Alpe Adria Trail E19

The Alpe Adria Trail E19 is a ~750-kilometre point-to-point trail crossing Austria, Slovenia and Italy in 43 stages, from the foot of the Grossglockner glacier to the Adriatic harbour of Muggia near Trieste. Total cumulative elevation gain is not officially published; the trail is designed for leisure hikers and runs primarily through non-alpine terrain with moderate climbs rather than technical ascents.

About the Alpe Adria Trail E19

The Alpe-Adria-Trail — designated E19 within the International Walking Network (IWN), one of the world's most significant networks of long-distance hiking routes — opened in 2012 as one of Europe's most ambitious cross-border walks. Spanning approximately 750 km across three countries, it links the highest peaks of the Eastern Alps to the northern Adriatic in a single, continuously signposted corridor.

The trail is an official collaboration between three regions: Carinthia (Austria), Slovenia, and Friuli Venezia Giulia (Italy). Each region manages its own section, and together they maintain consistent waymarking, a stage-by-stage accommodation network and a shared trail passport system (Wegpass) that lets walkers collect stamps at each stage end.

What sets the E19 apart from technical Alpine classics is its accessibility without monotony. The trail deliberately avoids sustained high-altitude crossings — it runs mainly through non-alpine terrain — yet the scenery shifts dramatically every few stages. Glacier-carved Carinthian valleys give way to emerald Slovenian river gorges, then to rolling vine terraces and finally the limestone karst that tumbles to the Adriatic. The result is a route that nearly any fit walker can complete, stage by stage, over five to seven weeks.

Expert recommendation: Walk the E19 north to south, starting at the Grossglockner. The most dramatic high-alpine scenery comes first, giving psychological uplift from a spectacular opening act, and you finish with the reward of a warm Adriatic coast. The gradient profile also works in your favour — early stages carry the most ascent; later stages grow progressively gentler as you descend toward the sea. Finishing in Muggia also makes transport logistics easier: Trieste is a major hub with rail connections to Venice, Ljubljana and Salzburg.

Route Overview & Stages

The 43 official stages average approximately 20 km each and take around 6 hours to complete at a steady walking pace. The trail authority recommends staying at stage-end villages to make full use of the accommodation network. The table below shows the four main regional sections; individual stage distances and GPS tracks are published by the official trail authority at alpe-adria-trail.com.

Hikers aiming to complete the full trail in one go should budget 43–50 days at stage pace, including a rest day every 5–7 stages. A common approach is to walk it in two or three separate trips over consecutive years; the well-connected transport network makes virtually any stage-end village a practical starting or finishing point.

Highlights & Points of Interest

• Grossglockner (3,798 m), Austria — Austria's highest peak marks the opening of the trail. The Kaiser-Franz-Josefs-Höhe viewpoint puts you face-to-face with the Pasterze Glacier before you descend into the Mölltal Valley. Even on a cloudy morning the scale of this opening scene sets the tone for everything that follows.
• Hohe Tauern National Park, Austria — The largest national park in the Alps, protecting over 1,800 km² of glaciers, rock faces and alpine meadows. The first eight stages pass through its zone of influence, where ibex graze above the treeline and golden eagles are a regular sight. Hohe Tauern National Park has no entry fee for walkers.
• Heiligenblut, Austria — The first stage-end village of the E19. A picture-perfect Carinthian hamlet built around a Gothic pilgrimage church; the spire appears in nearly every photograph of the Grossglockner massif. An excellent place to book an extra night and rest legs before the descent stages.
• Millstätter See, Carinthia — One of the warmest natural swimming lakes in Austria, sitting at the mid-point of the Austrian section. A stage-end swim here on a hot June afternoon is one of the E19's most instantly rewarding moments after a long walking day.
• Wörthersee, Carinthia — The social heart of Carinthia's lake district. The E19 skirts its shores, passing vineyard-covered slopes and the approaches to Klagenfurt before the trail crosses into Slovenia. The lake district stages are the most leisure-oriented of the entire route.
• Soča River, Slovenia — The translucent turquoise-green Soča is arguably the most photographed single feature on the entire trail. Formed by glacial meltwater and coloured by suspended calcium carbonate, its colour is genuinely unique in Europe, and the gorge through which the E19 passes is unmistakeable.
• Cividale del Friuli, Italy — A UNESCO World Heritage town in Friuli encountered in the Italian section. The Natisone River gorge cuts dramatically through the town, and the Lombard-era stonework and medieval bridges make this the cultural highlight of the Italian stages.
• Muggia Harbour, Italy — The Adriatic finish. Muggia is a small Istrian-influenced town just south of Trieste, and arriving at the harbour front after 750 km on foot is one of the more understated but deeply satisfying finales in European long-distance hiking. The ferry to Trieste across the bay takes under 30 minutes.

Best Time to Hike the Alpe Adria Trail E19

The trail is typically walkable from late May through October. As of 2026, the official season runs from 1 June to 31 October, though the lower-elevation Italian and Slovenian stages can be started two to three weeks earlier in mild years.

June is the single best month to begin the Alpe Adria Trail from the Grossglockner. The high Carinthian passes are reliably snow-free, wildflowers are at their peak in alpine meadows, the lakes have warmed enough for swimming and trail accommodation has not yet filled to the mid-summer squeeze that hits popular Austrian stages in July and August.

• May — The lower Slovenian and Italian stages are hikeable and pleasant, but the Grossglockner start may still carry snow on the first descents. Check conditions with the Carinthia tourist board before committing.
• June — Optimal. Cool mornings in Austria, settled weather in Slovenia, uncrowded Italian stages. Book accommodation for stages 1–8 (Austrian alpine section) at least 4–6 weeks ahead.
• July–August — Warm and busy. The Carinthian lake stages draw leisure tourists who book accommodation months in advance. Possible, but requires planning well ahead for the entire Austrian portion.
• September — Excellent for the Italian and Slovenian sections: lower temperatures, harvest season in Friuli wine country and noticeably quieter than summer. Austrian stages cool quickly; carry an extra insulation layer.
• October — Autumn colour in the forests is beautiful, but days shorten fast. Only experienced mountain walkers should start from the Grossglockner in October; most thru-hikers are finishing, not starting, by this point.

Practical Information

Accommodation

The Alpe Adria Trail is one of the few long-distance routes in Europe with a purpose-built accommodation network covering every single stage. The three regional tourism boards coordinate a shared booking system, and participating hosts display the official E19 trail logo on their properties.

• Gasthofe & mountain huts (Austria, stages 1–8) — Near the Grossglockner, expect mountain guesthouses and huts at €25–45 per person in a dorm, or €50–80 for a private room with breakfast. Book the first two to three stages well in advance for peak summer.
• Carinthian guesthouses (Austria, stages 9–22) — Classic Austrian Gasthofe with Halbpension (half-board) at €40–70 per person. The lake-district stages have the widest choice; prices reflect the tourist popularity of the area.
• Slovenian B&Bs & guesthouses — Slightly cheaper than Austria: €35–65 per person with breakfast. Bovec is the main resupply and overnight hub for the Soča Valley stages; book ahead for July–August.
• Agriturismo & B&Bs (Italy) — Friuli's agriturismo farm-stay network suits the Italian stages perfectly: meals are often included and quality is high. Budget €50–80 all-in. Camping is available at several stage-end villages for around €10–15 per pitch.
• Luggage transfer — Available on many stages through local operators. Costs around €15–25 per stage per bag. Worth considering if you prefer to walk with a daypack rather than a full overnight load.

Getting There & Back

To the start (Grossglockner): Fly into Salzburg (SZG) or Innsbruck (INN) — both are approximately 2 hours by road. From Salzburg, take the train to Zell am See, then a regional bus to Heiligenblut, the closest village to the trailhead with a regular public transport connection. The Grossglockner Hochalpenstrasse runs a seasonal bus in summer that serves the Kaiser-Franz-Josefs-Höhe viewpoint area. Klagenfurt Airport (KLU) is a third option, roughly 2.5 hours by road from the start.

From the finish (Muggia / Trieste): Trieste Airport (TRS) is 35 km from Muggia and handles flights to several European hubs including Frankfurt, Amsterdam and London. By rail, Trieste connects to Venice (2 hours), Ljubljana (2.5 hours) and Salzburg (5 hours), making it straightforward to close the loop back to your starting airport. The passenger ferry from Muggia across the bay to Trieste city centre takes under 30 minutes.

Permits & Fees

The Alpe Adria Trail requires no permit to walk. There is no trail access fee or registration requirement. However, the Grossglockner Hochalpenstrasse — the high-alpine road at the trailhead — charges a vehicle toll (approximately €37 per car); walkers arriving by bus pay nothing. Hohe Tauern National Park has no entry fee for hikers. The official trail passport (Wegpass) is available free of charge from tourist offices along the route and is a popular but entirely optional way to collect stamps at each stage end.

Gear & Packing List

The E19's mix of alpine and coastal terrain demands a versatile kit that holds up across 43 stages. Austrian stages above 1,500 m can turn cold and wet even in June; Italian stages in late September regularly exceed 28°C. Choosing the right pack is central: you need enough capacity for overnight gear across the full route, but light enough that five to seven weeks of walking does not accumulate into chronic fatigue.

For thru-hikers targeting a sub-10 kg base weight, the Hyperlite Mountain Gear 3400 Windrider (680 g) is the go-to choice on multi-week routes: waterproof construction handles alpine rain without a separate cover, and the 54-litre capacity covers a sleeping bag, shelter and 3-day food carry without exceeding ultralight principles. Hikers who prefer a framed suspension system for the heavier Carinthian section should consider the Deuter Aircontact Lite 45+10 (1,570 g), which carries 50-litre loads with considerably less back strain over long days. For section walkers doing the Slovenian or Italian stages over 7–10 days, the Fjallraven Abisko Hike 35 (1,300 g) offers a well-padded 35-litre option that suits the gentler terrain of the southern stages. For a full tested comparison across the ultralight field, see our guide to the best ultralight backpacks of 2026.

Calorie needs over a 20 km walking day on the E19 are significantly higher than most first-time multi-week hikers expect, especially on the uphill Austrian stages. Read our guide on how many calories you burn hiking a full day before building your food plan, particularly if you are using luggage transfer and want to avoid weight surprises.

Core gear checklist:

• Footwear — Mid-height waterproof trail boots for stages 1–8 near the Grossglockner; trail runners are acceptable for Slovenian and Italian stages on dry terrain
• Waterproofs — A packable hardshell jacket is essential; afternoon thunderstorms are common in Carinthia from June through August
• Insulation — Merino base layer and a light down or synthetic jacket for cold mornings near the Grossglockner and for September nights in Friuli
• Navigation — The trail is well-marked throughout, but download offline GPS tracks before you leave; the official Alpe-Adria-Trail app covers all 43 stages
• Sun protection — SPF 50+, a wide-brimmed hat and sunglasses are critical for open Slovenian karst sections and the Adriatic finale in late summer
• First aid & blister kit — Preventive blister care from day one pays dividends over a 43-stage route; pack Leukotape and toe socks

Similar Trails You Might Like

If the Alpe Adria Trail's multi-week scope and point-to-point structure appeal, these trails offer comparable depth across very different landscapes. For dramatically short but intense canyon descents, the South Kaibab Trail (9 km) in the Grand Canyon delivers the same sense of scale compression — immense terrain in a small footprint. The North Kaibab Trail (21 km) extends that experience into a full rim-to-river-to-rim traverse. In Yosemite, the Clouds Rest Trail (15 km) delivers sweeping panoramas directly comparable to the E19's best Carinthian viewpoints, while the Panorama Trail (8 km) links Yosemite Valley's iconic viewpoints in an efficient half-day loop. For those drawn to Adriatic-adjacent mountain crossings, the Theth to Valbona hike in the Albanian Alps is the closest one-day equivalent to the E19's border-crossing spirit — dramatic passes, stone villages and a landscape almost entirely off the mainstream trail radar. Finally, for slot-canyon drama in a very short distance, Hidden Canyon (2 km) in Zion National Park packs surprising adventure into under an hour.

Frequently Asked Questions

When is the best time to hike the Alpe Adria Trail E19?

June is the single best month to begin from the Grossglockner: passes are snow-free, wildflowers are at their peak and accommodation is still available without booking months ahead. The official season runs 1 June to 31 October as of 2026. September is excellent for the Italian and Slovenian stages if you are doing a section trip and want to avoid summer crowds. Avoid starting from the Grossglockner in October unless you are an experienced alpine hiker comfortable with shorter days and early closures.

How difficult is the Alpe Adria Trail E19?

The trail is designed for leisure hikers rather than technical mountaineers. The official description states it runs mainly through non-alpine terrain with moderate elevation changes rather than sustained technical ascents. That said, stages 1–8 near the Grossglockner involve real mountain descent and require appropriate footwear, fitness and weather awareness. The Slovenian and Italian sections are significantly more moderate. Any reasonably fit adult accustomed to walking 15–20 km per day can complete the trail.

How many kilometres per day should I plan to walk?

Each of the 43 official stages averages approximately 20 km and is designed to take around 6 hours at a comfortable hiking pace. Most hikers follow the stage structure precisely, as the accommodation network is built around one stage per day. Combining two stages in a single day is possible on the flatter Carinthian lake and Italian sections but leaves you without planned lodging at the intermediate stage village. A rest day every 5–7 stages is strongly recommended over the full 43-stage route.

What accommodation is available along the trail?

Every stage of the E19 ends at a village or town with participating accommodation. Austrian stages near the Grossglockner offer mountain guesthouses and huts at €25–80 per person. The Carinthian lake stages have guesthouses at €40–70 with breakfast. Slovenia offers B&Bs at €35–65 per person. Italy's agriturismo farm-stays run €50–80 all-in, often including dinner. Luggage transfer is available on many stages for around €15–25 per bag, letting you walk with a light daypack on the more demanding sections.

Do I need a permit to hike the Alpe Adria Trail E19?

No permit is required to walk the E19. There is no trail fee, access charge or registration requirement along the route. The Grossglockner Hochalpenstrasse road toll (approximately €37 per vehicle) applies only to cars — hikers arriving by bus pay nothing. Hohe Tauern National Park charges no entry fee for walkers. The free trail passport (Wegpass), available from tourist offices along the route, is a popular collector's item but entirely optional and not a condition of access.
