Many visitors to Zambia come for an African safari and usually head for game lodges or safari companies. Chief among the country's parks is South Luangwa National Park. Centred on the most intact major river system in Africa, it hosts a huge concentration of game, among the richest on the continent. Game concentrations are at their most intense during the dry season, from April to October, making this the best time to visit for a safari. The legendary 'Zambian walking safari' originated in this park and still offers one of the finest ways to experience the African wilderness close-up and personal. It is possible to visit the Zambian parks on a budget or to find luxury accommodation in lodges. However, even if visitors are travelling on a budget, it is worth splurging on some professionally guided game drives while in the national parks, as the rangers are often able to locate animals which are difficult to find when exploring independently.
