Via Alpina Purple A16

The Via Alpina Purple A16 is a 21.7-km point-to-point hiking stage in Styria, Austria, gaining 1,400 m of elevation in around 6 hours 30 minutes. Rated difficulty I on the Via Alpina scale, it climbs from the market town of Eibiswald through forested valleys and open pastures to the Schwanberger-Brendlhütte on the edge of the Koralpe massif — one of Austria's most underrated alpine ranges.

About the Via Alpina Purple A16

The Via Alpina is one of Europe's most ambitious long-distance hiking networks, with five colour-coded routes crossing seven Alpine countries. The Purple Trail (stages A1 to A66) is the easternmost, covering approximately 1,062 km from Trieste on the Slovenian coast to Berchtesgaden in Germany's Bavarian Alps across 66 stages. Stage A16 sits firmly in the Austrian Styrian section, where the landscape transitions from the gentle vineyard-covered hills of southwestern Styria into the raw terrain of the Koralpe — a mountain range that most long-distance hikers discover only by walking through it.

This stage begins in Eibiswald, a quiet market town at roughly 350 m above sea level, surrounded by farmland and positioned close to the Slovenian border. From here, the route makes a sustained ascent of 1,400 m with only 210 m of descent — figures that deserve careful attention before you set off. The Via Alpina rates A16 at difficulty I (basic), which reflects the trail's technical simplicity: paths are wide, clear, and consistently waymarked with the Via Alpina purple diamond. What the rating does not capture is the sheer physical effort of a 1,400-metre climb spread over a single day. Hikers accustomed to Alpine terrain will find this a satisfying full day; those newer to sustained ascents should budget an extra hour and carry more water than they expect to need.

The route character changes markedly across its 21.7 km. The lower section follows valley paths through mixed deciduous forest and past farmsteads, with the gradient easing you into the day. The middle section passes through St. Oswald, a small village sitting at the foot of the Koralpe range with the last reliable opportunity for water and provisions before the climb steepens. Beyond St. Oswald, the trail passes the Kapelle St. Katharina in der Wiel — a small chapel set in a forest clearing that marks the beginning of the alpine approach — before the forest gives way to open mountain pasture and the Schwanberger-Brendlhütte comes into view. The hut sits on the slope leading onto the Koralpe plateau and is where the Purple Trail's character shifts permanently from valley hiking to high alpine travel. The subsequent stage (A17) continues from here to the Koralpenhaus across the plateau ridge, with sweeping views over the Lavanttal valley in Carinthia.

A practical recommendation: walk A16 as published — Eibiswald northward toward the Brendlhütte — and do not reverse the direction. The 1,400 m of ascent is relentless in either direction, but descending the lower forested section in the evening into Eibiswald wastes the most dramatic views, which open up as you climb toward the Koralpe in the morning light. Start no later than 08:00 from Eibiswald: the summit zone is exposed and afternoon thunderstorms are a near-daily occurrence in July and August. Reach the Brendlhütte by 14:00 and you have earned a meal on the terrace with the full Koralpe panorama ahead of you.

Route Overview & Stages

Stage A16 is a single-day hike of 21.7 km and 1,400 m of ascent, the confirmed figures from the official Via Alpina route data. The table below shows A16 alongside the subsequent stage for planning context.

Route waypoints on A16 (south to north): Eibiswald (market town, rail access, ~350 m) → valley forest and farmland → St. Oswald (village church, last provisions) → Kapelle St. Katharina in der Wiel (chapel waypoint, upper forest edge) → open alpine meadow zone → Schwanberger-Brendlhütte (staffed hut, end of stage, Koralpe plateau). The 1,400 m of ascent is distributed across the full 21.7 km, with the steepest gradient concentrated in the upper third of the route above the chapel waypoint.

Highlights & Points of Interest

• Eibiswald — The stage start: a compact market town in southwestern Styria close to the Slovenian border. It has a main square, bakeries, and a supermarket, and it is served by regional rail from Graz — making it the most practical entry point for through-hikers joining or rejoining the Purple Trail in this section.
• Weststeiermark vineyard landscape — The lower slopes around Eibiswald fall within the Weststeiermark wine-growing region, known for Schilcher rosé produced from the Blauer Wildbacher grape. This distinctly southern-Austrian agricultural character contrasts sharply with the high alpine terrain above, giving A16 an unusually wide landscape arc across a single day.
• St. Oswald — A tranquil village at the foot of the Koralpe range, anchored by a historic parish church. This is the last reliable stop for water refills and any provisions before the climb intensifies, and it marks the natural boundary between valley walking and mountain hiking on A16.
• Kapelle St. Katharina in der Wiel — A small wayside chapel in a forest clearing on the upper approach. Its position signals that the trail has definitively left cultivated land and entered the alpine zone of the Koralpe, and it serves as a natural psychological milestone on the long ascent toward the Brendlhütte.
• Koralpe massif — One of Austria's longest north-south mountain ranges, forming the natural boundary between Styria and Carinthia. The plateau reaches 2,140 m at the Großer Speikkogel and is characterised by open, treeless ridgelines with wide-open views east over Styria and west over the Lavanttal on clear days.
• Schwanberger-Brendlhütte — The stage endpoint and a staffed alpine hut offering food, drinks, and dormitory accommodation. It marks the first genuine high-alpine staging post on this section of the Purple Trail and is where the Koralpe plateau opens fully into view for the next day's walking.
• Via Alpina waymarking system — Stage A16 is marked throughout with the Via Alpina purple diamond, one of the most consistently maintained long-distance trail markings in the Alps. Signs are frequent enough that navigation is reliable without GPS in good weather, though a 1:25,000 topographic map remains recommended above the treeline.
• Trans-national trail context — A16 is one segment of a 1,062-km route spanning Slovenia, Austria, and Germany. Long-distance hikers completing the full Purple Trail pass through this stage roughly 15–16 days into the Austrian section from the Slovenian border at Lavamünd — a position that gives A16 a certain mid-journey, finding-your-feet significance on a multi-week traverse.

Best Time to Hike the Via Alpina Purple A16

The hiking window for A16 runs from late May to early October, with the season opening date governed by snow clearance on the upper slopes above St. Oswald. Late May and early June can see lingering snowfields above 1,400 m and occasional closures of the direct approach to the Brendlhütte; trail conditions in those months should be confirmed with the hut by phone before departure.

July is the single best month to hike stage A16. Snow has cleared from all route sections, the Schwanberger-Brendlhütte is fully staffed, alpine wildflowers are at peak colour across the Koralpe meadows, and morning temperatures in the valley are comfortable for a sustained 6.5-hour ascent. Afternoon thunderstorms are a regular feature on the Koralpe from June through August — plan early starts aiming to reach the hut by 14:00 at the latest.

September is a rewarding alternative: trails are noticeably quieter, early-autumn anticyclones bring stable clear weather, and the contrast of yellowing grasses and the first larch colour on the upper slopes is visually striking. As of 2026, the Alpine season in this part of Styria follows the broader trend of drier springs and wetter early-summer periods; check the Austrian weather service (ZAMG) forecast for Weststeiermark the evening before departure. October is technically possible but the Brendlhütte closes for the season — verify the exact closing date with the hut before committing to a late-season visit.

Practical Information

Accommodation

The Schwanberger-Brendlhütte is a staffed Austrian Alpine Club (ÖAV) hut and the natural overnight stop at the end of stage A16. It offers dormitory-style sleeping (Matratzenlager) and half-board. ÖAV members receive a substantial discount on overnight fees; non-members pay the standard Fremdentarif. As a planning benchmark, Austrian Alpine Club huts in this category typically charge €25–35 per person for a dormitory bed and €40–55 for half board — confirm exact rates directly with the Brendlhütte for the 2026 season when booking. The hut has limited bed capacity and fills quickly on weekends in July and August: book ahead by phone or email, particularly for Friday and Saturday nights during peak season.

For hikers who prefer valley-based accommodation, Eibiswald has a small number of guesthouses (Pensionen), and the village of St. Oswald also has lodging options at the foot of the climb. This allows A16 to be walked as a day hike from valley accommodation, though the hut experience at the Brendlhütte — and the direct continuation to stage A17 the following morning — is what most Purple Trail through-hikers choose.

Getting There & Back

Eibiswald is served by the Weststeiermarkbahn regional rail line from Graz Hauptbahnhof. Alight at Wies-Eibiswald station; the journey from Graz takes approximately 1 hour 10 minutes with trains at roughly two-hour intervals. Check timetables and book in advance for peak summer weekends at oebb.at.

By car from Graz, Eibiswald is approximately 55 km via the A2 Südautobahn and the B76 regional road, with limited parking in the town centre. Note that the Schwanberger-Brendlhütte is not road-accessible — it is reached only on foot. Point-to-point through-hikers continuing beyond A16 will need to plan onward transport from wherever they end their hiking section, or commit to a full end-to-end traverse of the Purple Trail.

The nearest international airport is Graz Airport (GRZ), approximately 65 km from Eibiswald, with direct connections to Vienna, Frankfurt, Munich, and Zürich. Klagenfurt Airport in Carinthia is an alternative for hikers approaching the Koralpe section from the north or completing the trail in reverse.

Permits & Fees

No permits are required to hike stage A16 of the Via Alpina in Austria. The trail crosses farmland and forest under established right-of-way agreements maintained by the Via Alpina network and local alpine clubs. There is no trail fee, registration system, or entry charge for this stage. ÖAV (Austrian Alpine Club) membership is optional but reduces overnight costs significantly at all huts along the Purple Trail; annual adult membership costs approximately €68 and pays for itself quickly on a multi-week traverse.

Gear & Packing List

Stage A16 is a single day with 1,400 m of sustained ascent and a staffed hut at the end. The packing equation for hut-to-hut hiking is straightforward: carry only what you need for the day, because every unnecessary gram becomes apparent on the upper third of that climb. A pack in the 20–35 litre range is optimal for a Purple Trail hut-to-hut configuration.

The Hyperlite Mountain Gear Aero 28 (536 g) is exceptionally well-suited to this style of hiking — it carries a complete hut kit comfortably while keeping base pack weight negligible, a real advantage over 1,400 m of gain. For hikers who prefer conventional Alpine frame support and carry heavier loads between huts, the Deuter Aircontact Lite 45+10 (1,570 g) offers outstanding back ventilation and load transfer on sustained ascents. Those who travel at the lightest end will find the Salomon ADV Skin 20 (395 g) keeps the pack entirely off the back on hot July ascents and covers all the volume needed for a single day stage. For a broader comparison of lightweight options for Alpine hiking, see Best Ultralight Backpacks 2026: 7 Sub-1 kg Packs Tested.

Beyond the pack, the non-negotiable items for A16 are: a waterproof jacket (afternoon thunderstorms are a routine feature on the Koralpe from June through September), trekking poles for the descent if you plan to return the same day, at least 1.5 litres of water topped up at St. Oswald where there is no resupply until the Brendlhütte, a warm mid-layer for the hut's exposed ridge position, and a solid snack reserve for the upper section above the treeline. A16's 1,400-metre ascent burns significantly more energy than a flat day suggests — read our guide on how many calories you need hiking a full day to calibrate your food carry before you leave Eibiswald.

Similar Trails You Might Like

Stage A16 opens the door to the Koralpe and the Styrian-Carinthian highlands — a section of Austria that sees a fraction of the crowds found in the Tyrol or Salzburg Alps. If the hut-to-hut, high-alpine character of the Purple Trail appeals, the Stubaier Höhenweg (85 km, Austria) is the natural next challenge: a full traverse of the Stubai Alps with comparable daily elevation demands and excellent hut infrastructure. For shorter taster routes in the Austrian Alps, the Adlerweg (Austria) covers a memorable section of Tyrolean highland trail, while the Berliner Höhenweg Zustieg Ahornbahn (2 km, Austria) offers a scenic approach to the celebrated Berliner Höhenweg circuit in the Zillertal. Regional loops near the Koralpe include JK01 (32 km, Austria) and JK02 (34 km, Austria), both suitable for hikers who want to explore the broader Styrian-Carinthian network after completing A16. For a very different kind of demanding single-day mountain crossing — wild rather than hut-based — the Theth to Valbona hike in Albania offers comparable physical intensity in a dramatically different setting.

Frequently Asked Questions

What is the best time of year to hike the Via Alpina Purple A16?

July is the optimal month for stage A16. Snow clears reliably from all sections by late June, the Schwanberger-Brendlhütte is fully staffed and bookable, and the alpine wildflowers on the Koralpe approach are at their peak. June is viable but requires confirming trail conditions with the hut in advance. September offers quieter trails, stable anticyclonic weather, and the first autumn colours on the Koralpe plateau. Avoid October and beyond when the Brendlhütte closes for the season.

How difficult is the Via Alpina Purple A16?

Stage A16 is rated difficulty I (basic) on the Via Alpina scale, meaning the path is technically straightforward throughout — wide, well-marked, with no scrambling or exposed sections. However, the 1,400 m of elevation gain over 21.7 km makes this a physically demanding day that should not be underestimated. The difficulty I rating reflects route complexity, not aerobic intensity. Hikers without regular uphill training should budget 7–8 hours rather than the published 6h30 and plan an early start.

How many kilometres per day is the Via Alpina Purple A16?

Stage A16 covers 21.7 km in a single day — one of the longer stages by distance on this section of the Purple Trail. The 1,400 m of elevation gain means pace drops significantly on the upper third of the route. Most hikers cover the valley sections through St. Oswald at a steady pace, then slow noticeably on the alpine approach above the treeline. Plan for a six- to seven-hour active hiking day including rest stops and a meal break at St. Oswald.

Where do you sleep on the Via Alpina Purple A16?

The standard overnight stop is the Schwanberger-Brendlhütte, a staffed Austrian Alpine Club hut at the end of stage A16, offering dormitory accommodation (Matratzenlager) and half-board meals. ÖAV members receive a discount on hut fees; non-members pay the standard guest tariff. The hut fills quickly on summer weekends — book ahead directly with the Brendlhütte by phone or email. Hikers preferring valley accommodation can stay in Eibiswald or St. Oswald and complete A16 as a day hike.

Do you need a permit to hike the Via Alpina Purple A16?

No permit is required for stage A16 in Austria. The route crosses farmland and forest under established right-of-way agreements maintained by the Via Alpina network and local alpine clubs. There is no entry fee, trail pass, or registration system for this stage. ÖAV (Austrian Alpine Club) membership is optional but meaningfully reduces overnight costs at huts across the entire Purple Trail and pays for itself after two or three hut nights on a multi-stage hiking trip.
