Alta Via dell'Adamello-Tappa 7 (Tonolini-Garibaldi)

The Alta Via dell'Adamello – Tappa 7 (Tonolini–Garibaldi) is an 8-km point-to-point trail in Lombardy, Italy, gaining roughly 710 m of elevation across a single demanding day. Rated EE (for experienced hikers), it crosses Passo Premassone at 2,923 m — the highest point of the entire Alta Via — linking two CAI mountain huts through a wild, glacier-scoured granite wilderness.

About the Alta Via dell'Adamello-Tappa 7 (Tonolini-Garibaldi)

Stage 7 is one of the most spectacular and technically serious links of the Alta Via dell'Adamello — also catalogued as Sentiero Numero 1 dell'Adamello — a long-distance traverse through the granite massif that rises between the Valle Camonica and the upper Val di Genova in the Italian central Alps. This particular tappa runs roughly 8 km (some GPS tracks measure 8.6 km) from Rifugio Tonolini at 2,450 m to Rifugio Garibaldi at 2,550 m, and although the start and finish altitudes are almost identical, the day demands around 710 m of climbing and 610 m of descent because the route vaults over a high rock barrier in between.

That barrier is Passo Premassone (2,923 m), the single highest point reached anywhere along the full Alta Via. The terrain here is uncompromising: large granite boulder fields, zig-zagging stone paths, and steep sections protected by fixed chains and short metal ladders. This is not a gentle valley walk. The stage is rated impegnativo (demanding) in Italian grading and corresponds to the Club Alpino Italiano EE classification — Escursionisti Esperti, meaning experienced hikers comfortable on exposed, unstable ground.

The route is maintained as part of the regional walking network and falls within the Parco Regionale dell'Adamello, a 510 km² protected area established in 1983 on the Lombardy side of the massif. The huts along the way are operated under the umbrella of the Club Alpino Italiano (CAI), the national mountaineering body that manages the alpine refuge system. For hikers tackling the Alta Via in sequence, Tappa 7 is frequently described as the emotional and physical crux of the whole journey — the day you stand on the watershed of the Adamello and look across to its summit glaciers.

Route Overview & Stages

While Tappa 7 is itself a single stage of the longer Alta Via, it breaks naturally into distinct sections defined by the lakes, the pass, and the final hut approach. The table below outlines those internal segments with approximate distances and climbing.

Plan on roughly 5 hours of moving time, or 6–7 hours with photo and lunch stops. There is no escape route or intermediate shelter once you commit to the climb toward Passo Premassone, so an early start and a firm turnaround time are essential. Hut-to-hut planners using our Theth to Valbona guide will recognise the same logistics challenge of stringing high alpine refuges together with no road access in between.

Highlights & Points of Interest

• Passo Premassone (2,923 m) — the literal summit of the Alta Via, a narrow rock col with panoramic views back over the Baitone lakes and forward toward the Adamello glacier.
• Lago Rotondo — a circular tarn near the start, mirroring the surrounding granite walls; one of more than a dozen lakes in the dam-rich Baitone basin.
• Lago Premassone — a higher, colder lake passed on the long climb toward the pass, often holding snow patches into July.
• Lago del Pantano (2,378 m) — the low point of the stage, where a hydroelectric dam wall marks the bottom of the chain-assisted descent.
• Bocchetta del Pantano / Passo del Lunedì (2,650 m) — the second col of the day, a rocky notch that opens the final view toward Rifugio Garibaldi.
• Chiesetta della Madonna dell'Adamello (2,530 m) — a tiny stone chapel built in 1917 during World War I, standing near the hut as a memorial to the Alpine troops who fought the "White War" on these glaciers.
• Rifugio Garibaldi (2,550 m) — the historic CAI refuge above Lago di Venerocolo, a base for climbers heading onto the Adamello summit (3,539 m).
• Fixed chains and ladders — the protected steps on the descent from Passo Premassone are a highlight in their own right, demanding focus but adding genuine high-mountain character.

Best Time to Hike the Alta Via dell'Adamello-Tappa 7 (Tonolini-Garibaldi)

The viable window for this stage runs from late June to late September, with the broader season sometimes quoted as April to October for the lower approaches. Because Passo Premassone tops out at 2,923 m, snow lingers on the north-facing chain section well into early summer, and the steps become genuinely dangerous when iced or wet.

The single best month is August, and into early September. By then the snow has cleared from the pass, daytime temperatures at hut altitude sit around 10–18 °C, and the huts are fully staffed. As of 2026, snowpack across the central Italian Alps has been variable, so check the latest conditions with the refuges before committing — a heavy winter can leave hard névé on the descent into July. July is also good but can be busier and more thunderstorm-prone in the afternoons; aim to clear the pass before midday. Late September offers crisp air and quiet trails, but huts begin closing around the third week and the weather grows unsettled. Avoid the shoulder months entirely unless you are equipped and competent for snow and ice on exposed terrain.

Practical Information

Accommodation

This is a hut-to-hut stage, so the two CAI refuges at either end are your accommodation. Rifugio Tonolini (2,450 m, also written Rifugio Tonolini al Baitone) and Rifugio Garibaldi (2,550 m) both offer dormitory bunks and a kitchen. Expect to pay roughly €25–30 for a dormitory bed (CAI members receive a discount of around 50%), plus about €30–40 for half board (dinner and breakfast). Bring cash — card payment is unreliable at this altitude. Booking ahead is essential in August; the huts have limited beds and fill fast on weekends.

Wild camping is restricted inside the Parco Regionale dell'Adamello, though experienced hikers sometimes bivouac discreetly above 2,500 m for a single night. If you carry a tent, do so as a backup only and leave no trace. Nearby alternatives in the Baitone basin include Rifugio Gnutti and Rifugio Baitone, which some itineraries use as the stage start instead of Tonolini.

Getting There & Back

The gateway is the Valle Camonica on the Lombardy side. The nearest railway station is Edolo, the terminus of the Brescia–Iseo–Edolo regional line, about 2.5–3 hours by train from Brescia. From Edolo, local buses and taxis serve the village of Sonico and the trailhead access roads up toward the Baitone valley; the final approach to Rifugio Tonolini is itself a multi-hour walk from the highest car park, so most hikers reach the hut on the preceding stage rather than in a single day from the valley.

The nearest major airports are Bergamo–Orio al Serio (BGY), roughly 2.5 hours by car, and Verona (VRN) or Milan Bergamo for international arrivals. Driving is the most practical option for reaching the trailhead car parks; from Bergamo allow about 2 hours to Sonico via the SS42.

Permits & Fees

No permit is required to hike the trail itself — access to the Parco Regionale dell'Adamello is free for walkers. There are no toll gates on the path. Your only costs are hut fees, food, and any parking charges at the valley trailheads. CAI membership is worth considering if you plan several hut nights, as the discount quickly offsets the annual fee. Check current hut opening dates and any seasonal access restrictions with the park and the refuges before you travel.

Gear & Packing List

Tappa 7 demands proper alpine kit, not casual day-hiking gear. The chain-protected descent rewards sure footing, so prioritise stiff-soled boots with aggressive lugs and consider a lightweight via-ferrata glove for hand protection on the cables. Trekking poles help on the long boulder-field climb but should be stowable for the hands-on sections.

For a multi-day Alta Via traverse you want a 45–60 litre pack that carries weight comfortably over rough ground. Good options include the Arc Haul Ultra 60L for ultralight hut trips, the supremely supportive Osprey Atmos AG 50, or the rugged Deuter Aircontact Core 50+10 when you are carrying camping backup. If you are weighing up which pack suits a hut-based route, our roundup of the best ultralight backpacks of 2026 compares seven tested models head to head.

• Layered insulation: high passes are cold and windy even in August
• Waterproof shell and trousers — afternoon thunderstorms are common
• 2–3 litres of water capacity; refill at huts and clean lake inlets
• Headlamp, map, compass and a charged phone with offline GPS
• Sun protection: UV is intense above 2,500 m
• High-calorie trail food — see how many calories you need hiking a full day to plan portions for 700 m of climbing

Frequently Asked Questions

When is the best time to hike Tappa 7? August is the single best month, with the broader window running from late June to late September. By August the snow has cleared from the chain-protected descent off Passo Premassone, hut staff are fully present, and temperatures at 2,500 m sit around 10–18 °C. July works too but brings more afternoon thunderstorms, so clear the high pass before midday.

How difficult is the Tonolini–Garibaldi stage? It is demanding and rated EE (for experienced hikers) by the Club Alpino Italiano. The route crosses Passo Premassone at 2,923 m over steep boulder fields, with fixed chains and short ladders on the descent. There is real exposure, and the protected steps are dangerous when wet or iced, so good footing and a head for heights are essential.

How far is the stage and how long does it take? The stage covers about 8 km (some GPS tracks read 8.6 km) with roughly 710 m of ascent and 610 m of descent. Despite the short distance, the rough granite terrain and the climb to 2,923 m mean it takes around 5 hours of moving time, or 6–7 hours including stops and the technical chain sections.

Where do I sleep on this route? The stage links two CAI mountain huts: Rifugio Tonolini (2,450 m) and Rifugio Garibaldi (2,550 m). Dormitory beds cost roughly €25–30, with half board adding €30–40; CAI members get about 50% off the bed fee. Book ahead in August and carry cash, as card payment is unreliable at altitude. Wild camping is restricted within the park.

Do I need a permit or pay any fees? No permit is required to walk the trail, and entry to the Parco Regionale dell'Adamello is free for hikers. Your only costs are hut fees, food, and parking at the valley trailheads. CAI membership pays for itself over several hut nights through the discounted bed rate, so consider joining if you are hiking the wider Alta Via.
