The sandstone Christuskirche is, despite its modest size and unimposing appearance, somewhat of the city's symbol. Designed by a prolific German architect, the church marks an important era in Namibian history, and remains an attractive location for locals to exchange vows in marriage.

The seaside promenade is a lovely hiking trail along the coast in central Karlshamn. It is about 2 kilometres long and starts at the statue of the emigrants, Karl Oskar and Kristina, in Näsviken. The hiking trail goes all the way out to Vägga fishing harbour, where you'll find a smokehouse, fish restaurant, café, and campsite. Along the trail, there are several public barbecue spots and places with great views to enjoy. Along the way, you'll also pass by Cafe Villa Utsikten (only open in the summer, but a very nice viewpoint all year round), paddle courts, Väggabadet (swimming pools) and Karlshamn’s Kallbadhus (outdoor swimming bath).

Historic Ships in Baltimore, a National Historic Landmark, features five historic maritime artifacts: the USS Constellation, the last Civil War-era warship afloat; the USS Torsk, a Cold War submarine; the USCGC Taney, which survived the attack on Pearl Harbor; the Lightship 116 Chesapeake; and the Seven Foot Knoll Lighthouse, one of Baltimore’s oldest lighthouses. Visitors can explore these ships through guided tours, interactive exhibits, and even overnight adventures.

The Baltimore Water Taxi is a fun and convenient way to explore the city's waterfront. It offers easy access to popular attractions like the Inner Harbor, Fells Point, and more, with stops at various key destinations. While water taxis generally run frequently throughout the day, it's important to note that schedules can vary depending on the time of year, weather, and demand. If you're planning a specific itinerary or visiting during peak times, it's a good idea to check the schedule ahead of time to make sure you don’t miss a ride.
