The elevation of Guinea-Bissau is largely flat, with its highest point reaching only 300 meters above sea level.
The central and southern regions of the country are generally flatter and more prone to flooding during the rainy season due to the many rivers that flow through the area.
The northern region of Guinea-Bissau, on the other hand, is more mountainous and home to a mix of low and high-altitude terrain.
The land is covered by a variety of forests, including mangroves in the coastal areas, savannas in the central and northern regions, and dense, tropical rainforests in the south.
