The country consists of two main islands, Saint Kitts and Nevis, separated at a distance of 2 miles (3 km) by The Narrows strait. Both are of volcanic origin, with large central peaks covered in tropical rainforest. The majority of the population live along the flatter coastal areas. St Kitts contains several mountain ranges (the North West Range, Central Range and South-West Range) in its centre, where the highest peak of the country, Mount Liamuiga  can be found. Along the east coast can be found the Canada Hills and Conaree Hills. The land narrows considerably in the south-east, forming a much flatter peninsula which contains the largest body of water, the Great Salt Pond. To the southeast, in The Narrows, lies the small isle of Booby Island. There are numerous rivers descending from the mountains of both islands, which provide fresh water to the local population. Nevis, the smaller of the two main islands and roughly circular in shape, is dominated by Nevis Peak .
