Why the Grigna Settentrionale is Worth the Climb
The Grigna Settentrionale (2,409m / 7,903 ft), commonly known as the Grignone, is the highest peak in the Lombardy Prealps and the defining landmark above Lake Como. Its pale limestone ridges and spires dominate the skyline from Varenna, Lecco, and the eastern shore — a constant presence that rewards the effort of the ascent with one of the finest panoramas in all of northern Italy.
From the summit on a clear day, the view is genuinely breathtaking: the two branches of Lake Como spread out below, the full sweep of the Alps from Bernina to Monte Rosa stretches to the north, the Orobie peaks line the horizon to the east, and the Po Valley — with Milan visible on clear days — extends south. There is a reason this mountain has drawn climbers and hikers from across Europe for well over a century.
The limestone you walk on near the summit is Triassic in origin — formed 240 million years ago as marine sediment. The same fossils are on display at the Museo delle Grigne in Esino Lario, just steps from the trailhead. The mountain's dramatic spires, gullies and ridges are shaped by erosion, karst processes and ancient glaciation — the same forces that created the Dolomites further east.
The best approach from Lake Como starts from Esino Lario (914m), a mountain village 30 minutes above Varenna by bus (line SP62). The route follows trail CAI 51 to Rifugio Monza-Bogani (1,816m) and then continues along the exposed final ridge to the summit cross. The total ascent takes approximately 4 hours from Esino Lario, with 1,495m of elevation gain. Rated EE (Experienced Hikers) — not a beginner trail.

La Grigna Settentrionale: montagna simbolo del Lago di Como
La Grigna Settentrionale — chiamata dai locali semplicemente Grignone — è la cima più alta e più imponente delle Prealpi Lombarde. Con i suoi 2409 metri, domina il paesaggio lacustre dell'intera sponda orientale del Lago di Como: visibile da Varenna, da Lecco, da Colico, è un riferimento visivo che accompagna chiunque navighi o passeggi sulle rive del Lario.
Il punto di accesso privilegiato è Esino Lario (914m s.l.m.), borgo montano a 30 minuti di bus da Varenna. Da qui il sentiero CAI 51 sale al Rifugio Monza-Bogani (1816m) in circa 2h30', e dalla forcella sotto il rifugio la cresta finale porta alla vetta in altri 1h30'. Totale salita: 4 ore circa, con 1495 metri di dislivello positivo.

The route
From Esino Lario to the summit
The standard route to the Grigna Settentrionale from Esino Lario follows trail CAI 51 to Rifugio Monza-Bogani, then tackles the final ridge with aided sections. A step-by-step breakdown with precise technical data follows.
Start · Village centre
Esino Lario — Via Roma
From the centre of Esino Lario, take trail CAI 51 heading north, following the signs for "Rifugio Bogani" and "Grigna Settentrionale". The red-and-white waymarks are clearly visible from the main square. The first hundred metres follow a paved secondary road, then the trail enters a chestnut and beech forest. The SP62 bus stop from Varenna is just a few steps from the trailhead.
E — Easy
Tip: leave by 7:00–8:00 AM in summer. Afternoon thunderstorms on the Prealps can arrive as early as 2:00–3:00 PM. Fill up water in the village before departing.
Section 1 · Main ascent
Ascent to Rifugio Monza-Bogani (1816m)
The longest and most demanding section: 3 kilometres of trail with 900 metres of elevation gain. The forest gradually opens up onto alpine pastures and meadows. The trail is well marked but quite steep in places, especially in the final third before the hut. The average gradient is 30%, with steeper sections near the col. The landscape transforms: beeches give way to dwarf pines and then open pastures with the first views of the lake appearing.
EE — Experienced
Physically demanding section. Maintain a steady pace — do not rush the ascent. On wet ground the grassy sections become slippery.
Mandatory stop · Junction
Rifugio Monza-Bogani — Rest and assessment
Rifugio Monza-Bogani (1816m) is the main rest point of the route. Here you stop, refill water, eat something and — crucially — assess the weather conditions with the hut keeper. The hut is also the junction between the normal summit route (CAI 51 continues) and the variant toward the Grignetta (trail heading south). If the sky is not clear and stable, the wise decision is to stop here: the final ridge is exposed.
The hut keeper knows local weather conditions better than any app. Always ask their opinion before proceeding toward the summit. Tel: 368 253 7021.
Technical section · EE
Final ridge to the summit — Aided passages
From the hut you climb to the col and join the final ridge. This is the most technical and spectacular section: pale limestone, exposure on both sides, several aided passages with fixed chains or ropes. The trail is rated EE and requires confidence in alpine terrain, good balance, and stiff-soled boots. In fog or rain this section becomes dangerous: in those conditions, turning back is mandatory.
EEA — Aided route
Fixed chains present. Take them calmly and unhurriedly, using only the necessary holds. Pay extra attention to chains with sweaty or wet-gloved hands.
Goal · Summit
Grigna Settentrionale summit — 2409m a.s.l.
The summit cross of the Grignone (2409m). At the top you will also find the small votive chapel and the summit register where you can leave your name. The panorama is 360°: Lake Como spreads below with its two branches, the Po Valley extends to the horizon to the south, the Alps form an imposing semicircle to the north. On exceptionally clear days you can even see the dome of Milan Cathedral. A moment worth every metre of effort.
At the summit the temperature can be 10–15°C lower than in Esino Lario, even in midsummer. Always pack a warm layer. Ridge wind can be strong.
Descent · Variants
Descent to Esino Lario — Same route or variant
The descent via the same route (CAI 51) takes approximately 2h 45' back to Esino Lario. Pay maximum attention on steep sections and near the aided passages: most mountain accidents happen on the descent, when fatigue reduces concentration. An interesting variant for experienced hikers is the loop descent toward the Mandello side; check the bus timetable before choosing this option.
Do not rush the descent. Use trekking poles for support. If your knees are tired, slow down further. In case of excessive fatigue at altitude: call 112.

Rifugio Monza-Bogani is the heart of the itinerary. Located on a panoramic col at 1816m, it provides an essential rest stop to recharge before the demanding final ridge. The hut serves classic alpine cuisine: minestrone soup, polenta with local cheeses, canederli (bread dumplings), and sandwiches with cured meats. In summer, the outdoor terraces are an ideal rest point with views over Lake Como.
The hut is open from approximately June to October, with possible variations depending on weather conditions. On July and August weekends the hut is very busy: booking is required for overnight stays. For lunch at the hut it is advisable to contact the hut keeper the day before. The hut also provides drinking water — essential for filling bottles before tackling the final ridge.

Frequently asked questions
Everything you want to know about the Grigna
ENHow hard is the Grigna Settentrionale hike?
The hike is rated EE (Experienced Hikers). It is physically demanding — 1,495m of elevation gain from Esino Lario — and includes exposed, rocky sections near the summit with some aided passages (chains). Good mountain fitness, proper ankle-support hiking boots, and prior experience with steep alpine terrain are required. Do not attempt this route if you are not accustomed to long mountain days or have not hiked at altitude before. It is not suitable for casual walkers, young children, or anyone without appropriate footwear. Plan for a full day.
ENHow long does it take to climb Grigna from Esino Lario?
From Esino Lario (914m) to the summit (2,409m): approximately 4 hours of ascent for a fit, experienced hiker. Add 30–45 minutes for the stop at Rifugio Bogani. The descent takes about 2h45'. Total day: 7.5–8.5 hours including breaks. Most hikers leave Esino between 7:00 and 8:00 AM to reach the summit before early afternoon thunderstorms, which are common in summer on the Prealps.
ENIs there a mountain hut on the way to Grigna Settentrionale?
Yes. The Rifugio Monza-Bogani (1,816m) is located on the main route from Esino Lario, about 2h30' from the village. It has 50 beds, a full kitchen serving alpine cuisine, and is managed by CAI Monza. Open from June to October. Booking is required in July and August for overnight stays. Phone: 368 253 7021. Even if you are not sleeping there, a meal stop is highly recommended before tackling the final ridge.
ENCan you do the Grigna Settentrionale as a day trip from Milan?
Yes, but it is a long and demanding day. The typical itinerary: train from Milano Centrale to Varenna-Esino (~1h20'), bus SP62 to Esino (~30 min), ascent to the summit (~4h), descent (~2h45'), bus and train back. Total: 10–12 hours including transfers. It is essential to take the first available train from Milan (around 6:30–7:00 AM) to be on the summit before early afternoon and descend before sunset. Do not attempt this itinerary unless you are in good physical shape.
ENWhen is the best time to hike the Grigna Settentrionale?
The optimal window is June to October. September is considered by many the best month: more stable weather, exceptional visibility, fewer crowds compared to the summer peak. July and August are the busiest months, with higher risk of afternoon thunderstorms. In May and early June snow may still be present above 2000m — check conditions beforehand. In winter the Grigna is a genuine alpine route requiring ice axe, crampons, and experience on snow and ice.
ENWhat equipment do I need for the Grigna Settentrionale?
Essential equipment: ankle-support hiking boots with grippy soles (no trainers), rain jacket and fleece layer (even in summer), at least 2 litres of water per person, food for a full day, trekking poles (especially important for the descent), sun protection SPF 50+, hat and gloves (can be cold near the summit even in summer), headtorch with checked batteries, first-aid kit, CAI topographic map sheet 12. Recommendation: leave Esino no later than 8:00 AM to be on the summit before early afternoon.
ENCan you bring a dog on the Grigna Settentrionale?
Technically it is not prohibited, but it is strongly discouraged for the final ridge. The aided sections with fixed chains require balance and agility that most dogs cannot safely manage. Wet limestone is slippery even for clawed paws. If you want to bring your dog, limit the hike to Rifugio Bogani (1816m): the trail to the hut is manageable for fit, medium-to-large dogs.
