The dune was formed by the combined action of wind and water deposits over several centuries.
The site acts as a critical sediment trap, influencing the geomorphology of the Lielupe River mouth.
The dune is classified as a geological and geomorphological nature monument in Latvia.
Its current structure is subject to ongoing erosion due to sea level fluctuations and storm surges.
The surrounding pine forest has been managed to prevent sand drift into the residential areas of Lielupe.
The Lielupe White Dune (Baltā kāpa) is a naturally formed sand formation located at the point where the Lielupe River flows into the Gulf of Riga. The dune rises to a height of approximately 15 meters, offering panoramic views of the coastline and the river estuary. It is a protected geological monument characterized by its steep, wind-eroded slopes and dense pine forest surroundings. A wooden boardwalk trail provides elevated access to the viewpoint while preserving the fragile sand structure. The site serves as an important nesting habitat for various coastal bird species. The confluence point creates a unique dynamic between the freshwater river current and the brackish sea water. The area is part of the larger Jūrmala coastal landscape and is integrated into the city’s network of nature trails.
The highest wooden viewing platform looking north toward the Gulf of Riga.
Walk the full length of the wooden boardwalk to see both the river confluence and the open sea.
Bring binoculars as the river mouth is a prime location for observing migrating waterfowl.
Wear closed-toe shoes as sand is deep and uneven off the boardwalk sections.
Attempting to climb the steep, unprotected face of the dune, as this accelerates erosion and is prohibited.
Stay on marked boardwalks to prevent damage to the dune's fragile vegetation and soil structure.
