regulations and the scarcity of elephants in modern times have dampened this part of the economy. Much of the South's electricity is produced in hydroelectric power stations on the Ntem and Ma'an rivers. The South also has a fair amount of mineral wealth. Iron ore is mined near Campo and Kribi. Natural gas is found offshore of Campo, and a Kribi-based plant has been processing this since the 1980s. Perhaps the region's most lucrative resource is oil. This, too, is found off the coast of Campo. But more importantly, the South Province is located at the terminus of the Chad-Cameroon oil pipeline, which was completed in June 2004. The pipe's mouth is located just south of Kribi, a fact that promises to bring in high revenues for both Cameroon and the province. Transportation For a region so heavily forested, the South has a fairly developed transportation network. Four main roads service the greater area of the region. The first of these, National Road 2, runs from Yaoundé to Ambam and then to the border with Gabon and Equatorial Guinea. National Road 7 is located completely in the South, travelling along the coast from Kribi to Campo. National Road 9 comes south from Yaoundé via Mbalmayo and then to Sangmélima, Djoum, and Mintom. Finally, National Road 17 begins at Sangmélima and goes to Megong before crossing the border to Gabon. Other major roads cover the stretches between Mbalmayo and Ebolowa and between Kribi and Edéa in the Littoral Province. Of these, the route from Edéa to Kribi and from Ebolowa and Sangmélima to Yaoundé are paved. All other roads in the province are dirt, and thus subject to weather conditions. The South is also accessible via sea and air. The major seaports are Kribi and Campo, though Kribi is busier. Kribi is also the site of the regional airport. There are also airstrips at Ambam, Campo, Ebolowa, and Sangmélima. Tourism The South sees a good number of tourists due largely to its long, white-sand beaches. These run along the entire coastline, though the easiest to reach are at Kribi and Lobé. Kribi is the most popular destination due to its accessibility from Douala and Yaoundé via paved roads. It is also the largest beachfront town in the South, and it has an active nightlife and several large hotels. Undertow is a significant problem, however, and several bathers drown on Kribi's beaches
