Étang de Biguglia Nature Reserve

At Biguglia, the interesting boundary is between fresh water and salt water.

About

At Biguglia, the interesting boundary is between fresh water and salt water. Rivers and drainage channels meet seawater entering through the lagoon’s mouth, creating a shallow, productive wetland south of Bastia. The wider reserve covers 1,790 hectares across Furiani, Biguglia, Borgo and Lucciana; a short walk explores only one small edge of it.

The landscape changes in bands: open water, muddy margins, reeds, salt-tolerant vegetation and trees, then the Marana coastal strip and the sea. Looking across those bands is more rewarding than trying to reach every shore. Some of the busiest-looking patches of water may be far beyond a phone camera’s useful reach, so binoculars make a real difference.

Make Tombulu biancu, on the Furiani side of the Marana strip, your first choice for an independent nature walk. The manager’s current circulation map identifies it as permanently open to pedestrians. Parc de Fornacina is another public discovery setting, explicitly recommended by the manager while the Écomusée du Fortin is closed. The museum’s closure is for safety reasons; neither its exhibition nor its terrace should be part of your promised day.

The reserve is also a working landscape with a long fishing history. Professional lagoon fishing is managed separately from visitor recreation. Seeing fishing installations is a chance to think about the relationship between water quality, fish and birds, rather than an invitation to fish or enter the water. Turn your visit into a safari! Use the Snappit app to scan and log wildlife sightings here.

The lagoon is also known locally as Chjurlinu or Chiurlinu. Its importance for waterbirds led to international Ramsar recognition in 1991, followed by nature-reserve classification in 1994. The Genoese-era Fortin on the islet of Ischia Nova became an ecomuseum in 2011, interpreting the lagoon and its fishing traditions. Its current closure leaves the outdoor landscape as the focus of a visit.

What to do here

Choose one authorised shore path, find a comfortable place to watch, and give the water time to reveal its inhabitants. At Tombulu biancu, alternate a broad scan of the lagoon with a closer look at the vegetation beside the path. Keep the outing flexible: a short return along the same open path is a perfectly good visit, especially with children. Use the official circulation map to check the route name and access category before setting off.

Seasonal info

Access changes by named sector. Tombulu biancu is classified as permanently open; Bevinco Sud is seasonal, from 15 September to 15 March; Sentier du Bevinco and Boucle Presqu’île are seasonal guided-access sectors. A date within the seasonal window does not override a temporary closure or make a guided-only path independent access.

Accessibility

The low-lying setting does not establish a step-free route. For Tombulu biancu, ask the reserve about the current entrance, surface, barriers and any suitable turning point before bringing a wheelchair or pushchair. Fornacina may offer a different outing, but it is not a verified accessible substitute. Do not rely on the closed Fortin for toilets, shelter or accessible facilities.

Walks and routes

Tombulu biancu: the first-visit shore walk

Head for the Tombulu Biancu / central Marana beach area in Furiani, then find the signed reserve discovery-path entrance on the lagoon side. Match it to Tombulu biancu on the official map, where it is marked permanently open. Follow that authorised path, stop wherever the view is clear without stepping off it, and turn back when you have had enough. Do not extend the walk across an unmarked shoreline link or treat the beach itself as the reserve trail. Allow 1–2 hours including stops.

Check the entrance-to-path connection and surface with the reserve before relying on a wheelchair or pushchair route. Keep a short return option and supervise children around the lagoon edge and the coastal road.

Tombulu biancu: the first-visit shore walk

An easy first outing

Arrive with drinks and binoculars ready. Check the entrance signs, walk a comfortable stretch of Tombulu biancu, and spend at least one stop looking across open water before returning the same way. Finish while everyone still has energy; an optional beach stop can be a separate part of the day.

For a more detailed visit

Arrange a reserve-led outing if you want help understanding bird movements, lagoon management or a guided-only sector. Ask which route is actually included and how long the activity lasts. The names Sentier du Bevinco and Boucle Presqu’île on the map do not constitute permission to explore them alone.

Things to try

Compare two shores

After the lagoon walk, a separate stop at the public beach can make the geography click: the same narrow coastal strip faces enclosed lagoon water on one side and the Mediterranean on the other. Use signed accesses and a safe crossing rather than cutting across vegetation. Decide about any sea bathing separately after checking beach conditions.

A small birdwatching challenge

Instead of chasing a species list, choose three birds you can see well and compare how they use the water. Which spends time diving? Which stays near cover? Which rests without feeding? A notebook or a distant photograph is enough; let uncertain identifications remain uncertain.

When the weather turns

Do not use the Fortin as a wet-weather fallback while it remains closed. If there is thunder, strong wind or water over the path, postpone the exposed lagoon walk. For light rain, only continue if the permitted route is comfortable and clear; turning back early is better than searching for a dry shortcut through protected ground.

Wildlife and habitats

Eurasian coot

A useful bird to learn first: the dark body contrasts with a white bill and forehead shield. Biguglia’s importance for coots is part of its wetland story. Watch from the path and compare their shape with the ducks nearby.

Tufted duck

An adult male’s dark upperparts, white sides and small crest are good starting clues. Use the binocular view to check the whole bird rather than naming every black-and-white shape. This diving duck is among the waterbirds associated with the lagoon.

Common pochard

In winter and spring, look for a male with a reddish-brown head, dark breast and grey body. Females are subtler, so take your time. The reserve supports this species, although a distant group may be impossible to identify confidently.

Greater flamingo

A recorded member of the reserve’s birdlife, best treated as a possible bonus. If distant flamingos are present, enjoy the group through optics rather than trying to reach their patch of water. Their inclusion here is not a forecast for your visit.

European pond turtle

This native freshwater turtle belongs to the reserve’s wildlife, including its channel habitats. A public-path glimpse is a bonus, not a reason to inspect drainage banks. Never handle a turtle or enter restricted ground to get a closer photograph.

Common reed

Reeds are part of the wetland’s architecture, creating cover beside open water. Look at the reedbed as a habitat in its own right, and listen without pushing through the stems. The plant is recorded in the reserve, but not every tall grass is this species.

Stories and discoveries

A lagoon with an exchange problem to solve

Freshwater inflow and seawater entering through the grau help shape this habitat. The manager monitors water quality as well as wildlife: conserving a wetland means looking after the water system, not only the visible birds.

More than reeds

The wetland includes salt meadows, tamarisk and alder stands, channels and aquatic plant beds. From the path, look for changes in height and texture rather than expecting one uniform belt of vegetation around the water.

When to visit

Autumn and winter

Build the visit around waterbirds and comfortable observation stops. Bring a layer that blocks the wind, and shorten the walk if conditions make binocular viewing tiring. Bevinco Sud’s mapped seasonal window is 15 September–15 March, but it is a separate route choice, not an automatic extension of Tombulu biancu.

Spring and summer

Spring is a good season for migration interest. In warmer weather, choose a shorter outing outside the hottest part of the day and take insect protection if you need it. Give nesting and resting birds plenty of space; neither a concealed nest nor an unusual call is a reason to leave the path.

Getting there and practical advice

Parc de Fornacina and the Fortin

The manager currently points visitors towards Parc de Fornacina while the Fortin is closed. Treat a park visit as its own outing and follow the signs in place. Older descriptions of a Fortin-based loop should not be used to bypass the current reserve circulation plan.

What to bring and arrange

Carry your own drinking water and a snack, and use toilets before arriving. Confirm any essential facilities with the reserve rather than assuming that museum services remain available during closure. For guided visits, check booking arrangements and prices directly; old museum tariffs are not a reliable budget.

Arriving at Tombulu Biancu

From Bastia, use the coastal-road approach along the Marana lido to the Tombulu Biancu beach area. The tourist office lists public parking there. Park in the designated area, then locate the signed lagoon-side discovery path; do not park on the verge simply because it gives a closer water view.

Without a car

Ask Bastia’s tourist office or ViaBastia for a service that reaches Tombulu Biancu on your exact date, including the return journey. Beach shuttles are seasonal, and an old summer timetable is not proof of present service. A station or stop bearing the name Furiani is not automatically the path entrance.

Choose a workable length before setting off

For limited stamina, plan a short out-and-back rather than depending on a loop. Ask about the nearest suitable drop-off, benches, surface firmness, path width and barriers. For sensory needs, consider wind, open exposure and the possibility of little shelter; the Fortin cannot currently be counted on as an indoor break.

Good to know before you go

Open the manager’s route map before travelling and check the signs at your chosen entrance.

Bring binoculars, drinking water, a hat and a windproof layer appropriate to the season.

Keep children beside you near water, channels and any road crossing.

Stay on the authorised path; a bare patch through reeds is not a visitor route.

Leave dogs at home

the reserve’s visitor rules prohibit them. Ask the manager in advance about assistance-dog arrangements.

Walk rather than cycle on reserve discovery paths, and leave drones, fishing equipment and collecting plans out of this visit.

Do not feed birds or play recorded calls. If animals move away in response to you, give them more space.

Take all litter away and plan food and toilet stops before arriving.

Frequently asked questions

Do not plan a complete waterside circuit. Public access is divided into specifically authorised paths, with permanent, seasonal and guided-only categories. Choose a named route on the official map and return by an authorised way.
The manager’s current map says it is closed for safety reasons, and Bastia’s tourist office also lists it as temporarily closed. No reopening date is given. Plan an outdoor visit and check with the reserve if the museum is important to your trip.
Keep this visit on the authorised land paths. Do not enter the lagoon or launch a craft as part of a self-guided nature visit. Nearby Mediterranean beaches are a separate destination, with their own conditions and rules.
Tombulu biancu is listed as a permanently open pedestrian path. For any guided activity, contact the reserve before travelling to confirm the meeting place, date, availability and any charge. The guided-only sectors are not available simply because you arrive with your own group.
Both greater flamingo and European pond turtle are recorded in the reserve, but neither is a guaranteed sighting from a particular public path. Enjoy whichever birds are visible and never leave the route to search canals, reeds or resting places.
