Avigliana Lakes Nature Park

The two lakes sit at the mouth of the Susa Valley, close to Turin, but offer different visits.

About

The two lakes sit at the mouth of the Susa Valley, close to Turin, but offer different visits. Lago Piccolo has the more natural shoreline; Lago Grande has more developed visitor edges. Water passes from the smaller lake into the larger one, then through the Mareschi wetland and the Canale della Naviglia. The surrounding hills give this compact waterside landscape its depth: you can move from reeds to woodland without planning a high-mountain hike. Don't forget to bring the Snappit nature identification app along to scan local species.

Protected since 1980, the park is also a landscape shaped by people. Beside the Mareschi marsh are remains of the Nobel explosives works, active from 1872 to 1965. Seeing industrial remains alongside recovering wetland adds another layer to the walk; it does not mean the factory buildings are open to explore.

What to do here

For a first visit, pick one of the signed habitat trails below and leave time to stop. The marsh suits patient wildlife watching, the Sentiero Collinare adds woodland and climbing, and Montecapretto gives a broader view of the landscape. Keep the lake circuit as a conditional option until its interrupted section is officially cleared.

Seasonal info

In warm weather, take water, sun protection and insect repellent. In winter, pack an extra layer for standing still beside the lake. Rain changes the usefulness of the paths more than their modest altitude suggests: wet shoes and a slow return can spoil an otherwise easy afternoon.

Accessibility

A short visit beside a parking or picnic area is a more adaptable option than committing to a circuit. Do not assume a lakeshore path is step-free: the interrupted Lago Piccolo route and its uphill diversion are particularly unsuitable as an unverified wheelchair or pushchair itinerary.

Walks and routes

Lago Piccolo: a shore-side visit, with an interruption

The blue-marked Sentiero lungolago follows Lago Piccolo's bank. Its published walking time is 1 hour 15 minutes, but that is a baseline for the listed itinerary, not today's usable circuit. For a lighter outing, spend time on an open section and return the same way. Coots, mallards and herons are among the birds described for this shore by the park's route guide.

For wheelchair or pushchair use, ask the park which shore-side sections currently have a firm, level approach and where to turn back.

Lago Piccolo: a shore-side visit, with an interruption

Sentiero Collinare: woodland above the small lake

This red-marked walking trail enters the wooded hills around Lago Piccolo. The operator gives 1 hour 45 minutes for the trail. Choose it when you want trees and changing terrain rather than an entirely waterside outing. Chestnut and oak woods support woodland birds and mammals, although seeing them is a matter of patience and chance. Read the official woodland-trail description.

The route involves climbing. Allow extra time for stops and don't treat the diversion as equivalent in effort or accessibility to the shore path.

Sentiero Collinare: woodland above the small lake

Sentiero della Palude: the Mareschi wetland

Follow the yellow-marked marsh trail for a closer look at the habitat beyond the lake. The published walking time is 1 hour 15 minutes. Reeds and sedges give it a different character from open water, while the remains of the Nobel factory provide an unexpected industrial backdrop. This is a good choice if you would rather linger than cover kilometres. Read the official marsh-trail description.

A wetland path can be soft or muddy. No verified all-weather wheelchair specification was found; ask about the particular stretch you intend to use.

Sentiero della Palude: the Mareschi wetland

Sentiero di Montecapretto: a short climb for the view

The ochre-marked trail climbs gently towards Montecapretto. The operator lists 30 minutes for the trail; allow additional time to reach it and return to your starting point. From above, the lakes, Mareschi and successive morainic hills become easier to read as one landscape. It is a useful alternative to another stretch of shoreline. Read the official Montecapretto description.

Short does not mean level. Choose footwear for an uphill woodland path and leave time to get back to your starting point.

Sentiero di Montecapretto: a short climb for the view

Anello dei Laghi: a longer plan to check first

The published Anello dei Laghi is 12 km with 100 m of stated elevation difference and about six hours' walking. Starting at Lago Piccolo's parking area, it combines the two lakes, the marsh and sections towards Borgata Sada, including roads and crossings outside the protected area. It is a broader town-and-landscape walk, not a continuous traffic-free lakeshore promenade. Consult the full official itinerary.

The road crossings and longer commitment make this a different proposition from a short nature stop. The published easy rating does not establish suitability for every mobility need.

An easy half-day

Choose the marsh trail if paths are firm enough, or an open shore-side section if you prefer a shorter visit. Keep the walking flexible, leave room for a picnic, and stop while you still have energy for the return. A good view and an unhurried look at the water are enough; the value of this visit isn't in completing a ring on a map.

A fuller day with a change of scene

Use the Sentiero Collinare or Montecapretto as the main walk, then make Avigliana's historic centre a separate stop. The town's squares and medieval buildings provide a change from reeds and woodland. Check the return transport before adding that second visit, especially on a Sunday or outside the shuttle season.

Things to try

Water activities: two lakes, different rules

The park's rules prohibit swimming and all boating on Lago Piccolo and in wildlife-protection zones; motorboats are prohibited on Lago Grande. If you want a paddle or swim on the larger lake, check the permitted area, local operator and current restrictions first. Fishing also requires the appropriate licences and is excluded from wildlife-protection zones and the Canale della Naviglia. A watersports advert does not override these rules.

Check water quality for the day you visit

Lago Grande had a cyanobacteria advisory in August 2026, followed by the municipality's report of suitable water for the 13 September swim event. Neither is a current all-clear. At this guide's 19 October check, ARPA said the 2026 bathing-monitoring season had ended on 30 September and would resume in May 2027. Consult the ARPA bathing portal and municipal notices when planning an in-water activity; don't use a historical bulletin as a present-day safety guarantee.

When the paths are too wet

Check Piemonte's official weather-alert information and the park's notices before leaving. If flooding, strong wind or poor footing makes the trails a bad choice, postpone the nature walk. Avigliana's town centre can be a separate alternative when conditions allow, but do not assume the Nobel remains or any monument provide an open indoor shelter.

Wildlife and habitats

What to watch for

Look across the open water for Great Crested Grebe, Mallard and Tufted Duck; autumn and winter can also bring Common Pochard. The waterside paths are places to look for Eurasian Coot and Grey Heron, while Common Moorhen uses the reed margins of Mareschi. Stay in one spot for a while: a still visitor is less disruptive than someone repeatedly approaching the water. Numbers and sightings vary, so leave yourself time to enjoy whatever appears.

Give breeding birds room

One of the seasonal highlights is grebes' courtship in late winter and early spring, with later chances to see chicks riding on a parent's back. Enjoy such behaviour from the path with binoculars. Avoid moving closer when a bird changes its behaviour, and never make reaching a nest part of the visit.

Stories and discoveries

A landscape left by ice

The hills are moraines, deposits left by glaciers, and the large erratic boulders are another trace of moving ice. The park describes a boulder-discovery path linking its woods with surrounding territory. If you'd like to follow that separate route, ask the park for its latest signed itinerary before setting out. Wetter woods west of Lago Piccolo contrast with the warmer, drier slopes north of Lago Grande.

When to visit

Spring brings amphibian movement

The woods and marsh are linked by amphibians' seasonal journeys to breeding water. In 2026 the municipality closed part of Via Grignetto at night from 16 February to 15 March to protect them. Those dates have passed; look for the next campaign's notices rather than assuming the same closure recurs unchanged. Join only currently advertised activities under their booking arrangements, and leave animals undisturbed during an ordinary walk.

Getting there and practical advice

Picnic areas, parking and toilets

The park's facilities list identifies picnic areas near its Via Monte Pirchiriano office and at the FIPS area below Borgata Sada on Lago Piccolo. It also lists an accessible toilet at the FIPS bar, and parking options by Lago Grande at Via Pontetto, Via Prole/Viale dei Mareschi and Piazzale Nino Costa. Treat these as places to enquire about, not guaranteed open services. Confirm toilets, access arrangements and any parking charges before relying on them; bring a cold picnic rather than assuming a barbecue is permitted.

Useful local contacts

The park office is at Via Monte Pirchiriano 54; telephone +39 011 9313000 for route and access enquiries. Avigliana's tourist information office is at Corso Laghi 389, telephone +39 011 9311873. Check their opening hours before making either office the essential first stop of your day.

Arriving by train and bus

Take a regional train to Avigliana; Trenitalia identifies the SFM3 connection from Turin and sells a combined journey to the destination 'Avigliana Laghi'. Check the actual journey date and return connection. Cavourese's 2026 seasonal Sacra di San Michele shuttle serves the lakes on Saturdays, Sundays and public holidays from 4 April to 31 October. That does not establish a daily, year-round lake shuttle. Use the operator's current line 253 timetables for the service that suits your day.

Tickets and the final stretch

The seasonal shuttle's 2026 timetable lists a €2.80 one-way onboard fare from Avigliana station to the lakes, including the surcharge, and cash-only onboard payment. Trenitalia's combined-ticket page separately lists a €1.80 bus component. Check the price for your chosen product instead of assuming those sales channels are interchangeable. Confirm your lake stop and the onward walk before boarding. If driving, the park brochure gives the A32 Avigliana Est exit as an approach; then choose a signed parking area near the part you want to visit.

Plan around your own access needs

Ask about the route from the chosen parking space or bus stop to the actual viewpoint, not just whether an area has an accessible toilet. A toilet listing does not establish opening, an unobstructed entrance or an accessible approach. For a lower-effort visit, consider one open viewing area with the option to return immediately; do not make the hill diversion a necessary part of the outing.

Good to know before you go

Bring binoculars and use the public paths; don't approach nests or push through the reeds for a photograph.

Wear footwear with grip and turn back before an unsafe flooded section. A signed diversion is not permission to improvise through private land.

Carry drinking water and a picnic if your day depends on them; seasonal cafés and toilets need a separate opening check.

Keep dogs on a lead, take litter away and leave plants and small animals where they are.

Frequently asked questions

Do not plan on a complete shoreline circuit until the park confirms reopening. The published interruption and hill-path alternative remain the relevant planning warning; current signs take precedence over an older map.
Lago Piccolo is protected from swimming and boating. On Lago Grande, use only permitted bathing areas when current municipal notices and ARPA advice allow it. A past summer's good result is not clearance for your visit.
Yes, if you build the outing around one manageable stretch and time beside the water. Keep children close at the bank and road crossings. Choose a turnaround point before setting off rather than promising a complete loop.
Organised activities have their own arrangements. Check the current park programme and reserve if the event requires it; an old event listing is not a standing offer. Independent walking, paid activities, parking and lakeside businesses should not be treated as one ticketed attraction.
