Via Alpina Purple A13

The Via Alpina Purple A13 is an 18-km point-to-point trail in Austria, part of the International Walking Network's 2,600-km Via Alpina Purple Route crossing eight Alpine nations. The stage gains approximately 900 m of elevation as it traverses classic Austrian mountain terrain — steep forested flanks, open high pastures and traditional farming hamlets — making it a moderately challenging day on one of the world's most celebrated long-distance hiking routes.

About the Via Alpina Purple A13

The Via Alpina Purple Trail is one of five colour-coded routes that cross the Alps from end to end. The Purple Route — the longest of the five at roughly 2,600 km across eight countries — stretches from Trieste in Italy to Monaco on the French Riviera, threading through Slovenia, Austria, Germany, Liechtenstein, Switzerland, France and Monaco. Stage A13 sits within the Austrian section, where the trail navigates the limestone ranges and river valleys that define the Northern Limestone Alps.

Austria accounts for a large share of the Purple Trail's mileage, and Stage A13 exemplifies the character of this stretch: high-level traverses above timberline, steep descents into deeply carved valleys, and the kind of Almdorf (Alpine hamlet) culture that has sustained mountain farmers here for centuries. The waymarking — a purple diamond or blaze on posts and rocks — is consistent and reliable throughout Austria, making navigation straightforward even without GPS.

This stage is operated by the Via Alpina association, a cross-border partnership of national hiking federations. In Austria, the trail is co-managed by the Österreichischer Alpenverein (ÖAV), whose hut network provides most of the overnight infrastructure along the route. For hikers planning the full Purple Trail or the Austrian stages as a standalone multi-day trip, Stage A13 slots naturally into a 5–7 day loop through the region's most scenic terrain.

At 18 km, this is a full but achievable day stage for fit hikers. Expect around 5–7 hours of walking time depending on pace and photo stops — and there are plenty of reasons to stop. The Northern Limestone Alps offer dramatic cliff faces, karst sinkholes and the sudden drama of a ridge opening onto a 360-degree panorama that extends far into the Bavarian Prealps on clear days.

Route Overview & Stages

Stage A13 connects two valley communities via a high ridge crossing. The route climbs steeply from the starting valley, levels out across open Alpine meadows at around 1,700–1,900 m, then descends through forest to the end point. The table below breaks the stage into its three natural walking sections.

The total cumulative elevation gain sits around 900 m, with a similar loss on the descent side. This profile — long climb, ridge traverse, long descent — is typical of the Austrian Purple Trail stages and rewards hikers with maximum time above the treeline relative to total distance covered.

Highlights & Points of Interest

• Northern Limestone Alps ridge views: The high point of the stage, reached after the initial forest climb, opens onto a sweeping panorama across the Kalkalpen. On clear days the view extends north into the Bavarian foothills and south towards the Central Alps; this is the natural lunch stop for most hikers.
• Working Alm (Alpine dairy farm): Mid-stage, the trail passes an operational summer dairy farm where cattle graze open meadows from June to September. Fresh Bergkäse (mountain cheese) and buttermilk are typically available — a genuine farm-to-hiker experience unique to the Austrian Alps.
• Karst sinkholes and limestone pavement: The ridge section crosses a karst plateau where rainwater has dissolved the limestone into pits, channels and sculpted rock faces. This landscape type is a hallmark of the Northern Limestone Alps and is rarely seen this accessibly on a waymarked trail.
• Forest sections with old-growth beech: The descent passes through one of the region's protected beech-fir forest zones. Centuries-old beech trees create a cathedral-like canopy, and red deer are frequently spotted in the early morning hours.
• Traditional Gasthof at stage end: The arrival village typically hosts a family-run Gasthof (inn) where hikers finish the stage with a Radler (beer-lemonade mix) and Wiener Schnitzel — an Austrian trail tradition that should not be skipped.
• Purple Trail waymarking posts: The distinctive purple diamond blazes on wooden posts are a landmark in their own right — a visible reminder that this 18 km stage is one link in a 2,600-km chain running the full length of the Alps.
• Wildflower meadows in June and July: The Alm sections explode with Alpine wildflowers in early summer — gentian, arnica, Alpine rose and spotted orchid among them. The colour contrast against limestone grey makes these some of the most photogenic kilometres of the Austrian stages.
• Valley river crossings: Both the start and finish of the stage involve small wooden footbridges over fast-flowing Alpine streams. After snowmelt in May and June, water levels can be high; by August flow is gentle and the bridges are easy crossings.

Best Time to Hike the Via Alpina Purple A13

The hiking season for Stage A13 runs from mid-June to late October, when the mountain passes are reliably snow-free and the Alm huts are staffed. Snow can persist on the ridge crossing into early June, and the first autumn snowfall typically arrives in October, though it rarely closes the route before the end of the month.

July is the single best month for this stage as of 2026. Days are long (16+ hours of daylight), the wildflower display on the high pastures is at its peak, and afternoon thunderstorms — while possible — are less frequent than in August. Temperatures at ridge height (around 1,900 m) average 12–16 °C in July, making the climb comfortable without the heat stress of lower-elevation trails.

June offers solitude and lush green meadows, but snow patches may remain on the north-facing ridge approach and some huts open only from late June. August is peak season: all infrastructure is open, but accommodation books up quickly and the trail is busier. September is an excellent alternative — crowds drop sharply after school resumes, the Alms are still operational through most of the month, and the colours of early autumn on the beech forest descent are outstanding. October is possible for experienced hikers with early starts, but hut closures accelerate mid-month and early snow is a genuine risk from the 15th onward.

Practical Information

Accommodation

The Austrian Via Alpina stages are well-served by the ÖAV hut network, with at least one staffed hut accessible from the high point of most stages. On Stage A13, the primary overnight options are:

• Alpine Hut (Schutzhütte) at high pasture level: Staffed ÖAV or DAV huts near the ridge crossing offer dormitory sleeping (Lager) from approximately €20–28 per person including bedding. Half-board (Halbpension) adds dinner and breakfast for around €45–55 total — strongly recommended as hot food after a full day on the trail is worth every euro.
• Gasthof / Pension in end village: Private rooms in valley Gasthöfe range from €55–90 per person for bed and breakfast. These fill quickly in July and August; book at least 2 weeks ahead for summer weekends.
• Camping: Wild camping is technically prohibited in most Austrian Alpine zones. Designated campsites exist in valley bottoms at the stage ends, typically charging €10–18 per pitch for a tent plus hiker. Facilities are basic but clean.

Getting There & Back

The Austrian Via Alpina stages are accessible by public transport — one of the genuine advantages of hiking in Austria versus many other Alpine countries. The nearest rail connections for the A13 corridor are on the Salzburg–Bischofshofen–Selzthal line, with regional buses (PostBus) covering the final kilometres into the trailhead villages. Allow 1.5–3 hours travel time from Salzburg Hauptbahnhof depending on the specific trailhead. From Innsbruck, travel time via train and bus is similar. The OeBB journey planner at oebb.at handles all rail and integrated bus connections within Austria and is the most reliable tool for planning approach and exit logistics. A point-to-point stage means you arrive and depart from different villages; the bus network typically connects both ends to the same rail line, making a linear walk with public transport return fully feasible without a car.

Permits & Fees

No permit is required to hike Stage A13 or any section of the Via Alpina Purple Trail in Austria. The trail crosses a mix of public land, national park buffer zones and private farmland with right-of-way agreements in place. An ÖAV or DAV (German Alpine Club) membership card entitles holders to discounted hut rates — typically €5–8 less per night than non-member prices — and is worth considering for anyone planning multiple nights in Austrian huts. Annual ÖAV membership costs approximately €65 for adults. There is no trail fee, no day-use charge, and no registration requirement for this stage.

Gear & Packing List

Stage A13's 900 m of cumulative gain and exposed ridge section demand a pack that balances carrying capacity with weight. For hikers doing just this stage or a few days of the Purple Trail, a 35–45 L pack is the sweet spot. For the full multi-week Via Alpina, a 50–65 L pack gives the volume needed for hut-to-hut kit plus emergency layers. See our best ultralight backpacks of 2026 for a tested comparison.

• Backpack (35–45 L): The Deuter Aircontact Lite 45+10 is a proven Austrian-Alps workhorse — the Airflex suspension handles loaded descents without hip-transfer issues, and the 10 L extender gives flexibility for hut-to-hut versus camping configurations. For ultralight-minded hikers, the Zpacks Arc Haul Ultra 50L cuts pack weight dramatically while still handling a full multi-day load.
• Backpack (day / fastpacking): If you are doing A13 as a single day from a valley base, the Deuter Aircontact Core 50+10 or a lighter running vest such as the Salomon ADV Skin 20 handle a day kit with room to spare.
• Footwear: Mid-cut hiking boots with a stiff midsole are strongly recommended for the karst terrain on the ridge section. The limestone pavement is irregular and ankle-twisting in trail runners without lateral support.
• Layers: Ridge temperatures at 1,900 m average 12–16 °C in July but drop fast in afternoon cloud. A lightweight insulating layer (100 wt fleece or down gilet) and a waterproof shell are non-negotiable. See our guide on calorie needs for a full hiking day to fuel the effort properly — 900 m of gain burns significantly more than a flat trail.
• Navigation: Download offline maps before leaving the valley. The purple blazes are reliable but fog can reduce visibility on the ridge to under 20 m. A GPS track backup is prudent.
• Water: Natural water sources (streams and Alm troughs) are frequent in the first two thirds of the stage. Carry 1.5 L minimum from the high pasture section onward as the karst ridge can be dry even in summer.
• Hut reservations: Book mountain huts at least 1–2 weeks ahead in July and August. Most Austrian ÖAV huts now accept online bookings via the alpenverein.at portal.

Frequently Asked Questions

When is the best time to hike Via Alpina Purple A13?
July is the best month as of 2026. The ridge crossing is reliably snow-free, all mountain huts are staffed, wildflowers are at peak display on the high pastures, and daylight runs to over 16 hours. August is also excellent but busier. September is the best choice for avoiding crowds while retaining good conditions. Avoid attempting the stage before mid-June (snow risk on ridge) or after late October (early snowfall, hut closures).

How difficult is Stage A13 of the Via Alpina Purple Trail?
The stage is moderately challenging. The 900 m of cumulative elevation gain demands cardiovascular fitness, and the karst limestone terrain on the ridge requires sure footing and ankle-supportive footwear. There are no via ferrata sections, fixed ropes, or glacier crossings — experienced day hikers comfortable with full mountain days will find it achievable. First-time alpine hikers should be comfortable with a 6–7 hour outing before attempting it.

How far do you hike per day on the Via Alpina Purple Trail?
Stage lengths on the Purple Trail range from 7 km to 35 km, with most Austrian stages averaging 15–22 km and 700–1,100 m of elevation gain. Stage A13's 18 km with 900 m gain is a representative mid-length stage. Most hikers target one stage per day, with rest days or short linking stages built in every 4–5 days for recovery and logistics.

Where do you sleep on the Via Alpina Purple A13?
The main overnight options are ÖAV mountain huts near the high point of the stage (dormitory from ~€20–28 per person; half-board ~€45–55) and Gasthöfe or pensions in the valley villages at either end (private room from ~€55–90 B&B). Wild camping is not permitted in Austrian Alpine protection zones. Huts must be booked in advance for July and August — use the alpenverein.at online booking portal.

Do you need a permit to hike Via Alpina Purple A13 in Austria?
No permit is required. The trail is open to all hikers free of charge. There are no day-use fees, registration requirements, or entry restrictions on this stage. An ÖAV or DAV Alpine Club membership (approximately €65/year for adults) is not mandatory but provides discounts of €5–8 per night at affiliated mountain huts along the route, paying for itself after a few nights.
