The delta is part of the broader Nestos-Vistonida-Ismarida National Park, covering approximately 55,000 hectares.
The riparian forest of Kotza Orman is one of the few remaining lowland forests in Greece, featuring old-growth trees and dense vegetation.
The area hosts over 250 species of birds throughout the year, with numbers peaking during spring and autumn migration cycles.
The Nestos River deposits significant sediment, causing the delta's coastline to continuously shift and expand into the sea.
The salt marshes and lagoons support a unique saline-tolerant flora adapted to high mineral concentrations.
The region is a primary breeding ground for the endangered Dalmatian Pelican.
The delta contains a rare microclimate that supports both Mediterranean and Central European plant species.
The Nestos Delta National Park is a protected wetland ecosystem where the Nestos River flows into the Thracian Sea, forming a complex landscape of lagoons, sand dunes, and salt marshes. The park is a critical stopover and nesting site for migratory bird species, including flamingos, pelicans, and raptors. The terrain consists of diverse habitats such as the riparian forests of Kotza Orman, freshwater lakes, and coastal lagoons. Visitors can observe wildlife through a network of trails and observation points situated across the delta's shifting channels. This area is officially designated as a Ramsar site of international importance due to its biodiversity. The delta’s hydrology is characterized by seasonal fluctuations that directly influence the movement of waterfowl and the density of aquatic vegetation. It serves as one of the few remaining large deltaic systems in Greece that maintains significant natural ecological processes.
The raised wooden observation decks located near the Enetiko lagoon provide panoramic views of the water and nesting flocks.
Carry high-quality binoculars or a spotting scope, as wildlife is often found at a distance from walking paths.
Apply high-protection insect repellent, as the marshy environment supports a high density of mosquitoes.
Stick to established trails to avoid disturbing ground-nesting birds or damaging sensitive dune vegetation.
Attempting to traverse off-trail areas in the wetlands, as the soft, muddy substrate can be hazardous and ecologically destructive.
Maintain silence to avoid startling wildlife; do not use flash photography; pack out all trash to protect the ecosystem.
