06 – Alpes-Maritimes

The Alpes-Maritimes combines Mediterranean coastline, limestone gorges and high alpine terrain within a compact area. This exceptional altitudinal range supports one of the richest biodiversities in France, with Mediterranean reptiles, alpine mammals, diverse birdlife and a highly varied flora concentrated across a relatively small geographic area.

Wild Places

These are listed by order of importance, National, Regional Parks, Reserves and local hotspots that should be of interest to all nature lovers, whether serious listers or casual observers.

Waiting To Be Discovered Are:

mercantour national park

Mercantour National Park

Flora:  Over 2 000 plant species, with 200 rare & 30 endemic. Fauna:  78 species of mammals including 6 wild ungulates, a prey source for the park’s apex predator, the grey wolf.  Plus 199 bird species.

Pre-Alps Regional Park

Located in Alpes-Maritimes, the Préalpes d’Azur Regional Natural Park ranges in altitude from 300 to 1,800 metres, between the Valleys of Le Loup, Le Cagne, L’Estéron, La Siagne and Le Var.

RNR – Gorges de Dalius

A geologically remarkable, biologically rich protected area where Mediterranean and alpine worlds meet. Its flora comprises drought-tolerant Mediterranean shrubs and specialised rock plants on nutrient-poor soils, while its fauna includes alpine mammals, rare reptiles, diverse birds of prey and endemic invertebrates. This diversity stems from its spectacular canyon landscape, altitudinal range and transitional position between biogeographical

Fort de la Revère

Visual Migration: A premier natural observation point overlooking the Mediterranean, renowned for its dramatic autumn bird migration. Positioned on a major migratory flyway, the site channels tens of thousands of birds through a narrow coastal corridor, creating a spectacular and visible passage each year. Combining panoramic scenery, historic heritage, and active ornithological monitoring, it is one of the most important migration viewpoints in the Provence-Alpes-Côte d’Azur region.

Vaugrenier Park

Located at Villeneuve-Loubet, within one of the most heavily urbanised stretches of the Alpes-Maritimes coastline. The park centres on a series of permanent water bodies, reed-fringed margins, wooded parkland and open grassy areas, creating a structurally diverse but highly controlled environment. Despite its recreational role, the site functions as a key lowland refuge for wetland and generalist bird species, providing year-round value for wildlife observation and biological recording and hotspot for migrating Crake species.

Pelagos

Additional Wildlife Hotspots

These sites fall outside formal protected area boundaries but are widely recognised for their ecological significance.

Dynamic river-mouth system with gravel banks, lagoons, shoreline and adjacent coastal waters.

Why this site matters:
The most important lowland ecological system in the department outside formal protection. Functions as a migration bottleneck for passerines, a wintering area for divers, grebes and ducks, and a key coastal seawatching point.

Species of interest:
Common Tern (breeding) · wintering grebes and divers · passage passerines

Seawatching & Migration Funnel

Open coastal frontage adjacent to the Var estuary, with clear views of nearshore and offshore movement.

Why this site matters:
Acts as a key seawatching point and coastal migration funnel. Migratory passerines are concentrated along the shoreline, while winter storms and onshore winds bring seabirds close to land.

Species of interest:
Divers · grebes · auks · offshore shearwaters

Sheltered bays, estuaries and nearshore waters along the urbanised Riviera coastline.

Why this site matters:
Despite heavy development, these waters remain important for wintering and passage seabirds. Bays provide shelter during adverse weather, concentrating species otherwise dispersed offshore.

Species of interest:
Divers · grebes · auks · offshore shearwaters

Notable records:
Occasional extreme vagrants have occurred along this stretch, including a Brown Booby observed offshore and lingering locally in recent years.

Best conditions:
Strong onshore winds, winter storms and post-frontal systems significantly increase diversity and detectability.

Mixed agricultural land with hedgerows, small water features and scrub.

Why this site matters:
One of the last lowland agricultural mosaics on the Côte d’Azur, important for small birds during migration.

Species of interest:
Passage passerines

Open slopes and heathland on acidic substrates outside protected cores.

Why this site matters:
Floristically and structurally distinct from the limestone-dominated landscapes elsewhere in the department.

Species of interest:
Heathland-associated birds · pollinators

Field Calendar and Seasonal Dynamics

Spring (March to May) and Autumn (September to October) provide excellent trans-border passage dynamics, tracking raptor movement along the alpine ridges and active migrant landfalls along the immediate Mediterranean coastline. Naturalists navigating the transition from coastal scrub to high sub-alpine territory should utilise the comprehensive, free digital guidebooks and mapping sectors on the RandOxygène portal before embarking.

Winter (November to February) delivers a dramatic dual profile, locking the high-altitude Mercantour backcountry under heavy snow while leaving the sheltered coastal river mouths and mid-country conifer belts wide open for sub-alpine specialists and pelagic seabirds. 

Summer Forest Access and Fire Risk Regulations (DFCI)

During the summer season, the sub-alpine massifs, steep river valleys and coastal formations of the Alpes-Maritimes are placed under strict prefectural fire prevention mandates. The primary ecological risk vector stems from the sharp topographical transition from maritime coastlines to high altitudes, where dense maritime pine forests and volatile, aromatic scrub communities intersect with frequent dry summer lightning storms.

Access permissions are evaluated across distinct geographic sectors (such as the Estérel-Tanneron fringe or the high backcountry) and are updated each evening for the following day.
Green or Yellow codes allow full access.
Orange codes allow access but users should exercise extreme caution as professional brush-cutting and metalworking machinery face tight hourly restrictions.
Red codes completely prohibit all access all day for all recreational activities, including hiking, canyoning and mountain biking.

Naturalists should consult the daily zoning directives nightly via the Alpes-Maritimes Prefecture Risk Portal. Note that fire risk designations for the western edge of the department automatically align with the regulations of the neighbouring Var department due to the ecological continuity of the Estérel massif.
