Calandula Falls, located in the Malanje province of Angola, is one of Africa's largest waterfalls by volume. Accessibility can be challenging, often requiring a 4x4 vehicle due to the rough terrain, though improvements have been made recently. Solo visits are possible, but a guided tour is recommended for safety and local insights; guides can usually be hired in Calandula. There aren't significant seasonal restrictions, but the dry season (May to September) offers clearer views and easier access. Expect to spend around $50-$150 USD per person, including transport and guide fees. A typical visit lasts half a day to a full day, allowing time for viewing the falls from different angles and potentially visiting nearby areas.
