Avenida 4 de Fevereiro in Luanda is a prominent waterfront avenue and a key landmark of the city, offering scenic views of the Luanda Bay. It's generally accessible, but the availability of wheelchair ramps and other accessibility features can vary along its length. Exploring the avenue solo is possible, but a guided tour might enhance the experience with insights into the city's history and culture. Weather-wise, the dry season (May to September) is usually more comfortable for visiting. Costs depend on activities, dining, and transport, but expect Luanda to be relatively expensive compared to other African cities. A typical visit could last a few hours, depending on whether you're just strolling or stopping at cafes and attractions. Note that traffic can be heavy, especially during peak hours.
