Alpe Adria Trail E35

The Alpe Adria Trail E35 is an approximately 750-kilometre point-to-point trail crossing Austria, Slovenia and Italy — from the foot of the Grossglockner (3,798 m) to the Adriatic coast at Muggia near Trieste. Completed across 43 official stages over 28 to 43 days, it descends more than 3,700 metres in net elevation and is rated moderate to challenging, making it one of Europe's most scenically diverse alpine-to-coast long-distance routes.

About the Alpe Adria Trail E35

The Alpe Adria Trail carries the European long-distance walking designation E35, placing it among the continent's most significant hiking routes under the International Walking Network (IWN). Developed collaboratively by the regions of Carinthia (Austria), Slovenia and Friuli Venezia Giulia (Italy) and officially opened in 2012, the trail has since become one of the best-supported multi-day walking routes in the Alps — notable not just for its scenery but for its infrastructure: consistent waymarking, luggage transfer services on most stages, and accommodation at every overnight stop.

The route begins at Laced (Latscher Alm) beneath the Grossglockner — Austria's highest peak at 3,798 m — and travels south through glaciated alpine terrain, past some of Carinthia's most beautiful lakes, across the Julian Alps into Slovenia's Soča Valley, and finally through the rolling wine hills and karst plateaus of Friuli before reaching the sea at Muggia on the Gulf of Trieste. Each of the 43 stages has a defined start and finish village with full waymarking throughout.

Direction recommendation: walk north to south. The prevailing weather systems in the eastern Alps push from west and north, so heading toward the Mediterranean means you are generally walking into improving conditions. The psychological arc matters too — from glacial grandeur to Roman ruins to an Adriatic seafront is a satisfying narrative that works in one direction only. Walking it south to north requires a 3,700 m net climb and ends in alpine cold rather than warmth. There is no good reason to reverse the route unless you have a specific logistical constraint.

The E35 is also one of the most logistically friendly long-distance alpine routes in Europe. A luggage transfer service operates on most stages, allowing you to walk with a daypack while your main bag is shuttled ahead. This particularly suits the Carinthian stages, where mountain terrain demands careful load management. Hikers who carry full packs typically aim for a base weight of 8–12 kg; see the gear section below for options across the weight spectrum.

Route Overview & Stages

The 43 stages are grouped across three country sections. Official per-stage distances range from 10 to 29 km, with elevation gain per stage varying significantly — the early Austrian alpine stages are steep and demanding, while the Italian coastal stages are gentle. The table below summarises the three main sections; for the complete 43-stage breakdown with exact distances and elevation profiles, consult the official Alpe Adria Trail stage guide.

The Austrian section is the most physically demanding. Stages 1 through 4 involve serious alpine terrain through the Hohe Tauern National Park — the largest national park in the Alps at 1,856 km². If fitness or time is a concern, joining the trail at Hermagor (around Stage 7) lets you skip the highest alpine stages while retaining Carinthia's famous lake district. That said, the Hohe Tauern stages are the route's most spectacular — skipping them is a reasonable compromise only if the alternative is not doing the trail at all.

Highlights & Points of Interest

• Grossglockner & Hohe Tauern National Park, Austria — The trail's dramatic opening, flanked by glaciers and Austria's highest summit. The national park covers 1,856 km² of protected alpine wilderness with marked paths, mountain huts and ranger infrastructure. The Hohe Tauern National Park operates huts on the early stages and is the reference point for current conditions and closures.
• Millstätter See, Carinthia — One of Austria's warmest and cleanest alpine lakes, ringed by forested hills. The Alpe Adria Trail crosses the southern shore — a welcome stage for swimming after the hard alpine opening, and one of the few places on the route where most hikers slow down voluntarily.
• Wörthersee, Carinthia — The largest of the Carinthian lakes and arguably the most beautiful. The trail passes through Velden and continues toward Klagenfurt, the provincial capital, which makes a logical rest day with full services, rail connections and accommodation options across all budgets.
• Triglav National Park, Slovenia — Slovenia's only national park, centred on the 2,864 m Triglav summit. The trail does not summit Triglav itself but passes through its lower valleys with clear views of the peak. Trail access through the park is free; camping outside designated areas is prohibited.
• Soča River Valley, Slovenia — Renowned for the extraordinary turquoise colour of the Soča, a result of suspended limestone particles. The valley was a World War I frontline; the Walk of Peace trail and numerous memorials run alongside the Alpe Adria route here. Hikers drawn to wild, photogenic mountain valleys in this corner of Europe may also enjoy the character of the Theth to Valbona hike in Albania — comparable drama in a more remote setting.
• Cividale del Friuli, Italy — A UNESCO World Heritage Site for its Lombard-era archaeological remains. The town's Tempietto Longobardo, the Natisone River canyon and a well-preserved medieval centre make this the most culturally dense overnight stop on the Italian section and one of the few towns where an extra night is worth considering.
• Grado Lagoon, Friuli — The trail's transition to the Adriatic world. The shallow lagoon is a protected wetland and bird reserve. The approach to Grado across a 7 km causeway with water on both sides is one of the most unusual and atmospheric final approaches on any European long-distance route.
• Muggia — the finish — A small Venetian-influenced fishing town on the Gulf of Trieste. The arrival is quiet and unhurried. Trieste city centre is 10 km north by bus and rewards a day's exploration as a post-trail destination before the journey home.

Best Time to Hike the Alpe Adria Trail E35

The trail is officially open from June to October. Snow can linger on the highest Carinthian stages well into May, and mountain huts in Austria typically open in mid-June. As of 2026, the official season for trail infrastructure — luggage transfer, hut accommodation, full waymarking maintenance — runs from mid-June through late September.

• June: Early-season freshness with wildflowers on the alpine meadows and high rivers in the Soča Valley. Higher chance of afternoon thunderstorms in Carinthia. Some huts are newly opened and less crowded, but a late start risks encountering residual snow on Stages 1–4. Recommended only for experienced alpine hikers starting after 15 June.
• July–August: Peak season. Long daylight hours, reliable warm weather through Italy, and the Carinthian lakes reach swimmable temperatures (Wörthersee peaks at around 28°C in August). Book mountain huts at least 4–6 weeks in advance — the Austrian section fills quickly, particularly around weekends and Austrian public holidays.
• September: The single best month to walk the Alpe Adria Trail. Crowds drop significantly after the first week, temperatures are comfortable for walking (18–24°C in the valleys, 8–14°C at altitude), visibility is excellent and the vineyards of Friuli are in harvest — the final Italian stages have a particular warmth and character that July and August cannot match. Huts remain open through late September; booking a week or two ahead is sufficient rather than months.
• October: Possible but risky. Huts begin closing from 1 October. Early snow on the alpine stages is plausible after mid-October, and shorter days limit flexibility. Only viable for the Slovenian and Italian sections as a standalone option.

Best month: September. If you can only go once, go in September.

Practical Information

Accommodation

The trail is served by a dense accommodation network across all 43 stages — one of its strongest practical advantages over more remote long-distance routes.

• Alpine huts (Carinthia, Stages 1–7): Austrian Alpine Club (ÖAV) huts charge approximately €20–35 per person in dormitory (Lager) and €35–60 in private rooms. Half-board (dinner and breakfast) typically runs €45–70. ÖAV membership gives a 50% discount on hut fees and is worth obtaining before departure if you plan to stay in more than five or six huts.
• Guesthouses & Gasthöfe (Carinthia and Slovenia): Widely available at lake villages and town stages. Expect €50–90 per person bed and breakfast.
• Agriturismo (Friuli, Stages 22–43): Family-run farm stays are plentiful through the wine country and often provide the best-value accommodation on the entire route, typically €45–70 per person including breakfast and occasionally dinner.
• Luggage transfer: Bookable through the official trail organisation on most stages. Allow €10–15 per bag per stage. Book at least the night before; some operators require 48 hours' notice in peak season.

Getting There & Back

Starting point — Grossglockner area, Austria: The closest major transport hub is Salzburg Airport (SZG), approximately 1.5 hours by rail to Zell am See, from where seasonal shuttle buses serve the Grossglockner area. Innsbruck Airport (INN) is roughly 2 hours by rail and bus. The trailhead at Laced (Latscher Alm) is accessed by a seasonal shuttle from Franz-Josefs-Höhe — check current 2026 timetables via the Nationalpark Hohe Tauern service.

Finishing point — Muggia, Italy: Muggia is served by Bus Line 20 from Trieste (approximately 25 minutes, around €2). Trieste has direct rail connections to Venice (2 hours), Ljubljana (3 hours) and Vienna (6 hours). Trieste Airport (TRS) is 35 km northwest with connections to Rome, Frankfurt and Amsterdam. Venice Marco Polo Airport (VCE) — 2.5 hours by train — offers significantly more international routes and is the practical choice for most non-European visitors flying home.

Permits & Fees

No hiking permit is required to walk the Alpe Adria Trail. However:

• The Hohe Tauern National Park (Stages 1–4) is a protected zone requiring hikers to stay on marked paths. There are no entry fees, but camping outside designated areas is strictly prohibited.
• Triglav National Park (Slovenia, Stages 14–16) similarly requires no trail permit but has strict wild camping restrictions throughout. Open fires are not permitted anywhere in the park.
• The official Alpe Adria Trail app (free) and paper stage maps (€3–5 per section) are available via the official website and regional tourist offices. Neither is compulsory, but the app is a practical backup in Slovenia where signage can use Slovenian-only place names.

Gear & Packing List

The Alpe Adria Trail spans alpine, river-valley and coastal terrain across up to 43 days, making pack weight a serious consideration. A pack in the 45–65 L range suits hikers carrying a tent; a 20–35 L daypack is sufficient if you use the luggage transfer service and book accommodation on every stage.

For thru-hikers using huts and guesthouses without luggage transfer, the Zpacks Arc Blast 55L (450 g) is the lightest viable option on this route — its frameless cuben fibre construction is exceptional for weight-conscious hikers targeting a 6–8 kg base weight. For more structure and robust alpine weather protection, the Hyperlite Mountain Gear 3400 Windrider (680 g) handles Carinthian thunderstorms without compromising significantly on weight.

If you plan to use luggage transfer on most days, the Deuter Aircontact Lite 45+10 (1,570 g) is the most sensible comfort choice — its ventilated back system handles heavier multi-week kit well across varied terrain. For stage-only daypacks, the Hyperlite Mountain Gear Aero 28 (536 g) or Salomon ADV Skin 20 (395 g) carry a day's essentials and a light layer without effort.

Other essentials for the Alpe Adria Trail:

• Waterproof jacket: Mandatory for alpine stages. Carinthian afternoon thunderstorms build quickly and offer little warning — a packable hardshell is not optional on Stages 1–8.
• Trekking poles: The steep descents on the early Austrian stages and some Italian karst sections make poles worthwhile, especially with a loaded pack.
• Sun protection: Italian stages in July–August are exposed and frequently exceed 30°C. SPF 50 sunscreen and a light sun hat are essential from Stage 22 onward.
• Nutrition planning: Daily energy demands on longer stages can reach 4,000–5,000 kcal. The Friuli section has fewer reliable mid-stage food stops than the Austrian section — plan accordingly. Our guide to how many calories you need hiking a full day covers the calculation in detail.
• Navigation: The official app (free download from the trail website) is the practical backup, especially through Slovenia.

Frequently Asked Questions

What is the best time to hike the Alpe Adria Trail E35?

September is the single best month. Temperatures are comfortable for walking (18–24°C in the valleys), mountain huts remain open and are significantly less crowded than in July or August, and the harvest season adds atmosphere to the Friuli wine-hill stages. The official season runs mid-June through late September; the Austrian alpine stages can hold snow into early June, making a start after 15 June the earliest reliable option for most hikers.

How difficult is the Alpe Adria Trail?

The trail is rated moderate to challenging overall, but difficulty varies considerably by section. The Austrian alpine stages — Stages 1 through 4 in particular — involve steep ascents and high-mountain terrain requiring solid hiking fitness, layered clothing and appropriate footwear. The Slovenian and most Italian stages are considerably gentler. The 43-stage thru-hike is a commitment of endurance rather than technical skill; no ropes or mountaineering equipment are required at any point on the marked route.

How far do you walk each day on the Alpe Adria Trail?

Official stage distances range from approximately 10 to 29 km per day, with most stages falling in the 15–22 km range. Alpine stages tend to be shorter in distance but longer in time due to elevation changes. A standard thru-hike pace covers one stage per day, completing all 43 stages in approximately 43 days. Many walkers combine shorter stages or take scheduled rest days, extending the total trip to five or six weeks.

Is accommodation available on every stage of the Alpe Adria Trail?

Yes. The E35 is one of the best-supported long-distance walking routes in Europe, with guesthouses, mountain huts or agriturismo accommodation at the end of every official stage. Austrian mountain huts must be booked 4–6 weeks ahead in July and August. A luggage transfer service operates on most stages, letting you walk with a daypack while your main bag is moved ahead — ideal for hikers who want to cover the full route without the physical burden of a loaded pack on alpine terrain.

Do you need permits to walk the Alpe Adria Trail?

No hiking permit is required to walk the trail. The route passes through Hohe Tauern National Park in Austria and Triglav National Park in Slovenia, both freely accessible on marked paths, but camping outside designated areas is prohibited in both parks. There is no trail registration system or fee. The official Alpe Adria Trail app and stage maps are strongly recommended but not compulsory — the trail is consistently waymarked throughout all three countries.
