Hintertux area, fill the southern skyline.
• Connection to the Zillertal Höhenweg — The Rastkogelhütte links into Tyrol's network of high-altitude trails, allowing multi-day extensions in either direction.

Best Time to Hike the Via Alpina Red R38

The R38 is a high-alpine stage, so the practical season is short. The trail and the Rastkogelhütte are realistically accessible from mid-June through late September, with conditions varying sharply across those months. In June, lingering snow patches can persist on the upper pasture above 2,000 m, and the hut may only just be opening for the season.

July and August bring the most reliable footing and the warmest valley starts, but also afternoon thunderstorms that build quickly over the Tux Alps; an early departure from Finkenberg is strongly advised so you reach the hut before midday heat and storm risk. For 2026, plan to be off the exposed upper sections by early afternoon, and always check the hut's opening status before committing, as alpine snow cover and staffing dates shift year to year.

The single best month is September: as of 2026, early autumn delivers stable high-pressure weather, clear long-distance views to the Zillertal glaciers, fewer afternoon storms, thinner crowds on the pastures, and crisp comfortable temperatures for sustained climbing. The main caveat is that the first heavy snowfall can arrive late in the month, so watch the forecast and confirm the hut has not closed for the winter.

Practical Information

Accommodation

The stage endpoint, the Rastkogelhütte (2,117 m), is a privately operated mountain hut providing dormitory bunks and simpler private rooms, plus a kitchen serving hearty Tyrolean fare. Expect roughly €25–€40 per person for a dormitory bed, with private rooms higher; half board (dinner plus breakfast) typically adds €25–€35. Reservation by phone or email ahead of arrival is essential in peak summer, as beds fill on weekends.

In the valley, Finkenberg and neighbouring Mayrhofen offer a full range of guesthouses (Gasthöfe), pensions and hotels, generally €60–€120 per night for a double room with breakfast. Wild camping is restricted across Austrian alpine terrain; if you carry a tent, plan to use a designated valley campsite in the Zillertal rather than pitching on the open pasture. Fuelling well matters on a 1,300 m climbing day — see our guide on how many calories you need hiking a full day to plan your trail food.

Getting There & Back

The natural gateway is Mayrhofen, the terminus of the Zillertalbahn narrow-gauge railway. From Innsbruck main station, take a regional train to Jenbach (about 25–35 minutes), then the Zillertalbahn south to Mayrhofen (about 55 minutes); from there a short local bus or taxi reaches Finkenberg in around 10 minutes. The nearest major airport is Innsbruck (INN), roughly 1.5 hours away by combined train and bus; Munich (MUC) is a larger alternative about 2.5–3 hours north. Public transport in the Zillertal runs frequently in summer, making a car unnecessary for reaching the trailhead.

Permits & Fees

No permit is required to walk the Via Alpina Red R38 — Austria's mountains are freely accessible on foot. There are no trail-access or entry fees for this stage. Your only costs are accommodation, meals at the hut, and transport. If you plan to stay in multiple Alpine Club huts along the broader Red Trail, an Alpenverein (Austrian Alpine Club) membership can reduce nightly hut fees and provides mountain rescue insurance, though the Rastkogelhütte itself is privately run. Confirm current hut rates and opening dates with the operator before you travel.

Gear & Packing List

A 1,300 m climb to a high hut demands proper alpine kit even in midsummer. Carry sturdy, broken-in hiking boots with grippy soles for the steep forest and pasture, trekking poles to save your knees on the descent if you return the same way, and full rain and wind layers — mountain weather in the Tux Alps turns fast. Pack at least 1.5–2 litres of water for the largely shaded-then-exposed ascent, sun protection for the open upper slopes, a warm midlayer for the hut terrace at 2,117 m, and a headtorch.

For a one-night hut stage you want a comfortable daypack in the 35–45 litre range. The Fjällräven Abisko Hike 35 handles a hut overnight with room for layers and a hut sleeping liner. If you are carrying camping gear for a longer Red Trail section, a larger framed pack such as the Osprey Atmos AG 50 or the Deuter Aircontact Lite 45+10 carries multi-day loads in comfort. Ultralight hikers chasing minimum weight on a longer thru can look at a Zpacks Arc Haul Ultra 50L. For a full breakdown of pack choices, see our roundup of the best ultralight backpacks of 2026.

Similar Trails You Might Like

If the steep alpine character of the R38 appeals, Tyrol offers a deep menu of comparable high routes. The classic Berliner Höhenweg Zustieg Ahornbahn starts from the same Mayrhofen area and links the great huts of the Zillertal main ridge, while the multi-stage Stubaier Höhenweg delivers a similar hut-to-hut experience one valley west. For a longer journey across the province, the Adlerweg traces an eagle-shaped line through Tyrol's most dramatic ranges. Long-distance walkers can also look at the lengthy JK01 and JK02 routes, each around 720 km. Further afield, the dramatic Balkan crossing in our guide to the Theth to Valbona trail in Albania offers the same big-climb, mountain-hut reward in a wilder setting.

Frequently Asked Questions

When is the best time to hike the Via Alpina Red R38?

September is the single best month. As of 2026, early autumn brings stable high-pressure weather, clear views to the Zillertal glaciers, fewer afternoon thunderstorms and thinner crowds. July and August are warmer but storm-prone, while June often holds snow above 2,000 m. Always confirm the Rastkogelhütte is open before the first autumn snowfall closes it.

How difficult is the Via Alpina Red R38?

It is rated difficult. The challenge comes from a sustained climb of roughly 1,300 m over about 13 km, much of it on steep forest switchbacks and open alpine pasture. There is no technical scrambling, but the relentless ascent to 2,117 m demands solid fitness, sturdy boots and an early start to beat afternoon mountain storms.

How long does the R38 take to walk?

As a single stage, most fit hikers complete the Finkenberg-to-Rastkogelhütte climb in five to six hours of walking, plus breaks. It is designed as one full day. Because it gains around 1,300 m with little descent, the day is shorter in distance than many stages but physically taxing, so budget extra time if you are carrying a heavy multi-day pack.

Where can I stay along the route?

The stage ends at the privately run Rastkogelhütte (2,117 m), with dormitory bunks from roughly €25–€40 and half board available; reserve ahead in summer. In the valley, Finkenberg and Mayrhofen offer guesthouses and hotels from about €60–€120 per night. Wild camping is restricted, so use a designated Zillertal campsite if you carry a tent.

Do I need a permit to hike the Via Alpina Red R38?

No. Austria's mountains are freely accessible on foot, and there are no permit or trail-access fees for this stage. Your costs are limited to accommodation, hut meals and transport. If you plan to use Alpine Club huts elsewhere on the Red Trail, an Austrian Alpenverein membership lowers hut fees and adds mountain-rescue insurance.
