Nature Reserve Arkutino (Bear Swamp) | Primorsko

Arkutino Nature Reserve – Detailed Overview

Arkutino (Аркутино), also known as the "Bear Swamp" (Мечешкото блато), is a protected nature reserve located along Bulgaria’s southern Black Sea coast, between the towns of Primorsko and Sozopol. It forms part of the larger Ropotamo Nature Reserve and is one of the most ecologically diverse wetland systems in Bulgaria. The reserve covers a combination of freshwater marshes, sand dunes, lagoons, and forest ecosystems, all set against the backdrop of the Black Sea coast and the Strandzha Mountains.

Geographical Location and Terrain

Location: Arkutino is situated about 2.5 km northwest of the mouth of the Ropotamo River and 7 km south of Sozopol. It lies in the southeastern part of Bulgaria, near the coastal road between Sozopol and Primorsko.

Landscape: The reserve is nestled between sand dunes and coastal cliffs. A narrow strip of dunes separates the sea from a shallow freshwater swamp and marshland. These unique environmental layers create multiple microhabitats in a small area.

Altitude: The area is low-lying, with the wetland and lagoon areas lying just meters above sea level.

Ecological Zones and Habitats

Arkutino is remarkable for its compact yet highly varied natural zones:

Freshwater Swamp and Lagoon:

This is the central feature of the reserve—a shallow freshwater body that forms a swamp-lagoon ecosystem, not directly connected to the sea.

The lagoon is bordered by reeds (Phragmites), bulrush (Typha), and other aquatic vegetation.

In summer, the surface of the lagoon is covered with beautiful white water lilies (Nymphaea alba), giving the area an almost magical appearance.

Sand Dunes:

Separating the lagoon from the sea, Arkutino’s sand dunes are among the largest on Bulgaria’s coast.

The dunes are covered by specific dune vegetation, including sand lilies (Pancratium maritimum), rare grasses, and herbs adapted to the dry, salty conditions.

These dunes are crucial for preventing sea intrusion and maintaining the freshwater balance of the lagoon.

Coastal Forest and Shrubland:

Around the swamp and dunes, patches of oak, hornbeam, and Mediterranean-type shrub vegetation grow.

The forest zone is important for bird nesting and shelter for mammals.

Rock Formations and Nearby Capes:

The reserve also includes small rocky outcrops and cliffs, such as Cape Kaya, offering panoramic views of the sea.

Fish:

The wetland is home to Gambusia holbrooki (mosquitofish), a species introduced for mosquito control.

Native fish also inhabit the lagoon, including carp species and minnows.

Mammals:

Small mammals such as otters, foxes, hedgehogs, and wild boar can be found in the surrounding forest.

Tourism and Visitor Experience

Birdwatching (especially during migration seasons in spring and autumn)

Botanical photography

Wildlife observation
