Plenty of people find Lake Orta by accident. They're on their way to Lake Maggiore, or they spot it on a map of northern Italy and wonder about the little blue strip tucked into the hills. Then they see San Giulio Island sitting in the middle of the water and decide to stay a bit longer.
This guide brings everything together: where the lake is, what each town is like, what to do, when to come, how to get here and where to stay. Wherever we've written about a topic in more depth, you'll find a link to that article.
Lake Orta at a glance: where it is and why it's different
Lake Orta sits in Piedmont, in north-west Italy, just west of Lake Maggiore and separated from it by the Mottarone mountain. Italians also call it Cusio, after the old name for the area. From central Milan it's usually around an hour and a quarter by car, depending on traffic.
It's a small lake, roughly 13 km long and never much more than 2 km wide, so from almost anywhere on the shore you can see across to the other side. It's also surprisingly deep for its size.
How deep is Lake Orta?
At its deepest point Lake Orta reaches about 143 metres. Because it's so narrow, the water gets deep quickly in many places. On calm days that's what gives it its dark green-blue colour.
Key facts
- Region: Piedmont, split between the provinces of Novara and Verbano-Cusio-Ossola
- Length: about 13 km
- Maximum depth: about 143 m
- Main town for visitors: Orta San Giulio
- Island: Isola San Giulio, with its Romanesque basilica and Benedictine abbey
- A curiosity: it's one of the few Alpine lakes that drains northwards, through the Nigoglia stream at Omegna
Why it feels different from Como and Garda
Lake Orta has no grand ferry network, no long rows of big hotels and no traffic jams along the shore road. The villages are small and the evenings are quiet. It has its share of day-trippers in high summer, but compared with the big lakes it still feels like a place where people live, not only a place they visit.
The lake also has an interesting environmental story. It was badly polluted by industry in the twentieth century and was brought back to life by a large-scale liming project. We tell that story in The Miracle of Liming. If you're weighing it up against the bigger lakes, read our comparisons with Lake Como, Lake Garda and Lake Maggiore.
Lake Orta map: towns, island, viewpoints and ferry stops
The interactive map below shows the whole lake. Zoom in to see the villages along the shore and the roads that link them.
Here's what you'll find around the shore, place by place:
- Orta San Giulio – on the east shore, on a small peninsula. This is the historic heart of the lake, with the lakeside square, the boats to the island and the Sacro Monte on the hill behind.
- Isola San Giulio – the island just off Orta, a few minutes away by boat. It has a basilica, an abbey and a single lane that loops around it.
- Pella – on the west shore, directly opposite Orta. It's a small village with a pretty waterfront, and it looks straight across to the island.
- Madonna del Sasso – a sanctuary on a rocky outcrop high above the west shore. It's one of the best viewpoints over the whole lake.
- Omegna – the largest town, at the northern tip. It has shops, a weekly market and a lively lakefront, and it's where the lake drains out through the Nigoglia.
- Pettenasco – a quiet village on the east shore, north of Orta, with easy access to the water.
- Gozzano – at the southern end of the lake, with a basilica on the hill and views up the length of the lake.
- Ameno – a peaceful hill village above Orta, surrounded by woods and old villas.
Ferries and boats
Public boats run by Navigazione Lago d'Orta link Orta San Giulio, the island, Pella and several other villages. Services are more frequent in summer and limited in the off-season. Timetables change from season to season, so check the current schedule on the Navigazione Lago d'Orta website or at the landing stages before you plan your day. From Piazza Motta in Orta, small private boats also make the short crossing to the island throughout the day in season.
Orta San Giulio and San Giulio Island
Most visitors base themselves in Orta San Giulio, and it's easy to see why. Cars aren't allowed in the historic centre, so you explore on foot along narrow cobbled lanes lined with old houses, small shops and glimpses of the lake.
Everything leads to Piazza Motta, the square that opens directly onto the water. It's framed by the arcaded Palazzo della Comunità, with San Giulio Island right in front of you. Have a coffee here in the morning before the day-trippers arrive and you'll understand why people come back year after year.
San Giulio Island and the Way of Silence
The island is small enough to walk around in about a quarter of an hour, but don't rush it. A single lane circles the island past the Basilica of San Giulio and the walls of a Benedictine abbey that's still active. Along the lane, small signs in several languages invite you to reflect, which is why it's known as the Way of Silence and the Way of Meditation. Please keep your voice down: people live here.
The island has plenty of stories. Read about the saint who, according to tradition, freed it of serpents in The Legend of San Giulio, and about the children's novel set here in Baron Lamberto and San Giulio Island.
Sacro Monte di Orta
Above the village, a wooded hill holds the Sacro Monte di Orta. A path links twenty chapels dedicated to the life of St Francis of Assisi, filled with frescoes and life-size terracotta figures. It's part of the Sacri Monti of Piedmont and Lombardy, a UNESCO World Heritage Site, and it's a beautiful place for a shady walk with views down to the island. Our Sacro Monte di Orta guide covers it in detail.
Best things to do on Lake Orta
Lake Orta is about doing a few things well and slowly. Here's a quick overview, with links to our detailed guides:
- Swim in the lake. The water is clean and swimming is a real highlight in summer. See Swimming in Lake Orta and our guide to the best beaches on Lake Orta.
- Walk the lake. Old mule tracks and footpaths link the villages, so you can walk short stretches or tackle the whole loop over several days. See Walking around Lake Orta.
- Get out on the water. The lake gets steady afternoon breezes, which makes it good for sailing. Read sailing on Lake Orta and wakeboarding and wakesurfing.
- Eat well. There are simple trattorias and lakeside terraces, as well as Villa Crespi, the Michelin-starred restaurant set in an extraordinary Moorish-style villa. Start with our guide to where to eat on Lake Orta.
- Take a cold plunge. For something wilder, try our favourite waterfall near Lake Orta.
- Explore more of the outdoors. You can also cycle, kayak, paddleboard and hike in the hills. See Outdoor activities on Lake Orta.

When to go: Lake Orta weather month by month
Lake Orta has something to offer all year round. The lake softens the climate a little, but it's still at the foot of the Alps, so winters are properly cold and summers are warm rather than scorching. Here's a rough guide to what to expect.
- December–February: cold, often crisp and clear, with occasional frost and the odd snowfall on the surrounding hills. Very quiet, apart from the festive season. Some restaurants and shops close or open shorter hours.
- March–April: mild days, cool evenings and changeable weather. Camellias, magnolias and fresh green woods. Few visitors, except around Easter.
- May–June: warm, green and lush, and one of the loveliest times to come. In June the water starts to feel inviting. Busier at weekends.
- July–August: the warmest months and the best for swimming, with the water often in the low-to-mid twenties °C. Thunderstorms can roll in during the afternoon. This is the busiest period, especially at weekends and around mid-August.
- September: still warm, and the lake holds its summer heat, so swimming is often possible early in the month. The crowds thin out.
- October–November: autumn colours on the hills, misty mornings and some rainy spells. Quiet, unhurried and very atmospheric.
Which season suits you?
Summer is for swimming, boats and long evenings outdoors. Late spring and early autumn are ideal for walking and for having the villages mostly to yourself. Read more in Lake Orta in spring and the shoulder season and Lake Orta in autumn and winter.
Winter is the quietest time of all. The festive season brings lights and seasonal events. See Christmas and New Year on Lake Orta. For the warmer months, check our roundup of spring and summer events.
How to get to Lake Orta (from Milan, Malpensa and beyond)
Lake Orta feels remote once you're here, but it's surprisingly easy to reach. Here's a summary. Our full guide, How to get to Lake Orta, has all the details.
By car
This is the simplest option, and it lets you explore the whole lake and the surrounding valleys. From Milan, take the motorway towards Lake Maggiore and Gravellona Toce, leaving it for Lake Orta. The drive usually takes around an hour and a quarter. Orta San Giulio's historic centre is closed to traffic, so you'll park in the car parks just outside it.
Milan to Lake Orta by train
The nearest station to Orta San Giulio is Orta-Miasino, on the line between Novara and Domodossola. From Milan you'll normally change trains at Novara. From Orta-Miasino it's a downhill walk of about 20 minutes into the village. Local trains on this line aren't very frequent, so check times on the official Trenitalia website before you travel.
From Malpensa Airport
Milan Malpensa is the closest major airport, usually less than an hour's drive away. Renting a car or booking a transfer is the easiest way to get here. Getting here by public transport is possible, but it means at least one change and takes longer.
Where to stay: weekend, summer holiday or a month on the lake
The right place to stay depends on how long you're coming for and how you like to travel.
Hotels or a holiday home?
For a night or two, a hotel in or near Orta San Giulio works well. For anything longer, many visitors prefer a holiday villa or apartment. You get space to spread out, a kitchen for market produce and local wine, and the feeling of living on the lake rather than just passing through. That counts for a lot on Lake Orta, where the evenings are quiet and the best moments often happen at home: a swim before breakfast, or dinner as the light fades over the island.
Travelling with a dog
Lake Orta is a good destination for dogs, with lakeside paths, woodland trails and plenty of shade. Not all accommodation accepts pets, so check before you book. Our dog-friendly guide to Lake Orta has practical tips.
A month or more on the lake
From October to May, when the lake is at its quietest, a longer stay makes a lot of sense. Remote workers, writers, retirees and travellers from further afield, including many from the US, choose to spend a month or more here. They settle into a routine with mornings at work, afternoon walks and weekends exploring Piedmont and the other lakes. Our guide to a mid-term stay on Lake Orta explains how it works.
Staying at Villa Volpe
Villa Volpe is right on the lakefront in Orta San Giulio, an easy walk from Piazza Motta and the boats to the island. It sleeps four people, so it suits a couple, a family or two friends. Dogs are welcome, and the house has its own private beach, so you can swim straight from the garden. It's also wheelchair accessible, which is still rare on a lake full of steps and cobbles. Outside the summer season, from October to May, we offer monthly rates for longer stays.
If you'd like to experience Lake Orta the way locals do, with the water at your doorstep and the village around the corner, you can check availability and book direct. For practical questions about the house, see our FAQs.
Questions people ask
Can you swim in Lake Orta?
Yes. Lake Orta's water is clean, and swimming is one of the highlights of a summer visit. The water is usually warmest from July to early September, and there are several beaches and lidos around the shore.
Is Lake Orta worth visiting compared with Lake Como?
If you're after peace, authentic villages and fewer crowds, very much so. Lake Orta is smaller and quieter than Lake Como, with a single historic centre and an island that feel very intimate. Many people combine the two, or choose Orta as a calmer base.
How many days do you need on Lake Orta?
You can see Orta San Giulio and the island in a day, but two or three days let you swim, walk, visit the Sacro Monte and explore the other villages. A week or longer gives you time to slow down and take day trips to Lake Maggiore and the mountains.
Is Lake Orta busy?
Summer weekends and mid-August bring day-trippers to Orta San Giulio and the island, especially around midday. Early mornings, evenings and weekdays are much calmer, and from October to May the lake is very quiet.
Can you visit Lake Orta in winter?
Yes. Winter is cold but often clear, and the villages are peaceful and atmospheric. Some restaurants and boat services reduce their hours, so check ahead, but walking, the views and the festive season make it a lovely time for a quiet stay.
