One of the most beautiful views in the Cibao Valley, and in the world, is obtained from the historic eminence of Santo Cerro, an outpost hill of the central range, situated about three miles from the city of La Vega. From the foot of this hill the great plain stretches into the distance, meeting the azure sky on the eastern horizon, and far in the north skirting the brown slopes of the lofty Monte Cristi mountains, the more remote peaks of which are but faintly perceptible in their envelope of blue haze. A rich carpet of dark green overspreads the plain, where lighter spots indicate patches of tilled land and silver threads betray the presence of streams. The cities of Moca and La Vega are easily distinguished and on clear days even San Francisco de Macoris can be discerned. Clouds or rainstorms moving over portions of the vast expanse, add animation to the landscape. Columbus, gazing out upon the enchanting scene, was so impressed by its magnificence that he gave the great vale the name it still bears--La Vega Real, The Royal Plain. To the south of the central range the number of plains is greater. The largest expanse of level land on the island is the great plain which forms the southeastern part of the Dominican Republic. It includes almost the entire region east of the Jaina River and south of the central range, being about 115 miles long by 30 miles wide. This Eastern Valley or Seibo Plain, as it is sometimes called, is covered with forests and broad savannas, the most notable of which are comprised in the series of prairies known as Los Llanos, the Plains. Two smaller and irregular plains are the arid Bani coastal plain, lying between the Nizao River and the Ocoa, with a length of 25 miles and a width ranging from 3 to 12 miles, and the Azua Valley, winding from Mt. Numero, near the Ocoa, to the Neiba River, a distance of 33 miles with a breadth of from 3 to 30 miles. The Neiba Valley, situated in the southwestern portion of the Republic between the Neiba and the Baboruco Mountains is more regular. It is part of the valley which stretches from Neiba Bay, in Santo Domingo, to Port-au-Prince in Haiti. The Dominican portion is 65 miles long by 12 miles wide, and over one-half of its area is covered by the waters of Lake Enriquillo. The peninsula south of the Baboruco Mountains is an uneven plateau. In the very center of the Republic, surrounded on all sides by lofty mountains of the central group, is Constanza Valley, rich but to-day almost inaccessible. No less rich, but many times larger, is the other interior plain, known as the Eastern or Central Valley, a succession of fertile valleys, extending from the Neiba River to St. Raphael, almost 115 miles, with a width of from nine to twenty miles. The entire plain is claimed by the Dominican Republic, but more than half is in possession of Haiti.
