Sandwich Harbour Beach is generally not recommended for swimming due to the cold Atlantic waters, strong currents, and the presence of marine wildlife. Safety considerations primarily revolve around the tides; access to the beach can be cut off by high tide, trapping vehicles. Always visit with experienced guides who understand the tidal patterns and adhere to their instructions for safety.

The best time to visit Sandwich Harbour Beach is typically during the cooler, drier months from May to October. This period offers more comfortable temperatures for exploring the dunes and coastline. While popular year-round, visiting outside of major holiday periods can offer a slightly less crowded experience, allowing for more serene enjoyment of the iconic landscape.

Access to Sandwich Harbour Beach is strictly by 4x4 vehicle, and it's highly recommended to go with an experienced local guide or tour operator. The route involves driving on soft sand, navigating between towering dunes and the ocean, which requires significant off-road driving skills and knowledge of tidal movements. Independent access is often restricted and risky.

Sandwich Harbour Beach is located within the Namib-Naukluft National Park and is a protected, undeveloped area. There are no commercial food or lodging facilities directly at the beach. Visitors typically experience it as a day trip from Walvis Bay or Swakopmund, with tour operators often providing refreshments or a picnic lunch. Camping is not permitted directly on the beach.

Sandwich Harbour Beach is iconic for its dramatic landscape where towering desert dunes plunge directly into the Atlantic Ocean. This unique confluence of desert and sea creates breathtaking scenery, making it a world-renowned natural wonder. It's also a significant wetland area, attracting diverse birdlife, adding to its unique ecological and visual appeal.
