About Sandwich Harbour

Sandwich Harbour is a coastal lagoon and dune system on Namibia’s Atlantic coast, notable for where high mobile sand dunes meet the sea. It is one of the region’s distinctive dune-sea landscapes and is located on the Namibian shoreline south of Walvis Bay.

The site is valued for dramatic dune-swept beaches and a narrow lagoon running behind the dunes, offering close views of the point where desert meets ocean. Birdwatching is a major draw, with waders and flamingos often concentrated in the sheltered parts of the lagoon. Guided 4x4 excursions and boat trips from nearby towns give access to viewpoints where dunes sweep down to the water.

The area has been shaped by ongoing coastal and aeolian processes rather than by human construction; its current form reflects shifting dunes and tidal influence. There is a history of restricted access to protect sensitive habitats and cultural remains along the coast.

Sandwich Harbour lies on Namibia’s central Atlantic coast, roughly south of Walvis Bay and within the coastal strip of the Namib Desert. The nearest service towns for visitors are Walvis Bay and Swakopmund, which provide tours and transport to the site.

  • Access: Best visited on guided 4x4 or boat tours from Walvis Bay; vehicle access along the coast is difficult and restricted in places to protect habitat.
  • Birdlife: Important for waterbirds including waders and flamingos, with large congregations visible in sheltered parts of the lagoon during suitable seasons.

What to See#

  • Lagoon and mudflats: A coastal lagoon and mudflat area formed where large mobile sand dunes meet the Atlantic Ocean, creating a narrow lagoon separated from the open sea by dune ridges.
  • Coastal sand dunes: The strip of high coastal dunes directly behind the shoreline where sand repeatedly shifts toward the sea and meets the marine edge, producing the distinctive dune-sea interface.
